Typical Lifespan Range
♦ Polypropylene (PP) ton bags
1-3 years: This lifespan is achieved under normal use (no overloading, no damage from sharp objects), and stored away from sunlight.
Six months to one year: Prolonged exposure to UV rays or humidity significantly shortens the lifespan.
♦ High-performance materials (such as PET) ton bags
The lifespan may be extended to 3-5 years, especially after anti-aging treatment (such as UV coating).
Key Factors Affecting Lifespan
♦ Ultraviolet rays
Direct sunlight can cause a ton bag's strength to decrease by 25% within one week and by 40% after two weeks.
♦ Usage conditions
Overloading, frequent friction, or collisions accelerate aging.
♦ Storage environment
A cool, dry environment extends the lifespan; humid or high-temperature environments shorten it.
Suggestions for Extending Lifespan
♦ Choose thicker, wear-resistant materials
For example, high-density PP or composite materials to increase tensile strength.
Avoid exposure to harsh environments.
Store away from sunlight, rain, and heat.
Inspect and repair regularly.
Repair any damage promptly with specialized tape or glue.

Food/Pharmaceutical Industry: Regular replacement is required (usually every 1-2 years) to ensure hygiene and safety.
Building Materials/Mining Industry: High-strength ton bags can last up to 3-5 years under normal use.
