1. A protected hardenable dental article comprising:
a hardenable dental article comprising a base and at least one outer surface extending from the base, wherein at least the base and the at least one outer surface of the hardenable dental article comprise a hardenable dental material; and a multi-layer polymeric film conformable release liner in contact with at least a portion of the at least one outer surface; wherein the multi-layer polymeric film is removable from the hardenable dental article and comprises at least two dissimilar polymers in separate layers such that the multi-layer polymeric film comprises at least three layers, including a first outer layer, a second core layer, a third outer layer; and the multi-layer polymeric film exerts a tensile load of not more than 30 newtons at an extension from 325 to 600 percent and has an elastic recovery of not more than 85 percent at a tensile load of less than 0.044 newtons after recovery from an extension of 600 percent. |
