Use a piano hinge for strength so you can attach the trunk top to the top of the trunk for closing.

Vast arrays of different types of hinges exist. Each type of hinge is designed for a distinct purpose that will take into account the hinges: style, size, strength, and aesthetics. One big difference between piano hinges and other hinge types is the fact that piano hinges will run the full length of the surface for proper fit.

Piano hinges are easy to install, are very affordable, and are extremely durable. This makes them perfect candidates for applications that are subjected to extensive use (or abuse) and intense wear and tear. When strength is a prerequisite, piano hinges are preferred.
