People have been relying on flame treatment as the only way to print indications and calibrations on medical devices like medicine bottles, IV bags and syringe barrels. The traditional method of flame treatment includes exposing plastic devices to the flame in order to oxidize the surface of the device enough to stick labeling or print calibrations. Although flame treatment of medical devices was used on commercial scale, the issues inherent to this method of printing calibrations are countless.
This is the reason that corona treatment of medical devices has emerged as an alternative of flame treatment.
How is Corona Treatment better than Flame Treatment?
There is a high probability of surface deformation associated with flame treatment. Heat tolerance varies with the nature of the material to be treated. Although technicians know precise temperature settings for treating different kinds of materials, small variations in the flame intensity can deform the shape of the device. On the other hand, corona treatment of medical devices involves oxidization of material through high voltage therefore it has completely eliminated the risk of device deformation.
Another advantage of corona treatment is reduced health risks. Excessive exposure to high flame can cause serious skin infections and lungs diseases. Moreover, flame treatment is also dangerous to handle. Corona treatment is based on the generation of corona discharge through high voltage it allows technicians to easily handle complex geometries and delicate objects. Read more
