Composite Package 摘要:A layer of a biodegradable, compostable co-polyester is extrusion coated onto the surface of a bio-degradable compostable cellulose film to overcome the limitations of cellulose film as a packaging film for fresh produce and still retain the biodegradability, compostability and stiffness of the overall structure. Additionally, good bond strength between the cellulose film and the extruded co-polyester polymer is achieved by applying a thin coating of co-polyester to the surface of the cellulose film by means of a solvent or water based coating process. A biodegradable, compostable co-polyester polymer is extrusion coated onto an additional barrier layer to provide a significant barrier enhancement in high humidity environments beyond levels that would be reasonably predicted. 摘要(翻译):一种可生物降解的一个层,可堆肥的共-聚酯是挤压涂覆到所述的一种生物可降解可堆肥化的纤维素表面纤维素膜的膜,以克服所述限制为一个包装膜用于新鲜产生和仍保持所述生物降解性; compostability和所述的整体结构的刚度,另外,所述纤维素薄膜之间的良好的粘合强度和所述挤出的共聚酯聚合物的目的是通过施加一个薄的涂层的共-聚酯以所述表面的所述纤维素膜的装置一种溶剂或水基涂层的过程。一种可生物降解,可堆肥的共-聚酯聚合物被挤压涂覆到一附加阻隔层,以提供一个显著的高湿度环境中的阻隔增强超过水平,其将被合理地预测。 公开(公告)号:EP2141191B1 公开(公告)日:2014-01-15 申请号:EP08159463 申请日:2008-07-01 申请人:Amcor Flexibles Transpac N V
