PET Pellets Application

Bottle-to-package
Post-consumer PET bottles are produced through specific processes; recycling,washing, sorting, pelletizing extruding, thermoforming to produce packaging products such as fruit and vegetable boxes, daily necessities boxes, electronic product packaging boxes, etc.

Bottle-to-filament
Post-consumer PET bottles are recycled into micro denier filament through crushing, washing, pelletizing, and spinning processes.
The products made by micro-denier filament are more flexible, skin-friendly, and eco-friendly.

Bottle-to-bottle
Post-consumer PET bottles are recycled into rPET flakes, The regenerative food-grade PET flakes conform to the quality index requirements of downstream food packaging and are used for bottle blowing and packing which can directly contact food after pelletizing and SSP processes in the late stage(FDA Approval).

PP/PE pellets application:

The PP/PE plastic washing line is mainly used to recycle plastic products used in daily life so called "PCR".

Through the selecting, crushing, washing and pelletizing, the clean and reusable materials are obtained for down-stream for various plastic products, such as building templates, corrugated pipes, hollow pallets, photovoltaic floating barrels, etc. which can realize "PIR".

This way not only reduces carbon dioxide emissions, but also reduces energy consumption.

Recycling Process Flowchart

How to remove woods from PP/PE flakes?

The dynamic centrifuge
The dynamic centrifuge can be used to centrifugally squeeze the crushed wood from HDPE water and prepare them for the drying stage.

From the centrifuge, the product is fed by a pneumatic transport system to the accumulator cyclone.

Contaminants washed with HDPE crushed grains settle on the bottom and grids of centrifuges. The resulting sediment is removed from all baths and centrifuges periodically when they are completely drained.

Function

The dynamic centrifuge is a centrifugal plastic washer used in different applications to wash, dry and separate many flexible or rigid materials.

The centrifugal effect of the plastic waste washing machine is based on mechanical friction combined with the use of a big quantity of water in order to guarantee a very good cleaning effect of the product.

For less contaminated materials the plastic washing machine can be used as "dry separator .

The dynamic centrifuge is also very efficient in the separation of the super absorbent polymer (SAP) from cellulose in the recovery process of absorbent products.
