    摘要： A skin layer of a thermoplastic polymer includes an additive to promote metal adhesion to the surface of this layer. This additive is one or more compounds of the formula, R-X, where R is an aliphatic hydrocarbyl group having an average of from 20 to 200 carbon atoms and X is a polar group, such as —COOH or —CH2OH. The film may be biaxially oriented and include a polypropylene core layer. The film may be metallized with an appropriate metal, such as aluminum. A heat sealable skin layer may be provided on the opposite side of the film from the metallizable skin layer.

    摘要： A uniaxially heat-shrinkable, biaxially oriented, multilayer film having a polypropylene-containing core layer comprising at least 70 wt. % of said multilayer film and optionally, at least one polyolefin-containing skin layer adjacent said core layer, is prepared by biaxially orienting a coextrudate and therefore orienting said coextrudate by stretching 10 to 40 % in the machine direction. The core layer contains isotactic polypropylene and a sufficient amount of syndiotactic polypropylene to inhibit uniaxial heat shrinkage at temperature below about 50.degree. C. The skin layer can be selected from the group consisting of polypropylene, ethylene-propylene copolymer, polyethylene, and ethylene-propylene-butylene terpolymer.

    摘要： A uniaxially heat-shrinkable, biaxially oriented, multilayer film having a polypropylene-containing core layer containing at least 70 wt. % of the multilayer film and at least one polyolefin-containing skin layer adjacent the core layer is prepared by biaxially orienting a coextrudate and thereafter orienting the coextrudate by stretching 10 to 40% in the machine direction. The core layer contains isotactic polypropylene, a modifier which reduces the crystallinity of the polypropylene-containing core layer and a nucleating agent. Such modifiers include atactic polypropylene, syndiotactic polypropylene, ethylene-propylene copolymer, propylene-butene-1 copolymer, ethylene-propylene-butene-1 terpolymer, and linear low density polyethylene. The nucleating agent improves long term dimensional stability. The skin layer can be high density polyethylene on both sides or high density polyethylene on one side and isotactic polypropylene on the other side.

    摘要： A process for making an opaque, oriented polymeric film structure and the resultant film structures. The process comprises preparing a melt containing a crystallizable polymeric matrix material at a temperature of at least above the melting point of the polymeric matrix material and thereafter forming the melt into a sheet containing molten polymeric matrix material. The sheet containing molten material is then cooled to form a sheet containing amorphous polymeric matrix material and crystallites of the polymeric matrix material. The sheet while containing the amorphous polymeric matrix material is then formed into a film by stretching the sheet in at least one direction so as to form voids adjacent to at least some of the crystallites and thereby impart opacity to the film. Film structures made by the above process have a plurality of voids, at least some of the voids not containing a void-initiating particle and at least some of the voids being interconnected with an adjacent void in the polymeric matrix material, the number of voids being sufficient to impart a significant degree of opacity in the film structure.
