Polythene Valve Sacks are perfect for a wide range of products such as plastic granules / powders, pigments, compounds and food stuffs.
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.
Polythene Valve Sacks 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.
Polythene Valve Sacks can be printed up to any combination of 6 colours on 2 sides e.g. 4 x 1 side + 2 x reverse side etc.
