Abstract
This invention concerns a process for producing a printable film comprising: providing a web of film; at a first location subjecting at least a first surface of the film web to a modified atmosphere dielectric barrier discharge (MADBD) treatment; 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 invention also concerns printed films obtainable by the process of the invention, and articles of packaging and/or labeling made from such films.
Claims21
A process for producing a printable film, comprising the sequential steps of:
- a) providing a web of film;
- b) at a first location subjecting at least a first surface of the film web to a modified atmosphere dielectric barrier discharge (MADBD) treatment;
- c) winding the film web onto a reel;
- d) transporting the wound film web to a second location;
- e) unwinding the film web from the reel;
- and
- f) subjecting the first surface of the film to corona treatment, wherein the corona treatment takes place in air and the MADBD treatment takes place in a gas atmosphere other than air.
