How Polyethylene Terephthalate (PET) Is Expanding Beyond Traditional Beverage Applications

For decades, Polyethylene Terephthalate (PET) has occupied a highly defined position within the global plastics industry. Whether used for bottled water, carbonated soft drinks, or edible oil packaging, PET was primarily developed around the needs of the beverage packaging sector.

How Does the REACH Framework Shape Chemical Governance in the Global PET Industry?

Recent discussions on EU chemicals policy (May 2026) indicate ongoing evaluation of the REACH regulation. While the revision process is still under discussion, the current framework remains fully implemented across the EU. For global industries such as polyethylene terephthalate (PET) resin used in food and beverage packaging, REACH remains a stable chemical regulatory system, defined by consistent application in substance control and supply chain communication.

Large-Format Water Containers: PET vs Polycarbonate (PC)

Large-format beverage containers such as 5-gallon (19L) water bottles are widely used in drinking water distribution systems. The two main materials are polyethylene terephthalate (PET) and polycarbonate (PC). While both can meet structural requirements, they differ significantly in chemical safety, mechanical performance, thermal stability, reuse behavior, regulatory status, sustainability, and cost.

Understanding PET Barrier Performance and Wankai’s Advanced Solutions for Carbonated Beverage Packaging

Polyethylene terephthalate (PET) is a semi-crystalline engineering polymer combining mechanical strength, optical clarity, and chemical resistance with inherently moderate gas barrier properties. In beverage packaging—particularly carbonated soft drinks (CSD)—its commercial performance depends not only on structural integrity, but more critically on its ability to control molecular transport of oxygen (O₂), carbon dioxide (CO₂), and water vapor (H₂O).

Zero Import Duty for PET and Key Chemicals in India, Valid April 2–June 30, 2026

In a move to strengthen domestic manufacturing and ease raw material cost pressures, the Government of India, through the Ministry of Finance (Department of Revenue), has issued Notification No.12/2026‑Customs (G.S.R. 246(E)), implementing a temporary zero‑import‑duty regime for critical industrial chemicals and plastic raw materials. The policy runs from April 2, 2026 to June 30, 2026.

Wankai New Materials | CHINAPLAS 2026 Invitation

With the core theme of "Transformation · Collaboration · Co-Creating Sustainability", CHINAPLAS 2026 is a globally influential grand event in the plastics and rubber industry. It has obtained dual recognition from the Global Association of the Exhibition Industry (UFI) and the European Association of Plastics and Rubber Machinery Manufacturers (EUROMAP), and its influence is second only to Germany's "K Show".

Scientists Engineer Bacteria to Convert PET Plastic Waste into Parkinson's Drug Levodopa

A groundbreaking study published in Nature Sustainability has introduced an innovative engineered microbial system that upcycles polyethylene terephthalate (PET) plastic waste into levodopa (L-DOPA), a first-line medication for Parkinson's disease (PD). This landmark achievement blazes a new trail for sustainable plastic pollution mitigation and green pharmaceutical manufacturing, turning the vision of "converting waste into high-value medicine" into a tangible proof-of-concept.

Is PET Plastic Safe for Heating? Experts Explain the Correct Use of Ready Meal Packaging

A recent report from Greenpeace International has once again brought the safety of plastic food packaging into the public spotlight. The report highlights that plastic packaging can release chemicals and microplastic particles into food when heated—even products labeled as "microwave-safe" or "heat-resistant" are not exempt.

Are Biobased Materials Considered Plastic? New Study Clarifies EU Regulatory Framework

As biobased and biodegradable plastics gain market traction as alternatives to conventional petroleum-based materials, confusion persists over their regulatory status. A recent study offers guidance on how biobased materials are treated under EU law, highlighting that renewable origin alone does not determine regulatory classification.

New study reveals major differences in how bisphenols accumulate in human organs

Scientists use physiologically based kinetic models to increase understanding of bisphenol concentrations in humans upon oral exposure; report significant differences in organ levels and toxicokinetic profiles of bisphenol A (BPA) and its analogues. PET (polyethylene terephthalate), the material widely used for water bottles and food packaging, is chemically distinct from polycarbonate and epoxy resins and does not contain BPA or other bisphenols in its polymer structure.

What You Need to Know About Antimony Migration in PET and rPET Bottles

On January 22, 2026, Dr. Luyu Wang from the University of Illinois at Chicago, together with scientists from the Food Packaging Forum (FPF) and other co-authors, published a comprehensive review in the Journal of the Endocrine Society on antimony (Sb) in food contact materials (FCMs). The review systematically analyzed Sb migration, associated health risks, and guidance for minimizing human exposure.

An Additive-Based Analysis: Why PET Bottles Possess an Inherent Safety Gene？

Within plastic packaging, polyethylene terephthalate (PET) bottles are distinguished by their unique safety profile. This safety stems not merely from stringent post-production controls but is fundamentally embedded in the material's chemistry and a formulation philosophy of "essential minimalism." From an additive perspective, PET's inherent safety manifests through four key attributes.
