Causes of white spots on PET strap
PET strap is a kind of packing material with good tensile strength and excellent welding performance. It is favored by various industries because of its good tension retention ability, long-term no slack, and excellent resistance to shocks during long-distance transportation. PET straps are mostly green or black. White spots are not of good quality, so why do PET straps have white spots?
There are two reasons for the white spots in the PET straps: one is that the internal additives are resolved when water is absorbed; the other is formed by hard solidification in water. To avoid white spots, it is necessary to strictly control the proportion of water absorption in the process of natural water absorption by the strapping, especially to adjust it according to factors such as the temperature and humidity of the surrounding environment.
Also pay attention to when buying, once you find white spots or cracks, do not buy, to avoid unnecessary losses. In the production of PET straps, it is also necessary to avoid operating errors that affect the quality and effect of the products, and to do relevant inspections in time.
