Abstract
A dual-durometer integral synthetic resin hinge joins two relatively rigid synthetic resin sections. The hinge comprises a first ply of the same composition and hardness as the rigid panels and an overlying second ply of relatively softer synthetic resin material. The first ply of the hinge is scored to provide a fracture line adjacent the hinge axis.
