Quick Summary

As sustainability becomes a defining goal in global packaging, recycled PET (rPET) has emerged as the most balanced solution — combining circularity, clarity, and performance. Unlike traditional single-use plastics, rPET utilizes recycled polyethylene terephthalate, reducing carbon emissions and plastic waste. For global businesses, adopting rPET packaging is both an environmental commitment and a market necessity.
DASHAN, a professional food packaging manufacturer with extensive thermoforming experience, integrates advanced rPET technology, quality control, and OEM/ODM export capabilities to provide safe, durable, and eco-conscious PET and rPET packaging solutions for international brands.

1. Introduction: The Global Shift Toward Recycled Plastics

The Global Shift Toward Recycled Plastics

In the last decade, the global packaging industry has undergone a rapid transformation. The shift from virgin plastics to recycled and bio-based materials reflects a growing consensus: sustainability is no longer optional — it’s strategic. Governments, corporations, and consumers alike are demanding packaging that minimizes environmental impact while maintaining functionality.

Recycled PET (rPET), derived from post-consumer PET bottles and packaging, represents the most mature and scalable recycled plastic system in the world. Its closed-loop recyclability and stable supply chain make it the preferred material for beverage cups, food containers, and sushi boxes.
As nations introduce stricter plastic regulations — such as the EU’s Single-Use Plastics Directive, U.S. Extended Producer Responsibility (EPR) programs, and China’s Green Packaging Plan — rPET has evolved from a sustainability trend into a compliance requirement.

For food packaging producers like DASHAN, this shift offers both opportunity and responsibility: to deliver recycled materials that meet international safety and aesthetic standards, while maintaining production efficiency and global competitiveness.

2. Understanding rPET: What Makes It Different

rPET Cup

rPET, or recycled polyethylene terephthalate, is created through the reprocessing of used PET materials — mainly beverage bottles. While its chemical backbone is identical to virgin PET, the difference lies in the processing history and purification steps that determine its safety and clarity.

Production Process

  1. Collection and Sorting
    Post-consumer PET bottles are collected through municipal or industrial systems and sorted by polymer type and color.

  2. Washing and Flake Preparation
    The sorted material is crushed into flakes and washed in alkaline solutions to remove labels, adhesives, and contaminants.

  3. Re-extrusion and Solid-State Polymerization (SSP)
    Clean flakes are melted and re-polymerized under controlled temperature and vacuum to restore intrinsic viscosity (IV) — ensuring mechanical strength and safety.

  4. Pelletizing and Sheet Extrusion
    The final rPET pellets are transformed into sheets or films, ready for thermoforming into products such as cups, lids, and boxes.

This advanced recycling process allows rPET to achieve food-grade safety certification under regulations like U.S. FDA 21 CFR 177.1630 and EU Regulation No 282/2008, provided proper decontamination and traceability are maintained.

Key Advantages of rPET

  • Lower Carbon Footprint: Up to 60% fewer CO₂ emissions than virgin PET.

  • Closed-loop Recyclability: Enables continuous material recovery and reuse.

  • High Clarity and Strength: Maintains transparency and toughness comparable to virgin resin.

  • Food Safety Compliance: Compatible with global food-contact standards.

3. Global rPET Policies and Market Trends

The acceleration of rPET adoption is closely tied to policy-driven sustainability frameworks around the world.

Europe

EU rPET Policy Targets

The European Union has set ambitious targets:

  • At least 25% recycled plastic in PET bottles by 2025,

  • 30% by 2030 under the Single-Use Plastics Directive.
    To support these goals, many European brands now source certified rPET packaging to meet compliance and brand reputation requirements.

United States

US rPET

Several U.S. states, including California and Washington, enforce recycled content mandates for beverage packaging — 15% by 2022, increasing to 50% by 2030. The U.S. packaging sector is also moving toward Extended Producer Responsibility (EPR) programs that place financial responsibility for recycling on producers.

Japan

JAPEN PET

Japan leads Asia in PET recycling efficiency, achieving over 85% collection rates through its nationwide bottle return program. The Japanese market emphasizes high-purity rPET for both beverages and food packaging, setting a global benchmark.

China

China rPET

China’s “Green Packaging Development Guidelines (2020)” emphasize recyclable materials, particularly PET, as a core component of the domestic circular economy. The government supports rPET infrastructure expansion, fostering growth in both local consumption and exports.

Global Outlook
