Special technological requirements in the process of printing aluminum-coated cardboard

At present, some high-end products in the packaging market are commonly used in rainbow aluminum coated paperboard and aluminum foil gold and silver paperboard. As a result, the number of enterprises producing this type of paper is increasing day by day. However, due to some special technological requirements, some companies produce products that have some quality problems. For this reason, Turning the quality of a good product into the key to the sales of this packaging paperboard.

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 hard pack boxes and barrels of cigarettes, the phenomenon of ink burst and poor refraction is easy to occur, which becomes the bottleneck of rainbow aluminum-plated cardboard instead of coated rainbow cardboard. In this regard, Shenzhen Jinjia Color Printing Co., Ltd. has undertaken the task of this technology.

They use transfer compounding and nine color-sequential uV gravure printing equipment to start, transfer and unwind the white cardboard, unwind, laminate, dry, peel and cool the composite film. The rainbow-transferred cardboard is produced and printed. Cutting at one go, strict control on each small part of the process, eliminating the change in the environment due to temperature and humidity, so that the paper before the emergence of unprinted flounces, paper Alice and other shrinkage phenomenon. Or the problems of miscibility, poor wear resistance, and black explosion caused by the mismatch between the material surface varnish and the printing ink resin system, thus achieving the full quality control of the rainbow aluminum plated printing product, and solving the technical application problems of the material.

Zhongshan Evergreen Packaging Industry Co., Ltd. has recently introduced the world's high-quality cardboard composite equipment selection of imported raw materials, production of reel or single aluminum foil gold and silver cardboard, gold-plated aluminum paper cardboard, mirror gold and silver cardboard, pearl card Paper, frosted gold and silver cardboard, laser anti-counterfeit cardboard, a total of six series of various specifications, the annual output reached 6,000 tons, mainly used for food, tobacco, alcohol, medicine, cosmetics, clothing, home appliances, toys, crafts, gifts, etc. High-end packaging.

At the same time, gold and silver paperboard post-processing adaptability is good, especially suitable for offset printing, gravure printing, flexo printing, screen printing, embossing and other printing processes, as well as making boxes, pasting boxes, high-speed automatic packaging machines and other post-process processing.
