Generally speaking, composite film has better transparency, mechanical strength, processing adaptability, gas density, heat resistance, cold resistance, waterproofing, etc. Food, product and consumer goods, etc., make it unable to deteriorate, not corrodes, and maintain the original quality and various forms. Traction, consisting of leading racks, human font boards, traction rollers, rolling mechanisms, and traction motors. Observe whether the thickness of the film is uniform, whether the folding diameter meets the standard, and whether the width of the film blows is deviated. With the in -depth development of the economy, people attach great importance to the environment, and various industries have carried out energy conservation and emission reduction models, and established environmentally friendly industries. The external cooling method is an early application method. Under the action of the cooling ring, the cooling air around the circular ring on the circular ring on the circular ring along the squeezing direction and the outer surface of the membrane bubbles is generated. Before the second start, the remaining shattered materials in the machine room should be removed to reduce the start of the start. The foam of the bubble pipe is irregularly due to unstable traction speed and the wind pressure of the cooling rings. The tension of the material is too large. Solution: Adjust the cooling device to ensure that the air outlet is uniform. Observe the plasticization of the film, and find that the crystal, stiffness, and water pattern are found in time.
