Import Glow In Dark Films — Buy in Bulk from Supplier in China

Derflex produces a glow in dark film that relies on rare earth element activation combined with alkaline earth aluminate to create a phosphorescent surface. The material is non‑toxic, non‑radioactive and chemically stable, making it suitable for long‑term indoor use. It is supplied as a digital printing film that can be cut or printed directly onto flat substrates.

In the broader market such films are typically delivered in thicknesses around 0.05 mm and on rolls up to 1000 mm wide, which balances flexibility with handling ease. The film charges under low light levels; a minimum illumination of 25 lx will initiate phosphorescence, while typical building lighting of 500‑600 lx fully energises the surface. Standard operating temperatures range from - 20 °C to 60 °C and indoor service life can reach twenty years, whereas outdoor exposure is usually limited to seven years due to UV degradation.

Derflex markets the product for fire‑safety signage, ship safety signs and general orientation or identification uses. Importers benefit from the supplier’s harbour‑tier verification and the ability to order bulk rolls, although the listing does not disclose a minimum order quantity or specific incoterms. Prospective buyers should confirm packaging details, lead times and any required test reports before finalising a contract.
