When purchasing thermal insulation materials, do you choose to buy aluminum coated tape or Aluminum foil tape What about? Do you understand the difference between aluminum tape and aluminum coated tape?
The base material of aluminum tape is aluminum foil, and the adhesive layer uses high-quality pressure-sensitive adhesive. Aluminum foil has thermal insulation performance. When used in electronic products, the purity of aluminum foil of aluminum tape is higher than 99.95%, which can play the role of electromagnetic shielding. When used outside the steam pipe, it can prevent temperature loss. Aluminum tape can also be used in refrigerator, air conditioner, automobile, petrochemical, bridge, hotel, electronics and other industries.
The aluminized tape is made of high-quality aluminized film coating and high-quality pressure-sensitive adhesive. The aluminized film is a kind of composite flexible packaging material formed by coating a very thin layer of metal aluminum on the surface of plastic film with a special process. It not only has the characteristics of plastic film, but also has the characteristics of metal. It is a kind of cheap and beautiful packaging material with excellent performance and strong practicability.
The role of aluminum coating on the film surface is to block light and prevent ultraviolet radiation, which not only extends the shelf life of the contents, but also improves the brightness of the film, replacing aluminum foil to a certain extent, and also has cheap, beautiful and good barrier performance. Therefore, aluminum coating is widely used in composite packaging, mainly used in dry and puffed food packaging such as biscuits, and some medicine On the outer package of cosmetics.
What's the difference between aluminum tape and aluminum coated tape?
1. Prices are different. Because the aluminum content is different, aluminum coated tape is cheap, and aluminum foil is expensive.
2. The aluminum layer of aluminum tape is thick, so it has strong light shielding performance. The aluminum coated tape is extremely thin, so it has poor light shielding performance.
3. The reflective property of aluminum tape is not as good as that of aluminum coated tape. However, the refraction and shielding properties of aluminum foil are better than that of aluminized film. The aluminum foil package is silver white or silver gray, and the aluminum plated film package is silver yellow or silver black.
4、 The package of aluminum foil has a thick, firm and heavy feel, and the package of aluminized film is lighter and softer than that of aluminum foil.
5、 The barrier property of aluminum tape (shading, blocking material penetration) is stronger than that of aluminum coated tape.
6、 After the aluminum foil package is twisted, the coalescence is not easy to rebound, and the aluminum layer will break. After the aluminum coating film package is twisted, the kinks will spring apart quickly, and the aluminum layer will not have obvious cracks.
