Description

The present invention relates to a method for packaging a packaged goods, in particular a product stack formed with several Gutstückap. Furthermore, the invention relates to a packaging for a packaged goods.

Although the present invention is applicable to a variety of goods and goods to be packaged, the present invention and the problems underlying it will be described in more detail below with reference to the packaging of a stack of goods in the form of a laminated core formed from individual stacked metal sheets.

If a stack of stacked metal sheets transported by the manufacturer or dealer to a customer or the stack must be stored before, it is desirable to protect the stacked sheets during transport or storage from dirt and moisture in particular, so that the goods Customers achieved in a condition of impeccable quality. In the case of metal sheets, in particular, it should be prevented that the sheets begin to corrode. In the case of galvanized steel sheets or objects, for example, the aim is to avoid the formation of unsightly white rust on their surface. In order to prevent the entry of dirt and moisture, the laminated core can be surrounded with an airtight packaging wrapper to make a supply moister Prevent air masses from the storage or transport environment.

FR 0 249 534 discloses a method for packaging a packaged good.

In the DE 35 21 416 A1 For example, a method has been described for tightly packaging a stack of goods on a pallet. In this method, a shrink hood pulled over the stack of goods is progressively shrunk in the vertical direction using hot gas. Finally, the shrink hood is sealed with a foil, which is located between the stack and the pallet and protrudes beyond the edge of the pallet.

However, such known methods for packaging goods have the disadvantage that manual opening of the finished package is difficult and requires a tool such as a knife or the like. This is especially the case when the packaged goods are sheets with possibly sharp edges and corners and the use of a somewhat stronger and more tear-resistant packaging material, such as a thicker foil, therefore seems expedient.

The object of the present invention is thus to provide a method which makes it possible to package a packaged goods in such a way that the packaged goods are protected on the one hand against the ingress of dirt and moisture and on the other hand the packings are opened by hand in a simple manner without tools can. It is another object of the present invention to provide a corresponding packaging for a packaged product.

This object is achieved by a method for packaging a packaged goods with the features of claim 1 and by a package for a packaged with the features of claim 13 solved.

• Bereitstellen eines Tragelements, insbesondere einer Palette, zum Tragen des Packgutes;
• Auflegen eines ersten Packmaterialbogens auf das Tragelement;
• Anordnen des Packgutes auf dem ersten Packmaterialbogen in der Weise, dass ein Abschnitt des ersten Packmaterialbogens zwischen dem Tragelement und dem Packgut zu liegen kommt und dass der erste Packmaterialbogen über das Packgut übersteht;
• Auflegen eines zweiten Packmaterialbogens auf eine Oberseite des Packgutes in der Weise, dass der zweite Packmaterialbogen über das Packgut übersteht; und
• bereichsweises Verbinden des ersten Packmaterialbogens mit dem zweiten Packmaterialbogen.

Accordingly, a method for packaging a packaged product, in particular a stack of goods formed with a plurality of Gutstapels, proposed, comprising the following steps:

• Providing a support element, in particular a pallet, for carrying the packaged goods;
• Placing a first packing material sheet on the support element;
• Arranging the packaged goods on the first packaging material sheet in such a way that a portion of the first packing material sheet between the support member and the packaged goods comes to rest and that the first packing material sheet projects over the packaged goods;
• Placing a second packing material sheet on an upper side of the packaged goods in such a way that the second packing material sheet projects beyond the packaged goods; and
• area-wise joining of the first packing material sheet with the second packing material sheet.

In the area-wise bonding, the first packing material sheet and the second packing material sheet are adhesively detachable and in particular reconnectably connected in a respective predetermined first area along a first portion of a circumference of the support element.

Further, according to the invention, a packaging for a packaged product, in particular for a stack of goods formed with several Gutstapel, is provided, which is produced in particular by means of the method according to the invention. The packaging has a support element, in particular a pallet, for carrying the packaged goods. Furthermore, the packaging has a first packaging material sheet and a second packaging material sheet, wherein the first and the second packaging material sheet are partially connected to one another. The first packing material sheet and the second packing material sheets are adhesively detachable and in particular reconnectably connected in a respective predetermined first area along a first portion of a circumference of the support element.

