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.
