The cardboard tubes are made from recycled Kraft paper, so the natural color of the tubes is brown Kraft, but we can wrap different color paper onto the tube surface to make colorful tube packaging, on both inside and outside. The brown Kraft surface paper can be simple color printing and look natural. The white art paper is the most used if you want to print a full-color artwork, just like they are used to wrap on other gift boxes packaging because art paper is the best suitable paper for printing to get quality printing result. If you like to have a black color cardboard tube, then need to wrap a matt black Kraft surface paper. Black paper is not an ideal paper for printing, usually only print white ink on it, but they are perfect paper to apply a special finish such as spot UV, hot foil stamping to get a luxury feel packaging.
