Dear Sara:
Please check the following websit: <http://

This websit provides very practical, and useful information about supplies
and materials for museum collections.
Coroplast composed of 90% food-grade polypropylene and 10% polyrthylene,
looking like a plastic version of corrugated cardboard. The uncoloured
translucent is marketed as "archival", and said to be free of colouring
agents, and anti-static and ultraviolet inhibitors. But it may degrade
when exposed to sunlight. Coroplast is said to offer 15-20 years
protection for non-ferrous mentals.
It is very easy to make any shape of storage box with coloplast, boxes can
be constructed by screwing, rivetting, stitching, trying with cotton tape,
glueing with hot-melt Japanese rice glue, or using staple or plastic
fasteners. Chemically, they have no difference between per-made, custom
made box , or board itself.
Correx is very similar to Coroplast, they have different trade name
and each produced different densities, and thicknesses to suit their buyers.
Best Wish,
