A high quality composite corded strapping product, which is also known as synthetic steel, by using polyester fibers coated with clear polypropylene. Among various strapping solutions in the industrial packaging world, composite corded strapping is the most recent technology for cargo securing.
Steel is the oldest and highest tensile strength strapping. It is available in a variety of widths and thicknesses as well as variations in tensile strength. Steel is used for heavy-duty holding where high strength and minimal stretch are desired. Surface finishes for steel strap include paint and wax, bluing or zinc and wax.
Oriented or tensilized polyester and nylon are the strongest plastic strapping products and are used as a viable alternative to steel strapping in the some industries. It is available in a variety of widths and thicknesses as well as variations in strength. Polyester provides excellent retained tension on rigid loads.
Polypropylene strap (oriented or tensilized) is an economical material designed for light to medium duty unitizing, palletizing and bundling. It is available in various widths, thicknesses, and polymer variations (e.g., copolymers). Most polypropylene is embossed some of which is printed. This product offers higher elongation at break but tends to have irrecoverable dead stretch with constant stress.
