The range of stretch-tunability of sinusoidal wrinkled surfaces that are obtained by compression of supported thin films is limited by the emergence of a period-doubled mode at high compressive strains. This disclosure presents a method to suppress the emergence of the period-doubled mode at high strains. This is achieved by compressing pre-patterned supported thin films, wherein the pre-patterns are substantially similar to the natural pattern of the supported thin film system. As compared to flat thin film systems, pre-patterned thin film systems exhibit period doubling behavior at a higher compressive strain. The onset strain for emergence of period-doubling is tuned by altering the amplitude of the pre-patterns.

The invention relates to a method for producing tubular bags made from plastic film or from composite film having a plastic layer on the bag content side, having a self-cutting plastic closure attached to the tubular bag, consisting of a spout part having a fastening flange, a cutting body, which is movably guided in the spout part, and a screw cover having means for activating the cutting body. The film material (5) is supplied from a supply roll to a bag manufacturing machine and the plastic closure is sealed onto the film material in a spout region of a tubular bag. According to the invention, the film material (5) is thinned on the inside of the bag in a ring-shaped region, which is intended for cutting by the cutting body, by means of a thermal embossing process. The plastic closure is then positioned and sealed onto the film material such that the cutting organ embedded in the spout part can become effective in the thinned, ring-shaped region upon use thereof.
