Polyester is the most rigid of all strapping materials. It elongates significantly less than polypropylene and retains tension over a longer period. Polyester is nick resistant and can be sealed with seals, heat or friction welds. Because polyester offers the greatest strength and highest retained tension of all plastic strapping, it is frequently used on heavy duty loads that need high initial tension along with high retained tension during handling and storage. Common applications are empty cans and bottles, lumber and heavy, rigid palletizing. Polyester has a smooth, shiny finish and is easy to dispose of and recycle.Polypropylene strapping is the most commonly used and least expensive of all strapping materials. It is light and easy to apply and recycle. Characteristics include high elongation and elongation recovery, but low retained tension. Polypropylene is an excellent choice for light duty palletizing, unitizing, carton closing and bundling. Because of its embossing (or waffle) pattern, strap thickness is not a useful measurement. A standard 1/2" machine grade strap can be embossed to a thickness of anywhere between .014 and .030, depending upon how deep the embossing pattern is. An overly embossed strap will be thicker, but will have a lower break strength. Carton Reinforcement: A 3:1 ratio of strap to carton weight is recommended. For a 100 lb package this could be done with (1) 300lb tensile strap or (2) 150lb straps. Unitizing and Bundling: A 5:1 ration of strap to carton weight is recommended. Palletized Cases: Required Tensile Strength = (Pallet Weight x 1.5) / # of Straps Ordering from Packaging Supplies Company is pretty simple.

Your heavy duty jobs are best handled by fiberglass reinforced tape, while lighter cartons are easily handled by the less expensive non-reinforced tape. Water activated tape is unaffected by heat, cold, light or humidity and works well in dusty and dirty environments. Water activated tape is recyclable and provides a strong, secure seal that cannot be broken without detection Steel is the strongest of all strapping materials. It is recommended where high strength is necessary, low elongation is important and where the product is extremely selfsealbag sharp or hot. Steel is sealed using mechanical seals selfsealbag and notch (sealless) joints. It is most commonly used in steel service centers, rail car applications and heavy construction applications.
