An elastic composite strip has a longitudinally elongated substrate strip having a pair of opposite faces and formed of an elastomer that is highly stretchable longitudinally but only limitedly or not stretchy at all transversely. A respective soft knit fabric cover strip that is highly stretchable longitudinally but only limitedly or not stretchy at all transversely extends longitudinally on each of the faces. Respective arrays of longitudinally spaced and transversely extending lines of adhesive are bonded to the faces and to filaments of the respective cover strips.

A laminate material element for a hook-and-loop closure, particularly for a diaper closure, having a carrier and a textile material laminated onto the carrier, which material has a basic structure formed from threads, and additional threads incorporated into the basic structure by means of knitting. The additional threads incorporated into the basic structure by means of knitting form loops provided for making a connection with hook-and-loop hooks. At least a part of the threads or fibers of the basic structure is formed from polyamide. According to the invention, the additional threads incorporated into the basic structure by means of knitting have polyolefin, particularly polypropylene, as their main component.

A laminate material web has two webs of nonwoven fabric that lie on the outside, and film strips of an elastic film disposed between them, in sections, whereby the nonwoven fabric webs are connected with one another in the regions between the film strips. The film strips are connected with the inner surfaces of the nonwoven fabric webs only at the two longitudinal edges, in each instance, both on the top and on the bottom, and the nonwoven fabric webs have weakenings running in the web direction, in the regions that cover the film strips. A method for the production of a laminate material web is also described.

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. When the action of pressure is released, preferably the bottom web film performs its resetting process and encloses the product thereby at least in part in such a manner that unwanted air inclusions are removed and also a certain product compaction occurs. Then, sealing between top and bottom web films is performed.
摘要:
An elastomer laminate has an elastomer carrier layer composed of a thermoplastic elastomer, and at least one microtextured cover layer composed of a polymer that has a lower elasticity than the material of the carrier layer. The microtexture is produced by stretching the laminate beyond the elasticity limit of the cover layer and elastic recovery of the stretched laminate. The microtextured cover layer contains a plurality of pores.

A method for the production of an elastic composite material with a textile surface. First, a laminate is produced, which has elastic cover layers and a core composed of a nonwoven fabric. Subsequently, the laminate is separated into two strips, each of which has a cover layer and an adhering layer of nonwoven fabric, by tearing open the core.

A body in the form of a packaging or of a molded part has an outer layer composed of a film, on which a radio-frequency identification (RFID) arrangement is provided. An antenna of the RFID arrangement is printed directly on a layer of the film, wherein an RFID chip of the RFID arrangement is disposed on a support section, and wherein the support section with the RFID chip is set onto the film in the region of the RFID antenna.
摘要:
A film laminate wound up to form a film roll, from which bags with an integrated handle are produced in a VFFS form-fill and seal bag machine. The film laminate is produced by coating a film web of an outer film with a lamination adhesive and applying a material web of a sealable film to the adhesive layer. The material web is pressed together with the film web and adhesive layer in a lamination gap between a lamination roller and a pressing roller. A reinforcement strip passed to the lamination gap contacts the adhesive layer, between the film web and the sealable film. The circumference surface of the pressing roller has a depression that is coordinated with the film thickness and the film width of the reinforcement strip, so that a uniform pressing pressure prevails in the lamination gap, over the entire width of the laminate.
摘要:
A laminate usable as a diaper closure has a pair of generally contiguous outer fleece layers having longitudinally extending and parallel outer edges and a core layer of foil of LP or LLP polyethylene extending between the outer layers substantially a full width of the outer layers between the edges. The foil has a thickness between 5 μm and 20 μm. Bonds are provided between the core layer and each of the outer layers. The laminate has regions activated by stretching and in which the laminate is semielastric, and unactivated regions in which the laminate is not stretchy.

An elastic film, particularly for hygiene articles, has at least one layer that is produced extrusion of an elastomer polymer composition and subsequently cross-linked. The elastomer polymer composition contains a mixture of 40 to 90 parts by weight of a styrene block copolymer, 5 to 50 parts by weight of a plasticizer oil, and up to 10 parts by weight of a thermoplastic polymer. The layer of the elastomer polymer composition is cross-linked by treatment with electron beams. The elastomer polymer composition additionally contains 2 to 20 parts by weight of a reactive plasticizer that has a mole mass of less than 10,000 kg/kmol, is compatible with soft segments of the styrene block copolymer, and has functional acrylate groups.
