Stretch film manufacturers use imported resin and advanced flow-diffuser film extrusion production process, which has good tensile properties, tear resistance, strong penetration resistance, high transparency, good self-adhesiveness and high retraction rate, and tight packaging. It will not be loose and so on, and it also needs to implement strict production standards in the production process.
1. No black impurities, the die should be cleaned, and there should be no burnt plastic falling in. The naked eye can be found. The paper tubes must be aligned and not long and long. White standard 1CM on each side.
2, when packing, pay attention to the protection edge, do not collide, resulting in quality problems caused by edge rupture. Can't have burrs.
3. Minimize the wrinkles on the surface of both ends and the white pressed lines in the middle.
4. If the material is broken, it must be cut and tidy. If the cut is uneven, it cannot be shipped as a finished product. Including the goods must be rolled up at both ends, not more than there.
