1. Requires good printability of inks Due to the increasing demand of manufacturers for the advertising role of the carton, the design of the carton pattern is getting more and more exquisite, so a large number of screen adjustments, color registrations, and large field printings are used. Some patterns have been fine to 5% of shallow mesh transitions. For on-site layout, it requires full color and uniform ink. At present, China's market is widely used or oily gravure ink. The performance of water-based gravure inks is not good enough for printability. It is also difficult to meet the requirements of carton customers.
2. Requirements ink meets environmental protection requirements Although China is still using a lot of oil-based gravure inks with lower environmental factor in carton pre-printing. However, alcohol-soluble, benzene-free inks that meet environmental requirements have gradually become mainstream. Major printing companies and ink production plants have also conducted useful explorations of the promotion of water-based inks. In addition to solvent environmental protection requirements. For heavy metals in ink. Toxic substances, carcinogen content also put forward strict requirements. Such as the dry film of the ink heavy metal content restrictions. Internationally accepted standards are EU-EN-71 and US-ASTM-F963-96a.
3 requirements of ink with heat and friction resistance corrugated board production line compaction drying channel length 2O ~ 100m. Drying temperature is 17O ~ 200 °C. Printing surface at high pressure. The time to drag 20-1OOm under high temperature conditions is about 10 seconds. This requires that the ink and varnish must have excellent heat and abrasion resistance. If the ink and varnish selected resin is not heat-resistant and wear-resistant. Softening occurred. Stickiness or ink discoloration and hair growth can lead to waste products.
4. Require that the ink layer has a suitable surface friction coefficient. The manufacturer's inspection method is: Place the filled cartons horizontally on an active board surface. Then increase the end of the board with a certain linear speed. When the angle of the fixed end is less than or equal to 24°, the carton cannot slide. When the angle of the fixed end is greater than or equal to 30°, the carton must be slid, and it can slide or be stationary in a range of more than 24° and less than 3O°. It is not difficult to just wear the ink layer. This can be achieved by adding a lot of wear-resistant additives to the ink. However, requiring the surface of the carton to have a suitable coefficient of friction is quite difficult for the ink manufacturing industry. Cartons gravure preprint required for a variety of equipment, inks, Varnish have been made. Demax Ink Chemical Co., Ltd. looks forward to working with more carton manufacturers. Bigger, stronger paper box preprinted this market. To achieve everyone's win-win situation.
