Description
Product Overview
This BOPP VMPET PE stand up zipper pouch is widely used for dry puffed snack packaging. The 3-layer composite structure combines BOPP outer printing layer, VMPET metallized barrier layer and PE inner heat seal layer. It is designed for shelf display and long-term freshness protection for dry food like pea crisps, nut mixes and cereal snacks.
The outer BOPP film provides brilliant printing effect for custom artwork. The middle VMPET metallized layer creates a light, oxygen and moisture barrier to prevent oil oxidation and moisture absorption, keeping snacks crispy during storage. The inner PE layer ensures stable heat sealing, compatible with stand-up bottom gusset and resealable zipper.
