摘要:
A biaxially oriented laminate film including a core layer including a blend of crystalline polylactic acid polymer and an inorganic antiblock particle which is biaxially oriented at low transverse direction orientation temperatures to impart a degree of cavitation around the particles such that a matte or opaque appearance is obtained. The laminate film may further have additional layers such as a heat sealable layer disposed on one side of the core layer including an amorphous polylactic acid resin and/or a polylactic acid resin-containing layer disposed on the side of the core layer opposite the heat sealable layer, a metal layer, or combinations thereof.
摘要(中):
一种双轴取向层合膜,其包括芯层,其包含结晶聚乳酸聚合物和无机防粘剂颗粒的混合物,其在低横向取向温度下双轴取向以在颗粒周围赋予空穴化程度,从而获得无光泽或不透明的外观 。 层压膜可以进一步具有附加层,例如设置在芯层的一侧上的可热封层,包括无定形聚乳酸树脂和/或设置在芯层的与可热封的相反侧的聚乳酸树脂含有层 层,金属层或其组合。
