Flexible pouches are multilayer film structures composed of many different types of material held together by laminating adhesives and heat seal coatings. Flexible pouches have rapidly grown in popularity in the packaging world due to the publics growing interest in waste reduction as well as being extremely functional for the food and beverage industry. The requirements of a flexible pouch varies based on what is being packaged inside.
For instance, many beverages are filled into a pouch while still boiling hot from sterilization. Another common practice is to steam sterilize packaging prior to filling with food contents. In both of these cases the flexible pouch, and thus the adhesives and coatings used to manufacture it, must be able to withstand incredibly harsh production environments.
