Plastic Film Shredder for LDPE & BOPP Film Recycling

Yes — both are widely recycled in India. LDPE film shred is agglomerated and pelletized into granules used for new film, pipes and molded products; BOPP recovers similarly within the polypropylene stream. The economics depend on densification: loose film is air, so it must be shredded and agglomerated before any extruder will take it. With EPR placing recycled-content obligations on flexible packaging, organised demand for recovered film material is growing — the recyclers who profit are the ones who can process film without their machines choking on it.

Film has no rigidity, so it never presents a solid face for a blade to bite. In a high-speed machine it slips around the rotor and winds — layer over layer, packing tighter behind the blades, building friction heat until the film half-melts onto the shaft and the motor stalls. Clearing it means knife work and lost hours. A dual shaft shredder avoids the failure mode entirely: two counter-rotating shafts grip the film from both sides and tear it through the gap at low rpm, so there is nothing to wind around and minimal heat.

Feeding is manual: the practical method is to open the bale, slice it into slabs and feed them steadily into the hopper — the shafts pull material down on their own, so the operator paces the feed rather than forcing it. Whether your specific bale slabs feed comfortably depends on bale density and size, which is exactly the kind of thing a trial settles in ten minutes. Bring a bale to our Mumbai works, or ask us about customized models with input conveyors for continuous bale feeding.

Dual-shaft output is an uneven torn shred — that is inherent to grip-and-tear cutting, and it is the correct feedstock for the next stage. Film shred is too fluffy to feed an extruder directly, so film recyclers run it through an agglomerator (densifier) first, which compacts it into semi-dense crumb; that crumb then extrudes into granules. If your buyer is an agglomerator operator or a film recycler, shredded film is exactly what they want delivered — denser to transport and ready for their line.

Dual shaft machines from Raj Electricals have demonstrated shredding of polyester films and laminated pouches, and metallised film is mechanically similar to plain film at the shredder. Two cautions: multilayer laminates are harder to sell as recyclate because of mixed polymers, and any film with heavy print or foil content should be trialled first so you can judge output and confirm your buyer accepts it. For predominantly laminate streams, see our dedicated laminates and lamitube shredding solution.

Dual shaft drives are modest for industrial shredders — one reason these machines suit continuous film duty. Actual units consumed depend on load and feed pattern; we give you the motor rating for your selected model so you can estimate against your electricity tariff. The machine is built to run 24 hours continuously, so a single-shift or double-shift operation is well within its duty envelope.

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 with film we actively encourage it, because gauge, bale density and contamination change machine behaviour more than any spec sheet shows. Bring a sample bale of your LDPE, BOPP or mixed film to our works at Andheri East, Mumbai, for a live trial; outstation buyers can request a video trial on their material. Export orders are supplied with motors matched to your country’s voltage and frequency. Contact us to book a slot.
