Valve & open mouth

Valve models use a PP valve or pocket valve at the opening to make filling easier. On request, a UV stabiliser makes the sacks resistant to sunlight.

Open mouth models have no valve and are cold cut. The block base lets the bag stand upright and stack easily. They are used for pulses, flour, feed, fertiliser, chemicals and construction chemicals.
