Insulating Adhesive Tape Coating

Insulating Adhesive Tape Coating

It is suitable for manufacturing hot stamping film, laser film, gold and silver paperboard which need coating and laminating. 
 

Insulating Adhesive Tape Coating

Characteristics of several coating methods -

1. Characteristics of air knife coating process:
The advantage of air knife coating is that a thick coating amount can be obtained, the coating layer is relatively uniform, and paper breakage is less likely to occur during coating. The disadvantage is that since the coater of the coater is an invisible air knife, it is necessary to require the paint to be soft and easy to control in order to scrape off excess paint and smooth the coating. In addition, the air knife formed by the air jet is more likely to cause the splash phenomenon of the paint, and the splash of the paint easily causes partial clogging of the air knife gap, resulting in unevenness of the coating layer.

Scraper coating:
advantage:
1. Can make the paper get higher smoothness and gloss
2. The operability is higher than the air knife and the measuring rod, and the adjustment precision is higher than the latter two.
Disadvantages:
1. High requirements for base paper (to have good flatness, smoothness, sizing degree, etc.)
2. If it is used for topcoating, it also has higher requirements for lining (lower macroscopic roughness, but with appropriate micro-roughness)
3. This performance is good without air knives and measuring rods.
4. Easy to scratch the knife.

Characteristics of several coating methods -

Coating technology
Coating technology is widely used in the coating and composite packaging of substrates such as paper and film. At present, many domestic printing and packaging machinery enterprises use coating composite equipment, and their coating types and scraping methods are relatively simple, and the application of coating technology is also greatly limited. Regardless of the coating composite equipment, the key part is the coating head, and the coating method of the coating head directly affects the quality and effect of the coating.

Glue coating type and application
Coating compound equipment is mainly used for sizing coating and composite processing of various reel substrates such as plastic film, paper, electrochemical aluminum, cloth and leather. It is widely used in various packaging fields and has broad development prospects. The coating composite equipment is roughly coated with a splitting roller, an anilox coating, and a hot melt adhesive.
