The surface of the printed matter is covered with a thin transparent plastic film to form a paper-plastic print. The post-processing technology is called lamination, which is a kind of finishing method for printed surfaces. In booksellers or newspaper kiosks, books and magazines that we often see, the cover of small albums, and the outer packaging of some of the products in supermarkets have been coated and processed. The printed articles that have undergone the laminating process not only have a glossy surface, but also make the printed products bright and colorful, and also improve the tear-proof strength, water resistance, and corrosion resistance of the printed surface. Become an effective means to improve the quality of printed materials and commodities.
Films can be divided into two types, namely coating film and pre-coating film. The coating film can be divided into oily and water-based (including dry and wet) film. It can be divided into light film according to the film material. Matt film two. However, due to the pollution caused by some film processing processes and the difficulty of reusing the waste products, it was gradually eliminated. Therefore, since the development of the water-based laminating machine in the 1990s, the water-based laminating process has been promoted and applied. The water-based laminating film has been favored by customers because of its high brightness, high grade, easy recycling, and no pollution.
Water-based film adhesive with water as dispersant and high polymer as disperse phase white emulsion adhesive without any organic solvent. The residual organic monomer should be less than 0.1%. It smells odorless or slightly mellow. Or ester fragrance. Therefore, there is less pollution to the environment, so that the coating process achieves maximum environmental protection.
The water-based adhesive film has better glossiness and whiteness than the organic solvent-type film adhesive, and the adhesive force is also comparable to that of the solvent-type adhesive; and the water-based adhesive water-based machine coating adopts a cold-adhesion method without heating and drying, and can be used in a large amount. Save energy; Due to the high water-based gel solid content, the same kind of water-based adhesive than solvent gel coating area of ​​more than 50%, so the cost of water-based plastic film is much lower than the solvent glue.
Yutian County Shengtian Printing & Packaging Machinery Co., Ltd. as a Chinese post-press machinery manufacturer that has achieved certain achievements in the research and development of water-based laminating machines has promoted the development of domestic water-based laminating technology. The company has developed manual water-based laminating machines and web water-based laminating machines in accordance with market demand. Among them, the company's SF-1020 fully automatic water-based wet laminating machine and JSF-1020 water-based wet-type wet laminating machine won the State Economic and Trade Commission awarded the "National New Product" honor certificate.
SF-1020A fully automatic water-based laminating machine is the newly developed water-based wet laminating machine based on Yutian SF1020 automatic water-based laminating machine. The machine has no pollution, easy recycling, fast speed and low energy consumption. , high efficiency, easy operation and other characteristics for the domestic water wet laminating machine in the concept of environmental protection to fill a gap.
In addition, the JSF-1020A roll laminating machine was successfully developed after the HSF-1020A single-sheet paper laminator. It is not only suitable for roll paper lamination, but it is still suitable for sheet-fed lamination. The machine is very simple and convenient to operate, has two functions and is more applicable. The adhesive used is a water-soluble green glue, with good adhesion, high transparency, non-toxic and odorless, and can dissolve powder on the print surface without snow spots. The film does not need to be heated at high pressure, so the water laminator has a simple structure, low power consumption, high speed, and improves the working environment of workers. Because the water-based glue can dissolve the powder on the surface of the printed product, the film-covered product also has the characteristics of high brightness, high grade, easy recovery, and no pollution.
In China, water-based laminators rely entirely on imports before they have achieved local production. The introduction of the first water-based laminating machine has brought great benefits to Chinese printers with the advantages of reasonable cost performance and easy maintenance. With the development of economy, the emergence of water-based laminating machines has been widely used in the post-printing processing of book covers, small pictures, handbags, gift boxes, and wine boxes.
At present, although there are still some products in the water-based film coating process, such as snow spots, product bubbles, wrinkles of the film products, false bonding at the edges, product curl after slitting, weak bonding of the products, and black products And other process problems. However, we believe that with the rapid development of our country's industry, the level of printing equipment manufacturing in China will continue to increase and the quality of printing technicians will increase. The laminating process will embark on a more perfect and environmentally friendly road.
