Talking about the application of ALOx-PET film in food packaging
ALOx-PET film is a common high barrier material that has been widely used in food packaging laminated films. ALOx-PET film has excellent barrier properties, and it also needs to maintain good integration with other monolayer films during use, such as good composite strength, stable bag-making adaptability and suitable for special use environments.

ALOx-PET film features and differences from ordinary barrier films
The so-called high barrier film, one case, is itself a high barrier material, such as aluminum foil, PVDC film, EVOH film, PVA film, etc.; the other type is multi-layer co-extruded film containing PVDC and EVOH layers; In addition, high-barrier materials adhere to the base film to form high-barrier films, such as various K films, PVA coated films, various aluminized films, and ceramic evaporation films such as ALOx-PET and SiOx-PET.
Therefore, ALOx-PET film is a high barrier material attached to the base film by high barrier material, usually oxygen permeability is: 0.8~1.3ml/(m²·24h,23℃ 0%RH), moisture permeability is 1.2~1.5g/(m²·24h,38℃ 90%RH).
It itself has the following characteristics and comparative advantages:
1.High transparency, relatively environmentally friendly, can be microwave heating, and can pass through metal detectors when used as food packaging;
2.High barrier property, more barrier advantage than K film;
3.Strong stability, less affected by ambient temperature and humidity, which is significantly better than EVOH co-extrusion film and PVA, PVDC coated film;
4.As a printing substrate, the corona value of the evaporation layer is relatively high, which can ensure that the ink adhesion is excellent;
5.After special treatment, the heat resistance is outstanding, and it can be used for boiling and steaming products.
The development of high barrier materials, including ALOx-PET film, is closely related to the development of modern material technology, and evaporation technology will also integrate new processes, such as nanotechnology and the application of nanomaterials in the evaporation process, which can improve the performance and stability of high barrier materials.
The high barrier material is based on biodegradable material, which has the advantages of function and environmental protection. With the increasing functionality and stability, as well as the continuous reduction of the cost of ownership, the application of ceramic evaporation coatings such as ALOx-PET and SiOx-PET, which have high barrier properties, will be widespread.
