The blister packaging process typically involves several steps, including:
Design and layout: The first step is to design and layout the blister pack, including the size and shape of the blister cavities, the layout of the product within the cavities, and the overall design of the backing card or other packaging materials. This step can be done using specialized software, as mentioned before.
Material preparation: Next, the materials needed for the blister pack, such as plastic sheets, backing cards, and any additional features such as peelable seals or push-through tabs, are prepared.
Forming: The plastic sheet is then heated to a pliable state (in case of thermoforming) or high pressure is applied (in case of cold forming) and formed into the desired shape using a mold. The formed plastic is then cooled and cut to create individual blister cavities.
Filling: The formed blister cavities are then filled with the product, usually a tablet or capsule.
Sealing: The filled blister cavities are then sealed to the backing card to create the final blister pack. This can be done using heat or pressure, depending on the type of blister pack being created.
Quality control: After the blister packs are created, they are inspected for any defects or issues before being packaged and shipped.
Packaging and shipping: The blister packs are then packaged and shipped to their final destination.
