Low surface energy in plastic materials challenges you in bonding, coating and printing processes. Durability and quality are important factors in manufacturing medical devices and an efficient surface treatment is required to optimize these processes. Corona Treatment modifies the chemical structure in the surface of plastic materials and improves surface tension. The result is uniform treatment and improved adhesion and wettability properties with long durability and the possibility to achieve high quality results in bonding, coating and printing Eltech corona treatment system is specially design for treatment inside the PP caps & silicone sheet, The compact design of the unit allows it to be taken to a customer and to perform tests on site. We have developed corona treatment system for PP caps & Silicone for bonding each other, corona treatment works effectively producing high surface dyne level.
