Rainbow aluminum coated cardboard production technology problem was overcome

At present, due to the complexity of the rainbow aluminum-plated cardboard production process, the first process has high technical content, the process is difficult, the domestically-made wide-width laser rainbow version is lacking, and the laser rainbow aluminum plating film is yet to be imported, resulting in rainbow aluminum-plated paper jams. When printing cigarette packs and barrels, it is prone to problems such as ink burst, poor refractive index, and so on, becoming a bottleneck for rainbow aluminum coated cardboard instead of coated rainbow cardboard.
Shenzhen Jinjia Color Printing Co., Ltd. adopts transfer, compounding, and nine color sequence connection UV gravure printing equipment, starting from the unwinding and transfer of white card paper, unwinding of composite film, adhesive bonding, drying, peeling and cooling, and transferring the rainbow card. Paper production, printing, and cutting are performed in one go. Strict controls are applied to every small part of the process. Eliminating changes in the environment's temperature and humidity make the paper prone to flounces, paper wings, etc., or material varnish before printing. Mismatches with printing ink resin systems can cause problems such as miscibility, poor abrasion resistance, and ink explosion.
