  • Publication number: 20170135874
    Abstract: A multilayer wrapper film for a hygiene product has a first outer layer, a second outer layer, and a pressure-sensitive adhesive layer between the first outer layer and the second outer layer and forming therewith respective adhesive bonds. The adhesive bond between the pressure-sensitive adhesive layer and the first outer layer is stronger than the adhesive bond between the pressure-sensitive adhesive layer and the second outer layer. An overall thickness of the first and second outer layers with the pressure-sensitive adhesive layer arranged therebetween is between 20 ?m and 80 ?m.

  • Publication number: 20130248411
    Abstract: A tray package for food has a stiff tray having a rim and formed inward of the rim with at least one throughgoing hole and a cover film fixed to the rim. A lining made of a flexible film is fixed to the rim between the tray and the cover film and forms with the cover film a closed compartment adapted to hold the food and with the tray an outer compartment that is open to the exterior through the hole.

  • Publication number: 20130133294
    Abstract: The invention relates to a method for the preferably continuous packaging of products, in particular foods, with or without an already stabilized inherent shape such as fresh meat, meat products and sausage products, sausage meat emulsion or similar products by encasing them on all sides with single-layer or multilayer films that can be fed from the web. According to the invention flexible films that can be deformed without the action of heating and are self-resetting, are used as bottom web films, wherein the bottom web films are temporarily deformed by the action of pressure in order to form troughs for receiving product. The respective product is introduced as portions into the trough and fixed there, wherein it is fixed by a top web film or covering film, optionally supported by a restrainer.

  • Publication number: 20130082422
    Abstract: A molded article is made by first providing a starting material comprised of a support web and a layer of expandable polymer particles on the support web. This starting material is fitted as several layers into a generally closed cavity of a mold or shaping shell so as to only partially fill the cavity. Then energy, for instance microwave radiation, is applied to the starting material in the cavity so as to expand or foam the polymer particles such that the starting material generally fills the cavity.

  • Patent number: 8272511
    Abstract: An article of commerce includes a disposable cleaning article and a package. The package exhibits soft visual and sound characteristics. The package is formed as a multilayer packaging film including at least a co-extruded vapor barrier film layer and a polymeric film layer having a melting point at least about 20° C. less than the co-extruded film layer. The polymeric film layer is sealable to form the package so as to enclose the disposable cleaning article, thereby to substantially retain the water content of the disposable cleaning article. The polymeric film layer further exhibits a corrected sound level of less than approximately 50 decibels at readily audible frequencies, such as 3-5 kHz. The reduced sound level may be achieved by providing a film with a high loss tangent. In addition, the multilayer packaging film may have an outer surface with a soft or “matte” appearance.

  • Patent number: 7601658
    Abstract: The invention relates to an elastic laminate. The laminate is made from a co-extruded elastic film, comprising an elastomeric support layer, at least one cover layer and at least one textile outer layer made from a non-woven. The cover layer has a low layer thickness by comparison with the support layer. The outer layer is laminated onto the cover layer. According to the invention, the cover layer is made from an elastomeric material, with essentially the same expansion properties as the material of the support layer and contains additives for modification of the surface properties.

  • Publication number: 20060113211
    Abstract: An article of commerce includes a disposable cleaning article and a package. The package exhibits soft visual and sound characteristics, which convey a desired quality to be associated with the enclosed cleaning article. The package is formed as a multilayer packaging film including at least a co-extruded vapor barrier film layer and a polymeric film layer having a melting point at least about 20° C. less than the co-extruded film layer laminated to the co-extruded film layer. The polymeric film layer is sealable to form the package so as to enclose the disposable cleaning article, thereby to substantially retain the water content of the disposable cleaning article.

  • Patent number: 7052750
    Abstract: A sealable film is used for the production of tear-open packages. The film, as a monofilm, in total, or as a multi-layer laminate film, produced by means of coextrusion, has at least in one layer a polymer mixture of a cycloolefin copolymer (COC) and polyolefin or an ethylene copolymer, whereby the COC portion in the polymer mixture is 10 to 80 wt.-%, the remainder polyolefin or ethylene copolymer. Packages produced from such films demonstrate balanced tear start and tear propagation properties in the crosswise and lengthwise direction of the film.

  • Patent number: 6783842
    Abstract: A multi-layer co-extruded film is particularly intended for use as a labeling, a laminating or a packaging film. The film includes two outer layers (1) consisting of a polyolefin, a polyolefin mixture or an olefin copolymer, and a core consisting of a mixture of styrene homopolymers and styrene-butadiene-styrene block copolymers at least in the areas bordering on the outer layers. The mixture contains more than 50% by weight up to a maximum of 90% by weight styrene homopolymer, the balance being styrene-butadiene-styrene block copolymer.
