A packaging film comprises a base film of at least partially water-soluble plastics film, for example, polyvinyl alcohol, carrying on one side a protective layer of particulate inert plastics material, for example, polytetrafluoroethylene powder, having a high water repellency. The film is thus vulnerable to attack by aqueous media on one side and protected against such attack on the other. It may be used, with the protected side innermost, for unit packaging of detergent compositions, especially liquids containing bleach. In use in the washing machine, the unprotected surface is attacked by the wash liquor to release the contents; the protective layer prevents attack of the package by the contents during storage.
