Definitions
- the invention relates to a pack for lumpy packaged goods with a casing, which is formed from a flat, foldable and multilayer packaging material, of which two strip-shaped edge zones for forming the casing in a connection area by a seal, preferably a cold seal with one another are connected, with a strip-shaped tear-open area of the packing envelope starting from one of the two strip-shaped edge zones and extending essentially perpendicular to this edge zone.
- a pack of this type is known from the published PCT application WO 80/02827 (application no. PCT / AT 80/00017) by the applicant.
- this known pack which is advantageously made from a two-ply packaging material and / or is designed as a tubular bag pack, the side packs
- Edges of the tear-open area are formed by lines of weakness in the packaging material, along which the material tears when the package is opened.
- the beginning of the strip-like tear-open aid here lies in a doubling area of the packaging material, in the case of a tubular bag pack, for example, at one of its fin-shaped sealing points.
- weakening lines arranged in a special way on the packaging material in the said doubling area the tear-open element can be actuated without problems while maintaining the gas tightness of the packaging envelope.
- the production of packaging materials that contain lines of weakness is now relatively complex. Presentation of the invention
- the invention is based on the object of specifying a pack of the type mentioned at the outset, in which the packaging material used for the production of the pack has no or only to a very small extent weakening lines and which can nevertheless be easily opened by pulling off a strip-shaped tear-open area.
- the packaging material is composed of several layers, selected from the series paper, unstretched polyolefin film or film, aluminum film, film made of biaxially stretched polypro pylene, film made of biaxially stretched polyamide, film made of biaxially stretched polyethylene terephthalate and subcomplex of two or three layers of optionally the above materials, whereby from all neighboring different layers in the packaging material the one mentioned earlier in the series and in the case of adjacent layers of the same or the same material, which is thinner in each case closer to the packaged goods, and whereby a sub-complex is considered to be one between the layers of which there are bondings which are considerably stronger than the bonded bonds of the sub-complex and the other layers of the packaging material to one another, that the packaging Ackungsmaterial along the two lateral boundaries of the Aufiß area only in the strip-shaped edge zone notches or 1 in-line punchings and possibly lines of weakness, but outside this edge
- the bond strengths between the individual layers of the subcomplex peel strength values which are at least 50% higher, but preferably at least 70% higher than the peel strength values of the bond strengths of the subcomplex and the other layers of the packaging material with one another.
- the packaging material starts from the ends of the indentations or 1 in-line punching holes without the presence of lines of weakness along more or less parallel Lines ie tears along the imaginary side edges of the tear area.
- the notches or 1 internal punching punch reach at least as far as or into the connection area.
- the pack according to the invention is characterized in that the beginning of the tear-open area between the connecting area and the free edge of one of the packaging material edge zones forms the grip tab.
- the pack according to the invention is characterized in that a of the edge zone from which the tear-open area starts, the free packaging material edge is turned over at least within the tear-open area to form a fold.
- the package according to the invention is characterized in that the sealing layer of the connection area has a recess at at least one of the two interconnected packaging material edge zones at the location of the tear-open area for the purpose of forming or widening the grip tab.
- edge zone from which the tear-open area does not start has a cutout at the location of the grip tab starting from the free edge of this edge zone.
- the pack according to the invention is characterized in that within the tear-open area the sealing connection has a lower peel strength than in its other areas.
- the grip tab is formed by the beginning of the strip-shaped tear-open area.
- the sealing of the two interconnected edge zones in the tear-open area is peeled off.
- the package according to the invention is characterized in that the packaging material edge zones connected to one another by the strip-shaped connecting area are separated from the packaging Edging material edges or notches or 1 internal punchings are provided, starting from the edge of the fold on the packaging material edge, whereby material from both edge zones forms the grip tab.
- the locations of the two indentations or punchings are connected to one another by an in-line material weakening in the packaging material, this in-line material weakening preferably within the connection area of the two strip-shaped Marginal zones.
- the pack according to the invention is characterized in that it is a tubular bag pack in which the two packaging material edge zones are connected to one another on their inner sides and thereby form the tubular bag longitudinal sealing seam, which is folded over onto the surface of the pack envelope , the tear area starting from the edge zone lying outwards at the folded longitudinal sealing seam.
- This packaging material consists of the outside of the pack - made of a 0.007 to 0.009 mm thick, printed aluminum foil, a paper of 30 to 100 g / m 2 and a latex-based cold adhesive coating applied in the profile (2 to 7 g / m 2 solid) .
- the paper forms the mechanical carrier layer of the composite material and the aluminum foil the layer that the Ensures gas tightness of the composite.
- FIG. 1 now shows schematically a perspective view of a tubular bag pack for wafers produced in this way.
- the stamped incisions 4, which extend from the edge 5 of the edge zone 2 and extend into the connection area 1, can be seen on the edge zone 2 of the packaging material, which zone is located outward. Between these two incisions 4, the material of the edge zone 2 forms a grip tab 5, which extends from the edge 5 to the connection area 1 and is large enough to be able to be handled to open the package.
- the packaging envelope now has a strip-like shape Tear-open area 7, the lateral boundaries of which are imaginary lines 8 on the packaging envelope, which form continuations of the incisions 4.
