Rainbow fluorescent film, is also named as fluorescent film, rainbow film or laser film, which one is different from the colorful plastic polymer film with printing, it is a kind of multi-layer composite film with PVC film or TPU film
The emergence of PET film in the market can be traced back to a few years ago. It may be because the technology is not mature enough, or because there are too few people in the market who know it, and there have been no big waves before.
The pvc film is dedicated to the application of the vacuum laminator on the surface of the board at a high temperature of 110 degrees, so it is not as easy to fall off as the ordinary adhesive film.
PET film is a more comprehensive packaging film. It has good transparency and luster; it has good air tightness and fragrance retention; it has medium moisture resistance, and its moisture permeability decreases at low temperatures.
The CPE film has excellent oil resistance. Among them, it has excellent resistance to ASTM No. 1 oil and ASTM No. 2 oil, which is equivalent to NBR; and it has excellent resistance to ASTM No. 3 oil, which is better than CR and is equivalent to CSM.
TPU film is increasingly popular with people because of its superior performance and environmental protection concept. At present, wherever PVC is used, TPU can become a substitute for PVC.
