Rolls of pre-stretched cling film are used to manually wrap and unitize bulky loads such as boxes on a pallet. Using film that has previously been plastically stretched simplifies the wrapping operation. Unfortunately, however, the pre-stretched rolls of film have edges which are prone to fail during use. The disclosed invention concerns rolls of pre-stretched cling wrap having improved edges that are less prone to fail, and the method and apparatus for producing such rolls.
