Envelope and Bag Closures
Specialist packaging such as security bags require advanced methods of tamper evidence. By carefully controlling the release properties of the liner for the adhesive coating strip, we can supply a product which releases from the adhesive without prematurely activating the security features. A similar product can be used for a range of self-sealing envelope closures for charity collections, mail-order etc.
