May 31, 2019
PE protective film is generally divided into two types, one is oil-free without release liner, and the other is water-based adhesive with release liner. The above two are composed of three parts, which are plastic coated silicon release paper, glue, PVC plastic mask. Oil-adhesive composite film is not called PE protective film because it is used differently. It is mainly used in advertising production, such as computer engraving. The effect of oil glue is that the characters and patterns are not easily deformed, suitable for long-term. Posting is not easy to curl and fall off. Such products such as sticky notes, furniture stickers, sign stickers, etc.
PE protective film is a water-gel composite maintenance film, mainly used for engraving art glass, as well as surface maintenance of other items. Water glue is the Amin glue series. This kind of glue is non-toxic and harmless to the human body. It is a green and environmentally-friendly glue that meets the requirements. PE protective film first requires no degumming. After the glass is finished, when the maintenance film is removed, the surface of the processed glass product can not leave a little glue and traces to keep the product bright and beautiful.
Secondly, the PE protective film is required to have good toughness, and the mask can withstand the impact force of the sprayed diamond to 6-8 kg, otherwise it will break through the maintenance film and break the processed object. At the same time, it is necessary to have proper viscosity. The mask can be applied to the glass body to be repaired and firmly, and the maintenance film can be smoothly removed after the processing is completed, so as not to be unnecessary due to brittle fracture and shredding. It’s troublesome.
In addition, the color and specifications of the film should be maintained, which can be customized according to the requirements of the user. The commonly used colors are white and light yellow. The length is in meters and is customized according to user requirements. Maintaining the quality of the film directly affects the working time and the quality of the product.www.xmlfilm.com
