ABSTRACT:
Two or more chemically dissimilar and non-compatible films may be bonded together to form a composite sheet by simultaneously subjecting them to high voltage electric corona discharge of selected intensity continuously through a critical region of mutual contact of the films. The critical region begins at the point at which the film surfaces to be bonded are not in contact with one another and extends at least to the point where all the films to be bonded are in mutual contact with their adjacent films.
A preferred film suitable for use as a wrapping material and obtained by the process of the invention comprises at least one layer of a polyolefin film and at least one layer of a film containing an acrylonitrile polymer.
