Improve uv ink to plastic surface adhesion in three ways.Since the uv ink is

printed in terms of surface attachment rather than by oxidation or penetration,

the amount of surface tension is very important. And because the plastic surface

is non-polar and insoluble interface, even the solvent type ink is difficult to adhere to.

In addition, because additives in plastic often surface, they can not actually connect.

Plastic surface treatment can be divided into three ways: Halo treatment is a method

to improve the uv ink adhesion through electric shock treatment. Halo device of

Second, the base treatment is used as a medium between the ink and the printed

material by a thin film, and it is normally used for materials without corona treatment,

such as PP. Its processing mode is divided into on-machine line PRIMER and offline

PRIMER processing. The thickness of this film and printing smoothly or not has a great

relationship, too thick is easy to cause waste, too thin is easy to cause printing failure.

Third, the flame treatment is carried out in the way of flame, generally suitable for

irregular shape or high speed (1000 m / minute) of the adhesive film treatment,

generally used in the bumper, blowing molding table.
