How to Choose Laminating or UV Coating

2023-10-17

Today's printing plants and publishing houses pay much attention to UV technology and believe that UV coating can replace film laminating technology in book printing. In fact, this is just a wish of people. According to some printing plants applying UV coating technology, UV coating still has limitations in many aspects, and there are still many problems in process treatment, which cannot completely replace the film laminating process. First of all, from a purely environmental perspective, water and UV are in line with the trend. Because there are two layers of pollution, white pollution and plastic pollution. The cover after water-based coating and UV coating can be directly received without any further treatment.

 

In addition, from the perspective of the market application environment, in addition to food, medicine and cosmetics packaging, even electronic products that do not directly contact the human body are increasingly required to use the non polluting printing method of coating because the corporate culture advocates environmental protection and takes pride in it. With the economic exchange and cooperation between countries in Taiwan, a considerable number of printing and packaging enterprises in the coastal and inland areas have foreign business, while western countries have high requirements for environmental protection, and pollution-free water-based coating and UV coating have developed quite mature. Especially in food packaging, drug packaging and other fields, Europe has set strict standards, and there is very little room for non compliant coating and oily coating.

 

Nowadays, people's awareness of environmental protection is gradually enhanced, and relevant laws and regulations are constantly improved. The pollution generated in the process of film laminating and the difficulty in reusing film covered products when they are discarded are two major problems facing people. When it comes to film laminating, people often think of "white pollution". Many people in the industry doubt the function of the film laminating and whether it can continue to be used. In the future development process, the film laminating technology will accept more and more tests. How will mulching develop? Is it completely eliminated or rationally developed? These problems will become unavoidable problems in the development of film laminating technology.

 

Post press coating can enhance the light resistance of the ink, increase the ability of the ink layer to prevent heat and moisture, and play a role in protecting the impression, beautifying the product, and replacing the lamination film. coating is to beautify printed materials, protect printed materials, strengthen the publicity effect of printed materials and improve the practical value of printed materials. After polishing, the printed matter surface appears smoother, which makes the incident light produce uniform reflection and the ink layer more bright. Polish is the use of varnish on the surface of printed matter coating processing. After printing, take appropriate measures to protect the surface of paper or paperboard prints before final processing. The printed matter is coated with a layer of bright film after being polished. Printing coating is cheap and simple compared with film laminating. It can be full plate coating or partial coating. According to the actual situation, the cost of film laminating is higher than the cost of coating. In order to reduce costs, some magazines and books have adopted coating to decorate the covers. The film laminating speed of traditional film laminating machine is 30m/min~75m/min, and the current online coating equipment can fully match the speed of the printing machine, and the stability of the coating quality has been greatly improved. Without considering the specific requirements of customers, the coating process is more economical in terms of efficiency.

In a word, you can choose the appropriate laminating machine and uv coating machine according to your product, cost requirements and environmental requirements.
