A container for odorous material (in the present case an ostomy bag), consists of a front wall (10) and a rear wall (12) welded together around a peripheral seam (14). The walls are made of a plastics material through which odorous gas can permeate. The container carries or contains malodor counteractant material to counter, or mask, the odor. The malodor counteractant material may be provided in microencapsulated form, and coated (at 28) on the interior faces of the walls, or carried on an article (54) placed within the container.
