Once polymerization of ethylene and propylene is complete, the resulting plastic is in a semi-finished form that requires further processing to become high-quality virgin granules.

🔧 Melting and Filtration:

• The polymerized plastic is heated in large extruders to a molten state, ensuring uniform consistency.

• During this stage, the melt is carefully filtered through fine screens to remove any contaminants or impurities. This filtration step is crucial for producing high-purity granules that guarantee a smooth, defect-free end product.

❄️ Cooling:

• The clean, molten plastic is then extruded through a die and immediately cooled—often using a water bath or air cooling system.

• This cooling step solidifies the plastic into continuous strands.

✂️ Cutting into Granules:

• The solidified strands are chopped into small, uniform pieces called virgin plastic granules (usually 2-5 mm in diameter).

• These granules have a consistent melting point, high strength, and excellent processability, making them ideal for injection molding.

📦 Packaging and Shipping:

• The granules are then dried to remove any residual moisture.

• Finally, they are packed in standardized 25–50 kg bags or bulk containers, labeled, and shipped to manufacturers (like Patiala Plastic) for further processing into products such as chairs.
