Developed specifically for low-temperature storage environments, this chilled vacuum tin adopts high-density thickened tinplate and composite heat-insulating interlayer technology, delivering excellent cold resistance and temperature control performance. It is suitable for low-temperature storage scenarios such as refrigerators and cold chains. Unlike ordinary tins, it will not crack in low temperatures. The material will not harden or deform in cold environments with stable structure, resisting material aging and cracking caused by temperature differences.

　　The tin is equipped with high-precision vacuum temperature-locking sealing technology. The sealing ring is made of food-grade cold-resistant silica gel, which never hardens or ages in low temperatures and maintains a tight fit. The vacuum structure blocks cold and hot air convection to slow down temperature loss and realize long-term cold preservation. It effectively isolates moisture, dust and peculiar smells to prevent food tainting, dampness and frosting, and avoids corrosion caused by condensed water in low-temperature storage.

　　The surface adopts a low-temperature resistant anti-corrosion coating, which is frost-proof, rust-proof and wear-resistant, keeping smooth and firm in long-term humid and cold environments. The reinforced buckle closure ensures an airtight seal and stable vacuum temperature-locking performance after repeated use. The lightweight and neat body is easy to stack, ideal for cold chain transportation, refrigerator refrigeration and constant-temperature storage. It can store dried fresh food, tea, health products and precision devices. With professional cold-resistant vacuum structure integrating temperature locking, sealing, antifreezing and anti-corrosion functions, it is a high-quality storage container dedicated to low-temperature storage.
