Polyester textile strapping as hot melt version consists of polyester yarns that are hot melt. Depending on the strap width and thus on the number of yarns per strap, breaking strength can be 390 kg for a 13 mm strap and up to 1,400 kg for a 35 mm strap. Due to the hot melt, this type of strap feels like waxed and results in an optimized system strength when used with galvanized metal buckles . Polyester hot melt strapping is suitable for various applications - especially when high breaking strength are required but PET strapping cannot be used - either due to high investment costs for battery-powered strapping tools or due to too small surfaces (= round packaging goods). Only when packaging goods have sharp edges, woven or composite polyester strapping should be used.
