Abstract
Container for dry powders, granules, pellets, gas and other ignitable substances and method of producing the same. The container comprises a wall (11-13) formed by a spirally wound profile having an open cross-section, wherein adjacent windings of the profile are attached to each other. According to the invention, the profile comprises a first thermoplastic layer forming the inner surface (11) of the profile and a second thermoplastic layer (12) placed about the first thermoplastic layer and forming the outer surface of the profile, said second layer being antistatic. The present containers have good mechanical strength properties and accumulation of electric charges inside the container can be efficiently avoided. The container can be used, e.g., as a drier for material/powder/pellets.
