Stretch film requirements

Stretch film requirements

1.  The paper tube must be aligned, not one side long and one side short.  The standard for whitening on both sides of the stretched film is about 1 cm.

2.  Minimize the wrinkles on the surface of both ends and the white pressed lines in the middle (this will seriously affect the aesthetics).
3, no black impurities, the die should be washed clean, can not be burnt plastic into the plastic, if the naked eye can be found must be immediately cleared.

4, when packing, pay attention to the protection edge, do not collide, resulting in quality problems caused by edge rupture, can not have burrs.

5, when 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.
