A valve on the bag is a quick and simple way to close the bag after filling as it eliminates the need for sewing.  Valve bags can be manufactured with internal or external valves and tamper evident heat seal valve bags are also available.  We can also supply valve sacks with a 'tuck in' valve for use with fine powders.

High porosity paper allows fine powders to fill quickly and can work without perforations which helps to keep the workplace clean. Wet strength paper and polylining mean there is a valvebag suitable for virtually all applications.

Valve sacks are also available manufactured from polyethylene or woven polypropylene.  Different grades and thicknesses of material are available and the valve type and size can be tailored to your requirements.
