I. What Are Plastic Zipper Bags?
Plastic zipper bags are packaging containers featuring a prefabricated zipper structure for repeated opening and closing, boasting both sealing performance and user-friendliness. Their unique zipper design effectively protects contents from moisture and dust, extends shelf life, and supports reusable use to reduce resource waste. Currently, they are widely used in food, daily chemicals, electronics, pharmaceuticals and other industries, emerging as a key choice for modern packaging solutions.
