The stretched film has excellent self-adhesiveness, high tensile strength and tear strength, and can prevent the product from falling and falling during transportation. However, sometimes PE stretch film is often used during the process, and it will show wrinkles, which will seriously affect the packaging effect. Why is this phenomenon present:

1. The azimuth deviation of the stretched film substrate causes the composite film to wrinkle, and the degree of wrinkling increases correspondingly with the accumulation of skewness. Stretch film 

2, PE stretch film substrate thickness is not uniform, the thickness difference is too large. Or the compound pressure of the packaging machine is not set properly.

3, tension setting and control is not appropriate, the tension of each part is not coordinated, does not match.
4. The axis between the silicone rubber press roll and the cooled steel roll is not parallel.
5. The outer surface of the guide roller is unclean, and there is foreign matter sticking to it, or the outer surface of the guide roller is not flat, and there are pits, scribes, bumps and the like.
The PE stretch film is normally used and should be flat and smooth. If it is wrinkled, it will also prevent its stickiness. The packaging of the goods is not only unsightly and not tight, so it can not be used to maintain the goods. It is necessary to adopt corresponding measures to produce PE stretch film reasonably and correctly.

PE stretch film is a commonly used packaging film. It has high flexibility, is not easy to break, has strong tear resistance, strong tensile strength, etc. It can replace the box packaging, but if the shipping maintenance is not proper or the application is not appropriate The PE stretch film is damaged. Let's analyze the reason why the PE stretch film is damaged: the transport maintenance is not proper: it means that the PE stretch film is in the process of transfer, if the box is damaged, it will wear around the edge of the film. So that it will simply show cracking during the application process, affecting its application. When it is wrapped, the damage will be torn, resulting in the inability to package the goods. Inappropriate use: It means that the surrounding film machine is not well fixed, and the remaining parts will scratch the appearance of the film, so that the surrounding film will be damaged. If the packaging temperature of the PE stretch film is too high, or the working environment is too high, it will soften the surrounding film. It also causes cracking of the PE stretch film. The above is the reason why the PE stretch film is damaged. We hope that we can pay attention to the maintenance of the product when transporting the PE stretch film to avoid the impact of damage.
