A method of sealing an air-bag (1) is disclosed, the air-bag having a gas flow duct (4) and a plurality of inflatable cells (5), with each cell (5) having a mouth (6) fluidly connecting the cells (5) to the gas flow duct (4). The method involves inserting a sleeve or "parison" of deformable sealant material (8) into the gas flow duct (4), and then blowing a propellant gas into the sleeve (8) so that the sleeve (8) inflates to form a bubble (12) of sealant material in the region of at least one mouth (6) of a cell (5). The propellant gas is blown into the sleeve (8) until at least the or each said bubble (12) bursts, so as to form a sealant layer on the interior of the air-bag (1) in the region of the respective mouth (6).
