Advantages of technology
In compound material, no solvent residual, especially as to meet the requirements of modern health of food and pharmaceutical packaging.
In the production process there’s no volatile solvent emissions, no pollution to the atmospheric environment, excellent production environment.
Because they do not use the conventional drying system, therefore can significantly reduce energy consumption, low production cost.
Coating glue and total cost has certain decrease than existing technology.
Machine speed fast, small footprint, no fire and explosion risk.

The range of composite material and the requirement of surface tension
Solvent-free plastic- plastic laminating machine can be composite substrates are mainly
BOPP，PET，Nylon，CPP，PE，VMPET，VMCPP，PVC，paper,etc,base material is generally applied thickness in 7um-120um (According to the equipment).
The surface tension of the BOPP, PE, CPP, VMCPP general than 38 dyne;
PET film surface tension must be more than 48 dyne;
BOPA(NY)、PVDC and so on must up to 52 dyne.
