Ampak's industrial rotary blister card sealers are designed for reliability and performance. Blister card sealers heat seal formed plastic onto cards. The plastic forms are placed in a die, product is added into the plastic form and then a card is placed on top. The plastic pack is then heated and sealed to the card. Blister card sealers are used to display loose products like screws, candy, pens, batteries, small travel items and more while not locking the product to the card.
