The solventless machine adopts a method that can composite two or more substrates by using solvent-free adhesives. The solventless composite process begins in Germany in the 1970s. The solventless laminating machine has a wide application with the advantages of environmental, hygiene, and high efficiency, especially used for the packaging industry of the food and the drug.
Development Of Solventless Laminating Machine
In 1974, the German company adopts the single component solventless-free adhesive in industrial production, marking the formal promotion of solvent-free composite.
In the 1980s, there was rapid development in developed countries such as Europe and the United States.
At the end of the 1990s, Japan gradually began to play an important to no solvent composite and had a great development. In India, Russia, Brazil, the solventless composite has gradually become the leading composite process.
In 1985, China had introduced the production technology and equipment of the solvent-free polyurethane adhesive from Germany, thereby enters the era of solventless composite process.

Mainly Solventless Laminating Machine Types Of Sinstar
Now Sinstar has several series of solventless laminating machines, including the series of WRJSi9, WRJi9, WRJFi9, SIL90, WRJSLi5, C180, E280, S380. Compared with the single station solventless laminating machine, the double station type mainly has the following advantages.
On June 8, 2021, Sinstar has launched a new product - three-layer solventless laminator and machine model is WRJSi9.
Three-layer composite machines, as the name implies is a solventless machine realizing one-time composite forming of three-layer materials. In recent years, there is a high-speed development for solventless composite, and the requirements for composite process and equipment functions are increasing. The solventless lamination equipment which can carry out the substrates compounding of multi-layer materials on a composite machine, is in urgent need.
Sinstar three-layer solventless machine has a reasonable structural layout, simple loading, saving time and effort, realizing one-time molding for three-layer composite, which is beneficial to improve production efficiency and product quality.
