To make a deep-drawn pocket at the blister packaging (which comprises the merchandise ), plastic materials are used. Mostly used plastic forming movies are polypropylene (PP), PVDC (polyvinylidene chloride), polyvinyl chloride (PVC1), and PVC and ACLAR (CTFE). They may look similar in appearance but vary greatly in their attributes.
They're used together with aluminum foil (known as lidding material) to airtight the forming film instance. To finish the incorporated blister packaging both forming movies and lidding material must complement each other.
Lidding substances are used for sealing when pills or capsules are fed into the forming film instances. They consist of support material like aluminum, using a printed primer on the same side, and sealing agent on the other. The side of the sealing agent is faced with the goods and forming a film, then it's sealed with a heating technique.
