Abstract
A thin polypropylene sheet is extruded flat, with a thickness in the range of 0.008 to 0.060 inches with a Rockwell hardness between 72 and 90 and a flexural modulus between 55,000 psi and 200,000 psi. The resultant surface may be utilized for cutting and chopping foods. A sharp knife will penetrate, but not perforate, the sheet material to not dull the knife while maintaining the integrity of the surface. When flexed around its longitudinal centerline, the sheet material develops substantial cantilever beam strength, so as to transport food articles after preparation into an appropriate container.
Claims9
A flexible sheet for cutting and handling articles thereon, comprising:
- a sheet of flexible resilient plastic material having lay-flat characteristics, a width greater than 6 inches and a length greater than 10 inches;
- said plastic material having a Rockwell hardness between 72 and 90;
- said plastic material having a thickness between 0.008 inches and 0.060 inches;
- said sheet having sufficient cantilever beam strength when flexed around the longitudinal centerline and held proximate a first end to support an article spaced at least 10 inches from said first end and weighing at least 5 ounces.
A flexible cutting sheet for food preparation, comprising:
- a sheet of plastic sheet material having a thickness of less than 0.030 inches and a flexural modulus in the range of 75,000 to 200,000 psi;
- said sheet having a Rockwell hardness in excess of 72.
