PET thermoform tray recycling knives and granulator blades

Typical thermoform line problems behind the RFQ

  • •Tray flakes turn dusty or stringy after the last knife change
  • •Skeleton regrind gets noisy and bed-knife wear is uneven
  • •The buyer needs replacement knives from a worn sample without a full OEM drawing

Why PET thermoform recycling needs matched rotor and bed knives

NAPCOR notes that PET bale specs now cover PET bottles, bottles with thermoforms, and PET thermoforms, and that trays and clamshells can be recycled when collection and processing systems are in place.

Where these knives sit on tray and skeleton lines

Rapid ThermoPRO is described for low-noise granulation of thermoformed skeletal waste with easier knife replacement access. Compare plastic granulator knives, bed knives, and crusher blades.

What to send for a thermoform knife quotation

Send tray material, sheet thickness, machine model, moving/fixed knife position, dimensions, hole pattern, and old blade photos. If dust or noise increased, review the knife-gap checklist and use the contact form.

PET thermoform tray recycling knives FAQ

Can PET trays and clamshells be recycled?+
NAPCOR says PET clamshells, trays, cups, and similar non-bottle packaging can be recycled if the right collection and processing systems are in place.
Which knife positions should be checked when tray regrind gets dusty?+
Inspect the rotor knife and bed or stator knife together, because fines and noise often come from the stationary edge or clearance, not only rotor steel grade.
Can you quote from a worn thermoform knife sample?+
Yes. Send old knife photos, key dimensions, hole spacing, sheet thickness, machine model if known, and whether the blade is moving or fixed.
