Production standard of PE stretch film

There is a standard for the production of each product. What is the production standard of PE stretch film? As a professional packaging film manufacturer, let me introduce the production standard of our company's pe film. The main points are as follows:

1. PE stretch film requires no black impurities, the die should be cleaned, and there should be no burnt plastic falling in. The naked eye can be found.

2, the paper tube used for PE stretch film must be aligned, not one side long and short. White standard 1CM on each side.

3. PE stretch film should pay attention to the edge of the protective edge when it is packed, so that the edge crack will cause quality problems. Can't have burrs.

4. Minimize the wrinkles on both ends of the PE stretch film and the white pressed lines in the middle.

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.
