T/CWIA 1015-2023 stationery thermal transfer film
Basic Information
Scope
Scope: This document specifies the technical requirements such as the performance and safety of thermal transfer films for stationery, as well as the test methods, inspection rules, marking, packaging, transportation, and storage. It also defines related terms and definitions. This document applies to the research, development, production, testing, and acceptance of thermal transfer films for stationery. Main technical contents: The main technical contents include the appearance quality of thermal transfer films, the printing quality and performance of the transfer layer, and safety requirements, along with corresponding test methods: (1) Appearance quality includes items such as the number of joints, the flatness of the film layer, the misalignment between the end of the film roll and the core, the tightness of the film roll, and color deviation. (2) The printing quality and performance of the transfer layer include items such as the dimensional tolerance of graphic units, overprint errors, release properties, surface adhesion, clarity, resistance to friction, resistance to sweat, and antibacterial properties. (3) Safety requirements include items such as the content of migratable elements in thermal transfer films and the content of phthalate plasticizers.
