As mentioned earlier, pet strapping is the best alternative to steel strapping. The strap is made by a process in which an extruded strands or sheet of polyester is subjected to a plurality of stretching steps with a final stretch ratio of at least 5 to 1. Raising the temperature of the strap in at least one of the stretching steps is preferred. The SUPERBAND strapping machine from Messersi is of high quality guaranteed with constant tension at all the stages of packaging providing full safety in transit. Messersi produces this machine in a wide range of sizes, for every application. However, its pet strapping systems are most suitable for bricks and tiles industry and are reliable.
