Proper Storage and Handling of Jumbo Bags and Woven PP Sacks

Polypropylene is naturally resistant to moisture and most common chemicals, but it has one well-known weak point: prolonged exposure to direct sunlight. UV radiation gradually breaks down the molecular structure of polypropylene fibers, making the fabric brittle and weak — even when it still looks fine on the outside.

For this reason, the best way to store empty jumbo bags and sacks is in a covered space, away from direct sunlight. If covered storage isn't available and bags must sit outdoors for extended periods, ordering a version with UV-stabilizing additive from the start of production makes a real difference in the product's lifespan.

Warehouse floor moisture is another factor — folded bags shouldn't be stacked directly on bare or damp ground; using pallets or a synthetic floor covering stops moisture from being absorbed from below. During handling, dragging bags across rough surfaces or metal edges should also be avoided, since even a deep scratch can become the starting point of a tear on the next load.

For customers who store bags outdoors for long periods — such as construction sites or seasonal agricultural warehouses — Arian Baft Partow offers production with UV-stabilizing additive; simply state this requirement when placing the order.
