This patented hook-to-hook closure is made from food-grade, heat-sealable polyethylene material, designed to be sealed on film. Self-mating micro hooks engage on multiple levels, making it easy for anyone to open and reclose their flexible packaging. Unlike other zip closures and press-to-close systems, precise alignment is not required for closing. Its sensory appeal make it both fun and functional for the entire family!