The idea of the present invention is to connect the first and second dunnage sheets along two different portions of the circumference of the support member in different ways. While the two Packmaterialbögen along the first portion of the circumference in the first area are adhesively and detachably connected to each other, the connection along the second portion is such that the two Packmaterialbögen can be solved by destroying the packaging of the pack again from each other. Due to the releasable adhesive bond along the first section, on the one hand a tight connection of the packing material sheets is achieved, on the other hand the mutually adhering first regions of the two packing material sheets can be detached from one another manually to open the packaging along the first section. A different kind of connection of the first and second packing material sheets along the second portion of the circumference of the support element preferably contributes to the fact that the two packing material sheets do not detach in an unpractical manner when opening the packaging completely. In particular, the forces required to separate the first dunnage sheet from the second dunnage sheet along the second portion are substantially greater than those necessary to peel off the two dunnage sheets in the first region along the first portion.

Furthermore, the joining of the first and the second packing material sheet in the first region can in particular be effected in such a way that the packing material sheets can be reconnected in the first region, for example by re-adhering to one another. This is also advantageous, because if it is in the packaged goods to a good stack, it can be removed from the packaging in a simple manner, only a portion of the packaged goods. For a continued storage of the remaining, to be taken at a later time good, the packaging can be quickly and easily sealed again corrosion-resistant. In addition, advantageously, it is also possible to inspect the stored or transported packaged goods and to subsequently seal the packaging in a corrosion-resistant manner. This is also advantageous if the packaged goods are not, for example, a stack of goods but a single piece such as a machine.

Advantageous embodiments and further developments of the invention will become apparent from the other dependent claims in conjunction with the accompanying figures of the drawing.

In one embodiment of the invention, the respective first region is edge regions of the first and second packaging material sheets. Likewise, in this embodiment, the respective second region is likewise edge regions of the first and second packaging material sheets. As a result, packaging material can be advantageously saved and economical packaging of the packaged goods can be achieved.

In a further embodiment of the invention, a part of the first packing material sheet projecting beyond the packaged goods is folded away from the carrying element towards side surfaces of the packaged goods. In particular, in this embodiment, when connecting the first packaging material sheet to the second packaging material sheet, an underside of the first packaging material sheet in the first and second regions is overlapped with an underside of the second packaging material sheet. As a result, for example, a more attractive appearance of the packaged packaged goods can be achieved.

In another embodiment of the invention, a part of the first packing material sheet projecting beyond the packaged goods is folded away from the packaged goods to side faces of the carrying element. In particular, in this embodiment, when connecting the first packaging material sheet to the second packaging material sheet, an upper side of the first packaging material sheet in the first and second regions may be overlapped with an underside of the second packaging material sheet. In this way, in addition, penetration of, for example, water between the first packing material sheet and the support element can be avoided, which may be favorable in the case of a wooden support element.

In a further improvement, the first packing material sheet along the first portion of the circumference of the support member is additionally connected to the side surfaces of the support member. By this measure, the subsequent opening of the package can be facilitated by manually releasing the first packing material sheet of the second packing material sheet, since a holding of the first packing material sheet by hand is not necessary.

According to one embodiment of the invention, the first packing material sheet for joining with the side surfaces of the support member by means of a blunt mandrel is stitched to the side surfaces of the support member or attached by means of staples. Through this development, a rational and nevertheless reliable attachment to the side surfaces of the support element can be achieved. But other types of stapling or quilting are possible.

In one embodiment of the invention, a double-sided adhesive tape is applied in the respective first area to the first packaging material sheet or to the second packaging material sheet for adhesive bonding along the first portion. The connection in the first region can thereby be effected in a cost-effective manner. Furthermore, the use of double-sided adhesive tape allows a locally very flexible choice of position and extent of the first area, which may be of particular advantage when packaged goods or stacks of very different sizes, for example, stacks of different cut sheets, to be packed successively. The double-sided adhesive tape can be glued on site as needed in the packaging process. Furthermore, the adhered amount of the double-sided adhesive tape can be varied to adjust the force to be applied to release the joint in the first area.

In another embodiment of the invention, the first packing material sheet and / or the second packing material sheet for adhesive bonding along the first portion of the circumference of the support member are coated with an adhesive at least in the respective first region. On a separate tape can be dispensed with. If only a part of a respective surface of the first and / or the second packing material sheet, in particular in the respective first area, coated with adhesive, then also sticking one or both of the Packmaterialbögen to the packaged, such as the sheets, avoided and the Removal of packaged goods are made possible. This refinement can also be used to reliably prevent adhesive traces from remaining on the packaged item after removal from the pack. Alternatively, in this embodiment, the first and second packing material sheets can also be provided with different coatings, which are formed such that only at a mutual Touching these two coatings an adhesive effect is achieved.

