Start With the Material Form

Different Plastics
Hold Water Differently

Rigid flakes, PET flakes and flexible film require different moisture-reduction methods after washing.

01 · Bottle recycling

PET Flakes

RecommendedMechanical Dewatering + Drying

PET flakes can be mechanically dewatered before additional drying when lower residual moisture is required.

02 · Rigid recycling

HDPE / PP Rigid Flakes

RecommendedHorizontal Dewatering / Mechanical Drying

Rigid flakes release free water efficiently through mechanical dewatering.

03 · Flexible material

PP / PE Film

RecommendedDewatering + Film Squeezing

Flexible film retains more water and often benefits from squeezing after mechanical dewatering.

04 · Industrial flexible material

Woven Bag / FIBC Material

RecommendedDewatering + Squeezing

Soft woven PP material requires moisture reduction and compaction before downstream pelletizing.

Moisture Reduction Process

Mechanical Dewatering
Comes First

In most recycling lines, free water is removed mechanically first, with squeezing or additional drying added according to the material and downstream requirement.

For film and woven materials, squeezing can also increase bulk density and help stabilize downstream extrusion feeding.

PET flakes follow a similar route: dewatering first, then drying as required for the next process.

Mechanical firstMechanical moisture removal is generally more efficient for removing free water before any additional drying stage.

Configure for the next stepThe correct moisture-reduction process depends on material form, the upstream washing process and what happens next — storage, transport or pelletizing.

Moisture control continues into downstream extrusion and pellet handling.
