Polystyrene PS Film for cup sealing food packaging
2024-06-06 17:20PS polystyrene film
PS film has high transparency and glossiness, beautiful appearance, and good printing performance; Low water absorption, high permeability to gases and water vapor. Unstretched polystyrene film is hard and brittle, with low extensibility, tensile strength,and impact strength, so it is rarely used as a flexible packaging material. The main packaging materials used are biaxially
oriented polystyrene (BOPS) film and heat absorption film. The BOPS film prepared by biaxial stretching has significantly improved its physical and mechanical properties, especially elongation, impact strength, and toughness, while still maintaining its original transparency and glossiness. The good breathability of BOPS film makes it very suitable for packaging fresh foods such as fruits, vegetables, meat and fish, as well as fresh flowers.
