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 sealing welds. Because polyester offers the greatest strength and highest retained tension of all plastic strapping, it is frequently bag 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 sealing 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 bag is an excellent choice sealing for light duty palletizing, unitizing, carton closing and bundling. Because of its embossing (or waffle) pattern, strap thickness is not a useful measurement. bag A standard 1/2" machine grade sealing 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 bag 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. sealing Palletized Cases: Required Tensile Strength = (Pallet bag Weight x 1.5) / # of Straps

Packaging Supplies Company''s boxes are "200 lb burst test" certified. (We sealing do carry bag and sealing some "275lb burst test" certified boxes too.) This means that the corrugated walls of bag the box would require 200 pounds per square inch of force to break through the wall of the box. The burst test has been a standard certification for years. More recently a new certification test has started to be used called the Edge sealing Crush Test (ECT). Generally, 200lb test boxes are 32 ECT. ECT is the edgewise-compressive strength, parallel to the flutes of a short column of corrugated fibreboard. Test results are reported as the pounds per inch required causing compression failure. ECT relates directly to box compression strength which is important in today''s world of box stacking. For certain items, mailing supplies provide a complete protective package that is ready to ship.
