Aluminum foil bags and aluminum-plated bags are common packaging bags in our daily lives ， They are currently widely used in the clothing, food, and cosmetics industries, but many people who don't understand the difference between aluminum-plated bags and aluminum foil bags cannot distinguish between them which is aluminum-plated bag and which is aluminum foil bag, so we should how to identify whether the material used in aluminum-plastic composite flexible packaging is aluminum foil or vacuum-plated aluminum film? ? Let's follow the flexible packaging manufacturer Shunxingyuan Packaging to learn more.

Aluminum foil bags are made of pure metal aluminum sheets, and the thinnest thickness can reach 0.0065mm. Although it looks weak and flimsy, it plays a significant role after being laminated with plastic. After being laminated 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 are made by uniformly coating high-purity aluminum on a plastic film under high-temperature vacuum conditions. Because it is coated on plastic, the aluminum mainly plays a decorative role and does not significantly improve the barrier properties of the material.

What are the differences between the two?

  1. In terms of materials, aluminum foil bags are pure aluminum, with high purity and are soft materials; aluminum-plated bags contain composite materials and are brittle materials.

  2. In terms of cost, aluminum foil bags are more expensive than aluminum-plated bags.

  3. In terms of performance, aluminum foil bags they have better moisture-proof and cooling effects than aluminum-plated bags, aluminum foil bags completely light-proof, while aluminum-plated bags have a light-shielding effect.

  4. In terms of use, aluminum foil bags are more suitable for vacuum packaging, such as cooked food and meat products, while aluminum-plated bags are suitable for tea, powder, and electronic components.

  5. Hold the bag up to the light or sunlight. If you can see light through the bag, it is an aluminum-plated bag ; if you cannot see light, it is an aluminum foil bag.

Here are some other ways to identify aluminum-plated bags and aluminum foil bags

1. By observing and comparing aluminum-plated bags and aluminum foil bags Because the brightness of aluminum foil is not as high as that of aluminum plating, the reflectivity of aluminum foil is not as good as that of aluminum-plated film. Aluminum-plated bags can reflect a person's shadow, except for matte aluminum plating. Matte aluminum plating 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. By touching aluminum-plated bags and aluminum foil bags Feel: Aluminum foil bags feel thicker, firmer, harder, and heavier, 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 crease permanently and quickly rebound.

4. By twisting aluminum-plated bags and aluminum foil bags Aluminum foil bags are difficult to untwist after twisting, and the aluminum layer will break. Aluminum-plated bags will quickly untwist after twisting, and the aluminum layer will not have obvious cracks.

5. By burning aluminum-plated bags and aluminum foil bags Aluminum foil bag is difficult to burn with fire, the aluminum layer will curl up, and after burning, aluminum foil bag will leave gray aluminum residue. Aluminum-plated bag bags may show different burning conditions of plastic films when burned, without any aluminum residue. 。
