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.

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.
