Aluminum foil bag packaging usually refers to aluminum-plastic composite vacuum packaging bags. These products are suitable for moisture-proof, light-proof and vacuum packaging of large-scale precision machinery and equipment, chemical raw materials and pharmaceutical intermediates. It adopts four-layer structure and has good water-proof and oxygen-blocking functions. Unrestricted, you can customize the bags of different specifications and styles, which can be made into flat pockets, three-dimensional bags, organ bags and other styles.
The material of the aluminum-plated bag is generally composite: PET+VMPET+PE, and it can also be compounded according to any material and thickness specified by the customer. The types of bags made can be made into flat pockets, three-dimensional bags, medium-sealed bags, yin-yang bags, and organ bags, just like aluminum foil bags.
The difference between aluminum foil bags and aluminum-plated bags:
Aluminum foil bag (film) It is made of pure metal aluminum. The thinnest thickness can reach 0.0065MM. If it is lightly rubbed by hand, it will break. Although it is so thin, it looks weak and windless, but It is compounded with other plastics, and its function is very large. After compounding with more than one layer of plastic, it can improve the barrier properties, sealing properties, fragrance retention and shielding properties of plastics. Aluminized bag (film) It is a high-temperature vacuum state, evenly coated with high-purity metal aluminum on the plastic film. Because it is coated on plastic, metal aluminum mainly plays a decorative role, which does not help greatly improve the barrier properties of materials.
1. Watch: Because the brightness of aluminum foil is not as bright as that of aluminum plating, the reflective properties of aluminum foil are not as good as those of aluminum-plated film. Aluminized bags can be used to illuminate people, except for matte-coated aluminum. The aluminized appearance of the matte film is similar to that of aluminum foil. You can block the mouth of the bag and look inside the bag through strong light. The inside of the aluminum foil bag is opaque, and the light is the aluminum-plated bag.
2, feel: aluminum foil bag feel thick and stiff and hard, aluminum-plated bag feels lighter and softer than aluminum foil bag.
3, folding: aluminum foil bag is easy to fold out the dead pleats, the aluminum-plated bag will not fold into a dead pleats, and will rebound soon.
4. Twisting: After the aluminum foil bag is twisted, the coalescence is not easy to rebound, and the aluminum layer will break. When the aluminum-plated bag is twisted, it will quickly squirm and will spread out, and the aluminum layer will not have obvious cracks.
5, fire: aluminum foil with fire points is not easy to burn, the aluminum layer will rewind, after burning aluminum foil packaging will leave gray aluminum slag. When the aluminized film is fired, different plastic films may be burned, and no residue of aluminum slag remains.
