Multi-layer polymer films can be an important part of maintaining product integrity. Products from food, pharmaceuticals, consumer products, etc. are delivered in polymer film packaging. These films can be important for preventing exposure to oxygen, ultraviolet illumination, or other environmental factors depending on the product in question. The design and fabrication of polymer films is typically a complex and costly process that can affect actual and perceived product quality. Therefore, powerful analytical techniques are required that allow insight in the laminate structure, e.g. in case of product failure. FTIR microanalysis allows measuring chemical images of the laminate structure that reveal the chemical composition of each layer.
