The main factors affecting the service life of container liners are as follows:
- Environmental Factors: These include climate, temperature, and humidity. Especially under harsh weather conditions, such as high temperatures, low temperatures, rain, and snow, the aging of container liners is more pronounced.
- Physical Factors: During stacking, unloading, and loading, container liners are susceptible to physical damage, such as friction, impact, and compression. These factors also contribute to their aging.
- Chemical Factors: When storing goods, container liners may be exposed to chemicals and bacteria from the cargo, triggering chemical reactions and further leading to aging.
- Material Factors: The materials used to manufacture container liners also affect their service life. For example, whether virgin granules are used, whether excessive recycled materials are added, and whether modifiers (such as calcium carbonate masterbatch) are added will all affect the aging resistance of the liner.
- Production Process: The price of color masterbatches varies significantly. Some pigments can prevent the aging of the FIBC (Flexible Intermediate Bulk Container) and greatly affect its lifespan. For example, whether rutile titanium dioxide masterbatches with surface coating are used, whether a yellow pigment with excellent weather resistance is used, and whether the blue pigment used contains free copper all affect the lifespan of the FIBC.
In conclusion, to ensure the lifespan of container liners and guarantee the safe transportation of goods, the above factors must be fully considered when selecting and using container liners, and corresponding measures should be taken to extend their service life.
