POLY-VALVE SACKS

Polythene valve sacks have an opening or valve in one corner through which the sack is filled. The valve is made with an inner flap which functions as a self closing check valve after filling. Sacks can be produced with either internal or external valves together with embossed strips and/or GUR finish preventing movement on the pallet.

They can be filled either automatically or manually with the main benefit of producing a square box type sack which sits very stable allowing you to stack many bags on to a single pallet.
