Abstract:
A method of making an array of packaging blisters on substrates, comprising:a) providing a semi-rigid preformed plastic sheet containing packaging blisters; each blister being defined by a side wall and a transversely extending top wall integral therewith, and wherein the side walls of adjacent blisters on the sheet are separated by flanges;b) depositing adhesive onto a sheet of release material;c) positioning the semi-rigid preformed plastic sheet on the release material bearing the adhesive so as to bring the flanges of the blisters into contact with the adhesive and form a laminate therewith; andd) pressing and cutting the laminate at locations aligned with the flanges, wherein the pressure applied is sufficient to bring the adhesive into intimate holding contact with the flanges while severing the semi-rigid preformed plastic sheet along the flanges but not the release material; whereby the blisters are individually removable from the release sheet for use as packages on substrates.
