T/YJC 031-2024 High-performance Recyclable Composite Material Low-temperature Freezer Disc Technical Specification
Basic Information
Scope
Main technical content: The products are classified according to their materials into pure renewable composite freezer trays and composite renewable composite freezer trays, and according to their structures into flat-type and concave-convex type. The technical requirements include that the appearance should be smooth and flawless, with minimal color deviation and clear and firm printing. There are specific specifications for dimensional deviations. The density, mechanical properties (tensile strength, bending strength, impact strength), and hardness vary according to the type of tray. The low-temperature resistance should not deform at -18°C, and the dimensional change rate should be limited. The hygiene performance must meet relevant national standards, and the environmental performance requires that the composite materials contain no harmful substances and meet the standards for heavy metal content. Corresponding to each technical requirement, the test methods specify the detection methods and standards for appearance, dimensional deviations, density, mechanical properties, hardness, low-temperature resistance, hygiene performance, and environmental performance, providing a comprehensive scientific basis for the production and inspection of high-performance renewable composite freezer trays.
