ABSTRACT:
A wc disposable ostomy bag has a wall formed from an inner layer of polyethylene and an outer layer of polyvinyl alcohol. Two flexible layers of aluminum are located between the inner and outer layers to reduce odor transmission through the wall. The material of the walls may be formed by vapor depositing the aluminum layers on respective faces of the inner and outer layers and then laminating the inner and outer layers together with the aluminum layers facing one another. Alternatively, both aluminum layers may be deposited on the same one of the inner or outer layers with a thin non-metallic layer between them to prevent the aluminum layers having common grain boundaries.
