As the most common strapping belt for industrial packaging, PET plastic steel belt has a wide range of uses. Compared with traditional PP belts and steel belts, its tensile strength and flexibility are the best. However, in daily packaging and transportation, it is inevitable that PET plastic steel belts will become brittle and crack. As a result, transportation time is delayed. So what causes PET plastic steel belts to crack and how to avoid them?

Plastic steel belt

      1. Plastic steel belts mainly use polypropylene as the main raw material. The higher the purity of the raw material, the stronger its tensile strength and flexibility. In the production process, some manufacturers use impure materials or add an incorrect proportion of pure materials in order to control costs. If it is not used properly, it will cause the plastic steel belt to crack.
       2. Many plastic steel belts on the market are made from recycled bottle flakes. A certain amount of softener needs to be added during the production process. At the same time, the drying temperature and time of the raw materials need to be strictly controlled. If the temperature and time are not controlled well or the proportion of the flexible agent is wrong, such plastic steel belts are prone to becoming brittle and cracking.
       3. If there is no problem with the product quality of the plastic steel belt itself, then the problem of baler failure must be considered. If the baler is not cleaned in time, there will be a lot of debris on the friction plate on the fuselage, which will reduce the friction when baling. When bonding at the interface, it will easily lead to instability and cracking.
       4. Some poor-quality plastic steel strips on the market will corrode and crack in low weather or long-term humid environments. Therefore, purchased packing tapes should be properly stored in a timely manner. Generally, plastic steel belts produced by regular manufacturers will undergo strict quality inspection before leaving the factory. Qualified products will basically not crack as long as they are handled properly.
       Therefore, if we want to avoid the cracking of plastic steel belts, we should avoid it from the source. When purchasing plastic steel belts, do not blindly pursue cheap prices and learn more about the brand and qualifications of the manufacturer.
