Plastic Carry Bag Shredder Machine for Poly Bag Recycling

Yes — LDPE and HDPE film is one of the most reprocessed plastics in India. Once shredded, washed where needed and agglomerated, the material extrudes into reprocessed granules used in pipes, sheets, new film and molded goods. Film reprocessors and agglomerator operators buy shredded bag material by the tonne; what they will not buy is loose, unsorted bags, because the handling cost exceeds the material value. Shredding is the step that converts a storage nuisance into a tradeable raw material.

Three behaviours: film floats, wraps and stretches. In a high-speed blade grinder, near-weightless bags ride the air current above the blades instead of entering the cut; whatever does catch tends to wrap around the rotor shaft in layers until the motor stalls; and stretchy PE film absorbs blade impact instead of fracturing the way rigid plastic does. A dual shaft shredder avoids all three by gripping the film between interlocked, counter-rotating blades and tearing it through at low speed — see how the dual shaft platform works.

No — shred first, wash after. Washing whole bags is impractical: they trap water, nest inside each other and refuse to dry. The standard line order is sort, shred, then wash the shredded film, because small strips wash and dry far more efficiently. What you must do before shredding is remove non-film contaminants — stones, metal, glass and wet organic waste — both to protect the blades and to keep the output saleable. Clean retail and mall bags often skip washing entirely and go straight to agglomeration.

Mechanically, a dual shaft shredder tears both — the cutting action does not distinguish PE film from PP fabric. The issue is downstream: PE and PP are different polymers, and a mixed shred sells at mixed-plastic prices, while segregated streams each fetch more. If your collection is dominated by non-woven bags, the dedicated non-woven bags shredder with a sorted PP-only stream earns better realisation. Most dry-waste centres sort by bag type first and shred in campaign runs — same machine, separate batches.

Work from your daily film intake in kilograms. We size the dual shaft model against that figure so an 8-hour shift clears your intake with steady feeding — comfortably ahead of most ward-level DWCC film volumes, which leaves headroom for growth or second-shift aggregation. Remember that loose bags feed slower than their rated weight suggests because of their volume, so practical throughput depends on feeding discipline. Send us your daily intake and we will size the machine — or walk through our machine selection guide first.

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. Collection-centre material varies enormously — moisture, dirt load, bag mix — so we run trials on your actual material at our works in Andheri East, Mumbai. Bring a representative gunny or two from a normal collection day, not a cleaned-up sample, and you will see realistic feeding behaviour, throughput and output. For municipal tenders we can also document the trial results for your file. Contact us to book a slot.
