ABSTRACT:
Semicrystalline polymers and copolymers having migratory additives therein can be provided with reduced migration. A surface layer of the polymer of copolymer article is rendered quasi-amorphous and a film less penetrable by said migratory additives than the polymer or copolymer is adhered thereto.
