The valve bag is completely closed and pasted at both ends, with a filling spout or “valve” on one end. Valve bags were created for high speed production lines that required agile palletization. The heat seal valve, which guarantees cleanliness and minimal product dispersal, makes this a very widely adopted solution even in the most traditional sectors. Valvosacco manufactures valve bags with capacities from 5 to 50 kg, depending on the model.
Reasons for choosing the valve bag
Perfectly sealed, sturdy and secure, the valve bag is traditionally used in sectors in which it is especially important to minimize wastage of the bagged material, e.g. flour in the food industry, and powders in the building construction and chemical sectors. Apart from traditional applications, the exceptional versatility of the valve bag means it is widely used in many other sectors.
