Material formation
Here, a plastic film is unwound from the reel and guided the pre-heating on the blister line. This process softens the plastic making it pliable. The warm plastic is pressurized followed by cooling to make it rigid and maintain the shape. The next process is cold forming whereby aluminum is pressed and elongated to create a barrier for water and oxygen allowing an extended product expiry date.

Product loading 
Product loading entails batch size, product types, and characteristics, blister design and type of barrier to be applied.

Product Sealing 
At this stage, the product is sealed using temperature and pressure to protect the product.
