The protective film is applied by vacuum-deep-drawing, coating, spraying, immersion, powder-coating or sintering and maybe coloured. All traces of the film are removed by dissolving it by altering the temperature. USE/ADVANTAGE - The protective film is resistant to the contents of the container and can be dissolved and removed.
