For those in the construction, mining, or agricultural sectors, the Big Bag is not just a container, but a storage garrison that often has to withstand months of sun, rain, and temperature fluctuations.
Polypropylene (PP), by its nature, is sensitive to ultraviolet rays: prolonged exposure without proper protection can lead to crystallization of the fibers, making the bag fragile and dangerous during handling.
UV degradation is a photo-chemical process. The sun’s rays break polymer chains in the fabric, causing loss of tensile strength, pulverization , and safety hazards.
At SebinoPack, we use state-of-the-artHALS (Hindered Amine Light Stabilizers) additives that not only screen out rays, but also block chemical degradation reactions as soon as they are triggered, prolonging the life of the bag by up to 50 percent more than cheap products.
In addition to material choice, proper bag management can really make a difference:
- Covering Big Bags with opaque tarps further reduces wear and tear
- Before lifting a bag that has been stored outdoors for months, always check that the color of the fabric is intact and has no “dry” or brittle areas
- Use FIFO (First-In-First-Out) logic to minimize the total exposure time.
Investing in a Big Bag with advanced UV stabilization means protecting not only the goods contained, but also the safety of your workforce. With SebinoPack technologies, outdoor storage stops being an unknown and becomes a controlled and safe process.
