Development trend of film lamination

The paper after the film lamination process is unrecoverable and becomes a white pollution, and toxic substances such as toluene and water are volatilized during the film coating process, which impairs people's health. Today, advocating "protecting the environment and protecting resources", the plastic film coating process has been eliminated in Europe and the United States, and European and American countries have even refused to import various packaging materials with plastic film. [ Thermal Lamination Machine ] Although there are water-based plastic film coating processes and hot-melt pre-coating film dry plastic compounding processes, the former still fails to solve the problem that the film printing waste cannot be degraded and cannot be recycled. The latter requires a large amount of heat in the production process and is discarded. The material needs to be separated in paper and plastic at 60 ° C, and the cost is high.



With the improvement of environmental awareness, new scientific and technological achievements will eliminate the old process products, so that the film process will undergo qualitative changes. "Non-toxic, harmless, green and environmentally friendly" naturally becomes an inevitable development trend of the film coating process. In addition, the glazing process is therefore optimistic. Glazing is a method of coating, spraying or printing to add a colorless transparent coating on the surface of the printed matter, that is, UV varnish. After calendering and drying, the gloss of the surface of the printed product is increased, and the stiffness is also improved. [ Thermal Laminator ] At the same time, the printed waste after glazing can be recycled or decomposed by itself, and does not pollute the environment. Therefore, glazing is a processing technology with great development potential, and it is possible to gradually occupy the plastic coating process market. Although the dilute machines used in oil glazing and alcohol glazing on the market are toluene and alcohol, respectively, which are harmful to the human body and unfavorable to environmental protection, water glazing has gradually become the mainstream of glazing process.[ Lamination Machine Manufacturer ] The water-based UV glazing process that has been developed so far is an ideal environmentally friendly glazing process and the development direction of glazing process in the future.
