ABSTRACT:
The present invention provides unified multilayer films having at least one internal layer that includes a pressure sensitive adhesive material. Preferably, multilayer films of the present invention are no greater than about 250 micrometers (.mu.m) thick. In particularly preferred embodiments of the present invention, multilayer films include layers that include a pressure sensitive adhesive material alternating with layers that include a material that is not a pressure sensitive adhesive. In other preferred embodiments, multilayer films include alternating layers of different pressure sensitive adhesive materials.
