MULIT-LAYER FILM
A multi-layer film for an electronic device display having a clear, material base sheet film with a first side used by a user that is scratch resistant; a clear adhesive layer formed on a second side of the material base sheet film; and a synthetic separator film, that has excellent linear directional tear properties, that is temporarily affixed to the adhesive layer so that it can be removed by the user.
Multi-phasic polymer blend for adhering an outer edge banding layer to a substrate
A multi-phasic polymer blend for energy activated edge banding adhesion to a substrate is described. While the blend may be used for adhering edge banding to straight substrates, the blend is preferred for adhering edge banding to contoured substrates. The outer, hard, structural layer of the edge banding is formed from a polypropylene component. The polypropylene component at least includes polypropylene and an optional energy adsorber. The inner adhesion layer of the edge banding is formed from a multi-phasic polymer blend that bonds the outer layer of the edge banding to the substrate. The multi-phasic polymer blend at least includes a polyamide component, a polyolefin component, and a modified polypropylene component. Both the outer and inner layers forming the edge banding may be tinted to conform or contrast with the color of the finished substrate.
