An overmolded thermoplastic article includes a substrate portion molded from a thermoplastic resin compound and an overmold portion molded from a thermoplastic elastomer compound. The thermoplastic resin compound includes thermoplastic polymer resin. The thermoplastic elastomer compound includes thermoplastic elastomer and polysiloxane as a mold release agent, and is free of wax. The overmold portion is bonded onto the substrate portion with a peel strength at least comparable to that of an overmolded thermoplastic elastomer compound containing wax as a mold release agent instead of the polysiloxane. Undesirable effects observed with the use of wax as a mold release agent in overmolded thermoplastic elastomer compounds such as blooming and ease of scratching/marring can be reduced, while desirable properties such as silky feel of the surface of the overmold portion and good bonding of the overmold portion onto the substrate portion can be at least maintained.

Embodiments of a vehicle interior system and methods for forming the same are disclosed. A glass substrate is bent to a curved shape within a mold cavity, and a liquid polymer material is delivered to the mold and is in contact with the curved glass substrate. The liquid polymer is solidified to form a polymer frame that engages the bent glass substrate, and the engagement between the frame and the glass substrate holds the glass substrate in the bent shape. The temperature of the glass substrate during the bending process and formation of the frame are maintained below the glass transition temperature of the glass substrate.

Embodiments herein relate to multilayer films for food packaging including migratory active substances.
