Woven Polypropylene Bags for Dry Goods 

Woven Polypropylene bags are widely used for material packing for fertilizer, cement, sand, food grains, sugar, cattle feed, and many other industries. Woven PP bags have the advantages of lighter weight, higher strength, better corrosion resistance, and tear resistance. These bags allow sufficient passage of air to the packed items and ensure the phenomenon of ‘breathing’ space in packed grains. These moisture proof woven sacks are perfect for packing of rice, spices, flour, fertilizers, sugar, agro products, and other materials.

The U-shaped panel bag consists of three main panels - one extending over the bottom and two sides and two additional pieces of fabric sewn into the two sides of the U piece that form the other two sides. Similar to other structural types, U-shaped panel bags will remain square when filled. U-panel bags are the industry standard and are the most popular type of construction, offering high safety workload (SWL) and ruggedness.
