This invention relates to a case can package wherein two twelve can-one-half case can packages are joined to form a one case can package by means of an overwrap. The package film of the one-half case can packages is provided on the outer surface thereof with a suitable overprint in the form of a resist which prevents bonding of the overwrap film thereto. The overwrap film interlocks with the cans of the two one-half case can packages to form a readily handleable one case package unit. The overwrap film is readily removable to present two one-half case can packages for individual sale. The overwrap joining the two one-half case can packages eliminates the need for the usual paper board tray, which is quite expensive, and at the same time provides for improved stacking of the can packages in case lots on pallets.
A method of packaging cans of products in case lots, said method comprising the steps of arranging cans forming a one-half case in rows and columns, wrapping said one-half case of cans in a package forming film and heat shrinking the film about the cans to form a one-half case package, repeating the above steps to form a like one-half case package, arranging the two one-half case packages in aligned adjacent relation, providing an overwrap film, applying a resist selectively to said package forming films, wrapping the two one-half case packages in an overwrap film, and heat shrinking the overwrap film about the two one-half case packages without substantial bonding of the overwrap film to the package film due to the presence of the resist to form a case package, the overwrap film being of a width less than the package film, and opposite longitudinal edge portions of the package film being free of the resist for a distance slightly less than one-half the differences in width, wherein transverse shifting of the overwrap film relative to the package film may be prevented by bonding of an edge portion of the package film.
A case can package comprising two one-half case can packages disposed in side by side relation, said one-half case can packages being identical and each one-half case can package including cans arranged in rows and columns and a package film surrounding said cans and shrunk tightly around said cans in interlocking relation therewith to form a readily handleable unit, and an overwrap film surrounding two one-half case can packages and shrunk tightly around said one-half can packages in interlocking relation therewith to form a readily handleable case can package, and a selected one of said package film and said overwrap film having a surface with a resist coating thereon opposing the other of said films and substantially preventing bonding of said overwrap film to said package films whereby said overwrap film is readily removable from said one-half case can packages without damaging said package films, the package film of each of said one-half case can packages defining at opposite ends thereof an open area, and said overwrap film defining at opposite ends of said case can package a similar opening generally aligned with said package film openings and of a greater height and width.
