High-quality PET flakes are produced through a series of mechanical and washing processes that remove labels, caps, metals, PVC, adhesives, organic contaminants, and moisture from post-consumer PET bottles. A complete PET bottle washing line typically includes bale breaking, sorting, delabeling, crushing, float-sink separation, hot washing, friction washing, rinsing, dewatering, and drying. For bottle-to-bottle recycling applications, PET flakes generally require PVC content below 50 ppm, moisture below 1%, and label contamination below 100 ppm. Proper equipment configuration and process control are essential for achieving food-grade or high-purity recycled PET.

What Are High-Quality PET Flakes?

High-quality PET flakes are clean, dry, and contamination-controlled recycled PET materials suitable for reprocessing into new products.

PET flakes are produced by processing used PET bottles through shredding and washing systems. Their quality directly affects extrusion performance, IV stability, pellet quality, and end-product applications.

Typical applications include:

• Bottle-to-bottle recycling
