Abstract
A carrier film composed of an ultra high molecular weight high density polyethylene is disclosed herein. The carrier film has a pair of opposed surfaces and a pair of opposed edges. The carrier film is perforated with a plurality of circular apertures. One of the opposed surfaces of the carrier film is roughened to carry a plurality of tobacco leaves to a wrapping machine. Tobacco leaves are held on the carrier strip by a vacuum and wound and stored on a spool. After a selected aging period the carrier strip is unwound from the spool and the tobacco leaves and carrier strip are sprayed with an adhesive. The carrier strip then releases the tobacco leaves adjacent a wrapping machine and is washed, dried and cooled.
