Stretch film can prevent moisture and dust for the packaged products. They can be packaged together to avoid scattering. So for the sake of safety, we also need to have an in-depth understanding of the standard of use of the product. So, what are the basic requirements for the quality of stretched film?

 

1. There is no black impurities, the die should be washed clean, and the burnt plastic should not be dropped. If it is found by the naked eye, it must be removed immediately.

2. The paper tubes must be aligned, not long on one side and short on the other side, and the standard of white space on each side is about 1 cm.

3. When packing, pay attention to protect the edges from collisions. The edges will break and cause quality problems. As long as there is a crack in one place, it will lead to the phenomenon of breaking when the stretch film is used. This is why there should be no burrs.

4. Minimize the wrinkles on both ends of the surface and the white pressure line in the middle, which will seriously affect the appearance.

5. The edge material should be cut neatly if the edge material is broken, and the cutting deviation cannot be shipped as a finished product. Both ends must be neatly rolled up, including products made.
