Padded packaging bag

The invention relates to a padded 'packaging bag with top and bottom and three closed Edges and one that can be closed after filling the packaged goods fourth edge. It also relates to a method for the continuous production of padded packaging bags, each with a top and bottom and with a Foam layer on the inside of the bag and a layer of sheet material on the outside of the bag.

Padded packaging or shipping bags are used for post or other shipping of e.g. books, plastic or plastic products and other items used in the event of careless and improper handling can be damaged.

Numerous types of such padded mailing bags are currently in use. One such type of mailer, the so-called trapped air bubble bag, consists of a layer or layer of relatively stiff Paper on the outside and two layers of thin plastic wrap on the inside. The two layers of plastic film are glued together in such a way that a large number of evenly spaced air bubbles are inserted between them.

.609824 / 0616

conclude. This air cushion bag with padding by enclosed air bubbles is relatively cheap and light in weight, but has many disadvantages. For example, it can be relatively easy to handle, that the trapped air bubbles in the plastic layers of the bag are torn, so that the packaged goods there is little or no protection in the bag. In addition, the air bubbles break up along those edges where the inner plastic layers are folded to form the bag side edges and where the bag is at its edges is glued or welded, so that again little or no protection against damage is given.

Furthermore, in the case of the air cushion bag, the packaged goods are in the areas between the individual air bubbles through the thin plastic film only slightly protected. For example, if any "foreign object with a sharp corner or edge pushes or pushes against the bag in the spaces between the air bubbles, the sharp body hits or Object directly to the packaged goods in the bag.

Furthermore, the cushioning layer is included with the Air bubbles are thin and flexible, making the bag itself relatively stiff and strong enough for normal handling the paper on the outside of the bag must be relatively thick, e.g. approximately 27.2 kg (60 pounds) per ream. The air cushion bag is also relatively easy to tear. As soon as there is a Has formed a tear point, the tear can easily spread through the bag, so that the packaged goods in the Pouch may be damaged or destroyed.

In another currently used packaging bag, waste paper, fine, is used as a cushioning material distributed paper material, cotton waste, fabric waste or the like. Used. The waste material serves as a filler and is placed between two sheets or layers of paper. The paper is then folded and turned into one at the edges

509824/061 θ

Bags glued togetherUX reader bags also have numerous disadvantages. For example, the padding is relatively uneven and in many cases the finished pouch will have one rough or wrinkled outer surface. Also, so that the outer layer of the bag and the filling material are not damaged cannot leak, the bag can be made from relatively thick paper, approximately 27.2 kg (60 pounds) per egg. The padding or filling material is loosely between the layers of paper, so that if the Bag and cause a lot of inconvenience can. Some waste fillers are very fine-grained, so that if the bag is accidentally damaged Filling material falls on carpet or similar surfaces that Cleansing is difficult.

The filler cushion bag is, like the bubble bag, also relatively easy to tear, so that its contents are often exposed to the risk of damage is. Furthermore, when the filler cushioned bag is pressed together at the edges for the purpose of gluing the edges to the finished bag the cushioning layer in these areas is so strongly compressed that it is only more than a third The paper ply or layer acts so that protection is only given to a limited extent at the corners and edges.

Serve in another known packaging bag one or more layers of corrugated paper as a cushioning layer. The layers of corrugated paper are made out of proportion between two layers thick paper, and the pouches are cut from the laminate and molded. This packing bag however, has many of the same disadvantages as the bubble bag and the filler cushion bag. For example is the corrugated paper cushion bag against damage to his Edges and susceptible to tearing on its surfaces.

A foam-lined packaging bag has also been introduced, but with little success.

509824/0618

-4- 2A56 1

To make this foam liner bag will be a sheet of paper to be folded into a bag from a paper supply roll and a piece of foam from a foam supply cut off. These two layers are then placed on top of one another and fastened to one another, for example by gluing. The resulting bag blank is then folded into the finished bag. However, such bags are not suitable for continuous mass production, so that they are opposite to the bubble bag or the filler cushion bag are not competitive. Furthermore, manufacturing difficulties bring about a fine inconsistent appearance; often the foam material protrudes from the edge of the bag, resulting in an unsightly appearance. What is more serious, however, is that these bags are not protected at their lower edge. The contents of the bag are therefore susceptible to damage from objects hitting the bottom of the bag. In addition, the packaging items even if they have sharp corners, pierce the bottom of the bag from the inside, so that the bag contents possibly is lost or damaged.

