With the continuous development of social and economic flexible plastic packaging is widely used in the field of food, medicine and other daily consumer goods. However, due to the limitations of the performance of various single-layer materials, it is usually necessary to laminate a variety of materials to meet the needs of various packaging products. The initial dry lamination process, due to its inherent defects, uses a large amount of organic solvents in the production process, which is hazardous to the health of the workers. The residual organic solvents in the packaging film have a serious impact on the health of consumers when they come into contact with the contents of food and drugs.
The state is paying more and more attention to the safety supervision of food and medicine. Dry lamination process will eventually face elimination due to its inherent defects. Must be healthy, safe, environmentally friendly solvent-free laminating process instead. Compared with the ordinary dry laminating process, domain first technology solvent-free laminating machine has the following advantages.

First, health
Flexible plastic packaging solvent residue is the main problem affecting the health of consumers, operators, some technicians in the industry from the equipment, raw materials and other aspects of a lot of technological improvements, but can only reduce the amount of solvent residue, can not completely avoid the generation of solvent residue. Solvent-free process in the production process to avoid the use of organic solvents, solvent residues in the fundamental solution to the problem. Therefore, solvent-free composite is a healthy composite process.

Second, safety
Domestic and foreign flexible packaging production enterprises fire and explosion occurs from time to time, mainly due to improper operation or high concentration of organic solvents in the air. If the use of solvent-free lamination of the chemical completely avoid the use of organic solvents, eliminating potential safety hazards.

Third, environmental protection
Solvent-free laminating adhesive is completely solid, does not contain any organic solvents. Therefore, there is no impact on the health of production workers, but also to achieve zero emission of organic solvents, to avoid air pollution. Has obvious environmental advantages.

Cost savings
1. Solvent-free composite coating amount is usually 1.3-1.8g/m2, while the dry composite in 2.5-4g/m2, so compared with the dry composite, adhesive consumption can save about 50%. Although the solvent-free glue is sold at a higher price, but after calculation, the overall raw material cost can still be reduced by about 20%.
2. As solvent-free laminating process does not require drying process, it effectively reduces the cost of energy consumption. After calculation, the energy cost of solvent-free equipment is 1/15 of the energy cost of dry laminating equipment.
3. From the point of view of production efficiency, the efficiency of solvent-free equipment is 1.5-2 times of the ordinary dry laminating efficiency, which effectively reduces the production cost.
