Abstract: A coextrusion film has a core layer made of thermoplastic elastomer, and first and second outer layers sandwiching the core layer. The outer layers are each formed from a polymer having a lower elasticity than the thermoplastic elastomer of the core, each have a layer thickness of less than 15 ?m, each have a density of less than 0.800 g/cm3, and each have more than 500 gas-filled cells per 1 cubic millimeter of volume.

Abstract: A coextruded polyethylene blown film, particularly for packaging, has a thickness between 20 ?m and 250 ?m and is formed by a foamed, particle-containing core layer between a first unfoamed weldable outer layer and a second unfoamed outer layer. The core layer has a polyethylene or a polyethylene-based mixture as a polymer component having a melt mass-flow rate (MFR) per DIN ISO EN 1133 of greater than 5 g/10 min at 190° C. and 2.16 kg.

Abstract: A bag has front and back face panels formed of a body film and each having two generally parallel and normally vertical side edges bridging ends of respective upper and lower edges, respective longitudinal side welds fixing the side edges of the front panel to the side edges of the back panel, a separate piece of label film different from the body film, covering a mid portion of one of the face panels between the respective longitudinal edges, and spaced downward from the upper edge of the one face panel and upward from the lower edge of the one face panel, and structure at the longitudinal edges holding the piece of label film on the one face panel without surface bonding of the piece of label film to the one face panel between the respective longitudinal edges.

Abstract: A surface-protection film has a first outer face normally applied to an object, a first outer layer forming the first outer face and including titanium-dioxide particles and 0 wt.-% to 0.05 wt.-% carbon black, and a second outer face opposite the first outer face and having a brightness value L* of greater than 85 at a measurement angle of 10° and a CIE standard illumination D65.

Abstract: A plastic film laminate with a thickness between 20 ?m and 250 ?m has a foamed core layer, a first unfoamed outer layer with a thickness of less than 70 ?m, and a second unfoamed outer layer with a thickness of less than 70 ?m, and a matte surface with a reflectometer value according to DIN 67530 of less than 40 at a measurement angle of 85°. The reflectometer value determined in this way is below 30 and particularly between 10 and 25.

Abstract: In an antifungal protective film having at least one layer and an acidifying polymer and a disulfite the at least one film layer includes fluid-filled bubbles or cells that are created by foaming. The cells created by foaming during the extrusion enable the generated sulfur dioxide to collect inside this film layer, thereby being buffered and achieving a long-term action releasing the antifungal sulfur dioxide. The film can have a single foamed layer containing the polymer and disulfite or such a layer sandwiched between two outer layers having different properties, all produced by coextrusion.

Abstract: A tear-open packaging is formed by a pair of plastic film panels having inner faces joined together by a weld. One of the film panels is formed by a two- or three-layer coextrusion having a nonsticky foam core layer and a weldable inner layer that is secured by the weld directly to the inner face of the other film panel. The strength of the core layer and of the bond between the core layer and inner and outer layers are such that, when the two panels are pulled away from each other, the core layer or an interface between the core layer and the weldable inner layer will tear along the weld. If the weld does not extend directly to an edge of the film tear-open packaging, the weldable layer breaks on both sides of the weld.

Abstract: 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.

Abstract: A package is formed a closed bag made of a multilayer film and contents enclosed in the bag. The film is folded to form the bag and has flat film sides and outer edges that are reinforced by weld seams. The film of the bag has a density of 0.5 g/cm3 to 0.9 g/cm3, a printable outer layer forming an outside surface of the package, an inner seal layer made of a sealable polymer forming an inside surface of the package, and a foamed polymer core layer between the outer layer and the inner layer. The contents are a lumpy or granular bulk material.

Abstract: A plastic film having a thickness of less than 400 ?m 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%.

Abstract: A monoaxially elastic laminate film is provided with a core layer made of a thermoplastic elastomer and at least one skin layer co-extruded together with the core layer. The skin layer is made of a thermoplastic plastic with a molecular lattice that becomes brittle when it solidifies, so that the plastic stretches only slightly when a stretching force is applied, and breaks without any transition when a pre-determined tear force has been exceeded. After becoming brittle, the molecular lattice is irreversibly broken up by monoaxial stretching in the stretching direction, but is maintained perpendicular to the stretching direction, and thereby reinforces the film in the crosswise direction.
