Conventional plastic materials including HDPE, LDPE, LLDPE, PET and PP remain the backbone of modern packaging and industrial applications. HDPE is widely used for construction vapor barriers, geomembranes and heavy-duty packaging due to its high toughness and waterproof performance. LDPE and LLDPE dominate flexible packaging fields such as stretch films, agricultural films and composite sealing layers, offering excellent flexibility and puncture resistance. Meanwhile, PET continues to lead food-grade packaging for disposable beverage cups, blister packs and transparent packaging sheets, while high-barrier EVOH materials are increasingly adopted for premium food packaging to extend shelf life by blocking oxygen and odor.

Industry analysts predict that the global plastic material market will maintain a CAGR of over 3.2% in the next five years. Functional, food-safe, recyclable and high-barrier plastic products will become the mainstream of international trade, bringing new development opportunities for professional plastic film and sheet manufacturers.
