Manufacturing woven polypropylene bags

The manufacturing process consists of three basic steps.

Extrusion: Virgin polypropylene granules, calcium carbonate, ultra violet stabilizer and colour pigment being melted and converted into tapes in an extrusion plant. This is the first stage and determines the tensile strength of the tapes.

Weaving: The extruded tape bobbins are loaded on to a creel (warp tapes) and threaded through the headle wires of the circular loom. Weaving looms consists of 4,6 and 8 shuttles which are loaded with bobbins (weft tapes). Here the tapes will be woven into fabric of a required GSM and size, and will be wound in roll form. polypropylene-bags-manufacturer-supplier-industrial26

Converting: This consists of a cut, print and sew operation, which converts circular woven rolls into individual bags. Reel-to-reel printing is done on the fabric and converted into bags with automatic cut and single hem sewing lines. The wider bulk bag fabric is printed on an individual single pass flexographic printer and converted by manual sewing machines.

Strength and other advantages

Woven polypropylene bags offer many advantages over paper and jute:

  • Lighter weight
  • Much greater bursting strength
  • Better pest resistance
  • Resistant to tearing and cracking
  • Reusable
  • Can be air permeable and moisture, pollutants, bacteria, mildew and oil resistant
  • Does not degrade when wet
  • Very affordable and easy to produce
  • Non-toxic
  • Non-staining
  • Light in weight with lower density
  • Products can breathe until air dry or kept waterproof with a laminated film
  • High operational temperatures with a melting point of 167°c
  • Resistant to most alkalis and acid, organic solvents and degreasing agents
  • Approved for food use
  • Good preservation of taste


Polypropylene is fully recyclable and can be melted down to form other products.   Due to its strength it can also be re-used multiple times.
