Issues and Solutions with Container Bags: Problems with Strap Breakage Accidents (3)

PP resin is prone to UV degradation from sunlight! Here are some measures to prevent UV degradation due to long-term storage!

The suspension belt that supports the load, which can be considered the lifeline of a container bag, excels in tensile strength but also has its weaknesses. Let's discuss the causes of accidents where the belt breaks. The material of the belt is primarily made of PP resin. PP resin is prone to degradation from ultraviolet rays in sunlight, and when exposed to UV light, the electronic chains can break, leading to a decrease in strength and, in severe cases, powdering. If weathering agents are not properly added, even indoor storage can cause significant damage over time from light entering through warehouse windows. However, it is possible to take measures depending on the amount of UV weathering agents added and the color of the material. Our company manufactures products with a 3-year or 5-year warranty for weather resistance by incorporating specific weathering agents and using black pigments that are less permeable to light. [Measures] ■ Add specific weathering agents ■ Use black pigments that are less permeable to light → Our company also manufactures products intended for outdoor use, such as sandbags, with 3-year or 5-year warranties. *For more details, please refer to the PDF document or feel free to contact us.
