The present invention relates to a multilayer film comprising a layer (a) and a layer (c), in each case based on at least one propylene copolymer in an amount of at least 15% by weight, at least one propylene polymer in an amount of at least 40% by weight, in each case based on the total weight of the layer (a)/(c), at least one multi-ply inner layer (b) based on at least one homo- and/or copolyamide comprising isophoronediamine units as a polyamide component, adhesion promoter layers (d) and (e), wherein the thickness of the multi-ply layer (b) is at least 40% of the total thickness of the multilayer film, preferably at least 45% or at least 50%.

Multilayer film having high tear strength

A packaging film suitable for an outer packaging composed of an optionally release-capable, upstretched, at least monolaminar polyolefin film comprising a) a layer (a) based on a mixture of &#x3b1;) 20-49% by weight of a polypropylene or of at least one propylene copolymer, or combination thereof, and of &#x3b2;) 80-51% by weight of at least one polyethylene or ethylene copolymer, and optionally &#x3b3;) customary auxiliaries, with a layer thickness of &#x2264;20 &#x3bc;m, on at least one surface of the layer (a) a release coating (b) composed of cured polysiloxane, wherein the tensile strength of the polyolefin film in machine direction is at least 6.5 N/cm, measured according to DIN EN ISO 527-3, and outer packagings produced therefrom.

Packaging film

Hydrophobic breathable film based on a polymer mixture of A) at least one hydrophilic elastomer block copolymer made of at least one polyamide block and at least one polyalkylene oxide block and B) at least one thermoplastic polymer, which regulates the steam-permeability of the breathable film.

Film with adjustable water vapor-permeability

A precursor composite material () is provided, having a layer sequence () comprising an adhesive layer (), a carrier layer () on the adhesive layer (), a release layer () on the carrier layer () and a parting layer () on the release layer (), wherein the layer sequence () is arranged in such a way that the side of the adhesive layer () facing away from the layer sequence () is arranged at least in sub-regions on the side of the parting layer () facing away from the layer sequence (). Further provided are a composite material, a method for producing the precursor composite material, a method for producing the composite material and a use of the precursor composite material and of the composite material.

Precursor composite material, method for producing a precursor composite material, method for producing a composite material and use of a precursor composite material and of a composite material

A wrapper that opens relatively quietly and wraps a sheetlike hygiene product provided on one side with an adhesive, said wrapper being based on a packaging material in web form and composed of a polymeric film comprising a) at least one heat-sealable layer based on a mixture of at least one Cor Colefin homopolymer or copolymer and not more than 30% by weight, based on the total weight of the layer a), of polybutylene and b) optionally a layer of polyethylene having a density of 0.88-0.94 g/cm; the layer a), at least in those sections which face the regions of the hygiene product that are provided with the adhesive, has a release coating, and otherwise, at least in the sub-regions which are joined to form edge closures in the form of stripes or lines, has no release coating.

Quiet-opening wrapper

The present invention relates to a predominantly biodegradable double-separating film and comprising at least one carrier layer (a) that is based on at least one biodegradable polymer, and at least one release layer (b) that is based on at least one cured polysiloxane. The curing of said release layer is based, at least partially, on at least one cross-linked monomer or oligomer additive. Said additive also promotes adhesion between the carrier layer (a) and the release layer (b), and has no siloxane groups but does have at least two functional groups, of which at least one is a functional group with at least one carbon double bond. No adhesion-promoting layer is present between the carrier layer (a) and the release layer (b). In addition the invention relates to the use of such a separating film as a removable protection and cover film.

Predominantly biodegradable release film

Multilayer film, comprising an at least flushable, thermoplastic layer composite made of at least one layer which is at least comminutable via exposure to water and is resistant to cold water or can only be dissolved slowly therein, formed of at least one at least partially saponified polyvinyl acetate having a layer thickness of &#x3c;10 &#x3bc;m, and at least one layer soluble in cold water comprised of at least one at least partially saponified polyvinyl acetate and at least one substance that increases the water solubility, selected from the group consisting of biodegradable polymers, surfactants, inorganic pigments and fillers, and flushable packages produced therefrom.
