Abstract
In a package for food products having a tendency to exude liquids, an absorbent pad underlying the food product in a tray is made up of an absorbent layer underneath a layer of polyethylene film having an array of elongated, thermoformed apertures. These apertures efficiently transport liquid into the absorbent layer and resist reverse flow when pressure is applied to the absorbent pad, thereby making it possible to utilize a paperboard tray. The absorbent layer and apertured polyethylene film can be laminated together with a paperboard base layer, and the laminate can then be die cut and folded to form a tray made up entirely of the laminate and having its bottom and side walls lined with the absorbent material and apertured film.
