Brief introduction of steel plate coating technology

Steel plate lamination technology is a processing technology that puts plastic film and metal plate through high temperature hot pressing, and sticks the film on the metal plate. Film coating technology was born in Japan in 1977. It was originally used for can making, which can replace internal coating and external coating technology. Up to now, it has been developed into various fields such as building materials, interior and exterior decoration, home appliances, and automobiles. The lamination process does not use adhesives and solvents, so it does not contain formaldehyde, and the plastic film can be treated with decoration and anti-staining, which ensures the health of the human body and plays an environmental role at the same time.
The laminated sheet used in the canning industry, commonly known as laminated steel (Laminated Steel), is made of PP film and tinplate. The inside of traditional metal cans must be painted, and the substances contained in the coating method will have harmful effects on the human body and the environment, especially edible cans. The current treatment method is to use resin to coat the inner wall of the can . However, because the paint used in this coating process contains environmentally harmful substances-bisphenol A (Bis-phenol A) substances, which are internationally recognized environmental hazards, and there may be a problem of dissolution. Exceeding the standard will have a bad impact on the human body. And the serious consequences caused by this problem have attracted attention both at home and abroad.
The birth of steel plate coating technology is a progress in the production of metal cans. With its wide application, the traditional metal can production process and technology will be subverted, and productivity, production cost, cleanliness, environmental protection and other aspects will also take a big step forward.