The invention is based on the object of providing an upholstered bed which avoids the disadvantages of the prior art To create packaging bags and to specify a method for producing such a packaging bag.

A packaging bag of the type mentioned at the outset is characterized according to the invention by an outer layer made of relatively thin sheet material and an inner layer covering substantially the entire inner surface of the outer layer made of foam attached to the outer layer.

According to the invention, the manufacturing method is characterized in that a layer of foam material is continuous attached to a layer of relatively thin sheet material; that the laminated layers continuously folded so that the foam layer is on the inside of the folded laminate

S09824 / 0616

finds; that the folded laminate at predetermined spacings ten places is heat-sealed across its width; and that that The switched laminate is cut into individual padded bags along the individual heat-sealing seams.

The packaging bags are made from a laminate, that consists of a continuous layer of sheet-shaped foam, which is, for example, by means of an adhesive on a through a layer of relatively thin paper or another material with the same properties is attached, consists. The paper or the like. Material then forms the Outer surface of the finished bag.

According to one embodiment of the method, the laminate is folded so that at one end a padded envelope flap part arises, and the folded laminate is then heat sealed at predetermined points along its length, whereby the Outer edges of the bag are formed. Next, the individual bags are cut out of the continuous laminate. According to another embodiment, the bags are formed from two separate laminates attached to predetermined Places to be heat sealed, thereby forming the outer edges of the bag. Then the laminates are in cut up individual bags. With this procedure, no splitting of the laminate is necessary. After cutting the bag blanks can be done by further hot glueing the lower hand or the bottom of the finished bag.

The packaging bag remains open on one side for filling the packaging or shipping goods, and preferably is to close this open side after filling the Packaged goods are provided with the split flap. On the bag For example, a strip of pressure sensitive adhesive may be attached so that the split flap quickly and easily attaches to the bag will.

The invention is described below with reference to the drawing in individually explained. Show it:

Figure 1 illustrates the preferred method of making the padded packaging or shipping pouch. A web of foam material 20 and a web of relatively thin paper-like material 21 are continuously conveyed to a device by supply rolls 20 'and 21', respectively, which produces the shipping bags in different work steps from the two conveyed lanes. The two Web 20 and 21 are delivered to a pair of rollers 23, 24 by a loan of rollers 22 (only one of which is shown), where they are laminated together.

609824/0616

Before the passage between the rollers 23 and 24 is a glue or adhesive 25 is applied between the two strips. A spray gun 26 arranged between the two webs 20 and 21 sprays the adhesive 25 onto one or both lanes. In this way, the two webs 20 and 21 become as they pass between the rollers 23 and 24 glued and laminated together by the adhesive. Instead of this you can also attach one or more adhesive strips along the bands of the two tracks to glue the tracks together.

After passing through the rollers 23 and 24, the resulting laminate (indicated at 30 in Figure 1) using a conventional long fold or similar apparatus (not shown) folded lengthways. The folding takes place approximately at point A in Figure 1, the arrow indicating the way in which the laminate 30 is folded is displayed. The laminate can or can be folded in half to create the bag of Figure 2 to the side of the center line to obtain a pouch with a flap as shown in FIG. 3B. The production and the function of the flap will be explained in more detail later.

When the folded laminate continues to run by the device of Figure 1, the laminate is at predetermined spaced locations with the help of a number of Hot glue devices. The hot bonding areas are indicated at 31 in FIG. Using a conventional Cutting device (not shown) is then used to fold the laminate along the individual heat-sealing seams 31 cut into individual bags 32. The transport of the laminate through the heat-sealing and cutting stations takes place without interruption, but step by step, with each movement step depending on the number of existing ones Heat sealing and cutting stations, equal to the width of one or more finished bags.

If the laminate is folded in such a way that a flap is formed, you can touch the surface of the laminate

509824/0616

- ο -

a hot melt adhesive prior to cutting into individual bags 27 apply. This can be done in any known manner, for example by means of the application device shown in FIG 28 happen. The adhesive is applied to the outside of the laminate near the top of the bag blanks, so that to close the packaging bag for shipping the envelope flap part 35 folded over and on the Adhesive can be stuck. In order to protect the adhesive 27 until it is used, it is provided with a peelable protective strip 29 covered. As shown in Figure 1, the pulling up takes place of the protective strip 29 onto the adhesive 27 by any conventional dispenser 34. The adhesive 27 and the protective strip 29 can be applied to the layer 21 made of paper-like Material can be applied at any convenient time in the manufacturing process of FIG.

