In solid wood maybe but I don't think you'd get a clean, tight fit in
chipboard. How about dampening the biscuits with water (so they swell)
then using polyurethane glue - that needs moisture to cure anyway.

No need. Fit will be good in chip, and just welly in PVA, slam in the
biscuits and wipe off the squidge with a wet sponge.


The melamine wont take the glue but that's why you have biscuits right?

Yes and no.

Biscuits are mainly an alignment device. If the bond on the edges of
the material is poor, then relying just on the biscuits for mechanical
strength is likely to lead to disappointment. If the box is small
then probably OK, but not anything of substantial size.
