What Are The Materials Of Stretch Film Wholesale?

Stretch film is used in the sale and transportation of various products, and its main function is to stabilize, cover and protect the product. Stretch film must have high wearability, good shrinkage and certain shrinkage stress.
During shrinkage, the film cannot create pores. Since stretch film is usually suitable for outdoor use, it is necessary to add anti-ultraviolet agents. The stretch film adopts a three-layer co-extrusion casting process, with imported linear low-density polyethylene as the main raw material. So how is it made?
1. There is no black impurity, the mold head should be cleaned, the burnt plastic can not fall in, if the naked eye can find it must be removed immediately.
2. The paper tubes of the drawing film must be aligned, not long on one side and short on the other, leaving a white standard of about 1 cm on each side.
3. Minimize the surface folds at both ends of the stretch film and the white compaction line in the middle
4. If the edge material of the stretch film is broken, it should be cut neatly. If the cut is uneven and cannot be transported as a finished product, the ends must be rolled neatly when producing the goods, not more on one side and less on one side.
5. Pay attention to protect the edge of the stretch film when packing, do not produce collision phenomenon, cause quality problems caused by edge cracking (as long as there is a little crack, it will cause the customer to break when drawing the film), and there can be no burrs.
