"Sintron strap" polyester (polyethylene trerephthalate) strapping is a new alternative of steel strap. It is being increasingly used for strapping medium and heavy loads in place of steel (iron) strapping. It can also be used in place of other plastic straps where high tensile strength is required. "sintron strap" has been installed a plant to produce polyester strapping (pet) ranging in standard width from 12 mm. to 19 mm. and thickness from 0. 50 mm. to 1. 27mm. With quality assurance by controlling it's quality with the parameters of strapping like tensile strength, break strength, elongation percentage in a latest computerized quality control equipments.
