trinamiX Reflectivity Check
– NIR Reflectivity Testing for Plastic Sortability
Instantly Test Packaging for NIR Sortability – Wherever You Are
The trinamiX Reflectivity Check enables packaging and recycling professionals to swiftly assess if a plastic sample is detectable by NIR sorting systems, helping packaging teams evaluate whether materials are detectable by NIR sorting systems used in recycling facilities — all on-site, without the need for laboratory equipment.
Regulatory Context: Packaging Sortability
Regulatory frameworks are increasing the need for practical verification of packaging detectability in recycling systems. Initiatives such as the EU Packaging and Packaging Waste Regulation (PPWR) and U.S. legislation like California SB343 emphasize that packaging labeled as recyclable must also be effectively sortable in real recycling infrastructure.
Because optical sorting systems rely on near-infrared (NIR) detection, verifying NIR reflectivity of plastic materials during development has become an important step in packaging evaluation. Portable NIR devices enable teams to measure reflectivity directly on packaging samples, helping identify potential sortability issues early in design and prototyping phases.
What Is the trinamiX Reflectivity Check?
An out-of-the-box application and data model operating on the trinamiX PAL One handheld NIR spectrometer. It quantifies the near-infrared light reflectivity of plastic samples, a crucial factor in determining their sortability in recycling facilities.
If reflectivity is too low (typically below ~10%), optical sorting systems may not reliably detect the material. The Reflectivity Check measures this value directly and compares it against reference reflectivity data to support fast sortability assessments.
NIR Reflectivity Database for Plastics
The application uses the “10 Plastics Reflectivity” reference database, a dataset of representative plastic materials used to benchmark NIR reflectivity behavior. By comparing measured reflectivity values against this reference set, the system helps users quickly interpret whether a packaging sample falls within typical detectability ranges for optical sorting systems.
What You Get
This application is perfect for quick prototyping phases and comprehensive recyclability evaluations, providing immediate insights into material sortability.
Why It Matters
While many packaging designs are deemed recyclable in theory, they often fail in practical sorting scenarios due to low NIR visibility. This leads to:
The Reflectivity Check helps you eliminate guesswork, reduce development cycles, and generate trusted evidence — before your packaging reaches the market.

Frequently Asked Questions
FAQ 1: What is NIR reflectivity in plastics?
NIR reflectivity describes how strongly a plastic material reflects near-infrared light. Optical sorting systems in recycling facilities use this signal to detect and identify plastic materials on sorting lines.
FAQ 2: Why does plastic reflectivity matter for recycling?
If a plastic material reflects too little near-infrared light, optical sorting systems may not detect it reliably. Measuring reflectivity helps evaluate whether packaging can be identified and sorted in recycling infrastructure.
FAQ 3: What is the “10 Plastics Reflectivity” database?
The database contains reference NIR reflectivity data for representative plastic materials. It allows measured packaging samples to be compared against typical reflectivity ranges used by optical sorting systems.
