    摘要： A blister-board article is provided that includes a substrate and a unique adhesive material layer that is above the substrate. The blister-board article is useful as a base for an information layer and a blister packaging material that is bonded to the unique adhesive material layer through the information layer. A blister-pack system is also disclosed in which an object is between a blister layer and the adhesive material layer. A process is also disclosed including the formation of a sizing layer upon the substrate. Optionally, a base coat layer is formed, either on a starch sizing layer or directly on the substrate.

    摘要： Disclosed are a composite gypsum board and a method of preparing composite gypsum board. The board contains set gypsum layers sandwiched between two cover sheets. The set gypsum layers are formed from at least stucco and water. The set gypsum layers include a board core and one or more skim coat layers. The set gypsum core makes up a substantial thickness (e.g., at least about 90%, at least about 92%, at least about 95%, or at least about 97%) of the total thickness of all the gypsum layers. A first skim coat layer is included on one side of the core, facing a first (face) cover sheet. A second skim coat layer is included on the other side of the core, facing a second (back) cover sheet. At least the second skim layer is formed from a slurry that contains starch. The stucco material generally includes a high salt impurity content, for example, when the stucco is calcined from certain sources of low-quality synthetic gypsum. For example, in some embodiments, the salts are chloride salts, e.g., sodium chloride (NaCl), potassium chloride (KCl), magnesium chloride (MgCl2), and/or calcium chloride (CaCl2).