Figure 2 shows a single bag 32 without a flap. It consists of the layer of paper-like material 21 on the outside and the layer of foam 20 on the inside. The closed end or bottom 33 of the bag is formed by the folding process according to FIG. There is a heat seal seam on each of the two sides of the bag 32 31. The heat-sealing seams 31 should be approximately be twice as wide as desired for the finished bag 32. This leaves behind when the individual bags 32 are cut off or separated from one another, a sufficiently large pool of heat seal seam 31 on each finished bag.

The bag 32 shown in Figure 2 can be different for the safe transport and shipping of many objects Shape and made of different materials. After placing an item in the bag, the open end of the bag 32 heat-sealed, stapled or glued, so that a sealed shipping bag is created.

50982 4/0616

FIG. 3A shows a second embodiment of the shipping bag. The bag 32 'is similar to the bag of Figure 2 except that a flap is used to close the bag 35 is provided. The manufacturing process for the bag 32 * is essentially the same as that of Figure 1, except that the paper-like layer 21 is slightly wider from the Foam layer 20 ^ so that they over one edge laterally protrudes. Figure 4 shows, in solid lines, a cross-section of the one used to make the bag 32 ' Laminates.

The paper-like web 21 is wider than the foam web 20 by an amount that is equal to the required length of the envelope flap 35. Thus, when the laminate, as indicated by the arrows in FIG welded and the bag is cut off from the continuous row of bag blanks, a bag 32 ^f vender of the type shown in Figure 3A. Flat to the entry of the shipping goods in the bag 32 * you only need to fold the envelope flap 35 and staple it. For this purpose, the protective strip 29 is removed from the adhesive 27 before the envelope flap 35 is folded over onto the outside of the bag. In this way, the open end of the bag 32 is closed, and a one-piece, self-contained, padded shipping bag is obtained.

If there is no adhesive 27 on the Bag is attached, the gluing can be done in such a way that one on the envelope flap part 35 of the bag blanks attaches a hot melt or water active adhesive. This can be done with the aid of any conventional applicator (not shown) and in any Stage of the manufacturing process.

FIG. 3B shows a bag 32 "with a padded envelope flap 35 '. This bag is also made after the procedure produced according to Figure 1, but have the foam sheet

9824/06

and the paper-like web 21 of the same width, the envelope flap 35 'arises from the fact that, as indicated by dashed lines in FIG. 4, the fold line in the laminate is opposite the center line is offset. In this way, the flap 35 'receives a foam layer on its inside, so that the Shipping goods in the bag 32 "are completely surrounded and protected by a foam layer. By means of the adhesive strip 27 on the bag, it can be securely closed and glued relatively quickly and easily.

Figure 5 shows a further embodiment of the after Method according to Figure 1 produced bag. In this bag 32 "'there are two foldable flap parts 35". Each of these plate members 35 ″ is made in the course of the bag manufacturing process preferably coated with a hot melt or water active adhesive so that the two Flaps can be easily glued together by the user to form a sealed bag.

The bag 32 "» is made in a manner similar to the bag 32, 32 "and 32" except that the foam layer 20 is on both sides is narrower than the paper-like layer 21. Thus, when the laminate 30 is folded, two flap parts are produced.

Any foam material per se can be used for the layer 20, but is preferably used Polyethylene foam with which good results have been obtained. The foam layer is approximately 2.4 to 3.2 mm (3/32 to 1/8 of an inch) thick. The foam material has a myriad of tiny trapped air bubbles in its structure that give a cushioning effect. The foam layer itself is relatively stiff and therefore ensures for the required rigidity and stability of the bag, so that the finished bag with little risk of damage can be handled and transported.

The foam material gives a better cushioning effect than the air cushion bag, the filler

5 09824/0618

cushion bag tmä is given with the corrugated paper cushion bag. The foam material also provides better insulation against temperature changes that the bag may have during the It is subject to shipping and is tear-resistant and essentially moisture-proof.

The paper-like material used for the layer 21 is used preferably Kraft paper, this layer 21 being reactively thin can be. Because of the rigidity of the foam layer 20 can the paper-like sheet 21 can be much thinner than that for the bubble bag, the filler cushion bag and the corrugated paper cushion bag paper material used in the prior art. For example, according to the invention, paper can be used use approximately 13 »6 kg (30 pounds) per egg. Man therefore requires less paper material for the bag, so that the bag becomes cheaper.

