What are the three layers of aluminum plastic film?
Aluminum plastic film is one of our common aluminum foil films. Aluminum plastic film can be a three-layer structured composite film, or it may be a four- or five-layer material composite film.
The three layers can be divided into different structures depending on the application.
Our commonly used material is PET/AL/PE, which has a very good stability and is widely used in food packaging, pharmaceutical packaging, industrial packaging and other industries.
PET: material as a steel material, not only has a certain barrier performance, and physical properties are very superior, the appearance of glossy, brace characteristics.
Very suitable for gravure printing, so that aluminum plastic film in the color embodiment, printing effect, color levels have a good display effect, as the surface layer can be with a variety of
As a surface layer, it can be compounded with a variety of other materials and is a very good printing layer material.
AL: Aluminum foil, as the middle layer of aluminum plastic film, not only has a unique metallic texture and very good shading, providing good conditions for some products that need to avoid light.
Not only that, the most outstanding feature of AL is its barrier performance, which is very suitable for moisture barrier, oxygen barrier, and fragrance preservation, if you need specific barrier data, please consult Shenkai.
PE: heat sealing layer is non-toxic and harmless can be directly with food food, has good tensile strength and heat sealing performance, is the most common heat sealing material.
Three-layer composite aluminum-plastic film will also have a variety of different variations according to the needs of different contents, the unchanging research and development of flexible plastic packaging technology has led to more efficient and environmentally friendly
The unchanging research and development of flexible packaging technology has led to more efficient and environmentally friendly three-layer material aluminum plastic films. The development of flexible packaging technology has led to more efficient and environmentally friendly three-layer films.
