A Thinner Closure for Resealable Stand-Up Pouches
3M™ Grip Lock Strip is a structured film (hook to hook) system designed for re-closing stand-up pouches. It is comprised of a flat film and an array of small hooks designed to interlock with one another when pressed together. When closed the strip is up to 60% thinner than typical closures yet still provides a secure seal that can be felt. The flangeless polymeric backer is heat activated for attachment to a wide range of bag and pouch films.
