Vacuum packing

From: David Kerr <d.kerr>
Date: Monday, June 7, 2004
I am experimenting with vacuum packing as a means of storing
newspapers and I would like to find out more about other peoples
experiences using vacuum packing technology as a means of storing
library material.  I know the benefits of anoxic packaging to
prevent chemical and biological reactions but there are a few areas
in which I'd like find out more on, including peoples experience or
thoughts on:

What barrier films should we be looking at for long term storage of
material and what shelf life do these barrier films have?

If newspapers are vacuum packed, making them a solid block, can they
be stored vertically or is there still a risk of distortion if
stored this way?

Should we put a buffer, such as acid free paper, between the item
being stored and the barrier film?

Should oxygen scavengers always be used?

Has anybody carried out a study to find out how much shelf space is
saved when vacuum packing as opposed to boxing material?

Any other tips be greatly appreciated.
