    摘要： A coextruded multilayer film, having of at least a high crystalline propylene homopolymer resin layer of isotactic content greater than about 95%; a discharge-treated surface on one side of said polyolefin resin layer; an amount of hydrocarbon resin up to 10% by weight of the high crystalline propylene homopolymer of greater than about 95% isotactic content; and on the high crystalline propylene homopolymer resin layer side opposite said discharge-treated surface, a heat sealable layer or winding layer having an antiblock is disclosed.

    摘要： A release film for label stock and the like having:(a) a cavitated layer of a thermoplastic polymer matrix material within which is located a strata of voids, positioned at least substantially within at least a substantial number of each of the voids is at least one spherical void-initiating solid particle which is phase-distinct and incompatible with the matrix material, the void space occupied by the particle being substantially less than the volume of the void, with one generally cross-sectional dimension of the particle at least approximating a corresponding cross-sectional dimension of the void; the population of the voids being such as to cause a degree of opacity of less than 70% light transmission;at least one surface of the layer free of any coating tending to mask the surface affects of cavitation; and(b) opposite to this surface, a coating of a release material of a type having a tendency to partially transfer to any contacting surface.
