摘要: The present invention relates to a matte surface film comprising: (a) a base layer comprising a polyolefin; and (b) a matte surface layer comprising a blend of a non-hydrocarbon polymer with at least one incompatible polyolefin, wherein said non-hydrocarbon polymer includes monomeric units with polar functional groups. The film may be used for packaging and label applications.

摘要: A film structure comprises a first sealable skin layer (a) of an olefin co- or terpolymer having an external surface which contains a slip/antiblock system. The slip/antiblock system comprises non-migratory particulate crosslinked hydrocarbyl substituted polysiloxane and silica antiblock particles. Layer (a) is located on one side of a core olefinic polymer layer (b). On an opposite side of the core layer (b) there is a second skin layer (c) which is ethylene homopolymer and which is free of the slip/antiblock system, optionally the second skin layer (c) is metallized.

摘要: A film structure comprises a first outer skin layer (a) of an olefin co- or terpolymer having an external surface which is sealable and machinable, the first skin layer containing a non-migratory particulate crosslinked hydrocarbyl substituted polysiloxane, and which is located on one side of a core olefinic polymer layer (b) on an opposite side of the core layer there is a second skin layer (c) which is ethylene homopolymer and which is free of the particulate crosslinked hydrocarbyl-substituted polysiloxane of the first skin layer, the second skin layer. In one embodiment, for improved barrier properties, the ratio of particle size to thickness of the (a) skin layer ranges from about 1.25 to about 2.5.
