SHEET-LIKE COMPOSITE FOR PRODUCING DIMENSIONALLY STABLE FOOD-PRODUCT CONTAINERS HAVING A BIOBASED BARRIER LAYER

The invention relates to a sheet-like composite comprising as layers of a layer sequence from an outer side of the sheet-like composite to an inner side of the sheet-like composite a) a carrier layer,and b) a barrier layer; said barrier layer a. comprising a polyamide, and b. being characterized by a methylene/amide coefficient, as determined in accordance with the method described herein, in a range from 0.3 to 0.7. Furthermore, the invention relates to a container precursor, to a closed container, to production methods for the aforementioned and to a use of a polyamide in a barrier layer ofa sheet-like composite having a carrier layer for producing a food-product container. 本发明涉及种片状复合材料，其包括从片状复合材料的外侧到片状复合材料的内侧上作为层序列的层：a)载体层，和b)阻挡层；所述阻挡层a.包括聚酰胺，且b.所述阻挡层的特征在于根据本文所述的方法测定的亚甲基/酰胺系数在0.3至0.7的范围内。此外，本文涉及种容器前体，涉及种密闭容器，涉及生产前述容器前体和密闭容器的方法，还涉及片状复合材料的阻挡层中的聚酰胺在生产食品容器中的应用，其中所述片状复合材料具有载体层。
