Why Polyester?

Polyester is known for its stability and durability. It does not chemically react with stored items, making it ideal for long-term preservation as well as excellent protection against dust, dirt, and physical damage. High tensile strength ensures that polyester sleeves and enclosures do not tear or stretch easily.

Polyester is the first choice for many museums and archives for their most precious documents and images - not only are the contents protected against nearly all forms of damage apart from light, but the clarity means they can stay protected whilst being viewed as there is no need to remove the items from their polyester sleeves.
