The new packaging adopts a high-performance three-layer composite structure of 25μm OPP printing film + 15μm food-grade PE extrusion lamination + 25μm VMCPP film. Different from traditional single-layer film or glue-based dry lamination, it adopts glue-free extrusion lamination technology for intermediate bonding, featuring zero residual glue, low odor, and high food safety. The upgraded VMCPP vacuum aluminized inner layer adds excellent light-shielding, oxygen and moisture barrier capabilities, fully complying with international food-grade packaging standards, and is perfectly suitable for nuts, puffed snacks, baked goods, and other light-sensitive, easily oxidized snack products.

The three-layer integrated structure delivers comprehensive and upgraded functional performance. The outer OPP layer ensures rigid and flat packaging appearance; the middle PE extrusion lamination layer provides firm bonding, excellent oil resistance and moisture resistance; the inner VMCPP vacuum aluminized layer achieves full light blocking and ultra-high barrier performance, effectively isolating light, oxygen and moisture in the external environment. This multi-layer structure perfectly locks the original flavor and crisp texture of snacks, greatly prolongs product shelf life, and avoids deterioration and taste loss during storage and transportation. Meanwhile, the overall pouch boasts high toughness, strong pressure resistance, no delamination or bubbling, and stable structural performance, adapting to long-distance sea freight, high-temperature and humid transportation environments, as well as long-term supermarket shelf display.

In addition to quality upgrades, the new packaging solution balances cost efficiency and practicality. With stable mass production capability, it supports customized sizes, personalized printing designs, and different packaging styles for branded snacks, wholesale retail, and export orders. Strict factory inspection and standardized production processes guarantee consistent batch quality for every shipment.
