Functional masterbatches and easy-peel materials are core additives and modifying agents that enhance the performance of food and industrial packaging films, widely compatible with substrates such as PE, PP, PA, PS, and PET. In food packaging films, functional masterbatches can impart properties such as smoothness, anti-stick, antibacterial, anti-fog, UV resistance, and freshness preservation, effectively extending the shelf life of fresh, cooked, and dairy products, while meeting food contact safety standards. Easy-peel materials ensure reliable sealing, easy peeling, no residual adhesive, and no leakage, suitable for applications such as cup lid films, cooked food packaging, and steam bags, improving user experience. In the field of industrial packaging films, functional masterbatches provide properties such as antistatic, smoothness, toughness enhancement, and weather resistance, meeting the protection needs of electronics, chemicals, and component packaging. Modified easy-peel materials are used for protective films and sealing films, achieving both convenient peeling and protection. The synergy of these two types of materials optimizes packaging sealing, safety, and convenience, promoting the upgrade of flexible packaging toward efficiency, sustainability, and intelligence.
