Abstract
In a multilayer flexible film suitable for medical solution packaging, film-derived extractables are controlled by the use of a small amount of a high molecular weight stabilizer in the outer layer of the film. Solution pH can be controlled by the addition of a carbonate of an alkali metal to at least one intermediate adhesive layer and/or the core layer of the film.
