The reason why PET plastic strapping is not firm
why pet is not film? we can find below reason, 1. Firstly, the friction time of the baler may not be preset well. When bonding at the interface, the temperature is too high or is not high enough to cause instability. 2. It is also possible that there are too many stains on the linings of the balers. Therefore, the friction is weakened during packing, so sandpaper can be used to polish the stains before packing to ensure cleanliness. 3. Tilting of the friction plate will also cause the package...

Analysis of the problem of black stretch film rupture
In fact, in our actual use, it is not uncommon for the black stretched film to break the film. Especially for some stretched films with relatively low thickness, this problem often occurs, and the transverse pull film is relatively common. A problem with this problem is as follows: 1. The further expansion of various inconspicuous rupture factors will lead to excessive local area. 2. When used, there are obvious horizontal stripes and bubbles on the cast piece. 3. In the production process, the...

At the same time, due to improper disposal in the process of...
The cause of static electricity in the film
There are several reasons for the static electricity generated by the film: Static electricity generated when producing film Because the particles rub against each other, the friction between the melt and the die, the film is wound up and the guide roller is rubbed, causing the film to generate static electricity at the time of shipment. Therefore, an antistatic agent is added during the film production process to eliminate this part of the static electricity. It should be said that this effect...
