The packaging industry is one of the largest sectors for the consumption of polymer products, utilizing films, containers, bottles, closures, and various forms of flexible and rigid packaging to protect and preserve goods. Key characteristics of these products include transparency, strength, printability, aesthetic appeal, and resistance to environmental factors. Depending on the specific product, polymer raw materials are blended with masterbatches and additives and then shaped using processes such as blown film, cast film, injection molding, blow molding, and extrusion. Finally, the product undergoes cooling, stretching, printing, lamination, cutting, or sealing to become ready for use.
