PET Recycling Machine
Polyethylene Terephthalate (PET) is one of the most widely used plastics globally, found in beverage bottles, food packaging, textile fibers, and industrial components—but its recycling presents unique challenges, including contamination from labels, caps, and adhesives, inconsistent pellet quality, and low processing efficiency. Traditional PET recycling machines often struggle with incomplete melting, high impurity content, and excessive energy consumption, resulting in subpar regrind that fails to meet downstream manufacturing standards. The PETG-1200 Industrial PET Recycling Machine solves these pain points as a high-performance PET granulator, integrating a double-stage extrusion system, precision cleaning module, and automated sorting technology to convert post-consumer and post-industrial PET waste into high-purity pellets. Designed for large-scale recycling facilities, packaging plants, and textile factories, it delivers exceptional output, reduces operational costs, and ensures full compliance with global environmental regulations such as PPWR, CE, and ISO 9001.
Core Features & How It Solves Your PET Recycling Challenges
Engineered for industrial-scale reliability and performance, the PETG-1200 PET recycling machine focuses on resolving the key pain points of PET waste processing:
- Double-Stage Extrusion System:Equipped with a primary crushing stage and secondary extrusion stage, the machine ensures complete melting and homogenization of PET waste, eliminating air bubbles and impurities. This results in high-density, uniform pellets with a melting point of 250-260℃—matching the quality of virgin PET and suitable for injection molding, fiber production, and packaging manufacturing.
- Automated Contamination Removal:A built-in pre-cleaning system (including label peeling, cap separation, and water washing) removes 99.5% of non-PET contaminants (labels, caps, paper, and adhesives) before processing. This reduces manual sorting labor by 70% and ensures the final regrind meets food-grade and industrial-grade purity standards.
- High Output & Energy Efficiency:Powered by a 45 kW high-efficiency motor, the PETG-1200 delivers a stable output of 800-1200 kg/h of high-quality PET pellets. Its inverter control system and heat recovery technology cut energy consumption by 25% compared to single-stage PET granulators, translating to annual savings of over $18,000 for facilities processing 15 tons of PET waste daily.
- Compliance & Versatility:Fully compliant with PPWR regulations, CE certified, and ISO 9001 approved, the machine is compatible with all types of PET waste, including beverage bottles, food containers, PET fibers, and post-industrial scrap. It also meets FDA standards for food-contact applications, expanding market access across Europe, North America, and Asia.

FAQ (Frequently Asked Questions)
- How to choose a PET granulator for large-scale bottle recycling?Choose a double-stage PET granulator with a pre-cleaning system, motor power ≥40 kW, and output capacity ≥800 kg/h.The PETG-1200 is ideal, as it removes contaminants automatically, delivers high-purity pellets, and complies with global industry standards.
- What is the difference between single-stage and double-stage PET granulation?Single-stage granulation crushes and melts PET in one step, leading to uneven pellets and impurities, while double-stage granulation separates crushing and extrusion for better homogenization and purity.The PETG-1200’s double-stage system ensures consistent pellet quality suitable for high-value applications.
- Can the PETG-1200 process PET waste with labels and caps attached?Yes. The machine’s automated pre-cleaning system peels labels, separates caps, and washes contaminants, removing 99.5% of non-PET materials.This eliminates manual sorting and ensures the final pellets are high-purity.
- How to maintain the PET recycling machine to ensure long service life?Clean the extrusion die and screen mesh daily, inspect and replace tungsten carbide blades every 6-8 months, and lubricate the rotor and extrusion system monthly.We provide a 1.5-year warranty, on-site maintenance, and affordable replacement parts.
