Claims
- 1. A single use processing substrate, comprising;
a first cut-resistant layer having a first surface area and including an absorbent ply and a thermoplastic material ply, wherein the first layer includes a plurality of non-circular apertures therein; and a second layer having a second surface area and including an absorbent ply and a thermoplastic material ply, wherein the first layer is secured to the second layer such that a portion of the second surface area is laterally disposed outside of the first surface area.
- 2. The single use processing substrate of claim 1, wherein the first layer absorbent ply is disposed below the first layer thermoplastic material ply.
- 3. The single use processing substrate of claim 1, wherein the second layer absorbent ply is disposed above the second layer thermoplastic material ply.
- 4. The single use processing substrate of claim 1, wherein the apertures are rectangular-shaped.
- 5. The single use processing substrate of claim 1, wherein the apertures are square-shaped.
- 6. The single use processing substrate of claim 1, wherein the apertures are elliptical-shaped.
- 7. The single use processing substrate of claim 1, wherein the apertures are in the form of slots.
- 8. The single use processing substrate of claim 1, wherein the apertures are regularly spaced.
- 9. The single use processing substrate of claim 1, wherein the apertures are irregularly spaced.
- 10. The single use processing substrate of claim 1, wherein the first layer is secured to the second layer by adhesive.
- 11. A single use processing substrate, comprising;
a first cut-resistant layer having a first surface area and including an absorbent ply disposed below a ply of thermoplastic material, wherein the first layer includes a plurality of non-circular apertures therein; and an unfolded second layer having a second surface area and including an absorbent ply disposed above a ply of thermoplastic material, wherein the first layer is secured to and substantially centered on the second layer in at least one dimension such that a portion of the second surface area is laterally disposed outside of the first surface area.
- 12. The single use processing substrate of claim 11, wherein the apertures are rectangular-shaped.
- 13. The single use processing substrate of claim 11, wherein the apertures are square-shaped.
- 14. The single use processing substrate of claim 11, wherein the apertures are elliptical-shaped.
- 15. The single use processing substrate of claim 11, wherein the apertures are in the form of slots.
- 16. The single use processing substrate of claim 11, wherein the apertures are regularly spaced.
- 17. The single use processing substrate of claim 11, wherein the apertures are irregularly spaced.
- 18. The single use processing substrate of claim 11, wherein the first layer is secured to the second layer by adhesive.
- 19. A processing substrate, comprising:
a first material having a liquid-permeable, cut-resistant surface; a second material disposed adjacent the first material and having a liquid-absorbent portion; and a third material disposed adjacent the second material and having a liquid-impermeable portion; wherein the first, second, and third materials are formed into a roll.
- 20. The single-use processing substrate of claim 19, wherein glue bands are disposed at intervals along a length of the roll and extend perpendicular to the length of the roll wherein a portion of the processing substrate can be severed from the roll at one of the glue bands.
- 21. The single-use processing substrate of claim 19, wherein perforations are disposed at intervals along a length of the roll and extend perpendicular to the length of the roll for detaching a desired length of the processing substrate.
- 22. The single-use processing substrate of claim 19, wherein the first and third materials are sealed together along a length of the roll.
- 23. The single-use processing substrate of claim 19, wherein the first material includes apertures therein.
- 24. The single-use processing substrate of claim 23, wherein the apertures are circular in shape.