In yet another embodiment, the first packing material sheet and / or the second packing material sheet for the adhesive bonding along the first portion of the circumference of the support member are formed self-adhesive at least in the respective first region. This can be achieved in particular by a suitable choice of material for the respective packing material sheet. For example, a packing material sheet or both may be formed as an electrostatically charged film or as a film which already has favorable adhesion properties without adhesive coating. In this way can be dispensed with adhesive tapes and adhesive coatings. The method can thus be carried out in a particularly simple manner and a combination of particularly good tightness can be achieved.

According to an improvement of the invention, the partially overlapping first and second dunnage sheets in the first region are pressed against each other and against the side surfaces of the support member or against the side surfaces of the package to assist the adhesive bond. This pressing can be effected, for example, by means of a rotating roller guided along the respective side surface, an equally rotating rotary round brush or else a flat brush brushing over the upper side of the second packing material sheet along the first section of the circumference of the support element. Thereby, a clean adherence of the packing material sheets to each other in the first area can be ensured, which in turn can improve the tightness of the connection along the first portion of the circumference of the support element.

In one development of the invention, the first packaging material sheet and the second packaging material sheet are joined together by joining along the first portion and along the second portion substantially along the entire circumference of the support member. Thereby, a tight closure along the entire circumference of the support element can be brought about.

In one embodiment, vertically extending folds, which are formed there by excess material of the first and second packing material sheets, are applied flat to the packaged goods and / or to the carrier element and attached to the outside of the second packing material sheet. This attachment can be done for example by applying an adhesive to the fold before applying, by sticking a double-sided adhesive tape on the fold before applying this or by pasting over the edge of the fold with a single-sided adhesive tape. As a result, the wrinkles at the corners do not stand off, do not interfere with storage and can not flutter during transport.

According to one embodiment, after the first packing material sheet and the second packaging material sheet have been joined, the packaged item is enclosed on all sides and in particular in an air-tight and moisture-tight manner. This is for a protection of the packaged goods against the ingress of moisture and dirt of particular advantage.

In an advantageous improvement of the invention, a moisture-binding substance and / or a volatile at a storage temperature of the packaged material, corrosion-inhibiting chemical is introduced between the packaged product and the first packing material sheet and / or between the packaged and the second packing material sheet. Alternatively, in this improvement the first and / or the second packing material sheet are provided on a surface facing the packaged goods at least in sections with such a substance and / or such a chemical or contain same. Moisture-binding substances within the packaging are advantageous, in particular in the case of an airtight sealing of the packaged goods in relation to the outside atmosphere, since they allow a largely dry atmosphere to be obtained within the packaging. Even if then the together with the packaged, for example, the laminated core, trapped air mass by low Außentem-, temperatures, for example, in a truck transport in winter, cools, the settling of condensation moisture can be avoided on the packaged below the dew point. Corrosion-inhibiting chemicals, for example so-called VCIs (volatile corrosion inhibitors), allow the build-up and longer-term preservation of a protective, corrosion-inhibiting atmosphere between the packing material sheets and, for example, the packaged sheets, through outgassing during the transport and / or storage period.

In one embodiment of the invention, the first and / or the second packing material sheet are formed with a plastic film. The plastic film may in particular be welded. Plastic films provide good protection against moisture and also dust and allow the production of dense connections.

In an alternative embodiment, the first and / or the second packing material sheet can also be formed with a paper, in particular a plastic-coated and / or fiber-reinforced paper. In addition, it may be appropriate to choose different materials for the first and the second packing material sheet.

In one embodiment of the invention, the support element is designed as a transport pallet made of wood, plastic or metal. This allows easy handling of the packaged packaged goods, for example by means of a truck. In particular, it may also be a pallet with standardized dimensions, which may prove advantageous during transport and storage of the packaged goods.

The above embodiments and developments can, if appropriate, combine with each other as desired. Further possible refinements, developments and implementations of the invention also include combinations of features of the invention which have not been explicitly mentioned above or described below with regard to the exemplary embodiments. In particular, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention.

