Flexible films and pouches are manufactured using a variety of polymer materials, including polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), and polyamide (PA). These materials are often combined in multilayer laminates to achieve specific performance characteristics. For example, PE provides moisture resistance, PET offers strength and clarity, and PA enhances puncture resistance. Multilayer structures also improve barrier properties against oxygen, light, and contaminants, ensuring that the packaged product remains protected and maintains its quality over time.
