Abstract
A method of manufacturing a single use processing substrate includes the step of extruding a first layer having ridges and troughs between the ridges. The method further includes the steps of placing a second layer into the troughs while the first layer is pliant and compressing the pliant ridges so that the second layer is bound into the troughs.
Claims6
A disposable cutting sheet for cutting and preparation of food items thereon, comprising:
- a first cut-resistant layer having a plurality of projections extending away from troughs disposed between the projections, wherein the first layer comprises a thermoplastic resin;
- and
- a second layer of absorbent material disposed in the troughs and captured therein by overhanging portions of the projections.
A disposable cutting sheet for cutting and preparation of food items thereon, comprising:
- a first layer having a plurality of projections with troughs therebetween, wherein the first layer comprises a thermoplastic resin;
- a plurality of absorbent portions disposed within each of the troughs, wherein the absorbent portions are captured within the troughs by overhanging portions that extend from the projections of the first layer and wherein the overhanging portions are discontinuous to allow fluids to migrate from the first material into the second material.
