In the 1990s, there was speculation in the printing industry that according to the requirements of environmental protection, 15 percent of China's laminated products would be replaced by glazing after 15 years. Because from an environmental point of view, there are two layers of laminating pollution, white pollution and plastic film pollution. Although water lamination and UV lamination now occur, BOPP film and paper are still stuck together and paper recycling is impossible. Waterborne gloss and UV
The cover after glazing can be recycled without any further processing. About the postpress expert has analyzed: "Now 80% of China's papermaking cellulose source is relying on the recycling of used newspapers, including paper edge, paper hair. If we use a large number of film materials, then the used paper, including cutting The paper edge, paper hair, etc. cannot be recovered, which will bring incalculable losses to the country. This is actually destroying resources. In the investigation of the towel, we also discovered that some units have cut the edges of Because the paper is not recovered by the paper mill and cannot be processed, a self-made stove is used to burn these cut edges along with the edges of the uncoated film, which not only causes waste of resources, but also causes a second environmental pollution. ."
Abroad, due to environmental protection claims to glazing
The commonly used glazing methods are oily glazing, waterborne glazing, and UV glazing. From an environmental perspective, waterborne glazing and UV glazing are in line with trends. Some foreign countries have high requirements for environmental protection, non-polluting water-based coating and UV
The glazing has grown quite mature. Especially in the fields of food packaging, pharmaceutical packaging and other fields, foreign orders have established strict standards. The survival space for non-standardized laminating and oily coating has been very small.
Some professionals in the country have also received the task of the General Administration of Press and Publication to begin research on UV glazing. At the time, this technology was still in the north, according to researchers, UV
The main reason for the glazing was that printers from Hong Kong and Taiwan raised their overseas lives to Beijing. Beijing Baodao Packaging & Printing Co., Ltd. was one of the earliest companies to eat crabs. It was a job of printing Motorola. It is because foreign customers need UV glazing technology to make it popular.
The owner of a printing house in Beijing deeply felt the escalating trend of glazing. The factory mainly undertakes the packaging of products used for export. A few years ago, Samsung’s work at the factory was changed from film to glazing. In foreign countries, besides food, medicine, and cosmetics packaging, even those electronic products that do not come into direct contact with the human body, because corporate culture promotes environmental protection and is proud of it, it also requires the use of glazing as a non-pollution printing method.
Domestic, national conditions determine the film market
In China, the quoting price of glazing is generally not more than half of that of lamination. For the sake of reducing the cost, some magazines and books have used glazing to decorate the cover. However, the overall situation is not optimistic. According to the person in charge of a publishing house in Beijing, 99% of the company’s book cover is still laminated, although it is also known that laminating paper is difficult to recycle and is not environmentally friendly, but unfortunately people have already accepted the lamination process as the first choice for cover design. Program. Accumulation is hard to come back. This inertial thinking has changed from day to day.
There is still not much improvement in packaging. For example, the products of alcoholic drinks, the packaging sold abroad by the same manufacturer is glazing, and the products sold in China are laminated. In analysing this situation, professionals pointed out that the government should strengthen the formulation of environmental standards for printing and packaging products. For the reasons for this phenomenon, relevant professionals also provided a very fresh saying: Most of the general consumer groups in China favor bright colors and highly reflective effects. They think that such packaging is of a high grade, and Westerners usually accept it. Elegant gray tone. In China, this regional cultural difference has made Fumo more market-oriented in aesthetic terms.
Another reason is that the use of inferior materials has misled people into understanding light. In the case of UV varnish, one of its constituent photoinitiators has poor raw materials or the production process is not in place. After glazing, they leave irritating odors and yellowish prints, so people do not feel the environmental advantages of glazing. The real high-quality varnish has almost no odor after polishing, waiting until the die-cutting and other subsequent processes begin to smell. In some countries abroad, mature high-grade UV varnish has been widely used in cigarette packets and other fields.
In addition, high-quality varnish has advantages in the post-press processing stage, such as Cromm's UV varnish. One of the most important features compared to other brands is the stable performance of bronzing, which makes it popular in high-end packaging. . In the survey, we also found that the domestic cigarette factories, such as the Yunnan Hongta, are widely used foreign high-grade coating materials.
The issue of packaging and printing is related to the national economy and the people's livelihood. With the regulation of the market, the state will gradually attach importance to the issue of environmental protection in the printing industry. The potential of glazing will be even greater. However, due to the increase in the thickness and toughness of the paper and its good water resistance, the film will not completely fade out of the market. The fight between the two will continue to be staged.
