Plastic sheeting (also known as plastic tarpaulin, tarp or polythene sheet) is a sheet of strong, fl exible, water resistant or waterproof material. Although different qualities exist, those suitable for humanitarian relief are made from polyethylene. A standard sheet has a black woven or braided core and is laminated on both sides. All plastic sheeting must reach minimum performance standards .
Polypropylene is a crystalline plastic that is known for high strength-to-weight ratio, excellent chemical resistance and high performance in thermoforming and corrosive environments. Polypropylene sheet is often used for orthotic and prosthetic devices, plating and anodizing process equipment, plenums, manifolds, and pump components.
Features of Polypropylene Sheet:
- Appropriate for applications to 180°F(82°C).
- Low moisture absorption.
- Resists most acids, alkalis and solvents.
- Corrosion resistant.
- Thermoforming performance.
- Meets USDA federally inspected meat and poultry packing guidelines.
