Infrared (IR) spectroscopy
Identification of materials, contaminations, additives, laquers, adhesives, adhesive-based anti sealing effect etc. with different techniques depending on sample and problem
In short — AI-generated
Infrared (IR) spectroscopy is used to identify the chemical composition of packaging materials, including polymers, adhesives, lacquers, and potential contaminants. The test involves exposing the sample to infrared radiation, which is absorbed by the material's molecules to create a unique spectral fingerprint.
The resulting spectrum allows for the precise identification of materials and the detection of additives or unwanted substances. In practice, this method is essential for quality control, verifying material specifications, and troubleshooting issues like unexpected sealing behavior or surface contamination.
