High-Purity PET
Material Sorting
Before Color Sorting
MAS-P removes PVC, PP, PE and other non-PET contaminants from PET flake streams, delivering ultra-pure PET for higher product quality, stable downstream performance and maximum value recovery.




Feed
Mixed PET flake stream with possible non-PET contaminants.
Identify
High-resolution detection identifies PVC, PP, PE and other non-PET materials.
Accept / Reject
Contaminants are rejected and pure PET continues to color sorting.
Why MAS-P
Purity that visible color sorting alone can't reach.
MAS-P is the PET material-sorting platform for prepared flakes, where a color-correct flake can still be the wrong polymer.
Material identity, not just color
Targets whether a flake belongs in the PET stream, catching pieces that look right but are the wrong polymer.
Higher PET purity
Removes the selected non-PET pieces so the accepted PET stream can meet a tighter resin specification.
Color and material kept separate
Keeps visible color cleanup and material identity as distinct, staged decisions instead of one blurred step.
Sample-led reject classes
Reject classes are built from your real PET and non-PET examples, not a generic universal material list.
Named contaminant targets
PVC, PE/PP caps, transparent look-alikes and engineering plastics are defined as concrete, testable targets.
Line-ready
Reviewed against your upstream washing and drying and your downstream quality-control needs.
Main applications
Two PET purification jobs, one platform.
MAS-P is positioned by the material target — what must leave the PET stream — not by a vague plastic category.

Application 01
PET purification after washing
Take washed, dried PET flakes and remove the selected non-PET pieces — PVC, PVC sheet, PE and PP caps and closures — so the accepted stream meets your resin spec.

Application 02
Removing look-alike contaminants
Catch the hard cases — transparent non-PET and engineering plastics that pass a color check but are the wrong material — from blue-white and commercial PET feed.
Corriente de purificación PET
Entrada PET, escamas PET aceptadas y rechazos no PET.
El MAS-P se centra en la clasificación de material de escamas PET donde la clasificación por color visible por sí sola no es suficiente para definir la calidad objetivo.

La separación de material debe confirmarse con muestras representativas. No asuma detección universal de polímeros a partir de redacción genérica.
Raw materials
PET and the non-PET classes MAS-P removes.
Switch between purification stages and click any class to see exactly what enters and what leaves — the feed, the accepted PET and each named reject class.
PET versus the common non-PET pieces in a washed flake stream.

Mixed feed
Washed PET flakes arriving with the everyday non-PET pieces — caps, closures and stray polymers — mixed in.
Accepted and reject classes are always confirmed on your representative samples before a configuration is quoted.

The platform
A PET material-sorting platform, sample-led by design.
Stable flake presentation, material-aware inspection and precisely timed ejection are tuned to the accepted PET and non-PET classes you confirm in testing.
Cómo funciona
La clasificación de material comienza después de la preparación de escamas.
El conjunto útil de pruebas incluye PET aceptado, rechazos objetivo, variación de color, residuo de etiqueta, suciedad y tamaño típico de partícula.
- 01Customer-prepared
Feed prepared flakes
Washed, dried PET flakes are metered onto the feeder after your preparation line. Moisture, label residue and flake size all affect how cleanly each piece presents.
- 02Stable presentation
Spread & singulate
Flakes are spread into an even, thin layer so each piece is inspected on its own rather than as a clump — the basis for a consistent material decision.
- 03Material inspection
Read material response
Each flake is inspected for material response, not just visible color. This is what separates a PET flake from a look-alike PVC, PE or transparent non-PET piece.
- 04PET vs non-PET
Decide against the sample map
Every flake is matched to your accepted PET range and the named non-PET reject classes confirmed in the sample test — PVC, PE/PP caps, transparent and engineering plastics.
- 05Air ejection
Eject & verify
Off-PET pieces are blown into the reject channel while accepted PET falls through. Both streams are checked against your purity target, with a second pass available for tighter specs.
Technical details

Six channel modules cover PET purification lines from compact recovery routes to higher-throughput flake plants.

Buyer questions
What buyers ask before specifying a MAS-P.
Straight answers on purity, what counts as non-PET, where MAS-P sits in the line, and how a sample test becomes a configuration.
¿Es MAS-P solo una clasificadora por color?
No. MAS-P se enmarca alrededor de la clasificación de material para escamas preparadas, especialmente la revisión de eliminación de no PET en escamas PET.
¿Puede MAS-P eliminar todo material no PET?
No debe hacerse una promesa universal. La detectabilidad depende de la configuración seleccionada y las pruebas representativas de muestras.
¿MAS-P reemplaza a MAS-C?
No siempre. MAS-C se centra en la clasificación por color visible. MAS-P se centra en la separación de material. Algunas líneas pueden necesitar revisión por etapas.
¿Es MAS-P para botellas enteras?
No. Las botellas enteras deben revisarse bajo MAS-B antes de convertirse en escamas.
Real sample testing
Use your own PET flake stream before finalizing the sorting direction.
A MAS-P project should start from real PET flakes plus the non-PET classes that must be removed from the accepted stream.
