Recycled PET is becoming more important in the packaging industry as brands look for ways to reduce virgin plastic use and improve sustainability. However, when food-contact applications are involved, the main issue is not only whether rPET is recyclable, but whether it is safe, complian Read More

What is the real difference between low-value recycled PET and premium rPET sheet or film that can run smoothly, form cleanly, and deliver consistent quality? In many plants, the answer is not only raw material sourcing. It is what happens to molecular structure, melt behavior, and process stability Read More

High-strength PET compounds are not built by reinforcement alone. Many PET formulations look promising on paper, yet after drying, melt compounding, pelletizing, and molding, they lose stiffness, become brittle, or process less consistently than expected. The real bottleneck is often not the filler Read More

You deal with three main kinds of hydrolysis in polymers and plastics: acid, alkaline, and enzymatic. Hydrolysis breaks down these materials. This can make them last less time and work worse. Research shows that biodegradable plastics can lose strength fast or slow in the ocean. Read More

The most expensive yarn break is not always the one that stops the line. It is the one that reveals a deeper problem in the polymer itself: lower intrinsic viscosity, shorter molecular chains, weaker melt strength, and unstable spinnability. In PET filament and yarn production, those problems often Read More

Discover how PET chain extender agent helps flexible packaging films achieve better tear resistance, improved melt strength, stable gauge, fewer gels, and more consistent film quality in virgin and rPET film extrusion. Read More

SUZHOU, China, 2026 – With the rapid development of the polyurethane industry towards high-end and multi-scenario applications, hydrolysis has become a key bottleneck affecting the service life and performance of polyurethane products, making high-efficiency hydrolysis resistance agents an indispens Read More

Why do some PET bottles look acceptable at the start of production, then suddenly fail top-load checks, deform during capping, or show inconsistent dimensions from batch to batch? In many bottle plants, the real problem is not only mold design or blow pressure. The deeper issue is that the polymer e Read More
