Abstract
The invention relates to films of polymers of high molecular weight, which have been obtained by casting polymers dissolved or swollen in solvents and partially contain stiffened segments, which films serve either for decorative, handling or fixing purposes or allow, especially when formed on the film edges, a particularly ultrahigh stretching of the films without excessive formation of lips.
