Characteristics of instant coated products
(1) It is prone to foaming and film detachment. In large-area solid printing or high humidity working environment, foaming and film removal are particularly serious.
(2) The surface of the product often produces bright spots or fog points with different gloss.
(3) The product is prone to curling. If the pressure is too high when the glue is applied or the temperature is too high during drying, 【 Manual Lamination Machine 】 the curling phenomenon is more serious.
(4) Chemical substances such as organic solvents will volatilize into the atmosphere during filming, causing environmental pollution and even causing fires.
Characteristics of pre-coated film products
(1) The film-forming product using the molten pre-coating film does not exhibit foaming and film peeling, and the product has a long service life.
(2) The film-coated product using the solvent-evaporable pre-coating film may have a large thickness in the printing ink layer, where the folding, die-cutting, and indentation pressures are relatively large, or in a high-temperature environment, the film may be released and foamed. phenomenon.
(3) The solvent-evaporable pre-coating film easily adheres to impurities such as dust during production, 【Film Lamination Machine 】thereby affecting the surface effect of the film-coated product.
(4) The film product is basically free from curling.
It can be seen from the above that the pre-coating film coating process, especially the molten pre-coating film coating process has the advantage that the coating film coating process cannot match, and is an inevitable choice for the future film coating industry.