- Fig. 2 shows the pack in an analogous representation as in Fig. 1, but now in the half-opened state.
- the two zones 10 of the separated cold seal can now be seen.
- the opening in the packaging envelope is enlarged to such an extent that the packaged goods can be removed without the structure of the packaging envelope being destroyed by the opening of the package.
- the two-layer packaging material used according to this example which - starting from the outside of the pack - essentially consists of an aluminum foil and a paper layer (the thin adhesive layers are not considered as a special layer here) approximately longitudinally the imaginary parallel lines 8, which form the imaginary lateral edges of the tear area, tears.
- a packaging material is used in which the paper layer on the outside of the pack and the aluminum foil on the inside of the pack are used: when the otherwise identical pack is opened, the packaging material tears longitudinally starting from the incisions 4 two lines that meet at a more or less acute angle; this creates an inadequate opening in the packaging envelope.
- a sub-complex is considered to be a bond between the layers of which are considerably stronger than the bond between the sub-complex and the other layers of the packaging material.
- the first three materials are bonded to a peel strength of 5.3 N / 15 mm and form a subcomplex, which in turn is connected to the innermost OPP film with a peel strength of 2.6 N / 15 mm.
- the peel strength values mentioned each mean the mean tear strength i N / 15 mm, carried out according to a measurement method as described in "Packaging Review” 9/1978 (pages 72 and 73).
- Fig. 3 shows a variant of the package according to FIG. 1 in a partial representation in the supervision, the package cover being broken open at the location of the tear-open area 7.
- the sealing layer 11 of the connecting area 1 has a recess 12 through which the sealing layer 11 here narrows un thereby the peeling of the tear-open area 7 is facilitated during the opening process. This measure also widens the grip tab.
- FIG. 4 shows, in an analogous representation as in FIG. 3, another pack variant in which the sealing connection has a weakened zone 13 at the position of the tear-open area 7, whereby the tear-open areas are peeled off during the opening process is facilitated.
- This weakened zone 13 can preferably be realized in that the cold adhesive coating has at least one of the two edge zones 2 or 3, for example arranged according to a regular grid, adhesive-free points, whereby the peel strength of the sealing connection is reduced.
- FIG. 5 A further packaging variant is shown in FIG. 5, likewise in a representation analogous to that in FIG. 3. With this in order to facilitate the handling of the grip tab, below this, in the bottom region 3 a of the edge junk ⁇ 5 1 budding cutout 14 is provided. These cutouts 14 are preferably punched out on the packaging machine at the same time as the cuts 4 are made from the edge of the incoming packaging material web.
- notches 4 can also be provided in the packaging material instead of the incisions 4 starting from the packaging material edge 5. Because of the punching waste that occurs, the making of such notches is in most cases more complex than in the case of pure punching, but the handling of the grip tab is generally made easier by the notches.
- FIG. 6 shows, for a variant of the pack according to FIG. 1, the two edges of the packaging material in a partial representation in section along one of the two incisions.
- the upper edge zone 15, from which the tear-open area starts, is longer than the underlying edge zone 16 and has a fold 17 fixed at its free packaging material edge by a cold seal.
- the incisions 18 extend over the entire fold 17 and on the upper edge zone 15 into the connection area 19.
- the fold 17 now forms a particularly easy-to-use grip tab in the area between the two incisions 18.
- the fold 17 is continuously folded over and fixed by sealing directly in front of the packaging machine at one of the edges of the packaging material web pulled off the roll, after which the two incisions 18 are made.
- the further production of the pack is then carried out analogously to that described in connection with FIG. 1.
- FIG. 7 shows in section or in a perspective partial representation a wrapping package as it is mainly used for baked goods such as waffles.
- This pack has a packing envelope made of flat, foldable packaging material, on which two edge zones 20 and 21 overlap and are connected to one another in a connection area 22 by an adhesive layer 23.
- two cuts 24 are provided, which extend from the packaging material edge 2 into the connection area 22, a grip tab 2 being formed between the two cuts 24.
- the package is opened - analogously to that described with reference to FIGS. 1 and 2 - by pulling off the grip tab 2 in the direction of arrow 27.
- the two incisions te 28 are attached to the two interconnected edge zones 29 and 30.
- Fig. 8 shows the pack in a partial view in the supervision and
- Fig. 9 is an analogous presen- tation, however, at the location of the tear-open area di package cover is shown broken.
- the bottom edge zone 30 has a line of weakness 32 running between the locations of the two incisions within the sealing layer 31 and parallel to this, for example, by several short, by mate Rial Hampshiren separate punchings in the packaging material can be realized.
- the incisions 28 and the weakening line 32 are punched into the packaging material web immediately before this packaging machine is fed.
- the material now forms the two edge zones 29, 30 in the region between the two incisions 28 di grip tab, when the packaging material is pulled off, the packaging material is first torn open along the weakening line 32. Then we open with peeling off the remaining area 33 of the sealing connection and with tearing of the packaging material - along approximately mutually parallel lines analogously as described with reference to FIG. Fig. 10 shows this pack in perspective view in the half-open state.
- the essentially gas-tight and easy-to-open package according to the invention can, advantageously in the form of a tubular bag, advantageously be used for packaging chocolate, waffles or the like.
