Polyvinylidene chloride (PVDC) is widely used in packaging materials due to its excellent barrier properties against moisture, oxygen, and aromas. It is commonly applied as a thin coating on films, sheets, or containers to extend the shelf life of food products, such as snacks, meats, and dairy items. PVDC is also utilized in the pharmaceutical industry to protect sensitive medications from environmental factors. Additionally, it finds applications in the production of household wraps and industrial films, where its durability and resistance to chemicals are highly valued. Its ability to maintain product freshness and integrity makes it a critical material in various industries.
