1. High precision alloy steel die head make sure the customer can get the best coating effection.

2. Total Machine is controlled by  PLC.Precision control coating speed and glue amount.

3. Increase the film function in some glue or substrate is not suitable for direct knife coating that realize 2 kinds of craftwork (knife coating and film coating.) on one machine.

Second, the length of the coating section changes, the spacing is unstable:

6. When the back roller and the coating roller are in contact with each other, the gap between the two ends is inconsistent and the pole piece is wrinkled. Regardless of whether the first side or the second side is applied, the gap should be carefully adjusted. First, the gap is appropriately enlarged, and then slowly reduced. At the same time, observe the dial scale of the coating roller just touching the foil strip, and then Reduce the gap by 0.03mm.
7. When the correction system is abnormal, the pole piece will be wrinkled. Check the three correction systems before and after the inspection, whether it is in the automatic state. If the lengths of the foil strips are inconsistent, that is, when the file is bent too much, the pole pieces will be wrinkled. Exceeding the correcting ability, the foil has to be replaced. 8. When the pole piece tension is too large, the pole piece is wrinkled. Check that the tension setting is reasonable. Then check each drive roller. The rotation of the take-up roll is flexible. Handle inflexible rollers in time.
9. When the back roller is in the inconsistent stroke, the pole piece is wrinkled. It is necessary for the mechanic to check. Confirm and adjust. After the back roller and the coating roller are pulled apart, the gap between the two sides is 1mm (see the dial indicator), and the test is started. When the tail is qualified, lock the nut.

10. The surface of the rubber roller on the back roller will undergo periodic elastic deformation during re-use. When a certain degree of deformation remains, wrinkles will occur. At this time, new products must be replaced.
11. The cause of looseness of a certain roller fastening screw causes the parallel state of each roller to be destroyed, and wrinkles may occur at this time. As long as it is found in time to adjust and tighten in time.

PET film--


PET film is a relatively comprehensive packaging film. It has good transparency and luster; it has good air tightness and aroma retention; it has moderate moisture resistance, and its moisture permeability decreases at low temperatures. PET film has excellent mechanical properties, its toughness is the best among all thermoplastics, tensile strength and impact strength are much higher than general film; and it has good strength and dimensional stability, suitable for secondary processing such as printing and paper bags. . The PET film also has excellent heat resistance, cold resistance, and good chemical resistance and oil resistance. However, it is not resistant to strong alkali; it is easy to carry static electricity, and there is no proper antistatic method. Therefore, attention should be paid when packaging powdery articles.

(1) PET high gloss film
In addition to the excellent physical and mechanical properties of ordinary polyester films, the film also has excellent optical properties such as good transparency, low haze and high gloss. It is mainly used for high-grade vacuum aluminum plating products. The film is mirror-coated after aluminum plating, which has good packaging decoration effect; it can also be used for laser laser anti-counterfeit base film. The high-bright BOPET film has a large market capacity, high added value and obvious economic benefits.
