A multi-unit package comprising a cellulosic tray with a group of articles in the tray and a flexible film sheet extending over the group of articles and overlapping the tray side walls where the film sheet has been first bonded to the outside of the tray side walls while leaving an unattached skirt portion between the first bond and the edge of the film sheet and where the unattached skirt portion has been heat bonded to the outside of the tray side walls subsequent to the first bond to cause the skirt portion to lie in juxtaposition with the outside of the tray side walls to enhance the effective transparency of the skirt portion. The method and apparatus for forming the package is also contemplated by the disclosure.

A multi-unit package comprising: a cellulosic tray including a bottom wall and a pair of spaced apart upstanding side walls along opposite sides of the bottom wall; a group of articles on said bottom wall between said side walls; and a flexible film sheet extending over said group of articles and overlapping said tray side walls, said film sheet overlying said side walls of said tray to form a skirt and bonded with heat and pressure to each of said tray side walls by its own substance with a primary bond extending along the length of said side wall, the primary bond having a height less than the height of said walls and located adjacent that edge of said side wall opposite said bottom wall and with a skirt bond bonding that skirt portion of said film sheet between said primary bond and the edge of said film sheet along the length of said side wall, the skirt bond having been made subsequent to the primary bond by sequentially heating and pressing said skirt portion against said tray side wall so that the section of said skirt portion raised to bonding temperature at any one time has a length less than the length of said tray side walls.