The bag provides a large, secure, padded protection for items to be sent by post or otherwise. The bag has an attractive appearance and can be easily combined with the logo of the Be printed by the manufacturer. By using the foam inner layer, you get a lightweight, padded one Mailing bag that is pliable, tear-resistant and of uniform Thickness is.

Figure 6 illustrates another method of manufacture of the packaging and shipping bag according to the invention. This process uses two continuous foams layers 40 and 41 as well as two continuous paper-like ones Layers 42 and 43 “Each of the four layers can be used in their Width corresponds approximately to the length of a finished bag 50, since it is not necessary to fold the layers. However, if a padded flap 35 'is to be provided, As shown in Figure 7, the two upper layers 40 and 42 correspond approximately to the length of a finished bag,

50982Λ / 0616

while the two lower layers 41 and 43 to the dimensions the flap are wider.

The layers are made of foam and paper-like material each grouped into pairs, and with each pair becomes An adhesive 44 is applied between the two separate layers of the pair, so that two laminates 45 are formed. The adhesive 44 is sprayed on with a spray gun 46 which is similar to the spray gun 26 according to FIG. For gluing and laminating the two pairs of layers, a pair of rollers 47, 48 is provided. In the device of Figure 6 are the foam layer 40 with the paper-like layer 42 and the Foam sheet 41 is laminated with the paper-like sheet 43. As they continue through the device, the laminates 45 are heat-bonded (similar to the device according to FIG. 1) and cut into individual bags 50. G-if desired For example, a strip of hot melt adhesive 27 and a peelable protective strip 29 may be provided (Figure 7). That Adhesive and the protective strip are applied similarly to the device according to FIG.

FIG. 7 shows a bag 50 produced by the method according to FIG. 6. In contrast to the method according to FIG Figure 1, where the lower edge of the bag is formed by the switching operation, the lower handles of the bag 50 be heat-glued or otherwise connected. The lower edge 52 can be formed in the same way as the side edges 51 be heat-glued. The heat sealing of the lower edge of the bag 52 can be carried out at any convenient time during the Production of the finished bags is done. For example, heat sealing the lower tape 52 prior to formation or Gluing the side edges 51 (station A in Figure 6), before cutting into individual bags (station B) or after Cutting into individual bags 50 is done. The open end of the pouch 50 can be opened in the same manner as the pouches are closed according to Figure 3A and 3B.

509824/061 6

While it is possible, and in some cases preferable, to leave the straps of the bags of Figures 2, 3A, 3B, 5 and 7 as shown, with the sealed hands approximately parallel to the outer surfaces of the bag, in certain applications it is It is desirable to fold over the welded straps so that a somewhat smaller bag with rounded edges is created. FIGS. 8 and 9 show, in cross section, the edges of two finished bags 60 and ^1. In one bag 60, the welded edges 61 are unfolded (FIG. 8), while in the other bag 60 'the edges 61 are folded over (FIG. 9). The folding of the edges does not change the inner dimensions of the bag, but only increases the outer width (and possibly the length) of the bag. Any conventional folding apparatus can be used to fold the welded edge portion 61. A hot melt or pressure sensitive adhesive can be applied along those edge portions of one or both surfaces where the edge 61- 'is to be unfolded so that the application of heat and pressure can adhere the edge portion 61 to the surface of the bag 60.

Both the embodiment of Figure 8 with an unfolded as well as the embodiment according to FIG. 9 with a folded edge provide the basic advantages of the present invention. Both give additional protection to the edges of the bag against damage to the contents of the bag. Besides, the one is folded Bag 61 'a little smaller so that it can be stored and takes up a little less space during transport.

FIGS. 8 and 9 also make a further advantageous feature of the shipping bag clear. When the edges of the Bags are sealed using heat and pressure, the inner foam layers tend to form generally rounded inner edge regions 62 to fuse together. This gives an additional protection for the Shipped goods in a bag by placing objects with sharp edges or corners the upholstery material at the edges and corners

50 98-2 4/06 16

pierce the pouch less easily. Also is one More complete insulation to protect the contents of the bag against moisture and wetness. When the foam material melts together on all sides of the bag, so the inside of the bag is resistant to most external weather conditions isolated.

