A machine (M) for producing blister packs ( 10 ) includes unrolling means ( 3,7,21 ) for unrolling a band of heat-formable material from a bobbin ( 2 ) and for feeding the band ( 1 ) along a predetermined path (P) extending through subsequent stations ( 5,6,30,8,9,13 ), in which the band ( 1 ) is processed. The above-mentioned stations include a heating station ( 5 ), where the band ( 1 ) of heat-formable material is heated, a forming station ( 6 ), where a plurality of blisters ( 20 ) are formed on the band ( 1 ), a filling station ( 8 ), where the blisters ( 20 ) are filled with products, a sealing station ( 9 ), where the blister band ( 1 a) is closed with a sealing band ( 11 ), and a cutting station ( 13 ), where the closed blister band ( 1 ac) is cut into blister packs ( 10 ). A further heating station ( 30 ) is provided for heating the blister band ( 1 a) along the path (P) upstream of the filling station ( 8 ), so as to heat the band ( 1 a) to cause a thermal stabilization treatment of the blister band ( 1 a).
