Process for producing printable film

摘要

A process for producing a printable film comprises subjecting at least a first surface of a film web to a modified atmosphere dielectric barrier discharge (MADBD) treatment at a first location; winding the film web onto a reel; transporting the wound film web to a second location; unwinding the film web from the reel; and subjecting the first surface of the film to corona treatment. The corona treatment restores printability characteristics such as surface energy and relative atomic concentration of polar chemical species of the first surface which diminish with time following MADBD treatment, and so is preferably conducted just prior to printing. The film may be printed on and may be used for packaging or labelling.
