Overview
DUNMORE security films utilize DUN-GUARD™, a selective-release film that is available with surface or sub-surface destruct layers. The film separates depending on its construction to leave evidence of tampering, typically "void", however custom designs,such as a corporate logo, can be applied to any construction. The label facestock material is available in a variety of colors, including metallized finishes, and can be custom color matched for your specific application. A more covert security function is the use of UV / IR or taggants that require devices to authenticate.

SUB-SURFACE Destruct Film
The sub-surface destruct film incorporates either a metallized or a coated layer which, when applied to a substrate with a suitable pressure-sensitive adhesive, allows for immediate identification of tampering if any attempt is made to remove the label. When the label is removed from the substrate, either the metallized or the coated layer splits from the film leaving the imprinted "void" pattern showing undeniable evidence of tampering.

Surface Destruct Film
The surface destruct film is designed for use in conjunction with an overlaminate. If the overlaminate is removed, the imprintable surface of the label splits in a tamper-evident pattern.
