DISPOSABLE, MOISTURE VAPOUR PERMEABLE, LIQUID IMPERMEABLE COVERING SHEET CONTAINING ACTIVE AGENTS

摘要

The present invention relates to a disposable covering sheet which is moisture vapour permeable and liquid impermeable and contains active agent or agents. The disposable covering sheet comprises at least a moisture vapour permeable layer and a liquid impermeable but moisture vapour permeable film layer of thermoplastic compositions. The disposable covering sheet such as, for example, a mattress cover or a pillow cover gives a better comfort to the user by providing active agent releasing properties. The disposable covering sheet of the present invention can find a variety of applications wherein moisture vapour permeability and liquid imperviousness combined with long lasting active agent releasing properties are desirable.
