| Product |
High-barrier symmetric structured eleven-layer cast coextruded EVOH film uses cast process, with better flatness, good flexibility, and allows double-sided heat sealing. EVOH layer is a high oxygen barrier layer, and PA layer is a vapor barrier layer. Its high barrier performance can extend shelf life of low-temperature meat products and medical products, and keep nutrient and fresh flavor. Nylon layer ensures the tensile strength and ductility of the film. The film has high transparency, anti-perforation, and good heat sealing effect, can be used on various equipment. It is applied for automatic fresh meat FFS packaging machines, thermoforming stretching machines, water packaging machines, and pillow type packaging machines.
Eleven-layer symmetrical structured coextruded cast film is made of resin materials, such as PA, EVOH, PE, and PP, such as PE/PA/EVOH/PA/PE coextruded film, PP/PA/EVOH/ PA/PE coextruded film, PP/PA/EVOH/ PA/PP coextruded film. PA and EVOH greatly improve the multi-layer film’s barrier to oxygen and odor, compounded peeling strength, resistance to ambient and storage period.
It is applied for packaging of food, chemical materials, and pharmaceutical products with high requirements of oxygen barrier, moisture resistance, and tensile strength.
