Hinge feature - can anybody help?

I need to design a hinge feature into a plastic part. The part will
be moulded flat and the hinge will be a thin section of plastic
between the two halves - the sort of thing you find on bottle tops and
enclosures with lids.

does anyone know of a free internet guide that discusses recommended
cross sections (for strength and reliability), I've seen similar
guides for clip features published by toolmakers and plastics material
distributors.

Thanks in advance

Rich.
