PE Multi Layer Co-Extrudsion Casting Polyester Film
Product Description:
PP/EVOH/PP coextruded film is a five-layer film. As ethylene-vinyl alcohol copolymers, EVOH, colorless transparent, is an excellent barrier material. It, extending shelf life of goods and providing transparent visual effect, is applied in packaging of food, beverage and easily oxidized products as barrier layer of composites.
EVOH is excellent in oil resistance, organic solvent resistance and long-time fragrance-holding performance and prevents unfavorable gases from penetrating inside.
Since the product is multi-layer extruded, there cannot remain any residual solvents. Meanwhile, because of its easily recovered property and producing no hazardous gases after burning, it is reputed as green environmental friendly material and is gradually gaining attention of the world, showing the most potential market growth trend.
It is widely applied in meat packaging, fresh food packaging and medicine packaging.
Product Performance:
1. With high barrier property, extending shelf life of food and protecting aroma;
2. Good transparence and appearance, good thickness deviation and excellent heat-sealing property;
3. Special layer-to-layer structure to provide excellent mechanical property and processing adaptability;
4. Withstanding high temperature up to 121º C (boiling water). Processing equipments are the latest seven-layer equipments made by German W&H.
Applications:
1. Automatic stretch wrapping of food such as dried bean curds, cooked eggs, fried meat or sausages;
2. Vacuum packaging of sausages, fish or bones, etc.
3. Embossed vacuum packaging.
Kindly Reminder
Please advise the barrier material, thickness, size, style and quantity you prefer and other requirements, we will glad to help you with your choosing the right products and give you the best price.
