20100025888 | METHOD OF MAKING A BACK-MOLDED PLASTIC PART - A molded part is made by cold-stretching a nonwoven web so as to rupture fibers or filaments thereof, laminating to a face of the cold-stretched nonwoven web a stretchable plastic film, and then inserting the laminated nonwoven web and film into a mold cavity with the film juxtaposed with an inner surface of the cavity and the cold-stretched web turned inward. This mold cavity is then filled a polymer melt to press the film against the inner mold surface while forcing the melt to penetrate the nonwoven web. | 02-04-2010 |
20110189437 | METHOD OF MAKING A THERMOPLASTIC FILM WITH A THREE-DIMENSIONALLY STRUCTURED SURFACE - A thermoplastic film with a three-dimensionally structured outer surface is made by coextruding through a slit nozzle a multilayer molten plastic film having an outer layer formed of a thermoplastic polyurethane elastomer with an isocyanate additive and an inner layer. This multilayer film is compressed in a nip between a roll and a belt to emboss a three-dimensional structure into the outer layer. The roll is cooled to cool the film and set the three-dimensional structure in the outer surface of the outer layer. | 08-04-2011 |
20120037300 | DIAPER CLOSURE AND METHOD OF MAKING SAME - A laminated web from which diaper closure elements may be punched is made by first applying at least two pairs longitudinally extending and transversely spaced bend-resistant strips to a first longitudinally extending nonwoven tape. Then a respective longitudinally extending strip of an elastically stretchable polymer is applied to the first nonwoven tape between each of the pairs of the bend-resistant strips with the polymer strip partially overlapping both of the bend-resistant strips of the respective pair. A second longitudinally extending nonwoven tape that covers and extends transversely to both sides of the polymer strip is applied over the bend-resistant strips and the polymer strips to form a laminate with the polymer strip between the first and second nonwoven tapes. | 02-16-2012 |
20120189830 | LABEL FILM - A label film is formed by means of extrusion and has a layer that forms the surface, on a first side, composed of polyethylene with a proportion of at least 70 wt.-%, preferably at least 85 wt.-% high-density polyethylene, wherein the film thickness amounts to less than 75 μm. According to the invention, the 60° reflectometer value on at least the first side of the label film, determined according to DIN 67 530, is greater than 80, preferably greater than 90. | 07-26-2012 |
20130133294 | METHOD FOR THE PREFERABLY CONTINUOUS PACKAGING OF PRODUCTS - 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. | 05-30-2013 |
20130248411 | FOOD-PACKAGING TRAY AND METHOD OF MAKING SAME - 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. | 09-26-2013 |
20140079938 | PLASTIC FILM - A plastic film having a thickness of less than 400 μm has a base layer at least partially of polyolefin of renewable raw material or a polyolefin mixture of renewable raw material and a first layer foamed by at least 20%. | 03-20-2014 |
20140116566 | PIPE LINER AND METHOD OF RELINING A SEWER PIPE - A pipe liner has a tubular base of a thermoplastic elastomer or ionomer saturated with a curable resin, and a tubular inner film inside the tubular base itself. The inner film is formed by a core layer of a thermoplastic elastomer or ionomer and two polyamide outer layers. | 05-01-2014 |
20140322530 | MULTILAYER COEXTRUDED FILM, IN PARTICULAR PACKAGING FILM - The invention relates to a multilayer film produced by coextrusion, more particularly packaging film, having a core layer comprising a core layer mixture, a seal layer comprising a seal layer mixture, and a print layer comprising a print layer mixture. The core layer is disposed between the seal layer and the print layer, and in accordance with the invention comprises at least one polyolefin and starch, preferably thermoplastic starch. The seal layer mixture and the print layer mixture comprise in each case at least one polyolefin and in each case starch, preferably thermoplastic starch. | 10-30-2014 |
