Tyvek® is the name given to a family of tough, durable sheet products manufactured by Dupont from pure 100% high density polyethylene (HDPE).
Tyvek® is formed first by spinning continuous strands of very fine interconnected fibres, and then bonding them together with heat and pressure. The result is a bright white, spunbonded sheet which combines a good printing surface with high opacity, chemical resistance, and toughness.
Tyvek® has no grain direction, is corona treated on both sides to improve ink adhesion and is coated with an antistatic agent to facilitate converting.
In the conservation sector Tyvek® is used extensively by museum and collection management professionals as a protective non-abrasive, spore resistant and dust proof barrier for textile s, furnishings, paintings and a wide variety of artefacts and object d'art. Tyvek® is used to support large items undergoing conservation treatments, to make protective enclosures and in the creation of labels to attach to artefacts in storage.
In the industrial sector Tyvek® is used in the building and construction industries as a lining material, and in the packaging and printing industries as a substrate to create particularly strong and resilient packaging and promotional accessories.
