Abstract: A plastic film cutter for clamping to an upstanding edge of a carton housing a supply of plastic film. The film is pulled across the top of an elongated cutter body which has a groove to guide a sliding cutter. The lower portion of the cutter has a plurality of inverted "U" shaped clamps for fitting over the carton edge. At least one of the clamps has a projection on its inner surface to prevent the cutter from being used on cartons for which it is not intended, that is, cartons which do not have a corresponding cutout to receive the projection.

Abstract: Package of a plurality of unitized film rolls of polymeric wrapping film. Each roll is suspended on its core within the bulk package so as to be separate from each other film roll in the package, and so as to be physically spaced from confronting surfaces of the package. The film on each film roll is thus available to the customer free from distortion, abrasion and edge damage.
