Description

Valve sack with interior top

A sack which mixes the properties of the valve sack with lateral folds and double (top and bottom) valve sack. By combining both formats we have achieved a sack with similar performance and security to the second one, but with a lower price as the bottom of the sack only has a flat seal; the width of the folds allows the required valve width and good pallet stacking at an economical price.

Valve sack with a reversible top

With the same properties of the valve sack with interior top, to which a protruding valve is added. When full, the protruding valve is folded into a space provided for it avoiding any possibility of product spills. The valve can be heat-sealed before folding into the cavity which provides a totally hermetic seal.
