    摘要： This invention relates to a biaxially oriented polypropylene (BOPP) film comprising a polyolefin-containing base layer with at least 1 weight percent recycled polyolefin material comprises polyhydroxy amino ether polymer (PHAE) and an amount of compatibilizing agent such that the laminate film has a gel count of less than 15 gels/80 in2. The laminate film could have an optional tie-layer which could comprise PHAE adhered to one side; the polypropylene film contains an amount of reprocessed PHAE-containing film and a compatibilizing agent to reduce significantly or eliminate visual defects such as gels, voids, etc. The use of the compatibilizing agent with the reprocessed PHAE also aids in improving subsequent biaxial film orientation and maintains film properties. The film of the embodiments of the invention has excellent appearance and aesthetic properties and can be suitable for transparent, white opaque, or metallized film applications depending on formulation.

    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.
