    摘要: The present invention relates to a matte surface film comprising: (a) a base layer comprising high density polyethylene (HDPE); and (b) a matte surface layer comprising a blend of two or more incompatible polyolefins. In preferred embodiments, the matte surface layer comprises (i) a propylene homopolymer or propylene interpolymer and (ii) an ethylene homopolymer or ethylene interpolymer. The film possesses easy and improved cuttability and may be used for packaging and label applications.

    摘要: High density polyethylene (HDPE) films, preferably containing blends of HDPE resins or microcrystalline wax, are oriented up to about two times in the machine direction and six times or more in the transverse direction to give films having good dead-fold and water vapor transmission characteristics making them highly suited for packaging, particularly for dry foods when coated with or coextruded with a heat sealable layer, e.g. Surlyn.

    摘要: Disclosed is a multi-layer film comprised of at least one high density polyolefin (HDPE) layer, at least one polyamide layer and an HDPE/polyamide adhesion promoting agent. The agent is substantially free of inorganic salt groups and it is a non-ionic product of a polymerization reaction of a C.sub.2 -C.sub.6 alpha-olefin with a monocarboxylic acid of the formulaR--COOHwherein R is an ethylenically unsaturated hydrocarbyl group.
