UniCover Flex - Clear Acetate Binding Covers

The UniCover Flex by Unibind is a flexible thermal binding cover made from acetate and a steel u-shaped channel binding spine. One side has a crystal clear finish and the other has a frosted matte finish. This gives you two presentation options of either a fully transparent or semi-transparent front cover. The first page of your presentation will personalize the cover. You can even request your Crystal Flex covers to include optional foil-stamping as well as foil-printing to add your logo, name or other artwork to the cover.

UniCover Flex - Colors

UniFlex covers are available with the following spine colors: Aluminum, Azur, Black, Bordo, Dark Blue, Dark Green, Quartz and White. Choose a color that best matches your corporate colors or brightly stands out from the rest. Aluminum, Azure, and Quartz colors have a unique metallic finish, where Black, Bordo, Dark Blue/Green, and white have a more traditional finish.