The present invention will be explained in more detail with reference to the exemplary embodiments indicated in the schematic figures of the drawing.

In the figures of the drawing, the same reference numerals designate the same or functionally identical elements and features, unless indicated otherwise.

FIG. 1 illustrates the implementation of a method for packaging a packaged product 1 according to a first exemplary embodiment of the invention on the basis of an exploded view. For packing the packaged goods 1, which is in FIG. 1 As a one with a plurality of Gutstücken 1a, of which for clarity, only one is provided with a reference numeral, for example, a plurality of similar metal sheets, formed stack of goods is shown, a support member 2 is first provided. The support element 2 serves to carry the packaged goods 1 and can in particular comprise a pallet, for example made of plastic, wood, metal or another suitable material. Then, a first packing material sheet 3 is placed on the support member 2, for example, as in FIG. 1 illustrated, viewed along a vertical direction Z, from above. The first packing material sheet 3 may be, for example, a sheet of plastic-coated and preferably fiber-reinforced paper or a plastic film of suitable thickness and tear strength. Subsequently, the packaged product 1 is arranged on the first packing material sheet 3. For this purpose, the packaged goods 1 can be placed as a whole stack of goods on the resting on the support element 2 first packing material sheet 3, or the Gutstücke 1a can be placed individually. Preferably, the packaged product 1 is placed such that it does not protrude laterally beyond the support element 2, although a lateral projection of the packaged product 1 via the support element 2 is possible. After arranging the packaged goods 1 on the first packing material sheet 3 is an in FIG. 1 indicated in double dashed line indicated portion 4 of the first packing material sheet 3 between the packaged product 1 and the support member 2. Parts 5a-5d of the first Packmaterialbogens 3 are about the packaged 1 over. The parts 5a-5d also hang laterally over the support member 2 down, if the first packing material sheet 3 is dimensioned sufficiently large. In a next step, a second packing material sheet 6, which may be formed from the same material as the first packing material sheet 3, placed on a top 7 of the packaged goods 1. Here are parts 8a-8d on the packaged over and hang from the top 7 of the packaged product 1 side down. The second packing material sheet 6 can also be formed, for example, with a plastic-coated and preferably fiber-reinforced paper or with a plastic film. The two Packmaterialbögen 3 and 6 can be made transparent or non-transparent as desired or printed with information or handling instructions or the like.

Subsequently, the first packing material sheet 3 is partially connected to the second packing material sheet 6. This joining takes place along two sections 11, 12 of a circumference of the support element 2, wherein FIG. 1 the first portion 11 of the circumference in dotted line, the second portion 12 are indicated in dash-dotted line. In the first embodiment shown, the two sections 11, 12 each extend approximately along the half of the circumference, wherein they adjoin each other approximately in the middle of two opposite side surfaces 13b, 13d of the support element 2. The other two, also opposite side surfaces of the support member 2 are denoted by the reference numerals 13a, 13c. Thus, the first and second portions 11 and 12 are common to that in FIG FIG. 1 The first and second sections 11, 12 may, however, also extend over different sized portions of the circumference of the support element 2. So could the first section 11, for example, limited to that part of the circumference of the support member 2, which is associated with the side surface 13c. In this case, the second portion 12 may extend over the side surfaces 13d, 13a and 13b. On the other hand, however, the first portion 11 can also be chosen to be larger and include the circumference of the support element 2 in the region of three side surfaces 13b, 13c, 13d, while the second portion 12 remains limited to the fourth side surface 13d.

The joining of the first packing material sheet 3 with the second packing material sheet 6 takes place along the first portion 11 in a respective predetermined first, in FIG FIG. 1 dotted area 14 of the first dunnage sheet 3 and the second dunnage sheet 6. Further, the joining takes place along the second portion 12 in a respective predetermined second, in FIG. 1 hatched area 15 of the first dunnage sheet 3 and the second dunnage sheet 6. The two dunnage sheets 3 and 6 are joined according to the first embodiment of the present invention in the first region 14 in a manner which depends on the type of joint in the second region 15 is different. Along the first section 11, the dunnage sheets 3 and 6 are adhesively bonded together in the first region 14. This adhesive bond in region 14 is dense on the one hand, for example against the ingress of moist air, dust and water, and on the other hand releasably formed, in particular such that the two Packmaterialbögen 3 and 6 along the portion 11 after or during transport or storage To open the packaging from each other can be easily solved by hand. In other words, a person can deduct the two in the first region 14 adhering to each other Packmaterialbögen 3, 6 with a manually easily manageable effort. Thus, no knife or the like is necessary to gain access to the packaged packaged goods 1. It is furthermore particularly advantageous if the connection in the first region 14 is made such that the first and the second packing material sheets 3 and 6 can be reconnected to each other in the first region 14 after opening the package and preferably also tightly without the need for a tool. Thus, for example, during storage, the packaged goods 1 inspected or subsets of the packaged product 1, for example, several metal sheets 1a, removed and the packaging are then closed again in such a way that the packaged 1 or the remaining remaining packaged even before corrosion and Remain protected pollution.

