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.
PET IV Matters: How Intrinsic Viscosity Affects Performance and Trade Decisions
Understanding Polyethylene terephthalate (PET) 's IV not only helps in selecting the right material for specific applications but also plays a crucial role in international trade, as IV is linked to product classification, HS codes, pricing, and contract specifications.
How Intrinsic Viscosity Shapes PET Performance?
Intrinsic Viscosity (IV) plays a critical role in determining PET(Polyethylene Terephthalate) resin performance, processing behavior, and final bottle and packaging quality. As a key indicator of polymer chain length and molecular weight, IV directly affects mechanical strength, thermal stability, crystallization rate, and melt flow characteristics.
Is PET Material in Storage Boxes Safe — Even for Repeated Food Storage?
Polyethylene Terephthalate (PET) is one of the most widely used plastics in the world. From bottled water and soft drink packaging to food containers and household storage products, PET has earned a reputation for clarity, strength, light weight, and chemical stability. Importantly, it is recognized as safe for food contact by major authorities such as the U.S. Food and Drug Administration (FDA), the European Union (EU), and China’s GB standards.
Made-to-Order Packaging Innovation: How Do You View the Shift from PP to PET?
The made-to-order beverage industry is transforming not only what people drink but also how those drinks are presented. Rising demand for fresh, customizable, and attractive beverages has pushed packaging from a simple container to a key brand and sustainability asset. This shift drives a move from polypropylene (PP) to high-performance PET(Polyethylene Terephthalate) and recycled PET (rPET), reflecting brands’ focus on experience, environmental responsibility, and innovation.
Thermoformed PET Packaging on the Rise: What Makes PET the Preferred Choice
With the growing demand for lightweight, eco-friendly, and high-performance materials in the packaging industry, the thermoformed polyethylene terephthalate (PET) packaging market is experiencing rapid growth.
Why Choose PET? Discover the Fascinating Facts About PET Plastic
Polyethylene terephthalate (PET) is one of the most versatile and widely used plastics globally. Known as PET or PET resin when used for packaging and polyester when spun into fibers, this material plays a crucial role in our daily lives due to its excellent physical properties, recyclability, and wide-ranging applications.
Unlocking PET’s Potential in Cosmetic Packaging: Advantages and Challenges Explained
The 2024 ICPS report predicts the cosmetic packaging market will grow over 6% annually, driven by rising demands for safety and sustainability. With stricter regulations from the EU and FDA, PET stands out for its safety, clarity, and strong recyclability, boosting its market appeal.
Hot-Fill PET Packaging: How Does WK-811 Resin Ensure Quality and Efficiency?
Hot-fill technology remains a trusted method in beverage packaging, balancing sterilization needs with product quality. While glass has been the traditional choice, PET packaging—especially with specialized resins like Wankai’s WK-811—offers an efficient, cost-effective, and sustainable alternative that meets the stringent demands of hot-fill applications.
Building Safe Packaging: An Analysis of PET’s Acid-Base Resistance and Liquid Compatibility
Polyethylene terephthalate (PET) is widely used in the packaging of beverages, foods, and pharmaceutical liquids due to its excellent mechanical strength, transparency, and chemical stability. However, PET exhibits limited stability in highly acidic or alkaline environments. It is generally suitable for packaging liquids with a pH between 4 and 9, where it maintains structural integrity and chemical inertness.
