T/CPPIA 35-2024 Flame-retardant polyester film

Scope

Scope: This document specifies the product classification, requirements, test methods, inspection rules, marking, packaging, transportation, and storage of flame-retardant polyester films. This document applies to the production, inspection, and sales of flame-retardant polyester films (hereinafter referred to as "films") made from polyethylene terephthalate (PET) as the main raw material, with the addition of an appropriate amount of halogen-free flame retardants and other additives, and then subjected to biaxial stretching. Main technical content: 5. Requirements 5.1 Appearance 5.1.1 Coiling quality: The film rolls should be coiled neatly, with a smooth appearance, consistent tension, and no obvious longitudinal stripes. The ends should not have obvious star-shaped wrinkles. 5.1.2 Visual quality: The surface should not have obvious cracks, scratches, folds, sagging, wrinkles, blisters, impurities, oil stains, or any defects that affect its applicability. 5.2 Dimensions and deviations 5.2.1 Length, width, and deviations: The length should not have a negative deviation, and the width deviation should be ±2 mm. 5.2.2 Thickness and deviations: The thickness and deviations should meet the requirements specified in Table 1. 5.3 Physical properties: The film properties should meet the requirements specified in Table 2. If the user has other requirements, the product performance requirements shall be determined through consultation between the supplier and the buyer. 5.4 Flame-retardant performance: The flame-retardant performance of VTM-0-grade films should meet the VTM-0 grading conditions, and the flame-retardant performance of VTM-2-grade films should meet the VTM-2 grading conditions.
