Abstract
A packaging system is provided for a plurality of packages which are vulnerable to damage when cut into by a sharp instrument. The packaging system includes a rectangular container enclosing all of the packages and being formed of a rectangular lid and a rectangular tray configuration, preferably in a mating and nonoverlapping configuration, to form the container. A shrink wrap material is applied about the container and shrunk into engagement therewith so as to encircle the container in three dimensions and thus hold the lid and tray in the mating configuration. The shrink wrap material is suitably weakened to allow a manual tearing of the shrink wrap material to release the lid and hence open the container. The shrink wrap material is weakened by a longitudinal slot located adjacent the lid and extending from one side of the lid to an opposite side and two paired series of weakenings in the shrink wrap material. Each respective paired series extends laterally away from the slot and each paired series has one series of weakenings separated from the other series and provided along the lid adjacent a respective side. Preferably, the packages are rectangular and arranged in two rows …
