We all know that the stretch film is generally colorless and transparent, or solid color black, blue, yellow and other color films, there are few other colors, so why do some stretch wrap films appear yellowish?
The color of the stretched stretch film is light yellow, which is mainly caused by the temperature control during production. The stretched stretch film has developed into a mature production process today. Some manufacturers will try to change the formula to produce different properties of the stretched film, mainly reflected in Three aspects: color, stretch rate and self-adhesiveness. A single color change does not necessarily affect the use of the stretched film. It is known that many times the melting temperature of the film is changed due to the different melting temperatures set by the process, but not Will affect the transparency, this is a good stretch film, if the stretch rate and self-adhesive properties are reduced, it is a poor stretch film, may be mixed with other impurities.
In fact, strictly speaking, the stretched film is only colorless and color. The yellowish color is mainly caused by additives such as dov, color masterbatch or processing technology. If the color is light, the stretch rate and self-adhesiveness are not affected. If the color is not natural, the general quality will be very poor.
If the stretch film is light yellow, but the transparency, stretch rate, and self-adhesive are unchanged, and there is no odor, it can be used. If the four indicators change, do not use it again.
