Abstract: 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 steam-sterilization, 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 formation can be improved about 10-fold.
