Hot melt adhesive is a malleable thermoplastic adhesive that changes from solid to liquid when heated, and can be used for bonding in clothing, bookbinding and packaging.
Coating method
The film coating machine can be used in the film coating process of traceless hot melt adhesive. The following is a possible film production method:
Prepare the non-marking hot melt adhesive and heat it to the proper temperature to make it coatable.
Place the substrate to be coated on the coating plate and fix it on the coating plate.
Place the applicator head on one end of the substrate, and then bring the applicator head into contact with the applicator plate.
Select the appropriate coating speed and pressure according to the needs, start the Film Applicator and start coating.
After coating, the coated substrate is placed in a drying room to dry.
For some non-marking hot-melt adhesive films that require special treatment, such as anti-static, waterproof, etc., corresponding post-treatment processes are also required.
NBCHAO reminds you: when coating non-marking hot melt adhesive, it is necessary to ensure the cleanliness and flatness of the surface of the coating head and coating plate to ensure the uniformity and quality of the film. In addition, it is also necessary to set reasonable coating parameters according to the characteristics and requirements of the non-marking hot melt adhesive used to obtain better coating effects. After the coating is finished, it is necessary to clean the coating head and the coating plate in time to ensure the long-term stable operation of the coating equipment.
