A method of manufacturing an ostomy appliance including: a first wall and a second wall which are connected to each other at or near their peripheries to form a main body having an internal cavity for collecting waste, and an opening, and an outlet portion, formed from outlet layers and having an entrance, which is fluidly connected to the internal cavity, and an exit, which permits waste collected in the internal cavity to be emptied. The method can include attaching the outlet portion to the main body by: positioning the outlet portion, relative to the opening in the main body so that the entrance aligns with the opening, and positioning a soluble member such that the first wall and first outlet layer are positioned to one side of the soluble member and the second wall and second outlet layer positioned to an opposing side of the soluble member.

A fecal catheter or ostomy pouch made of an odor barrier material including a thermoplastic elastomer, odor barrier modifier and an antiblocking agent.

Certain embodiments relate to a soft odor barrier material in a medical device. The soft odor barrier material includes an elastomer and an antiblocking agent. In certain forms, the antiblocking agent imparts an interior rough surface having an arithmetic mean surface roughness (Ra) not less than 0.1 μm. In certain forms, the antiblocking agent is non-blocking upon folding and packaging.
