Less space, less weight, more convenience.
Maintaining an adequate supply of DuPont™ Tyvek® is simple.
Rolls of Tyvek® should be stored vertically on their ends and in their shipping wrappers. Horizontal storage can cause flat spots that, in turn, can lead to processing difficulties. Rolls should be handled carefully with a dolly, stevedore truck or hand truck. Avoid drops or bumps that could cause deformation. Never move a roll by turning or rocking it on its end. Clamp trucks can crush cores and distort Tyvek®. Clamp pressure should be set to a maximum of 1,800-2,000 psi (12,400- 13,800 Pa) gauge and core plugs should always be in place when handling rolls.
Because of the slippery nature of Tyvek®, care must be taken when moving loaded fork trucks over bumpy floors, up and down inclines and around sharp turns. When trucking material over any distance in sheeted form, the use of preformed corner angles, corner edge guides and flat pallet tops are recommended. A light tension on vertical and horizontal strapping can also prevent shifting and edge damage to the sheets.
If rolls or sheets are to be stored for several months, they should be wrapped in Tyvek® or polyethylene film for protection. Unbleached kraft paper should not be used because it may cause a yellowing of the edges and top sheets. Storage in areas where engine or space heater exhaust gases concentrate may also cause yellowing. Short exposure to sunlight will usually cause this color to disappear. If Tyvek® is stored outdoors, it should be protected from direct exposure to sunlight because prolonged exposure to UV light will cause a deterioration of physical properties.
