Multilayer films having pressure sensitive adhesive layers

摘要

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.
