Aluminum foil bags are made of pure metal aluminum sheets, and the thinnest thickness can reach 0.0065mm. Although so thin it seems weak, its function is greatly enhanced after being compounded with plastic. After being compounded with one or more layers of plastic, it can improve the barrier properties, sealing, aroma retention, and shielding functions of the plastic.

Aluminum-plated bags, on the other hand, are made by uniformly coating high-purity metal aluminum onto a plastic film under high-temperature vacuum conditions. Because it is coated on plastic, the metal aluminum mainly plays a decorative role and does not significantly help improve the barrier properties of the material.

1. Observation: Because the brightness of aluminum foil is not as bright as that of aluminum plating. Aluminum-plated bags can reflect images, except for matte aluminum plating, which looks very similar to aluminum foil. You can block the mouth of the bag and look inside the bag through strong light. Aluminum foil bags are opaque, while aluminum-plated bags are translucent.

2. Feel: Aluminum foil bags feel thick and heavy, while aluminum-plated bags feel lighter and softer.

3. Folding: Aluminum foil bags easily crease and leave permanent marks, while aluminum-plated bags do not.

4. Twisting: Aluminum foil bags are difficult to rebound after twisting, and the aluminum layer will break. Aluminum-plated bags will quickly bounce back after twisting.

5. Burning: Aluminum foil is difficult to burn with fire, and the aluminum layer will curl back. After burning, the aluminum foil packaging will leave gray aluminum residue. When aluminum-plated bags are burned, different plastic films may burn, and there will be no aluminum residue left.

After carefully reading the differences between aluminum foil bags and aluminum-plated bags above, you will be able to distinguish between them.
