Abstract
A multi-microlayer thermoplastic film structure and methods of making the same. More specifically, this invention relates to a multi-microlayer film having a degradable polymer layer and a thermoplastic elastomer layer. Filler materials may be included in either the degradable polymer layer or the thermoplastic elastomer layer. The multi-microlayer films may be formed in a co-extrusion process.
Claims31
