What is PSP Foam Sheet?
PSP Foam Sheet (polystyrene foam sheet) is a lightweight sheet widely used in food packaging, building insulation and industrial cushioning materials. Its main raw material is high-quality polystyrene granules (PS granules), which are made through processes such as foaming, extrusion and molding. Due to the characteristics of light weight, impact resistance, thermal insulation and heat insulation, PSP sheets have become an ideal choice for products such as food trays, fast food boxes, cake trays, disposable dishes and so on.
