With the improvement of people's quality of life, people's awareness of environmental protection is also growing. "Non-toxic, harmless, green" has become the inevitable trend of development of all walks of life. In the printing and packaging industry, due to the coating process can significantly increase the intensity of printed matter, improve its waterproof performance, outstanding three-dimensional and other advantages have been favored by the industry. However, in recent years, the coating process itself is experiencing a qualitative change.

Over the years, the industry have adopted solvent-based plastic coated plastic film on the printing process, in order to protect and decorate the surface. However, this coating process is being criticized by all parties:

First of all, there are a lot of benzene and alcoholic chemicals in the solvent-coated plastic laminates and their diluents, which have strong volatility and toxicity, which will cause harm to the operators' health. It is estimated that each use of 1 ton of glue will be about 1.6 tons of toluene emissions to the atmosphere, only the printing and processing enterprises in Shenzhen City, the annual use of plastic covered about 10,000 tons, there will be 16,000 tons of toluene emissions to the atmosphere, serious pollution The environment, endangering people's health. In addition, these chemicals are flammable, in case of open flames or light flammable, causing a great risk to the production of fire.

At the same time, due to the use of solvent-based plastic film adhesive and its diluent benzene, alcohol substances in a short period of time can not be completely volatile, so that harmful substances along with the goods passed to the hands of consumers, threatening the living environment and the consumer Health, involving food, tea, tobacco, cosmetics, toothpaste boxes and other packaging products, the harm is more direct and serious.

Therefore, to adapt to the "energy saving" trend, solvent-based plastic film adhesive will be gradually replaced by water-based plastic film. Water-based plastic film can increase the surface gloss, strength, enhance the aesthetic effect, temperature, water, wear-resistant, can greatly improve the print grade and product value. At the same time, water-based plastic film adhesive solvent-free during the use of volatile, safe, environmentally friendly, does not cause harm to the health of production personnel, had a huge social benefits. At the same time, the development of water-based laminating machine has come out, but also make the water-based coating process has been vigorously promote the application. According to the customer, the use of water-based plastic laminating film processing, the overall cost down 20% -30%, with good economic benefits.

Water-based coating process has just been promoted, due to customers do not know much about this process, more concerns, afraid of problems, in view of this, our company has done a large number of tests for customers, such as: Xinhua printing plant in Hunan Province, to test the water-based printing Film after the temperature, humidity, oil and other properties, in the early stages of the machine to do the relevant film test, regardless of temperature, humidity, oil, can reach the coating product requirements.
