MAS-PPET MATERIAL SORTING SERIES

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.

01

Feed

Mixed PET flake stream with possible non-PET contaminants.

02

Identify

High-resolution detection identifies PVC, PP, PE and other non-PET materials.

03

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.

When material and color are both hard, step up to the advanced series.

For mixed-polymer streams beyond a PET-focused route, the advanced MAS 3D material series adds broader material recognition for difficult rigid-plastic mixtures.

PET purification stream

PET feed, accepted PET flakes and non-PET rejects.

MAS-P focuses on PET flake material sorting where visible color sorting alone is not enough to define the target quality.

Feed

Material separation must be confirmed with representative samples. Do not assume universal polymer detection from generic wording.

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.

Incoming feed

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.

How it works

Material sorting starts after flake preparation.

The useful test set includes accepted PET, target rejects, color variation, label residue, dirt and typical particle size.

  1. 01
    Customer-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.

  2. 02
    Stable 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.

  3. 03
    Material 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.

  4. 04
    PET 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.

  5. 05
    Air 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.

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.

Is MAS-P only a color sorter?

No. MAS-P is framed around material sorting for prepared flakes, especially PET flake non-PET removal review.

Can MAS-P remove every non-PET material?

No universal promise should be made. Detectability depends on selected configuration and representative sample testing.

Does MAS-P replace MAS-C?

Not always. MAS-C focuses on visible color sorting. MAS-P focuses on material separation. Some lines may need staged review.

Is MAS-P for whole bottles?

No. Whole bottles should be reviewed under MAS-B before they become flakes.

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.
