How to solve the phenomenon of wrinkled agricultural film

Agricultural film, also known as film plastic, includes mulch film (also called agricultural mulch film), the main component is polyethylene. Mainly used to cover farmland, play a role in improving ground temperature, maintaining soil moisture, promoting seed germination and rapid growth of seedlings, as well as inhibiting the growth of weeds, mulch covering technology is widely used in the vast number of rural areas, farmers in order to improve economic benefits, change the mulch film 1 year for 1 year 2 times or more times.
Agricultural film plays a great role in the planting and growth of crops, and some manufacturers have also increased the production of agricultural film. However, when some agricultural film is produced, there will be wrinkles, what is the solution to this phenomenon?
1. The film thickness is uneven. In this regard, we can clean the impurities in the die mouth and wind coil, and adjust the thickness of the film to ensure that the thickness of the agricultural film is uniform and consistent.
2. The blowing ratio is too large, causing the membrane bubble to be unstable, swinging left and right, and easy to appear wrinkles. It can increase the speed of the external cooler, improve the cooling effect, reduce the membrane type, and ensure that the film can be fully cooled.
3. The pressure on both sides of the traction roller is inconsistent. The axis of each guide roller can be checked with a horizontal ruler so that it is in a horizontal position and parallel to each other.
4. The axis between the rollers is not parallel, which affects the stability and flattenability of the film, and wrinkles appear. Use a steel tape measure to measure the base of the insert plate, and adjust and align the insert plate.
