Memory strip is an aluminium strip welded to the inner side of the film in the upper part of the bag, parallel to the upper lateral weld. The contents of the bag are protected against spilling. Memory strip helps to retain the aroma of the products, as well.
The bag is opened by cutting open the upper weld. It can then be reclosed by folding the welded-on memory strip, which keeps the film of the packaging material folded.
Memory Strip can also be applied to pillow bags and folded bottom bags. The maximum output of a machine equipped with Memory Strip is 100 bags/min.