On the other hand, the first packing material sheet 3 and the second packing material sheet 6 are joined together along the second portion 12 of the circumference of the support element 2 in the respective second region 15 such that the first and second packing material sheets in the second region 15 only by destroying the packaging again can be solved from each other. In particular, the connection in the second region 15 is formed in such a way that the forces to be applied to separate the first packing material sheet 3 from the second packing material sheet 6 along the second portion 12 are substantially higher than those forces required to detach the two packing material sheets 3 and 6 from each other in the first area 14 are necessary.

To open the packaging of packaged according to the first embodiment of the invention Packaged 1 thus the two Packmaterialbögen 3 and 6 in the area 14, possibly along the entire first portion 11, pulled apart by hand, whereby the adhesive compound dissolves there. With a suitable choice of the extension of the first and second sections 11 and 12, for example, in the manner as indicated in Figure 1, then the upper, second packing material sheet 6 a piece in the direction of arrow 16 are beaten back over the packaged goods 1. As a result, a convenient access to the packaged product 1 is achieved and individual Gutstücke 1a can be removed. The connection in the second area 15, which can not be loosened without destroying the packaging, assists the practical and convenient opening and knocking back of the second packing material sheet 6 and avoids unwanted complete detachment of the two packing material sheets 3, 6 in this case. The two Packmaterialbögen 3, 6 can thus be easily opened and repulsed by a person even with larger packaged goods without the Packmaterialbögen get confused.

In FIG. 2 the packaged goods 1 packaged in accordance with the method according to the first exemplary embodiment of the invention are shown in a cross-sectional view. According to the first exemplary embodiment, the parts of the first packing material sheet 3 protruding beyond the packaged goods 1, of which those in FIG FIG. 2 By way of example, only the two parts 5a, 5c are visible, folded away from the packaged product 1 and folded or folded toward the side surfaces of the support element 2. As FIG. 2 Here, for example, the protruding part 5c of the first packing material sheet 3 is folded down toward the side surface 13c of the support member 2, while on the opposite side of the support member 2, the protruding part 5a of the first packing material sheet 3 is folded against the side surface 13a of the support member 2 , As a result, in particular when connecting the first packing material sheet 3 to the second packing material sheet 6, an upper side 17 of the first packaging material sheet 3 in the first region 14 and the second region 15 can be brought into overlapping contact with an underside 18 of the second packaging material sheet 6.

FIG. 3 shows the packaged by the method according to the first embodiment packaged 1 1 in a plan view, ie along the vertical direction Z seen from above. As FIG. 3 can be seen, the packaged product 1 and the support member 2 in the plan view here by way of example substantially rectangular, the method of the invention, however, is also applicable to support elements and packaged goods other form and in particular can also find application, a quite irregularly shaped packaged to For example, sheet metal panels with an arbitrarily cut outer edge, to be packaged on a pallet that is essentially rectangular in plan view. The support element 2 and the packaged goods 1 are in FIG. 3 covered by the two Packmaterialbögen 3, 6 and are therefore only indicated by dashed lines. The first packaging material sheet 3 placed on the carrier element 2 and the second packaging material sheet 6 placed on the packaged article 1 are preferably made of a flat material which, as already explained, can be formed with a suitable paper or a suitable film, for example of a roll is handled, separated. As a result, for example, in the region of the corners of the support element 2 and depending on the shape of the packaged product 1, a fold can also result in the region of the corners of the packaged product 1 due to surplus material. In FIG. 3 For example, the folds 19a-d result. The packing material sheet 3 preferably projects beyond the packaged goods 1 in the area of all side surfaces 13a-d. Likewise, the packing material sheet 6 is preferably placed such that the packaged product 1 is completely covered in its circumferential direction. In this way, the packaged product 1 can be enclosed on all sides and, in particular, in a manner that is impermeable to air, dust and moisture, after joining the first packaging material sheet 3 with the second packaging material sheet 6.

