PET-AIOx transparent high barrier aluminum oxide film Food flexible packaging material film
Introduction:
Metalized film widely used for flexible packing, it has excellent barrier performance,aim to extend the shelf life.
The Metalized PET film is coated with a transparent aluminum oxide layer on the surface of the BOPET film substrate by physical vapor deposition.
It has good thermal stability, high temperature resistance, high strength and stable chemical properties. Compared with co-extruded film, coated film and common metallized film, transparent ALOx metalized film is more environmental friendly, and has better barrier performance and printing performance.

The following is an introduction to its main functions:
1. High barrier property: It can effectively block the penetration of small molecules such as oxygen and water vapor, significantly extend the shelf life of products, and is suitable for packaging of food and medicines with high requirements for freshness.
2. Transparent and visible: While achieving high barrier performance, it maintains good transparency, allowing consumers to intuitively see the products in the package and improve the product display effect.
3. Excellent printing and composite performance: It can be composited with a variety of materials with high quality, and has good printing adaptability, which can meet the processing requirements of different packaging and make the packaging more beautiful and practical.
4. High temperature resistance: It has good thermal stability and can withstand a wide range of temperature differences. It can be directly used for high-temperature boiling or steaming. It also supports direct microwave heating, which is convenient for consumers to use.
5. High strength: It has good mechanical properties such as tensile strength and tear strength, which can effectively protect the products in the package from damage during transportation and storage.
6. Chemical stability: It has good chemical corrosion resistance and can resist the erosion of acid, alkali, salt and other chemical substances. It can be used to package some corrosive products.
Applications:
1. Widely used in Packaging barrier for food such as meat, cooked food, biscuits, candy, dried fruit, tea, coffee, chocolate, dehydrated food, seafood, flavors, etc. and electronics, daily chemicals, food products, pharmaceuticals, etc.;
2. Replace the K (PVDC) coated film to greatly improve the barrier properties of the product and reduce the environmental pollution caused by PVDC. It can be boiled and steaming cooked. It has better visibility and no yellowing;
3. Replacement of BOPA, EVOH and co-extruded film,. It can greatly reduce the cost, greatly improve the barrier performance of the product, and with better adaptability;
4. In place of SiOx, it can greatly reduce the cost. It has softer hand feeling, better transparency, better processing performance and better environmental recycling treatment;
5. Replacing the use of aluminum foil, the composite strength is higher, the cost is lower, it can be see-through, microwave heating, and can be detected by metal;
6. It can replace the common metallized film, has better barrier property and higher composite strength. It can be seen through perspective, can be heated by microwave, and can be detected by metal.
