Woven Polypropylene Coated
Woven polypropylene coated bags are a lightweight, breathable packaging solution which enables the flow of air circulation, while simultaneously being rip-resistant and durable. These properties make our woven polypropylene bags an incredibly versatile packaging solution. These light-weight, tear-resistance and durability properties make it a perfect option to store sugar, animal feed, grains, etc.
The process:
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.
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.
