Tyvek/Foil Peelable Structure
A peelable structure that has all the benefits of Tyvek and all the benefits of foil in one package is offered. It is intended for products that need the ultimate in protection from gases, moisture, and light and also need the superior durability and strength properties of Tyvek, while not losing the dimensional stability and flatness of Tyvek structures and not losing the dead fold abilities of foil. A34T is a meeting of the materials. Tyvek, traditionally only used in breathable structures, has many structural benefits that made the perfect partner to marry to aluminum foil.
