Solventless lamination is a method of compositing two or more substrates by using a solvent-free adhesive. The solventless lamination machine is mainly composed of two major parts including the solventless laminator and adhesive mixer. It mainly completes the operation of the unwinding, tension control, glue, composite and rewind. The adhesive mixer is a special device for quantifying the adhesive to the host. Here, we mainly introduce the types of solventless laminating machines.
Single Station Solventless Lamination Machine
Today, the single station solventless machine is widely used, which is determined by a variety of factors.
1. Due to the low initial adhesion of the solvent, the tension control requirements of the substrate are high. Therefore, during the solvent-free composite, the single-station solventless lamination machine has the advantages of shorter material feeding, high accuracy tension control and low waste rate.
2. Since the solvent-free adhesive has a certain opening time, it does not require a dry composite high-temperature drying system, using a single station solventless laminating machine, can realize the operation of the roll change during the downtime.
3. the manufacturing of the single station solventless laminator is relatively simple, and the cost is low. Moreover, the single station solvent-free lamination machine is compact, covering a small area, and one person can operate in general.
Overall, most of the solventless lamination machines, are the single station model, accounting for more than 70%.
Double Station Solventless Lamination Machine
The double-station solvent-free lamination machine is installed on an unwinding rack with two material rolls and can realize the reel alternation without downtime.
