Cardboard Shredder Machine and Corrugated Box Shredder

There is no single best shredder, only the right fit for your boxes and your volume. For cartons and corrugated boxes in volume, the usual fit is a slow, high-torque dual shaft shredder: its interlocked shafts grip folded and flattened board and tear it into strips. For one box stream that runs every day, a customised corrugated box shredder is worth discussing. If the board is PP corrugated and you want to sell flake, add an RE grinder after the shredder. A trial on your own boxes is what decides.

We quote every cardboard shredder to the job, so there is no list price. The price depends on the size of your boxes and sheets and how they arrive (loose, flattened or baled), your daily volume and the model and motor it calls for, whether you need strips only or PP flake as well, and the feeding and discharge arrangement you want. Send us a photo of your boxes and your daily quantity and we will recommend a machine and quote it.

It depends first on the type of machine, then on the model. A dual shaft shredder, a single shaft shredder and a grinder are built differently and priced differently, and within each range the capacity and the motor set the price. Your material, MS or SS construction, options such as a blower, a conveyor or a control panel, and how you feed and discharge the machine also count. Our guide to industrial shredder machine price explains each factor, and we quote every machine to your material and volume.

Yes, fully. PP corrugated sheet is plain polypropylene formed into a twin-wall fluted profile. There is no coating or mixed polymer to separate. Once shredded and ground into flake, it goes to PP reprocessors who pelletize it for moulding and compounding, the same route as crate or cap regrind. The reason so much of it still ends up dumped is purely logistical: whole sheets are too bulky to transport economically. Shredding solves exactly that. See our PP plastic shredder page for the wider polypropylene picture.

Strip the fittings (metal eyelets, frames, clips), then shred and grind the sheets into PP flake. This does two things at once: the printed branding is destroyed, important when campaign or brand material must not resurface, and the polypropylene becomes a saleable commodity instead of a tipping-fee liability. Agencies and brand teams handling seasonal surges often shred in batches, and a mid-range dual shaft machine clears that volume batch by batch. Send us your estimated tonnage for a line recommendation.

Converters generate a steady, predictable stream (trim strips, punching skeletons and reject sheets) so size against your daily scrap weight rather than peak season. Weigh a typical day’s offcuts and divide by your shredding window: most converters land comfortably within a mid-range dual shaft machine, with an RE-series grinder downstream if you sell flake rather than shred. High-volume converters can discuss a customised corrugated box shredder. Our machine selection guide walks through the sizing.

PP reprocessors and compounders buy clean corrugated flake to pelletize into reprocessed granules, which go into moulded products, sheets and compounds. Because sunpack sheet is single-polymer and usually clean, its flake is an easy sell compared with mixed plastic scrap. Printed sheets fetch slightly less than unprinted, and consistent flake size from a screened RE-series grinder earns better rates than coarse shred. If you accumulate enough volume, reprocessors will collect from your premises on contract.

Yes. Courier or bring representative material (cartons, printed signage, sunpack offcuts, folded boxes) and we will arrange a trial. A trial settles the questions a spec sheet cannot: how your specific board feeds, what the shred looks like, and what throughput you really get. Contact us to arrange one before you finalise any purchase.
