Blister packaging consist of two elements, the printed and coated blister card and the plastic blister. In a sealing process, the blister card and the blister are combined with each other by pressure and heat. The coating film and the blister soften, melt into each other and form a compound.
An alternative is blistering by means of ultrasonic sound. In the blister process, the coating acts as an agent between the blister card and the plastic blister. To ensure that this sensitive process works, ACTEGA Terra has developed highly specialised blister coatings with excellent sealing characteristics that proved to be leading in the market. As in the sealing process the hot tool comes into contact with the rear side of the printed and coated blister card, we recommend heat resistant coatings for the rear side.
