T/CPPIA 39-2024 Transfer foil-laminating polyester film for hot stamping

Scope

Scope: This document specifies the terms and definitions, product classification, requirements, test methods, inspection rules, marking, packaging, transportation, and storage for polyester films (referred to as "films") used for hot stamping transfer. It applies to the production, inspection, and sales of electrostatic-free hot stamping transfer polyester films made from polyethylene terephthalate (PET) as the main raw material, with the addition of appropriate anti-blocking agents and other additives, and manufactured by melt extrusion and biaxial stretching. Main technical content: 5. Requirements 5.1 Appearance quality 5.1.1 Rolling quality: The film rolls should be neatly rolled, have a smooth appearance, and consistent tension. There should be no defects such as dead folds, bulging, star-shaped folds at the ends, mechanical damage, or oil stains. The flatness of the ends should be ≤2mm. 5.1.2 Apparent quality: The film surface should meet the requirements for foreign objects and scratches specified in Table 1. 5.2 Dimensions and deviations 5.2.1 Length and width deviations: The length deviation should be a positive deviation, and the width deviation should be ±2mm. 5.2.2 Thickness and thickness deviations: The thickness and deviations should meet the requirements specified in Table 2. 5.3 Physical properties The physical properties should meet the requirements specified in Table 3.
