Abstract

The present invention describes a method for producing a leak-tight vessel for holding a gas and/or liquid, comprising the steps of winding a heat-sealable thermoplastic barrier strip around a removable mandrel in such a way that each strip fragment overlaps with a substantially parallel strip fragment over at least a lateral overlapping distance, consolidating the overlapping strip fragments so as to form a gas and/or liquid tight layer, winding a fibrous material around the gas and/or liquid tight layer, thereby leaving an opening large enough for removing the mandrel. The invention also describes a leak-tight vessel produced in this way.
