Abstract: Carrier films, adhesive tapes including the carrier film, hand tearable carton sealing tapes, and methods of making the same are described. The carrier films include a first layer of a polyethylene, and a second layer of a polypropylene coextruded therewith and biaxially oriented therewith. This carrier film has a first major surface and a second major surface. A pressure sensitive adhesive may be disposed on the first major surface of the carrier film to make an adhesive tape. The first major surface may be defined by the layer of polypropylene.

Abstract: The present invention provides colored iridescent film comprising a core of substantially parallel layers wherein alternate of the layers comprise a first polymer and the remaining layers comprise a second polymer and at least one of the layers contains organic pigment. The present colored iridescent film may advantageously be used in decorative applications such as glitter.

Abstract: The present invention provides a film comprising a plurality of contiguous layers that are substantially parallel to each other wherein at least every other of the layers is made of polylactide. The present iridescent film may be used in flexible and rigid decorative packaging.

Abstract: An optical effect thermoplastic resinous laminate film of very thin layers, a substantially uniform thickness, and being generally parallel, and wherein the contiguous adjacent layers differ in refractive index. The film containing an interior layer being parallel to the contiguous adjacent layers but being different from the contiguous adjacent layers so as to provide a change in the optical or physical properties of the film.
