Strong steam-sterilizable multible-layer film, and packages for physiologic solutions, made therefrom

Abstract From the Canadian patent

The invention relates to a strong and steam-sterilizable multiple-layer plastic film for packaging physiologic solutions, and to a strong and sterilizable package made of, this film, for physiologic solutions. Since the conventional plastics used for packaging physiologic solutions turn brittle under steam-sterilization, a new type of multiple layer film has been invented which has, especially after steamsterilization, mechanical properties superior to those of a conventional plastic film. The film according to the invention is produced in such a way that at least one layer is a mixture of polyolefin, preferably polypropylene and an elastomer. In, this manner the resistance to flex crack …
