Polypropylene sacks are excellent as durable packaging for many loose materials in various branches of industry. The structure of the polypropylene weave ensures sack permeability, which is important for products that 'breathe'. They are perfect for transporting and storing heavy products like coal, grit, pea coal, rubble and briquettes. We carry sacks holding 25 kg. Additionally we can print a custom design on the sacks.
