Abstract: A package includes a container and a lid, the lid being attached to the container edge by a sealing layer. The container wall, at least in the region of the container edge, has a depression formed toward the container interior.

Abstract: An element which is punched out in a cover shape for sealing of containers, includes two plies with at least one opening aid which is integrated within these plies, the ply (3) located in the direction of the container having a plastic layer which is provided with perforations or scoring. The layers of the sealing element are cemented by a peelable adhesive layer, the opening aid and the ply which has the plastic layer being free of adhesive in the area of its perforations or scoring. The sealing element enables not only facilitated sealing of food containers, such as microwave containers, since mutual displacement or slippage of the individual plies due to the adhesive layer is prevented, but that any type of penetration of adhesive into the food container, thus into the food, is prevented in any case by the peelability of the adhesive.

Abstract: A composite material (1) includes a carrier layer (2) and a sealing layer (3), the carrier layer being detachably connected to the sealing layer. According to the invention, a zone (5) of separation is formed between the carrier layer and the sealing layer, whereby at least the surface region (2?) of the carrier layer (2) that borders the sealing layer (3) includes non-polar substances and at least the surface region (3?) of the sealing layer (3) that borders the carrier layer (2) includes polar substances or at least the surface region (2?) of the carrier layer (2) that borders the sealing layer (3) includes polar substances and at least the surface region (3?) of the sealing layer (3) that borders the carrier layer (2) includes non-polar substances.

Abstract: A counterfeit-proof metal foil is textured in at least a given partial area of its surface, this partial area having a radiation refraction value which is different compared to the remaining surface area. The metal foil is suitable as a packaging material, among others for medications. The manufacturer or the consumer can check based on the given surface structure which is intended as an identification sign whether he has acquired an uncounterfeited product. If texturing takes place on most of the surface of the metal foil, this is identical to the appearance of a printed picture so that the metal foil as claimed in the invention is likewise used as a decorative foil or an advertizing medium.

Abstract: The invention relates to a process for producing a carrier material with at least one hidden identification mark which is attached in at least one surface region of the carrier material and which is then covered. The invention furthermore relates to articles containing this carrier material and its use for analysis of the identification mark(s). By the process as claimed in the invention a carrier material with hidden identification marks is made available, the use of which is given in a wide range, especially when the original state of goods is to be established. For the consumer itself the identification mark is not necessarily visible so that he is not unnecessarily upset, but rather is confronted with a conventional decoration, specifically an embossing pattern. If necessary, such as for example in customs controls, the identification mark however can be easily exposed by depression so that analysis of the packaged product with respect to originality can take place.

Abstract: The invention specifies a blister pack (1) with a radio-frequency identification device (2, 2?) which comprises—a support body (3) which is made of flat plastic material and which has a plurality of depressions (5), produced from deforming this material, within a planar region (4) for the purpose of holding the packed goods,—an aluminium sealing foil (7) which is connected flat to the planar region (4) of the support body (3), and—a radio-frequency identification device (2, 2?) which is fitted in the region (8) of the support body (3) which projects over the aluminium sealing foil (7).

Abstract: The present invention pertains to a packaging element comprising a supporting material fitted, on its face turned opposite the package, with a layer presenting a marking area and, on its face turned to the package, with a rough surface coating. The coating roughness has a depth of 1 to 100 &mgr;m, which can be obtained by using granulous filling material. The rough surface packaging element is suited as a covering element, including for yoghurt, as well as in the production of labels for bottle finishes.

Abstract: The description relates to vinyl alcohol copolymers which can be produced by the acid-catalysed acetalisation reaction of polyvinyl alcohols with a degree of saponification of 80-99.5 mol % and preferably between 88 and 99.5 mol % with natural substances or their derivatives containing carbonyl or presumptive carbonyl groups. The description also relates to water-soluble films containing such vinyl alcohol copolymers, the solubility of which can be adjusted to the desired solution temperature. Said water-soluble films are used as packaging materials and auxiliaries, e.g. in the form of sealing lacquers.

Abstract: A piece of goods to be packaged is wrapped in a wrapping sheet of flexible packaging material made of two different layers or laminated composite materials. Two overlapping marginal areas of the packaging material are sealed or glued together to form the bottom of the package. The layer or laminated composite material that faces the packaged goods within the top marginal area of packaging material has one or several cut-outs, through which both overlapping marginal areas of packaging material are interconnected.

Abstract: In a package, especially a pouch package, with a covering made of a flat foldable packaging material in which the inner sides of two strip-like edge regions are sealed together in a joining region to form the covering, there is a strip-like tear region in the package covering which starts from one of the two strip-like edge regions, extends substantially prependicularly thereto and has notches or linear punched-out regions only within the strip-like edge region. Here, at the beginning of the rear region between the two strip-like edge regions, there is a tab of flat material which is firmly secured to the edge region from which the tear region starts and is secured detachably or not at all to the other edge region, while the remainder of the flat of the tab projects beyond the edge of the edge region.

Abstract: A tubular pouch is provided with a tear-open strip which begins at a U-shaped perforation formed in one of two edge strips of the pouch which are joined across a junction area by cold-sealing into tubular pouch fins. The U-shaped perforation defines a grip formed by the wrapping material inside it and includes legs extending toward and entering the junction area. However, in its remaining portion, the U-shaped perforation does not reach as far as the junction area and thereby manufacturing tolerances relating to the U-shaped perforation and the relief cold bondings as well as lateral shifts between the two edge strips cannot result in bonding of the grip. When the grip is pulled to open the wrap, the wrapping material tears from the ends of the perforation along approximately parallel lines. The grip can be advantageously folded over 180.degree. in order to be readily grasped.

Abstract: The invention concerns a tube-pouch wrap comprising a fin 2 within which two strip edges 3 of the wrapping material are joined together at their inner sides by a peelable cold seal, the junction area including one sub-section 4 at each end of the two edge strips 3 and an unsealed middle zone 5 being present between said subsections. An adhesive label 6 is folded about the fin edge 8 to connect the two edge strips 3 of the fin to close the wrap hermetically and to serve as an opening accessory, said adhesive label covering the middle zone 5 and overlapping the two sub-sections of the fin 2 by bonding to the fin surface. At one side of the fin, the adhesive label 6 comprises a strip edge 11 forming a grip 12 unbonded to the fin surface. Advantageously the fin 2 is so folded on the wrap envelope 13 and bonded to it that the grip 12 is uppermost.

Abstract: The invention concerns an essentially hermetic wrapping, in particular a tubular pouch wrapping, comprising two strip-like edge zones of the wrap material that are joined together by sealing, and two incisions 4, 18, 24, 28 are present in at least one of the two said edge zones, the wrap material forming a grip tab between said two incisions by means of which a tear-open region is pulled off when the wrapping is being opened.
