Polypropylene Big Bags are used for the transport and storage of large quantities of solid material. They are particularly resistant and can cope with very high loads. The laminated fabric prevents the formation of humidity, the penetration of dust from outside and makes the bag structure more stable. The skirt opening allows the articles inside the bag to be carefully sealed, while on the bottom there is a discharge valve that facilitates the emptying of the products. They are available in different sizes as required.
