摘要

The foil packing is reclosable by a separately applied plastic closure system connected to the packing by welding, glue, mechanical connection or formed by the packing itself. The plastic closure system comprises one of several parts. It can be formed by the folding of several layers of foil, to produce a stiffer part. The stiffer part is used to create an opening in the foil packing. It can be used for closure of the opening. Self-adhesive material can be used on the stiffer and/or underlying part of the packing in order to remove or open a part of the foil packing.
