Scope

Scope: This standard specifies the terms and definitions, product codes, technical requirements, test methods, inspection rules, packaging, marking, storage, transportation, and product lifespan for cold storage materials and products. This standard applies to plastic cold storage panels composed of cold storage agents and plastic molding materials (plastic boxes) in the food cold chain. Main technical content: 5.1 Raw materials 5.1.1 Cold storage agents: Cold storage agents shall comply with the requirements of T/TJWL 004. 5.1.2 Plastic molding materials (plastic boxes): Plastic molding materials shall be made of materials meeting the requirements for food packaging, and the physical and chemical properties and safety performance of the materials shall comply with GB 4806.7. The external dimensions of the plastic molding materials (plastic boxes) shall be determined according to the relevant application scenarios. 5.1.3 Appearance: The outer surface of the plastic cold storage panels used in the food cold chain shall be clean and tidy, without damage or dirt, without leakage, and the internal liquid shall be clear. The sealing shall be tight, and the dimensions shall meet the requirements. The outer packaging shall be clearly marked and easy to read. If the customer has special marking requirements, they shall be implemented according to the customer's requirements. 5.2 Mechanical and physical properties 5.2.1 Water vapor permeability: The water vapor permeability of the plastic molding materials (plastic boxes) shall be ≤15g/(.24h), meeting the requirements of GB/T 1037. 5.2.2 Tensile strength and breaking strain 5.2.2.1 Tensile strength in the longitudinal direction: ≥18N, in the transverse direction: ≥15N, meeting the requirements of GB/T 1040.3. 5.2.2.2 Breaking strain in the longitudinal direction: ≥200%, in the transverse direction: ≥200%, meeting the requirements of GB/T 1040.3. 5.2.3 Pressure resistance: After the sample is subjected to a pressure test w