FIG. 4 serves to illustrate a method for packaging a packaged product according to a second embodiment the invention. The method and the packaging produced by the method according to the second embodiment have all the features of the first embodiment of the invention, therefore, they are denoted by the same reference numerals as in those and their description will be omitted below. However, in the method and packaging in accordance with the second embodiment, a double-sided adhesive tape 21 is now used to make the adhesive and releasable connection in the first region 14 along the first portion 11 of the periphery of the support member 2. In FIG. 4 is the application of the double-sided adhesive tape 21 in the first region 14 in a detail A, the position lies within the first portion 11 and in FIG. 2 is indicated. The double-sided adhesive tape 21 can already be attached to the support element 2 in the predetermined first region 14 of the first packing material sheet 3 on the top 17 by gluing prior to placing the first packing material sheet 3. Alternatively, the sticking of the adhesive tape 21 to the upper side 17 can also take place only after the first packing material sheet 3 has been placed on the support element 2. Preferably, on the second adhesive side of the adhesive tape 21, which is provided for sticking to the underside 18 of the second packing material sheet 6 in the first region 14, a protective cover sheet (not shown) is left, which is only removed when the packaged product 1 is arranged completely on the first packing material sheet 6, the second packing material sheet 6 has been placed on the top 7 of the packaged goods 1 and the connection is to take place along the first section 11. In order to support a tight connection between the first regions 14 of the packing material sheets 3 and 6, it may be advantageous to press these regions 14 against one another in the direction of arrow 22. This can be done by means of a rotating roller, a rotating round brush or also, as in FIG. 4 shown as an example by means of a flat brush 23 guided along an upper side of the second packing material sheet 6. Preferably, the double-sided adhesive tape 21 is adhered in this embodiment of the invention in the region 14 along the entire section 11 continuously on the top 17 of the first packing material sheet 3 in order to achieve the most dense and detachable completion. As an alternative to the above, the double-sided adhesive tape 21 may also be first glued in the first region 14 of the second packing material sheet 6 on the underside 18, after applying the second packing material sheet 6 on the packaged 1 a possibly provided cover strip on the other adhesive surface of the adhesive tape 21 withdrawn and then the connection of the two Packmaterialbögen 3, 6 are produced. In the first region 14, the upper side 17 of the first packaging material sheet 3 and the underside 18 of the second packaging material sheet 6 thus touch each other through the intermediary of the adhesive tape 21.

A method and a package according to a third embodiment are shown in FIG FIG. 5 based on a detail A ', which is also in FIG. 2 is indicated clarifies. Also, the third embodiment includes all the features of the first embodiment, so that the same reference numerals are used here. The difference of the third compared to the first and the second embodiment of the invention is that now, as FIG. 5 shows that the adhesive bond is made by coating the top 17 of the first dunnage sheet 3 and the bottom 18 of the second dunnage sheet 6 along the first portion 11 in the respective first region 14 with a suitable adhesive. This coating can be done either before cutting the packing material sheets 3, 6 or even during the packaging of the packaged product 1, for example, after both Packmaterialbögen 3 and 6 already are done. The adhesive coatings are in FIG. 5 provided with the reference numerals 24 and 25. It may also be advantageous and sufficient for a tight connection to provide only one of the coatings 24 or 25. Preferably, the first packing material sheet 3 along the portion 11 of the circumference of the support member 2 in the first region 14 on the upper side 17 is provided with an adhesive coating 24, while dispensing with the adhesive coating 25. Instead, it is also possible for the coating 25 to be applied and for the coating 24 to be left out. Moreover, it is possible to coat the upper side 17 of the first packing material sheet 3 or the underside 18 of the second packing material sheet 6 or both over the entire surface with adhesive, whereby a particularly secure adhesive connection can be achieved, but also sticking to the packaged product 1 can occur. The adhesive used for the coatings 24 and / or 25 is chosen according to this third embodiment of the invention such that the connection of the packing material sheets 3 and 6 in the first region 14 releasably and in particular by renewed juxtaposition and pressing is adhesively recoverable , This allows easy opening of the package without tools and also a convenient and easy reclosing. As in FIG. 5 also shown according to the third embodiment of the invention, a pressing in the direction 22, wherein for this purpose in FIG. 5 an example of a rotating roller 26 is shown.

