Hot Filling, Cold Filling and Aseptic Filling: How Beverage Filling Processes Influence PET Packaging
Polyethylene terephthalate (PET) is widely used in beverage packaging because of its lightweight design, transparency, mechanical performance, processability and established recycling pathways.
Rising Attention on Bisphenol A: Understanding PET Material Safety and Application Boundaries
In recent years, global regulations on food contact materials have continued to evolve, with increasing attention from regulators, industry organizations, and consumers toward the chemical safety of plastic products.
Indonesia Updates Food Contact Material Regulation with New Requirements for Food Packaging Safety
On June 23, 2026, the Indonesian Food and Drug Authority (BPOM) issued Regulation No. 11 of 2026 on Food Packaging, introducing updated requirements for food contact materials (FCMs) and substances used in food packaging. The new regulation replaces the previous Regulation No. 20 of 2019 and officially entered into force on June 30, 2026.
Could discarded PET bottles become a future resource for electric vehicle batteries?
A research team from Pennsylvania State University has recently explored a new approach to transform polyethylene terephthalate (PET) plastic waste into synthetic graphite — a material widely used as the anode component in lithium-ion batteries.
Global Reuse Symbol Introduced to Standardize Identification of Reusable Packaging
A new universal symbol for reusable packaging has been introduced to help consumers more easily identify packaging designed for reuse systems, marking another step toward greater consistency in the global transition to a circular economy.
From PET Resin to Packaging: How PET Bottles Help Protect Beverage Quality
When consumers purchase bottled water, soft drinks, juices, edible oils, or other packaged products, they often focus on the contents inside the package. However, the packaging itself plays a critical role in protecting product quality throughout transportation, storage, and consumption. For PET-packaged products, this protection begins with bottle-grade PET (Polyethylene Terephthalate) resin.
From Laboratory Testing to COA: How PET Resin Quality Is Controlled and Verified
When purchasing bottle-grade PET (Polyethylene Terephthalate) resin, customers often focus on the values listed on a Certificate of Analysis (COA): Intrinsic Viscosity (IV), Acetaldehyde (AA), color, moisture content, and other quality indicators. These numbers play an important role in production planning and quality verification. However, few people consider the extensive testing, monitoring, and quality management activities behind each reported value.
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.
