High-barrier EVOH multilayer co-extruded material is an advanced flexible plastic film formed by compounding different polymer layers through a single process. With EVOH (ethylene-vinyl alcohol copolymer) as the core inner layer, this material effectively blocks oxygen, gases, and aromas, thereby extending the shelf life of sensitive products.
7-Layer 9-Layer and 11-Layer Co-extruded Film: utilizes a 7-layer 9-Layer and 11-Layerco-extruded structure to effectively block air, providing moisture and mold protection.

The advantage of EVOH?
Evoh is a premium, flexible thermoplastic prized for its exceptional gas barrier capabilities. Its primary advantage is effectively blocking oxygen and other gases, which prevents spoilage, preserves natural flavors, and vastly extends the shelf life of food, medical, and industrial products.EVOH is one of the most effective oxygen and gas barriers available. It almost completely cuts off the supply of oxygen, protecting against fat oxidation, color degradation, and the growth of aerobic bacteria.It locks in natural aromas and flavors while simultaneously blocking external, unwanted odors from penetrating the packaging.EVOH provides exceptional optical properties-offering high gloss, low haze, and supreme transparency so consumers can easily view the packaged contents.It retains its structural integrity in the presence of oils, organic solvents, and agricultural chemicals, making it ideal for non-food uses like automotive fuel tanks.EVOH is easy to co-extrude with a variety of other polymers (like PE, PP, or PET) to create thin, multi-layer films that deliver maximum performance with minimal material.
