Flour, cereals, rice, sugar, and many dry bulk ingredients are increasingly handled in big bags. This choice optimizes flows from milling to final packaging, reducing intermediate steps and improving process cleanliness. But the “food + powdered product” combination requires some extra attention.

Operationally, the density of the product must be considered: very light flours volumetrically fill the big bag before reaching the weight limit, while high-density grains can quickly bring it to capacity limit. Properly defining the size and capacity of the big bag avoids both underutilization and overloading.

Dust and electrostatic charges are generated during filling and emptying : in some cases, especially in potentially explosive atmospheres, antistatic or conductive big bags (type B, C, D) and appropriate ATEX procedures should also be evaluated. The design of loading and unloading ports (valve, skirt, dust suppression systems) contributes greatly to the containment of dust emissions in the department.

Finally, logistics: big bags must integrate with silos, packaging lines, and automated warehouses. This means defining dimensions compatible with lifting systems, belts and storage spaces, but also providing identification systems (barcodes, QR codes, labels) that facilitate FIFO management and traceability by lots.

Sebino Pack can support mills, rice mills, confectionery companies, and ingredient manufacturers inanalyzing flows, proposing food grade and, when necessary, anti-static big bag solutions with configurations suited to the different steps (from harvesting to processing to final packaging).
