1. In order to solve the problem that the inflation ratio of the product is too large, the film bubble is unstable, swings back and forth, and is prone to wrinkles, so it is necessary to properly reduce the inflation ratio of the air bubble film machine.
2. The extrusion temperature is low and the plasticization of the resin is poor, resulting in poor transparency of the film after blown by the bubble film machine. The solution is to appropriately increase the extrusion temperature so that the resin can be evenly plasticized.
3. Adjust the cooling device to ensure that the air volume of the air outlet is uniform, which can make the thickness of the film uniform. Therefore, when the air volume around the cooling air ring is inconsistent, resulting in uneven cooling effect, it needs to be adjusted.
