Leakproof Box 2
From DT Online
Beacause of the way the corners on this package are folded, it has the ability to hold liquids and fine powders. This package offers greater rigidity than leakproof box 1 because of its double thickness walls.
If the contents of package are to be wet, then an appropriate material must be used for the box, e.g. waxed card, foil, plastic etc.
