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.

A package for a plurality of rolls of polymeric wrapping film, said package being designed so that no part of the package is in contact with the polymeric wrapping film, each said film roll comprising a core and a plurality of convolutions of said film wound on its said core, each said core being generally cylindrical and having a bore, and each said core being of greater axial length than the axial length of the wound film so that there is an end of the core projecting from each side of the wound roll of film, said package comprising a box having sides and ends and that is long enough to accommodate at least two of said rolls of film in a side-by-side arrangement with their cores aligned on a generally common axis. at least two of said film rolls being disposed in said box with their cores aligned on a generally common axis, first partition means disposed in said box intermediate said adjacent pair of film rolls and interposed between the cores of said rolls and disposed in parallelism with said box ends, and other, second partition means disposed in said box adjacent and engaging against the ends of said box respectively, each said partition means being formed with a central opening that is in registry with the bores of said cores of said film rolls, each said partition means engaging against and being supported from the inner surfaces of the sides of said box, mandrel means inserted in the bores of said cores and through the central openings in said first partition means, said mandrel means having a lesser axial length than the axial length of the aligned cores of said rolls and said first partition means, but projecting through the central opening of said first partition means and being supported thereon, a pair of caps each having a central boss and a peripheral flange, the bosses of said caps being inserted respectively through said central openings of said second partition means at the opposite ends of said box respectively, and extending into the ends of the cores of said film rolls adjacent the respective opposite box ends in a snug fit, said mandrel means thereby being confined within the aligned bores of said cores spaced axially from said bosses and said second partition means, and said mandrel means engaging against and resting on said first partition means and thereby, with said end caps, supporting said rolls in the box on said partition means, said rolls being positioned so that the wound film is spaced from and is not in contact with the walls or ends of the box, and is spaced from and not in contact with the wound film on any adjacent roll, the inner, confronting film edges of the wound film on adjacent film rolls being spaced apart from each other and also from the partition that is disposed intermediate the rolls, by reason of the ends of the cores projecting from the film rolls.
