Use of natural gas (natural gas or liquefied petroleum gas) and to help with the help of a certain shape of flame thrower mixed combustion of high temperature flame to PP PE surface oxidation treatment, can greatly improve the surface tension of the plastic material, improve the printing ink adhesion molecules, prevent ink from falling out, flame treatment is polar plastic containers for surface treatment technology of printing quality stability is the most effective. It can be made into a flame processor independently, and it can also install the Automatic Screen Printing Machine to form the production line.
