    • This invention relates to a biaxially oriented polypropylene (BOPP) film comprising a polyolefin-containing base layer with at least 1 weight percent recycled polyolefin material comprises polyhydroxy amino ether polymer (PHAE) and an amount of compatibilizing agent such that the laminate film has a gel count of less than 15 gels/80 in2. The laminate film could have an optional tie-layer which could comprise PHAE adhered to one side; the polypropylene film contains an amount of reprocessed PHAE-containing film and a compatibilizing agent to reduce significantly or eliminate visual defects such as gels, voids, etc. The use of the compatibilizing agent with the reprocessed PHAE also aids in improving subsequent biaxial film orientation and maintains film properties. The film of the embodiments of the invention has excellent appearance and aesthetic properties and can be suitable for transparent, white opaque, or metallized film applications depending on formulation.
    • 本发明涉及一种双轴取向聚丙烯(BOPP)膜,其包含含有至少1重量%再循环聚烯烃材料的含聚烯烃的基层,包含多羟基氨基醚聚合物(PHAE)和一定量的相容剂,使得层压膜具有凝胶 小于15凝胶/ 80 in2。 层压膜可以具有可选的粘结层,其可以包含粘附到一侧的PHAE; 聚丙烯薄膜含有一定量的含PHAE的再生膜和相容剂以显着减少或消除诸如凝胶,空隙等的视觉缺陷。相容剂与再加工的PHAE的使用也有助于改进随后的双轴膜取向和 保持胶片性能。 本发明的实施方案的膜具有优异的外观和美学性能,并且可以适用于取决于配方的透明,白色不透明或金属化膜应用。
