Abstract:
A method for producing stand-up blister packages, in which blister domes with blister edges are shaped from a film sheet of thermoplastic plastic, separated from the film sheet, transferred into circulating, cyclically-moved sealing pallets, filled with an item, and sealed with a carrier part through large-surface heating of the blister edges, said method including the following method steps:sealing one of the blister edges with the carrier part in a transverse-sealing station; cooling the one blister edge and the carrier part to form a stand-up blister package preform; linearly heating a transition region of the blister edge between the blister dome and the carrier part in a heating station to form a narrow, heated fold line; folding the carrier part, and the blister edge connected thereto, by 180Â° along this heated fold line; and sealing remaining blister edges with the carrier part to form a sealed stand-up blister package.
