Mitsubishi Escal and Mitsubishi PTS are made to offer not only a
high oxygen barrier but also a high moisture barrier which is more
difficult to achieve in a transparent film. These products have a
ceramic coating which offers the highest moisture barrier of any
transparent plastic that we know of.

Combine this with the Mitsubishi RP System oxygen scavengers,
possibly type A which reduces moisture or type K which is moisture
neutral and should not alter the moisture content of the object and
you should have your transport method. Take care to protect the bag
by placing it in a box. For this purpose Conservation By Design have
produced a flat pack archival box with a transparent polyester
window in the lid. This allows viewing of the object within the
barrier bag whilst protecting the bag from puncture.

Our Window Boxes are available either in standard sizes or as tailor
made Smart Boxes. With regard to the question of light our tests
also show that anoxic storage also helps to prevent damage from UV
light. For long term display we are now able to offer oxygen free
showcases.
