<p>PROBLEM TO BE SOLVED: To provide a chemical packing body brittle and excellent in moistureproofness and heat resistance without using aluminum foil for cover material in a PTP packing form. SOLUTION: Cover material is a sheet formed by applying an adhesive as a sealing layer to a film with a petroleum resin added to an amorphous polyolefin resin, a film with the petroleum resin and inorganic material added to the amorphous polyolefin resin or a film with the petroleum resin and an organic resin added to amorphous polyolefin resin as base material, or laminating polyolefin resin films or polyolefin resin drawn films or jointly extruding a polyolefin resin and further laminating an outer layer on the opposite side to the sealing layer if necessary. This sheet is laminated on a sheet formed into a recessed shape to enclose solid chemical as bottom material, and a cover material part is broken by pressing a formed part to obtain a press through pack form.</p> |
