Rationale

The requirement for cannabis beverage manufacturers to know the exact liner material of aluminum cans is critical because different liner chemistries, such as epoxies, acrylics, polyesters, and methacrylates, can interact differently with formulation components, potentially leading to undesired changes. Supplier specifications or visual inspection are often insufficient, making ATR FTIR and Raman spectroscopy valuable tools for rapid, reliable liner identification. These methods enable manufacturers to verify incoming packaging and ensure compatibility between cannabinoid formulations and can materials, reducing the risk of instability.
