Aluminum-plastic composite film is divided into two types: aluminum-plastic film and aluminum-plated composite film:
Aluminum-plastic film
Folded structure composition
1. PET/ aluminized CPP(lightweight product structure)
2. PET/AL/PE(structure for use below 10KG)
3. PET/AL/CPP(pesticide application structure)
4. PET/AL/NY/PE(heavy packaging structure)
Aluminized composite film structure
A. PET aluminum +PE
Aluminum foil composite film is the most commonly used composite roll film, usually containing pure aluminum (AL) and aluminum plating (VMPET). Aluminum foil is an extremely thin sheet formed with high-purity aluminum after repeated calendering. It is an excellent heat conductor and light blocker.The purity of aluminum foil used in packaging is above 99.5%.
B. Vacuum aluminizing film is a kind of film which deposits the vapor deposition of aluminum onto various substrate films in a high vacuum state. The thickness of the aluminizing film is generally 350 to 400A.
The film requires a lot of indicators, one of the most important indicators is different from the common composite film is: (1) extremely high barrier; (2) good cold stamping molding; (3) puncture resistance; (4) stability of the electrolyte; Electrical properties (including insulation).
It can ensure that the humidity in the package bag is less than 40RH; Moisture-proof effect is 80 times of ordinary polyethylene; There are various specifications, sizes and materials of the composite film to choose from; Good protective properties: oxygen resistance, moisture resistance, puncture resistance, high strength, high toughness, one-way or two-way breathable, anti-ultraviolet, anti-chemical, such as anti-oil, oil and acid and alkaline substances. Aluminum-plastic composite bag: choose aluminum-plastic composite, aluminum-plated composite, aluminum-plated composite +PE inner bag, kraft aluminum foil composite; 25kg kraft paper bag; Multi-layer kraft paper, kraft paper PE composite, kraft paper + aluminum foil inner bag, kraft paper +PE inner bag, kraft paper aluminum foil composite; PE bag: choose multi-layer co-extrusion of high strength PE film; Jam, tomato juice and various liquids. Electrostatic shielding film/bag: outstanding performance, very excellent industrial supporting materials, innovative electrostatic release technology and stable and lasting performance. Applicable to: electronics and defense advanced products packaging.
