Raman Analysis of Laminated Food Packaging Film: Understanding Diffusion of an Additive. A white paper.

As the sophistication of food packaging systems increase, incorporating combinations of polymer/plastics, paper and foils tailored to a desired design and function, it is becoming increasing important to understand how the food product interacts with the packaging material. This is vital to ensure consumer safety and understanding the performance of the product over the recommended life cycle. In this Intertek white paper, Intertek Materials and Packaging Testing Expert, Dr Gary Johnson, discusses how the application of Raman spectroscopy, in conjunction with accelerated aging studies, is well suited to exploring the interaction of a food product with the laminated polymer films of commercial heat seal bags.
