Abstract: The packaging composite film has an outside and an inside. It also includes a cover layer facing the outside, an inner layer, which faces the inside and has a lower puncture and tear resistance than the cover layer, and a liquid-soluble intermediate layer arranged between the cover layer and the inner layer. To transport liquid from the outside to the liquid-soluble intermediate layer, liquid-transporting openings are provided, which completely penetrate the cover layer and extend in the direction of the inside at least to the intermediate layer, without including the inner layer. A childproof packaging, which is nevertheless easy to open and therefore senior-friendly, can be realized by means of the packaging composite film.

Abstract: The invention relates to a thermoformable multilayer foil encompassing at least one polyolefin layer based on a thermoplastic polyolefin, olefin copolymer, or mixture of these, and at least one gas-barrier layer, where the oxygen transmission of the multilayer foil is at most 0.5 cm3 m?2 d?1 bar?1.

Abstract: At least one surface of the film laminate with at least one diffusion-barrier layer for production of a vacuum insulation panel has a heat-sealable layer, which comprises at least one sublayer of an additional diffusion-barrier layer composed of polyvinyl alcohol, in particular ethylene-vinyl alcohol copolymer (EVOH) within a multi-layer, preferably jointly extruded composite of the sealable-layer sublayers. The level of gas- and water-vapor-barrier effect provided by the high-barrier laminate can be significantly further increased, by a factor of about 2, by virtue of the additional diffusion-barrier layer integrated into the sealable layer.

Abstract: A film laminate with at least one diffusion-barrier layer for production of a vacuum insulation panel, which can be used in the construction sector, has on at least one surface a heat-sealable polyolefin layer. Within this layer or on an external individual film or within a co-extruded composite that comprises at least externally a polyolefin layer, the polyolefin is provided with an effective amount of a flame retardant or of a mixture of flame retardants. This film laminate permits production of vacuum insulation panels which can be used in the construction sector, because when tested to DIN 4102-1 they meet the specifications for construction class B2.
