Jumbo Roll Adhesive Tape Coating Machine

1.Main engine & pump full-automatic tracking system and constant tension control system, no matter ensure the coating stability, improve the material compound roughness.

2.Double position for taking up roller and full automatic not reduce changing roller, greatly improve the equipment operation and produce efficiency.

4. When the coating machine is running, the pole piece is broken.
1. The belt is not right, and the additional pulling force is increased to make the foil strip break in the weak place. 2. Sampling causes damage, resulting in a significant decrease in the tensile strength of the foil strip. 3. The tension is too large, unstable, and there is a sudden change. 4. The air volume is abrupt and the distribution is severely uneven.
5. The temperature is abrupt, which has a great influence on the strength of the aluminum foil. 6. The quality of the foil strip is poor and the edge is notched.
7. The foil strip is seriously deviated and is cut off by the edge of the roll end. V. Other failure phenomena:
1. There are obvious embossing marks and scratches on the pole piece, which are longitudinally distributed: 1) The blade of the scraper roller has a gap or sticks with foreign matter.
2) The coating roller is not easy to use. If the gap material on the coating roller is not scraped off and applied to the substrate again during the coating gap, it will leave obvious marks on the substrate;
3) The axis of the scraper device is out of line with the axis of the coating roller, causing the blade to be inconsistent with the pressure of the coating roller, the shape of the blade is not suitable, the blade elasticity is low, etc.
2. There are obvious cracks on the pole piece: the drying speed is too fast, the oven temperature is too high, and the baking time is too long.

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.
