摘要： The present invention relates to a thermoformable, multilayer, co-extruded adhesive-free and EVOH-free film containing polyamide, polyolefins, and/or copolymers based on olefins. This film is particularly suitable for the packaging of products that have been subjected to a heat treatment in thermoformed films. The films are characterised by an outer layer of polyamide and a second outer layer of polyolefins or coploymers based on olefins, wherein the film composite does not delaminate even at temperatures between 50null C. and 150null C.
摘要翻译：本发明涉及含有聚酰胺，聚烯烃和/或基于烯烃的共聚物的可热成型，多层共挤出的无粘合剂和不含EVOH的膜。该膜特别适用于在热成型膜中经受热处理的产品的包装。膜的特征在于聚酰胺的外层和基于烯烃的聚烯烃或共聚物的第二外层，其中即使在50℃和150℃之间的温度下，膜复合材料也不会分层。

摘要： Described is a thermoformable film comprising at least one layer (I) of polyamide containing solid anisotropic fillers (A) and individual spherulites. The anisotropic fillers (A) of the layer (I) of the thermoformable film, in a number-weighted average of all the dispersed constituents of the anisotropic fillers (A), have a dimension of no more than 10 nm in at least one first direction (r1) freely selectable for each dispersed constituent and, in at least one second direction (r2) perpendicular to the first direction (r1), have a dimension of at least 50 times the dimension in the first direction (r1). The individual spherulites in the layer (I) have a number-average distance from each other of no more than 50 nm, and the cores of a majority of the individual spherulites in the layer (I) are free of a filler particle of the anisotropic fillers (A). Also described is a method of preparing the thermoformable films of the present invention, and methods of using the films for, for example, packaging foodstuffs.
摘要翻译：描述了包含至少一层含有固体各向异性填料（A）和单个球晶的聚酰胺层（I）的可热成膜。可热成形膜的层（I）的各向异性填料（A）在各向异性填料（A）的所有分散组分的数均加权平均值中，在至少一个第一方向（r1）对于每个分散的构件可自由选择，并且在垂直于第一方向（r1）的至少一个第二方向（r2）上具有至少第一方向（r1）的50倍的尺寸。层（I）中的单个球晶彼此之间的数均距离不超过50nm，层（I）中大部分单个球晶的芯不含各向异性的填料颗粒填料（A）。还描述了制备本发明的可热成膜的方法，以及使用该膜用于例如包装食品的方法。
