Achieving over 98% efficiency with a PET label remover isn’t magic; it’s a result of precise mechanical engineering. Removing the wrap-around PVC/PS/OPP labels is one of the most critical steps for ensuring final PET recycling purity, and a high efficiency de-labeler uses a multi-stage attack.

The Process Inside:

  1. Infeed & High-Speed Rotation: Bottles are fed into a horizontal chamber where a central shaft spins at high RPM (revolutions per minute).
  2. Blade Design: Hundreds of specialized alloy or carbide-tipped blades are mounted on the rotating shaft. A second set of stationary blades is mounted on the chamber’s inner wall.
  3. The “Tornado” Effect: As the shaft spins, the bottles are thrown outwards by centrifugal force. The rotating blades catch the edge of the labels and rip them, while the fixed blades create a counter-force, peeling the label off the bottle’s surface. This creates a turbulent, tornado-like action inside the chamber.
  4. Separation: The main chamber is perforated. The lighter, smaller label fragments are thrown through these perforations and are vacuumed away by a blower into a collection cyclone. The heavier, largely intact bottles continue along the chamber and exit at the end.

It’s this intense, controlled mechanical friction between bottle, rotating blade, and fixed blade that allows the plastic bottle label separator to achieve such a high removal rate in a matter of seconds.
