The application discloses a flexible multilayer tubular package. The package is for an intermittent catheter. The intermittent catheter is coated with a hydrophilic coating, which becomes slippery when in contact with a swelling medium. Thus, the tubular package of the application can with-hold the swelling medium for a long time and at the same time being flexible and bendable. Furthermore, the application discloses a catheter package set, which comprises a multilayer tubular package, an intermittent catheter and a swelling medium.
