The difference between PE heat shrinkable film and dyed film

PE heat shrinkable film manufacturers have many types of protective film, and metal plate protective film and dyed film are the most common two. Although the appearance of the two films is similar, if you observe carefully, they will still be different. The main differences are as follows: 1. Metal protective film: at least six layers of structure, including two original film layers, a metal layer, and a wear-resistant layer , A transparent adhesive layer, a clutch paper layer. The metal layer and the wear-resistant layer greatly change the effect of the explosion-proof insulation and the wear resistance of the explosion-proof film. There are also two processes for metal film. Better metal film uses electroplating technology, while ordinary metal film uses glued metal layer printing technology. 2. The dyed film only has a three-layer structure: the original film layer, the glue layer, and the clutch paper layer. Therefore, in addition to the color of the film, the explosion-proof and heat-insulating function is very poor. Because the color of the dyed film is to dye the glue layer, and the glue is prone to oxidation and discoloration, the dyed film is easy to fade. 3. The dyed film has the characteristics of discoloration, but the metal film does not. Next: The advantages of PE heat shrinkable filmPrevious: How to detect the quality of protective film
