    摘要： An opaque, biaxially oriented polymeric film structure, produced by orienting the film to a degree which provides low light transmission and improved machinability. The film structure includes a thermoplastic polymer matrix core layer having a first surface and a second surface, within which is located a strata of voids; positioned at least substantially within a substantial number of the voids is at least one spherical void-initiating 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; the population of the voids in the core being such as to cause a significant degree of opacity, the core layer including a light absorbing pigment of lamellar morphology; a first non-voided thermoplastic polymer intermediate layer having a first surface and a second surface, the second surface of the first intermediate layer adhering to the first surface of the core layer; and a second non-voided thermoplastic polymer intermediate layer having a first surface and a second surface, the second surface of the second intermediate layer adhering to the second surface of the core layer; wherein the level of light transmission of the film is less than 10% and the degree of orientation is about 8 TDO by less than about 5 MDO.

    摘要： A multilayer opaque, biaxially oriented polymeric film structure. The film structure includes (a) a thermoplastic polymer matrix core layer having a first surface and a second surface, within which is located a strata of voids; positioned at least substantially within a substantial number of the voids is at least one spherical void-initiating 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 in the core being such as to cause a significant degree of opacity; (b) at least one thermoplastic polymer intermediate layer having a first surface and a second surface, the second surface of the intermediate layer adhering to at least the first surface of the core layer, the intermediate layer including up to about 12% by weight of titanium dioxide contact pigment; and (c) a titanium dioxide-free, non-voided thermoplastic skin layer adhering to the first surface of the intermediate layer, the void-free skin layer and the intermediate layer together being of a thickness such that the outer surface of the skin core layer does not, at least substantially, manifest the surface irregularities of the matrix core layer.

    摘要： An opaque, biaxially oriented multi-layer polymeric film structure of reduced surface coefficient of friction. The film structure, includes: (a) a thermoplastic polymer matrix core layer having a first surface and a second surface, within which is located a strata of voids; positioned-at least substantially within a substantial number of the voids is at least one spherical void-initiating 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; the population of the voids in the core being such as to cause a significant degree of opacity; (b) at least one thermoplastic polymer intermediate layer having a first surface and a second surface, the second surface of the intermediate layer adhering to at least the first surface of the core layer, the intermediate layer formed from a mixture comprising the thermoplastic polymer, a migratory slip agent and a migratory antistatic agent; and (c) a non-voided thermoplastic skin layer adhering to the first surface of the intermediate layer; wherein the slip agent and the antistatic agent migrate to the outer surface of the skin layer and are effective to reduce the surface coefficient of friction thereof.
