    摘要： 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.

    摘要： A high performance absorbent particulate composition and a method of preparation in which non-colloidal solid filler core is substantially encapsulated within a bounding layer of hydrogel forming polymer is disclosed. In preferred embodiments, the size of the solid filler core is about 10 to about 1500 microns contributing about 20% to about 90% by weight of the composition. The particles of the present invention provide rapid absorption of a large volume of aqueous fluids. A wide range of performance properties are achieved through selection of the filler core and the polymer.
