GB/T 24286-2009 specifies the technical requirements, test methods, and inspection rules for black light-proof packaging paper, which is designed to block visible light and protect light-sensitive materials. It is primarily applied in the packaging of photographic films, photosensitive papers, and other light-sensitive products in the imaging and printing industries, ensuring their quality during storage and transport. The standard also applies to contexts where opaque wrapping is needed to prevent light-induced degradation, such as in laboratory or industrial settings handling photosensitive chemicals.
