Jumbo Bag & FIBC Shredder Machine for PP Raffia Recycling

Yes — the bag body is woven polypropylene raffia, a clean thermoplastic that recyclers actively buy. Shredded, washed and agglomerated, it pelletizes into reprocessed PP for molded products and non-food woven applications. What blocks recycling is never the polymer; it is the form (a bag too tough and bulky to handle), the attachments (PE liners, webbing loops) and the residue from the previous cargo. Solve those three with sorting and shredding, and used FIBCs convert from a disposal liability into a saleable raw material.

It depends on your buyer, not the machine. The dual shaft shredder will tear liner, loops and bag body together — but the output is then a PP/PE mix, which raffia buyers discount or refuse. If you sell to a quality-conscious PP recycler, pull loose liners out and cut away loops before feeding; if the output goes to a mixed-plastic stream, shred everything together. We recommend settling this at the trial stage with a sample of your actual bags, so the operating procedure matches the price your buyer pays.

Empty them properly before shredding: invert, shake or beat the bags and collect the fines separately. Powder residue accelerates blade wear (cement dust is abrasive) and contaminates the shredded raffia, which costs you at the weighbridge. For chemical residues, follow your plant’s decontamination norms before the bags enter the waste stream — a shredder reduces size; it does not neutralise chemistry. Washed-and-dried bags shred cleanest and fetch the best raffia prices; for visibly contaminated lots, plan a downstream washing stage after shredding.

Woven raffia is engineered to resist tearing — that is its job when 1,500 kg of cargo hangs in it. In a high-speed blade grinder the fabric flexes away from the blades, rides the rotor and wraps around it until the machine stalls. A dual shaft shredder defeats this by gripping: interlocked blades on counter-rotating shafts pull the fabric positively into the shear zone at low speed and high torque. The same grip-and-tear principle is why our dual shaft shredders handle cement bags, carry bags and non-woven fabric that defeat ordinary grinders.

Think in kilograms, not bag counts — FIBC weights vary widely with size, GSM and whether loops and liners are included. A dual shaft shredder processes plastic waste at a rate set by the model, your feed rate and material density; a dedicated bag shredder is sized against your stated monthly bag volume. Weigh a representative sample of your empty bags, multiply by your monthly generation, and send us the figure — we will recommend a machine with sensible headroom rather than one running flat-out from day one.

Every machine is quoted to the job. What moves the number is capacity, throat size, motor rating, MS or SS construction and the automation you add — a blower, a conveyor, a control panel. Our guide to what drives machine cost walks through each of those; send us your material and daily volume and we will size the machine and quote it, usually the same day.

Yes, and for FIBC work we insist on it. Jumbo bags vary so much in fabric weight, coating and attachments that a paper specification never tells the whole story. Bring or courier a sample lot of your bags to our works at Andheri East, Mumbai; we run them through the machine, agree the feed method (folded whole or sectioned), and check the output strip against what your raffia buyer wants — then quote the configuration that produced it.
