Flange Zipper Overview
A flange zipper is a press-to-close zipper profile with extended sealing flanges on both sides of the interlocking track. The wider flange area allows the zipper to be heat sealed or integrated more securely with flexible pouch films during bag production.
Flange zippers are commonly selected for stand-up pouches and other flexible packaging where stable zipper-to-film attachment, repeated opening and closing, and production-line compatibility are important.
The suitable zipper material and structure depend on the pouch film, inner sealant layer, sealing temperature, bag size and filling weight.
