BIAXIALLY ORIENTED POLYLACTIC ACID FILM WITH HIGH BARRIER
摘要
<p>A metallized laminate film exhibiting improved moisture barrier property as well as maintaining a high bio-polymer content and degradability property is disclosed. The laminate film includes a first core layer of polylactic acid polymer and a second skin layer comprising a polyolefin metal receiving layer. The metal receiving layer or the core layer, or both, may be blended with an amount of polar- modified tie-resin to improve bonding. Alternatively, a discrete tie-resin layer may be interposed between the polyolefin metal receiving layer and the crystalline polylactic acid polymer core layer. The polyolefin metal receiving layer may be discharge- treated on the side opposite the core layer and metallized.</p>
