From Waste to Value: The Step-by-Step Process of Producing High-Quality PP and HDPE Flakes

🔄 Turning Plastic Waste into Valuable Materials

The world produces millions of tons of plastic waste every year — and much of it can be recycled and reused.
Through the right process, discarded plastic bottles, containers, and household items can be turned into clean, valuable flakes used for manufacturing new products.

At SJP Company, we specialize in converting PP and HDPE waste into high-quality flakes that meet export standards for industries worldwide.

🧩 Step 1: Collection and Sorting

The journey starts by collecting post-consumer and post-industrial plastic waste.
Each batch is carefully sorted by type and color — separating PP (Polypropylene) and HDPE (High-Density Polyethylene) materials to ensure purity.

Contamination from PVC, PET, or other materials is removed manually and mechanically to maintain consistent quality.

💦 Step 2: Washing and Cleaning

Next, the sorted plastic goes through a multi-stage washing process:

• Cold washing removes dirt, paper, and labels.

• Hot washing uses high temperature and detergent to eliminate oil, glue, and other residues.

• Rinsing and drying ensure the flakes are clean and low in moisture (<1%).

This step is crucial — clean flakes mean better extrusion and pelletizing results for buyers.

⚙️ Step 3: Shredding and Size Reduction

The clean plastic is then shredded into uniform flakes, usually between 10–14 mm, depending on customer requirements.
Uniform flake size ensures smooth melting and mixing during the recycling or manufacturing process.

🧴 Step 4: Drying and Quality Inspection

After shredding, the flakes are dried using air or mechanical dryers to remove moisture.
Then our team conducts manual inspection and testing to check:

• Moisture level

• Color consistency

• Contamination rate

• Bulk density

Only flakes that meet our standards move to the final packaging stage.

📦 Step 5: Packaging and Export Preparation

Finally, the flakes are packed in jumbo bags (1 ton each), sealed, and labeled by grade and color and also can by request.
We ensure every shipment is clean, dry, and export-ready, supported by accurate documentation and inspection reports if needed.

🌍 Why Production Quality Matters

High-quality flakes mean:

• Less downtime during production

• Better extrusion performance

• Lower waste ratio

• Smoother product finishing

That’s why we don’t compromise on our process — each ton of flakes reflects our commitment to quality, sustainability, and reliability.

✅ Final Thoughts

Producing plastic flakes is more than recycling — it’s creating value from waste.
With professional handling, consistent washing, and strict quality control, recycled PP and HDPE flakes can perform just as well as virgin materials.

If your business values sustainability and stable supply, partnering with a trusted producer is the smartest step forward.
