The blister forming process involves shaping the film into individual compartments using a specialized mold. The process starts with a roll of plastic film, often made from PVC, PET, or other materials. The film is fed into the blister machine, where it is heated until it becomes soft and pliable. The heated film is then pressed into a mold, which forms it into the shape of the individual compartments.
Once the film is formed into blisters, the next step is filling the compartments. This is typically done through a machine-controlled process that accurately places the medication into each blister. Depending on the type of medication, the filling can be done manually or automatically. After the compartments are filled, the machine moves to the next stage: sealing.
Sealing is a critical part of the blister pack manufacturing process. The blister machine uses a heat sealing method to bond the plastic film with a backing material, usually aluminum foil. Heat is applied to both the plastic and the backing material, causing them to fuse together and form a tight seal. This process ensures that the medication remains secure and protected from external elements like moisture and air.
Once the blister pack is sealed, the final step is cutting the packs into individual units. The sealed strips of blister packs are cut into smaller segments, each containing one or more doses of medication. This cutting process is precise, ensuring that each blister pack is properly sized and ready for distribution.
