Professional guidance for HDPE sheets:
HDPE sheets are engineering plastics made from high-density polyethylene, which is a thermoplastic polymer extracted from petroleum. Polyethylene sheets are odorless, non-toxic, and have a wax-like feel. They have excellent low-temperature resistance (up to -70~-80°C), good chemical stability, and can withstand most acids and alkalis. They are insoluble in general solvents at room temperature and have a low absorption rate. HDPE sheets also feature mold resistance, making them suitable for food processing and storage.
