Static eliminators are used in flexo printing, including induction type, high voltage corona discharge type and radioactive isotope type. Their principle of eliminating static electricity is the same. They all ionize various molecules in the air into ions. the air becomes an ion layer and a conductor of electricity. Part of the charged static charge is neutralized, and part of it is guided away by air ions.

flexo printing machine For plastic film printing, antistatic agents are generally used to eliminate static electricity. Antistatic agents are mainly some surfactants, whose molecules contain polar hydrophilic groups and non-polar lipophilic groups. The lipophilic groups have certain compatibility with plastics, and the hydrophilic groups can ionize or absorb water in the air.forming a thin conductive layer that can leak charges and thus play an antistatic role.
