As early as 2016, with the "G20 Blue" and the fourth quarter of the environmental protection tide, many flexible packaging companies have repeatedly been forced to stop or to limit production due to environmental problems. Now that the first round of Central Government’s Environmental Protection Inspections has ended, the second round of inspection of the Central Ministry of Environmental Protection is coming soon! Environmental Protection Department declares that the national inspection will be strengthened, the relevant mechanisms and coordinated measures will be further improved and illegal business be forced to shut down and rectify for at least 3 months!

In the wave of environmental protection, how could flexible packaging industry across the country successfully pass the environmental inspection?

Responding to the wave of environmental protection enterprises preferred solvent-free laminating technology

It is reported that some domestic major flexible packaging and gravure printing companies have begun to recycle and treat VOCs with combustion or low temperature plasma measures. To date, most of the flexible packaging materials can be made from solvent-free adhesive. LeeMac introduced Smart SL-S8 solvent-free laminating machine.

Solvent-free laminating technology is the most environmentally friendly one in Europe and the United States and have occupied a very importance. After decades of development and application, this technology has been very mature. Solvent-free laminating technology, flexographic printing and coextrusion composite is considered as the three most important environmental protection technologies in international flexible packaging.

What is solvent-free laminating technology?

Solvent-free laminating is another laminating technology used in the flexible packaging industry relative to the dry solvent-based one. The solvent-free adhesive and special compounding equipment are adopted to make the film substrates stick together, which are adhered together after the chemical aging reaction of the adhesive.

What is the difference between solvent-free laminating and dry laminating

Solvent-free composite and the dry solvent-based one both adopt adhesive to produce composite film. The difference between the two types of technologies is that solvent-free laminating adhesive does not contain any solvent. Hence, the two substrates do not need to eliminate the solvent in the drying tunnel before bonding. Solvent-free laminating and dry laminating are practical industrialized production method that compete with and complement each other in the production of plastic film composite.

Features of LeeMac’s Smart SL-S8 solvent-free laminating machine

The typical configuration of the LeeMac Smart SL-S8 solvent-free laminator consists of two layoff devices, a winding device and a solvent-free adhesive coating recombining device. Its biggest feature is that drying tunnel is not needed and laminating is direct through a special coating device.

Compared with the traditional dry laminating, Smart SL-S8 solvent-free laminating machine has many advantages, including cost reduction, product quality improvement, environmental protection, production safety and stability. It is an advanced equipment, which is worth promoting and of great practical value.

Solvent-free laminating technology -Novel environmental technology in flexible packaging industry

As the solvent-free laminating technology does not contain solvents, it is in favor of environment protection and clean production, and to ensure that the laminating is free of contaminant on the packaging food and medicine. This new laminating technology is trending to significantly accelerate the developing rate.

The application of solvent-free laminating technology can reduce energy consumption, enhance production efficiency, improve product quality and reduce overall costs, which is beneficial to improve the market competitiveness of enterprises and respond to the Central Environmental Protection Inspector.