The FIGS. 10 and 11 illustrate the packaging of a packaged goods 1 'with Gutstücken 1a' according to a sixth embodiment of the invention. Also in the sixth embodiment, a support member 2 'is provided, on which a first packing material sheet 3' is placed. On the first packing material sheet 3 ', the packaged product 1', as in relation to FIG. 1 described, arranged. The packaged product 1 ', the support element 2' and the first packing material sheet 3 'are further formed in the same manner as already described with respect to the first embodiment. According to the sixth embodiment of the invention, however, in contrast to the embodiments described above on the packaged product 1 'protruding parts of the first packing material sheet 3', of which in the figure, only the protruding parts 5a 'and 5c' are visible, of the support member 2 ' folded away and folded in the direction of arrow 36 'upwards, to side surfaces of the packaged goods 1', folded. Does the packaged goods 1 'flat pages, such as in the FIG. 10 shown packaged goods 1 ', whose side surfaces extend substantially along the vertical direction Z, then the protruding parts 5a', 5c 'can be advantageously applied to the packaged 1'. An upper side 17 'of the first packing material sheet 3' now faces the packaged goods 1 '. Now, a second packing material sheet 6 ', as also with respect to FIG. 1 already explained, placed on a top 7 'of the packaged 1'. Also according to the sixth embodiment of the invention, the first and second dunnage sheets 3 'and 6' are adhesively releasably and in particular reconnectably connected to each other along a first portion of a circumference of the support member 2 'and joined along a second portion of the circumference of the support member 2' in that they can only be detached from one another there by destroying the packaging. The joining of the packing material sheets 3 ', 6' can in the same manner as above with reference to the FIGS. 1 to 7 explained, wherein the sixth embodiment differs from the preceding embodiments in that when connecting the first packing material sheet 3 'with the second packing material sheet 6' with a bottom 37 'of the first packing material sheet 3' in first and second regions 14 ', 15' with a bottom 18 'of the second Packmaterialbogens 6 'is brought into contact overlapping.

In addition, there may be advantages in introducing a moisture-binding substance, for example a silica gel or the like, between the packaged product 1 and the first packing material sheet 3, 3 'and / or the second packing material sheet 6, 6'. This can be useful in the case of moisture-sensitive or hygroscopic packaged goods 1, 1 ', but it also proves to be favorable if the packaged goods 1, 1', such as a sheet stack, tend to corrode under the action of moisture. Instead of a moisture-binding substance, a volatile, corrosion-inhibiting chemical (also called volatile corrosion inhibitor or VCI) can be introduced. This can be achieved in that the first packing material sheet 3, 3 'at its upper side 17, 17' facing the packaged goods 1, 1 'and / or the second packing material sheet 6, 6' at its underside 18, 18 'at least in sections with a moisture-binding Provided and / or coated with a volatile, corrosion-inhibiting chemical. The outgassing of the corrosion-inhibiting chemical can be used to produce a protective atmosphere surrounding the packaged goods 1, 1 'within the packaging. Alternatively, the packaging for the packaged goods 1, 1 'produced in accordance with the embodiments of the invention described above can also be filled with a suitable protective gas for this purpose, before the joining of the packing material sheets 3, 3', 6, 6 'is completed. In addition, in all the aforementioned embodiments within the first section 11, the connection point of the Packmaterialbögen 3, 3 ', 6, 6' with a - not shown in the figures - seal, for example, a self-adhesive tear strip, are glued over, which tears open when opening the package. This can prevent that unauthorized removal of Gutstücken 1a, 1a 'remains undetected.

Although the invention has been described above with reference to preferred embodiments, it is not limited thereto, but can be modified in many ways without departing from the subject matter of the present invention.

In particular, the present invention is not limited to support elements in the form of rectangular pallets or cuboid packaged goods and stacks. On the contrary, packaged goods of other shapes can also be packed on rectangular or differently shaped carrier elements or documents by means of the method according to the invention.

In addition, it is also conceivable to provide not only a first and a second portion of the circumference of the support member, but it may also be appropriate, for example, two first and two second portions to arrange alternately, wherein the compound of the packing material sheets along the first and second sections as described above.