Figure 1 shows the preferably for welding or Device used for heat sealing the edges of the bag. the Device has two rollers 70 and 71 that run across the laminate (Figure 1) can be rolled back and forth so that & ie layers of the Laminates are welded or heat-bonded together at the predetermined spaced-apart locations. The roles 70 and 71 rotate on axles 72 and 73 and are driven by any conventional device (not shown) Because the bags are manufactured in continuous or assembly line operation are, the arrangement is such that the rollers 70 and 71 either move apart and return to a starting position or run back and forth across the laminate to perform a welding step and then up waiting for the next step movement of the laminate.

To ensure adequate sealing and in addition, to fuse the foam layers with one another at the edges, as shown in FIGS. 8 and 9 as advantageous As explained for the feature, the rollers 70 and 71 should preferably be heated. This can be done by means of electrical heating an internal circulating heating medium or others done conventionally.

To ensure that the bags pass through the rollers 70 and 71 perfectly and permanently welded and sealed are preferably brought in that area of the Laminates between the foam layers where the bag is sealed apply a strip of hot melt adhesive. This can be done before the folding process (station A in Figure 1) with the help of any conventional applicator

509824/0616

(not shown) happen. Using the Hot melt adhesive results in a better seal and insulation against moisture, as the two paper layers 21 are permanently merged with one another. The foam material becomes due to the pressure of the lumps and the effect of heat impressed along the weld seams.

An unexpected and extremely beneficial feature of the present mailer is that the open end stands up slightly so that the packaged goods are lighter can be filled. Although it is not clear why this is is the pail, it is believed that this effect arises from that the foam sheet during the lamination process is slightly stretched compared to the paper-like layer and after the completion of the bag endeavors to resume the original length dimension. Indifferent, For what exact reason, however, a bag produced according to the invention is naturally somewhat open, as in Figure 2, 3A, 3B, 5 and 7 shown. This effect can be due to intentional Stretch the foam sheet before lamination to the paper-like Material can be reinforced.

The fact that the bag is open makes it easier to find out how to fill it. If the bags are to be filled by machine, so designed this is the case when using bags that have already been opened a little, so that the machine continues to open the bags and the packaging ^ can type well, much easier and simpler.

Figure 11 shows an apparatus for performing a improved method of hot bonding or welding of the bag laminate while ensuring an integral weld of the foam material. The rolls 70 * and 71 ' of the device have beveled bands 75 and 76. When welding or heat sealing the laminate to form the bag blanks will be the top and bottom portions of the bag put together at a slightly divergent angle, and since the rollers in the area where the foam is located,

509824/06 16

overlap, a larger part of the foam is heated. This gives a better weld between the edges of the foam, and it is believed that thereby the Bag retains the ability to pop open even after long storage in the closed state and to close in this state stay.

The invention also makes it easier to put a company name on the bags. For this purpose, while the laminate is being transported through the device, a company-supplied logo or printing block inserted into a stamp or printer and the company name continuously printed on the bag. Suitable for this particularly those bag designs that have one or more foldable or glued flaps, for example those according to FIGS. 3A, 3B and 5.

The open end of the bag can also be provided with stiffening ribs, as shown in FIG. To this For this purpose, the web 21 of paper-like material is folded over at one or both edges when it is pulled off the roll attached by means of a hot melt or adhesive. When the paper-like web 21 is then laminated to the foam sheet 20 becomes a stiffer reinforced pouch. One can also put the foam sheet 20 over the ribbed one Allow part to overlap. However, the less such an overlap, the cheaper the bags in the Manufacturing as the amount of foam used is reduced.

So the above is an improved padded packaging or shipping bag, which contains the packaged goods during transport, shipping and handling or protects against damage during mailing and which consists of a continuous layer of foam material which is attached (laminated) to a continuous layer of relatively thin sheet material. The laminated layers

509824/0616

are folded so that the foam layer is on the inside is located. If desired, the laminated layers be folded so that at one end or on one side a (either padded or unpadded) flap part arises. The folded laminated sheets are then placed at predetermined locations along the continuous Laminates are heat-glued, glued or put together in a similar way. The folded laminate is then along the adhesive seams in individual padded bag blanks cut up. The resulting bag blanks are closed or glued on three sides, while one end is for the filling of the packaged goods remains open. Do the filling the open end of the packaged goods can be closed will. If the bag is provided with an envelope flap, the closing can be done by opening the envelope flap folds over the open end of the bag. About closing the pouch with the flap can be opened Apply a pressure sensitive adhesive to the outside of the bag where the flap will fold. The pressure sensitive adhesive is covered with a peelable protective strip that is peeled off when the bag is closed shall be.
