Flexible packaging materials—films, foils, laminates, and pouches—are essential in food, cosmetics, pharmaceuticals, and other sectors due to their lightweight structure, barrier properties, and ability to adapt to different product shapes. These materials typically consist of multilayered compositions combining polymers, metals, or paper to achieve specific protection goals—such as blocking oxygen, moisture, or UV light.

This complexity creates technical challenges. Each layer must perform properly, and poor compatibility between layers can lead to delamination, poor sealing, or migration of substances into the product. Furthermore, production variables like temperature and humidity can impact material performance on the packaging line.

At Pack-Lab, we provide in-depth support to flexible packaging manufacturers, helping them troubleshoot common issues during converting or application on packaging lines. Our services also ensure their materials comply with food and cosmetics regulations, such as EU and FDA standards. We assess mechanical strength, seal integrity, migration risks, and barrier efficiency. Whether you’re qualifying a new supplier or resolving a packaging failure, we help secure compliance and optimize shelf life.
