Abstract
Abstract A package for adhesive-surfaced sheet-like articles which may be delicate is formed by mounting the adhesive surface of the article onto a two-part release-surfaced carrier, one part of which supports the periphery of the article and the other part supporting the interior area of the article. With such a package, adhesive-surfaced sheet-like articles can be accurately placed onto an adherend without danger of contaminating the adhesive surface or allowing tearing, curling, or distortion of the article.
