Promising green packaging printing paper The four pillar materials of modern packaging and printing - paper, plastic, metal, glass materials, of which paper has the fastest growth rate, the paper is the cheapest price, the raw material source is wide, and unlike plastic, it is not easy to dissolve, not as fragile as glass. Not as heavy as metal, easy to carry. In addition, paper products are prone to decay, which can recycle recycled paper or plant fertilizer, reduce air pollution and purify the environment. This paper packaging is considered to be one of the most promising green packaging printing materials compared with plastic, metal and glass.
Green packaging printing paper bag Donghua Paper Co., Ltd. and Tianjin Daxing Special Paper Research Institute jointly produced a new type of environmentally-friendly, high-strength embedding green packaging printing bag paper in Donggong. The product is made of waste paper as the basic material of the paper. At the same time of continuous operation, the water-soluble yarn is once formed into a high-strength embedded green packaging printing bag paper. In the production process, no pulping, acid, alkali and waste liquid are eliminated. The green packaging project is realized by using renewable resources, and the white pollution problem in environmental protection is also effectively solved. As a high-strength embedded group, the green packaging printed products have good bursting resistance, moisture resistance and anti-counterfeiting. The water soluble yarn in the intermediate grade can be dissolved in water at 95 ° C and can be recycled. Tested by the National Packaging and Printing Quality Supervision and Inspection Center, all products have reached the standards of superior products, and have obtained technical recognition from Japan, South Korea and other countries and regions.
Paper mold The paper mold is produced by solving the problem of foam plastic pollution, and is an emerging environmental protection industry. Due to the increasingly serious "white pollution" caused by foamed plastics, and the difficulty in waste disposal and high recycling costs, developed countries have banned production, sales, import and use. After years of trial and error, paper molded products have become the best alternative. The product can be similar to plants in a circulating environment and decomposes by itself. It has its unique geometry, shockproof and impact resistance, as well as antistatic and paper structure itself, equivalent or better than foamed plastic in force value test. Paper mold products have grown from the original egg tray to thousands of packaging and printing varieties. The progress of the basic equipment and technology shows a strong vitality. Nowadays, paper-based packaging is widely used in coastal developed areas, which reduces costs and enhances competitiveness for enterprises. Establishing a corporate image and providing new development prospects.
Transfer metal card Vacuum aluminum paper (commonly known as aluminum paper in the South), filter paper, vapor deposition paper, etc., is a green material in the packaging
printing industry that is increasingly used internationally. Due to its noble and beautiful metal texture, relatively low material cost, continuous packaging flexibility, stable and reliable printing performance and degradable, environmentally friendly properties, it is more and more popular.
Compared with traditional gold card paper, the vacuum sprayed aluminum transfer paper has the following advantages: the auxiliary materials used in the production of aluminum spray paper are odorless, non-toxic and meet the requirements of food hygiene. It can be widely used in the exquisite packaging and printing of tobacco, wine, tea, food and other products, such as good cleanliness, high smoothness, bright color, beautiful appearance, excellent printing performance and mechanical processing performance, suitable for gravure and embossing. ,
offset printing , flexographic printing, screen printing, etc., can also be embossed, die-cut, or even concave and convex; degradation and recovery performance, easy to handle and recycle, meet environmental requirements, is an essential material for export products.
Plastic film gravure aqueous ink Plastic film gravure water-based ink is an environmentally friendly liquid ink made of water as a solvent. It has non-combustible, non-explosive, non-toxic, non-irritating, stable ink, bright colors, high gloss, non-corrosive printing plates, easy to operate, and printing. Low cost, good adhesion after printing, strong water resistance and rapid drying. Products printed with water-based inks are completely non-toxic, environmentally friendly, and reduce the emission of organic volatile VOCs into the atmosphere. Water-based ink is the only non-toxic ink approved by the American Food and Drug Association.
Beijing Yingkefan Chemical Products Co., Ltd. conducted a water-based ink gravure plastic film printing test in March-April 2007 in a color printing and packaging factory in Xiong County, Hebei Province.
Water-based ink gravure plastic film printing case 1: gravure printing machine, electro-engraving plate, plate depth 45μm, printing speed 40m / min, drying temperature 60 ~ 70 ° C, printing materials: BOPP film, BOPP matte film and low-pressure HDPE film, ink Variety: WE-0824 in yellow ink.
Water-based ink gravure plastic film printing case 2: gravure printing machine, electro-engraving plate, plate depth 45 microns, printing speed 60 m / min (water-based ink gravure plastic film printing can be printed without revision. Such as light printing, plate depth 15 ～25μm, printing speed can be increased to 100m/min or higher), drying temperature is 60~65°C, printing material: BOPP film, film is printed after printing. Ink type: yellow ink in WE-0824.
Although the above products are basically just put into the market stage, the above printing cases show that the plastic film gravure aqueous ink has matured in color performance, printability on a printing machine, drying and acid resistance, alkali resistance and alcohol resistance. Problems that arise in printing can also be solved by proper adjustment of the ink. The biggest problem now is the adhesion problem. With the ink formulation and the improved surface treatment of the film, the adhesion problem will definitely improve in the near future.
According to a special research report of the US Freedonid Group Consulting Company, in 2006, the US packaging market Yangzhong, plastic consumption will exceed paper in 17 sub-markets, a total consumption of 4.9 million tons, and an average annual growth rate of 1.6% between 2001 and 2006. Plastic packaging is easy to process, and the production line speed increases its competitiveness. Secondly, rigid plastic containers, stand-up plastic bags, plastic bottles in the soft drink market, and fast
food packaging and retail market packaging bags grew strongly. There are indications that plastic film is growing at a high rate, and among these growth, food, medicine, vegetables, and fruits are the fastest growing. In these packages, special attention should be paid to food safety and environmental protection. In packaging and printing, attention should be paid to ink. Environmentally friendly water-based inks are the development direction of plastic film printing inks. The market prospect is quite broad, especially in China's ink manufacturing industry. In the case of plastic film gravure water-based ink is a good catch-up opportunity. At the same time, for the growing foreign trade, the ink can enable many companies to cross many foreign trade barriers to make Chinese products enter the foreign market smoothly.
