Hot Lock Bag is an open mouth paper bag that allows the filler clean and easy closure of the bag without handling of additional items such as threads for sewing or adhesive strips.
At the top of the bag hot melt is applied during bag production which allows optimal closure of the bag after filling through reactivation of the hot melt in the filling process. The bottom of the bag has a standard cross bottom shape, which provides more stability during transportation of the bag in the packaging line. It also gives better stacking of the filled bags on the pallet.
It could be the ideal solution for food, pharmaceutical and chemical ingredients. The bags are mainly used with PE-inliner and are geared to be used with high end packaging lines.
