The pull-tight PL 91 seal is versatile. In particular, it is used to secure tank vehicles, e.g. for food, boxes with lids and other containers, roll cages, flaps, doors, cupboards, lids e.g. for silos, and bags and sacks.
The indicative seal is made of polyethylene and has a locking mechanism made of the temperature-resistant plastic acetal integrated into the seal flag. The seal flag is printed with a 6-digit sequential number and can optionally be supplied printed with a barcode, logo or short text of up to 34 characters. To close, the tail is pushed through the locking mechanism.
The pull-up seal should always be firmly tightened when putting on.
