Polyester (PET) strapping can save about 50% cost compared with steel strap. Through comparative analysis between PET strap and steel strap, we found that 25mmx1.2 mm PET strap can replace 32mm*1mm steel strap in a heavy packing case. With the same breaking strength, PET STRAP can get 6 times longer than steel strap in the same size, as PET strap is only 1/6 of steel strap in density. Thatâs why our PET strap can dramatically help customers save 50% cost.
