Abstract
A multilayered container and a process for forming the same are disclosed. The container includes a support wall formed from a plastic having an undesirable substance therein and polymerized to a level less than that necessary to prevent the undesirable substance from migrating from the plastic into the contents when the contents are in contact with the support wall. A protective wall is provided adjacent the support wall and adapted to be positioned between the support wall and the contents. The protective wall is formed from a material which limits the migration of undesirable substance from the support wall into the contents.
