Domestic filth and waste storage bag, has weld line whose top ends define length lower than length between lateral borders and line, so that elastic strip undergoes lengthening to maintain bag on top edge of receptacle

摘要

The bag has a weld line (19) delimiting shrinkage areas and extending from lateral borders (2, 3) of the bag towards the inside of the bag. Top ends of the weld line define a length (L2) lower than the length (L1) between the lateral borders and the weld line, so that an elastic strip undergoes lengthening to maintain the bag on a top edge of a receptacle.
