  • The difference between aluminum plating and pure aluminum

    Aluminized bag (film) It is a high-temperature vacuum state, uniformly 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 greatly help improve the barrier properties of the material.

    Aluminum foil bag (film) It is made of pure metal aluminum. The thinnest thickness can reach 0.0065MM. If you press it with your hand, it will break. Although it is so thin, it looks weak and windy, but It is compounded with other plastics, and its role is great. After compounding with more than one layer of plastic, it can improve the barrier properties, sealing properties, fragrance retention, shielding properties, etc. of the plastic.

    1. Viewing: Because the brightness of aluminum foil is not as bright as that of aluminized, the reflectivity of aluminum foil is not as good as that of aluminized film. Aluminized bags can show people's shadows, except those with aluminized film and aluminized coating. The appearance of the matte film is similar to that of aluminum foil. You can block the mouth of the bag, look inside the bag through strong light, the inside of the aluminum foil bag is opaque, and the light-transmitting is the aluminum-plated bag.

    2. Feel: The feel of aluminum foil bag is thick and stiff. It is harder and heavier. The feel of aluminum foil bag is lighter and softer than that of aluminum foil bag.

    3. Folding: The aluminum foil bag is easy to fold out the dead mark of the dead fold, the aluminum-plated bag will not be folded into the dead fold dead mark, and it will rebound quickly.

    4. Twisting: After the aluminum foil bag is twisted, the coalescence is not easy to rebound, and the aluminum layer will break. After being twisted, the aluminum-plated bag will quickly disperse and the aluminum layer will not have obvious cracks.

    5. Burning: The aluminum foil is not easy to burn with the fire point, the aluminum layer will be rolled back, and the aluminum foil packaging will leave gray aluminum slag after burning. When the aluminized film is burned, different plastic films can be burned without the residue of aluminum slag.
