PET Bottle-to-Bottle Washing Line for Food-Grade Flakes

Product Overview

Our PET bottle washing line is a complete, high-performance system engineered to recycle post-consumer PET bottles into high-purity flakes suitable for food-grade packaging, textile fiber production, and other premium applications. By integrating advanced sorting, washing, and drying technologies, the line efficiently processes mixed, heavily contaminated PET waste — removing labels, caps, adhesives, organic residues, and other impurities to deliver clean, high-quality PET flakes that meet strict hygiene and quality standards.

With capacities ranging from 500 to 3,000 kg/h, the system is designed for scalability and adaptability, making it ideal for recyclers of all sizes. Emphasizing automation, energy efficiency, and minimal water consumption, the line helps reduce operational costs and environmental impact while maximizing output quality.
