Blister cards are a common unit dosage packaging for different pharmaceutical products. They are moist and airtight, and thereby often prolongs shelf life of the product.
A blister pack is produced using a form-fill-seal process. In this process, first the container is formed, then the pharmaceutical product is filled in the container, and finally it is sealed. The container is formed directly from a roll of plastic wrap or other material, including PVC, PVCD, aclar, or aluminum. This is done by thermoforming or cold forming depending on material used. For pharmaceutical products, foil or a combination of foil and paper is normally used to close and seal a blister card. The entire process takes place on the same blister line.
Blister foil and other sealing material
For push-through blister packs, foil is commonly used to close and seal it. Child-resistant blister cards are most often made of a mix of foil and paper. This makes it harder to push the product through the sealing. Moreover, blister cards can be made from cold formed aluminum-aluminum (alu-alu). Alu-alu is the only packaging that is 100% protecting against moist, air and light. Therefore, it typically applies to extra sensitive products. Moreover, blister foil helps to ensure the integrity of the product, as any breakage of the foil will be clearly visible.
Noack blister machines can process several different types of sealing material. This includes common types of thermoforming films, cold forming films and film for alu-alu blister cards.
