Is it all cold?

Yes Cold transportation is the whole process of cold transportation, because SF is the whole process of freezing service launched by SF, aiming at ensuring the delivery time and product quality of fresh express mail. This service is aimed at the express delivery of processed food and primary agricultural products (products transported in cold storage/freezing/deep freezing) with a single piece not exceeding 15kg (including packaging materials), and allows the operation of mother and child pieces, with a single ticket not exceeding 50kg (including packaging materials). The consignment temperature zone includes cold storage, freezing and deep freezing, so it is transported by cold in the whole process.
