摘要

One piece bag for both sterilisable and non-sterilisable filler materials consists of an aluminium/thermoplast laminate, and has a W-shaped bottom fold enabling the bag to stand in an upright position. The two elbows of the W-shaped bottom fold are bonded together in the region of the longitudinal seam by welds having a large surface area, these being effected in the outer thermoplast layer. Bag has a very strong construction in the bottom region. This enables the bag to be stood in an upright position, and is resistant to sterilisation temps. and impacts.
