Versapak T2 seals work with tamper evident bags featuring the patented T2 locking chamber as part of the zip closing security on the bag. It works by placing the zip puller into the locking mechanism and fixing a T2 security seal in place to make the bag tamper evident. When someone lifts the zipper, the seal breaks which means that you can see immediately that the bag has been opened. Fully recyclable and environmentally friendly, the T2 Seal is made from 100% returned or remoulded plastic sourced from plastic wastage before it is sent to landfill. Free Versapak scheme available for return of used seals to reduce plastic waste.
