In the converting industry, in paper and cardboard applications for coupling, our flame treaters allow to prepare the surface of the material in the best possible way before it is coupled with extruded PE, thus eliminating all surface impurities (hairs etc). You can also check the correct amount of moisture in the paper, thus avoiding excessive drying of the paper, which can generate dangerous surface breakage of the paper.
A further advantage in the use of flame treatment for paper, before the coupling with PE, is that of being able to considerably reduce the temperature of the extruded PE, and its specific quantity. If the treatment is used AFTER the process of coupling with extruded PE, the flame polarizes the surface layer of PE, and makes the surface ready to be re-coupled with any other successive layers or different materials.
In the case of aluminum foil, flame treatment allows to degrease and / or clean the surface from pollutants that can contaminate the surface after the production process.
