Abstract: A film composite including a first external layer and a second external layer, a first middle layer between the first and the second external layer, wherein the first and/or second external layer comprise components which comprise at least a polyolefin, a component selected from the group consisting of microbeads, polystyrene, and high-molecular-weight polyethylene, and a polymer having a melting point lower than that of other components of the first and/or second external layer.

Abstract: A multi-layer film comprising a layer (a) and a layer (c), each layer comprising at least one propylene copolymer in a quantity of at least 30% by weight and at least one propylene homopolymer in a quantity of at least 20% by weight, in each case relative to the total quantity of the layer (a) or (c), at least one inner layer (b) based on at least one homo- and/or co-polyamide having isophorondiamine units as polyamide components, and further comprising adhesion promoter layers (d) and (e) arranged between the layers (a) and (b) and between the layers (b) and (c), respectively, each adhesion promoting layer being based on at least one modified thermoplastic olefin homopolymer or olefin copolymer; a sealing sheet comprising such a multi-layer film, and the use of such a multi-layer film for covering roofs.

Abstract: A packaging bag includes two long sides, two narrow sides, a top side or roof surface, a bottom side produced from one or more layers of plastics material foils, and a carrying handle including a single-part or multi-part plastics material strip arranged to pass around the packaging bag in a region of the top side.

Abstract: Plastic sheeting with a rough surface to increase the coefficient of friction, whereby at least one side of the sheeting is equipped with a layer (2, 22, 32), which layer contains the rough surface. This surface can be produced either by the coextrusion process or the coating method, and may also be provided on both sides.

Abstract: Film arrangement (1) having at least one film layer, wherein the film arrangement is produced at least from one film layer (3) made of a biodegradable PLA and a long-chain plasticizer.

Abstract: The invention relates to a method for producing a multilayer coextrudate, comprising a plastic layer that has release properties vis-vis adhesives, the release-property producing materials being disposed in the plastic layer. When the coextrudate is produced, a first web(support web I) is provided on the one side of which an adhesive layer is disposed, followed by the plastic layer having the release properties, which in turn is linked with a second web (support web II). The release layer does not show substantial migration with respect to the adhesive and the release effect does not substantially change afterwards, especially during storage.

Abstract: Film-bitumen combination with at least three layers is used in particular as a membrane to cover roof areas. At least two film layers of the combination are made from different materials.

Abstract: A film combination or multilayer film with at least two layers is provided for particular use as a release film for membranes that contain oil. At least two film layers are made from different materials.

Abstract: The invention relates to a method for packaging objects (4, 154, 164, 174, 184) which are at least partially self-adhesive by means of a packaging material (1, 30, 95, 151). Said packaging material segmentally comprises an anti-adhesive arrangement (2, 33, 93, 103, 124, 152, 162, 172, 175, 176, 182, 192), whereby the objects (4, 154, 164, 174, 184) are laid on the packing material with their self-adhesive section on the section of the packing material with an anti-adhesive arrangement (1, 30, 95, 151) and the objects (4, 154, 164, 174, 184) are finally covered by packing material (1, 30, 9, 151).

Abstract: Process for bonding several layers of plastic film, particularly plastic bags, into a block, where it is supposed to be possible to remove the plastic films or plastic bags from the block individually; the plastic films or plastic bags are bonded together in an edge strip by means of ultrasonic welding.
