Polyva takes you to understand the source of the PET film production process: protective film factory direct sales Release time: 2019-09-03 Click: 636 PET film production process: 1. First, the original PET film is sorted into a single product and enters the conveyor line, and then the material is discharged The device enters the mold. 2. Because the shape and outer diameter of the product are not uniform, there are high requirements for the accuracy of the sleeve labeling machine. At present, the dual positioning guide system that has appeared in the world can perfectly solve these problems and make the sleeve label pass rate Reached 99, 9%. 3. Use synchronous reclaiming device. The reclaiming is more stable. Automatic alarm and linkage control solve the problem of continuous operation of the machine when a failure occurs. 4. Due to the particularity of this type of product, it adopts electric heat shrinkage. However, electrothermal shrinkage is generally more difficult to control than steam shrinkage. There will be wrinkles, uneven heating of the vortex, etc. In addition, the outer diameter of the product is not uniform, and the size on the selection label is much larger than the conventional one. This brings great difficulty to shrinkage. However, this problem can be solved by adopting a rotary step-by-step contraction method. Foshan Bowei Environmental Protection Material Co., Ltd. is an electronic material supplier with 20 years of experience.
