People who bale and transport recycled materials and other commodities will be interested in a product from Caristrap International Inc, a company founded by innovator-entrepreneur Dr. T.J. Karass in 1954. The company specializes in strapping systems for the transportation of goods, as well as for specialized applications.

Caristrap has focused its expertise on two product groups: Weatherguard and Caritape. Weatherguard is a high-strength non-metallic strapping system for the transportation and storage of goods. This “synthetic steel flat rope” is available in various sizes and strengths for a range of conditions. Caritape is developed for applications using non-woven materials. These are made with a variety of materials including oriented fibres of heat resistant, insulating fiberglass, recyclable paper, heat shrinkable polyester, cotton, or other special materials such as Kevlar and carbon fibres.

Both product lines replace all sizes of steel strapping with a 20 to 25 per cent savings. In terms of occupational safety, rigid strapping is often a source of personnel accidents and may cause damage to packages. The manufacturer says Caristrap and Weatherguard are soft, flexible, and do not cut people or packages.

A key benefit is that Caristrap is considered 2.5 times “tonger” (energy-to-break) than steel strapping. Tensile strength is not the only stress a strap has to endure. In transit, shock is a common source of strap failure. Caristrap has high shock-absorbency and will not break or snap. Stress applied to steel results in permanent elongation or snapping. Weatherguard has memory, so loose straps are not a problem.

On the environmental front, the strapping is easily compacted and can be disposed using regular garbage pickup or reused. The material may be of interest to beverage can recyclers since acids are used to remove the paint on beverage items; this same acid completely dissolves and destroys Caristrap, which is also bio-degradable.
