An opaque, biaxially oriented film structure is described which comprises:

Opaque film composites and method of preparing same

The film resulting from and the process for forming a firmly bonded film laminate combination comprising, preparing an intimate combination I of polypropylene and a maleic acid anhydride modified olefin polymer; forming a film of at least one layer of said combination I with at least one layer of a polymer II selected from the group consisting of polyvinyl alcohol and an ethylene-vinyl alcohol copolymer; and effecting adhesion between the layers by orienting the film.

Polypropylene barrier film and method of forming same

An opaque oriented non-thermoplastic polymer film containing opacifying voids which opacifying voids contain rigid microspheres therein. The method of preparing such an opaque oriented non-thermoplastic film by incorporating rigid microspheres within the non-thermoplastic polymer forming a film thereof and orienting the same to create opacifying voids therein.

Opaque oriented non-thermoplastic polymer film and method of forming same

Method and system for orienting a multilayer polymeric film structure by differentially heating the films so that orientation at their respective optimal temperatures is achieved.

Process and system for orienting layered polymer films

A method and system are disclosed for orienting a multilayer polymeric film structure by differentially heating different film layers thereof by dielectric heating and then molecular orienting the film layers at their respective optimal orientation temperatures.

System and process for simultaneously orienting the films of a film

An ink receptive synthetic film structure formed by delaminating the void containing a matrix material and the method of preparing the same.

Synthetic film with a paper-like surface and method of forming same

The present invention is directed to an opaque, biaxially oriented polymeric film structure of lustrous satin appearance comprising a thermoplastic core matrix having a strata of voids; said voids being created by the inclusion within the matrix material of spherical void-initiating solid particles which are incompatible with the matrix material. The void space occupied by the particle is substantially less than the volume of the void. The polymer matrix material is extruded in the form of a film and positioned on opposite surfaces of the film are void free, transparent thermoplastic skin layers adhering to said surfaces. The structure has excellent opacity and extremely high gloss measurement and a lustrous satin appearance.
