Abstract
A manufacturing process for flexible tube skirts including the steps of providing a multi-layer plastic film, cutting out a strip from the multi-layer plastic film, producing a cylindrical sleeve by rolling-welding the strip, and cutting out the sleeve to the desired length to obtain the tube skirts. The strip is cut out from a multi-layer plastic film which has a symmetrical structure in relation to its median plane, with symmetrical layers having the same thickness and made of the same plastic, having the same chemical composition and the same molar mass.
