POLYMERIC FILM FOR MANUFACTURING COVERS FOR SINGLE-DOSE CAPSULES FOR COFFEE MACHINES, AND METHOD FOR PRODUCING IT

摘要

A method for providing a polymeric film for manufacturing covers for single-dose capsules for coffee machines, comprising the following steps:
- mixing a deformable polymeric matrix with a filler of non-deformable embrittlement particles;
- extruding by film forming the resulting mixture, so as to provide a film;
- orienting the polymeric chains of the polymeric matrix and the non-deformable particles of the filler along one or more main directions.
