PE stretch film at the time of production. There will be some obvious changes on its surface. Especially the color change. In fact, this clearly reflects its current status and quality. So why is it pale yellow? Next, let's analyze it briefly.
Strictly speaking, PE stretch film has only colorless and color. The appearance of light yellow is mainly caused by additives. Such as dov and color masterbatch or changes in processing technology. If the color is light, the elongation and self-adhesion are not affected. If the colors are unnatural, the quality is generally poor.
The development of production technology is very mature today. Some manufacturers will try to change the formulation to produce PE stretch films with different properties. It is mainly reflected in three aspects: color, elongation and self-adhesion. A single color change does not necessarily affect its use. It is important to know that the melting temperature is often set differently due to processing. Will cause color changes. But it does not affect the transparency, this is a good film. If the elongation and self-adhesive properties decrease, it is a poor film. May be doped with other impurities.
If the color of PE stretch film is light yellow. However, there was no change in transparency, elongation, and self-adhesion. It has no odor and can be used. If the four indicators change, do not use them.
