Blister packaging refers to a packaging method in which the product is sealed between a blister formed of a transparent plastic sheet and a substrate (made of cardboard, plastic film or sheet, aluminum foil, or composite materials thereof).
Pharmaceutical blister packaging machines play a vital role in the pharmaceutical industry, ensuring the safe and efficient packaging of pharmaceuticals. This blog post aims to provide pharmaceutical industry professionals with solutions to common problems with blister packaging machines.

What is a blister packaging machine?
A blister packaging machine is a piece of equipment used in the packaging industry to create blister packs, which are a type of pre-formed plastic packaging used to enclose items for retail display and protection.
The machine typically consists of a forming station, where plastic sheets are heated and shaped into individual cavities, and a sealing station, where the product is placed into the formed cavities and the plastic is sealed with a backing material such as foil or paperboard.
The machine operates automatically and can handle high volumes of products, providing efficient and consistent packaging.
Components of Blister Packaging Machine
The main part of the blister packaging machine is the material forming structure. The material is obtained from the feed frame, heated to the appropriate temperature, and then formed into the frame. This 18-part structure can be customized depending on material type and packaging requirements.
In the pharmaceutical sector, blister packaging machines serve a variety of purposes. Packaging of pills, capsules or injections can be done using these devices. They are capable of handling a wide range of substances, including liquids, powders and solids.
In addition, the blister packaging machine will be able to pre-print materials for the lid of each package. It will also have a printed positioning mechanism to help regulate where the sealing material sits within the blister cavity. It can also emboss sealed packaging if the manufacturer must do so.

What Are the Types of Blister Packaging Machines?
Divided according to machine structure:
Roll-type blister packaging machine
The roller-type blister packaging machine functions by heating and softening the forming film, which is then shaped into blisters using a vacuum on a roller die.
The materials are filled into the blisters, and sealed with a heat sealing roller under precise temperature and pressure using an adhesive-coated covering film. It then imprints batch numbers, presses break lines and punches out the final product into designated sizes.
Due to the use of roll forming, sealing and feeding, the blister tape will bend on the roller surface during operation, so it is not suitable for forming large, deep and complex blister packaging. The size of items should also be smaller.
Flat blister packaging machine
The flat-plate blister packaging machine operates by heating the film to soften it, then using compressed air to form the blister. The product is placed into the blister, which is then sealed with a covering film at the right temperature and pressure. Next, the machine prints batch numbers and creates perforation lines before the completed product board is cut to size.
This model has a large filling space and can arrange multiple filling machines at the same time, making it easier to package multiple drugs in one tray, expanding the packaging range and improving packaging efficiency.
The operation methods of pharmacy blister packaging machines are mainly divided into semi-automatic operation and fully automatic operation.
Semi-automatic blister packaging
Rolls or individual plastic sheets are fed into the semi-automatic blister packaging machine, which operates continuously or intermittently. The number of forming molds depends on the size and output of the product, and is generally multi-row.
After molding and cooling, the product is manually packed into the blister. The printed roll or individually shaped substrate is placed on the blister and the trimmed edges are heat-sealed to obtain the complete packaging component.
Fully automatic blister packaging
The fully automated blister packaging process involves using specialized equipment to automatically form plastic blisters and seal them to preprinted cards or backings.
The process is streamlined and efficient, enabling high production speeds and consistent results. Packaging can be customized to the specific dimensions and requirements of the product, ensuring a perfect fit and maximum protection.
One of the main advantages of fully automated blister packaging is the ability to provide tamper-proof packaging. The sealed blister protects the product from damage and contamination, while also allowing easy detection of package tampering. This gives both manufacturers and consumers peace of mind as it ensures the integrity of the product.
In addition to functionality and aesthetics, fully automated blister packagingmachine can save costs and improve operational efficiency. Automated processes reduce labor and handling costs while also minimizing the risk of human error. High production speeds enable manufacturers to meet strict production schedules and complete large orders in a timely manner.
What Are the Advantages and Disadvantages of Blister Packaging?
Advantage
Visual impact: Blister-packed products are usually more eye-catching than box-packaged products, making it easy to catch consumers’ eyes.
Protection: Blister packaging protects products from damage and keeps them clean. They also show when a package has been tampered with (unlike a box, which someone can open and close without showing it).
Lightweight: Blister and clam packs are extremely lightweight, thus reducing shipping costs.
Easily recyclable: Clam packaging is particularly easy to recycle because it is made from pure plastic.
To help follow these medication habits: Packaging can be marked so that each small pocket containing tablets or pills is numbered or listed by day. Unlike bottles, it also helps people monitor how many pills they’ve taken.
Shortcoming
Often more costly than other packaging methods
How to Clean a Blister Packaging Machine?
Cleaning your blister packaging machine is an important step in maintaining its efficiency and hygiene.
Here are some steps for cleaning your blister packaging machine:

1. Turn off the machine and unplug the power plug to ensure safety during cleaning.
2. Remove any remaining blister sheets, packaging materials or product from the machine. Dispose of them properly.
3. Use a soft brush or vacuum cleaner to remove loose particles, dust and debris from the machine. Pay attention to areas such as feed conveyors, molds, and sealing stations.
4. Prepare a non-abrasive cleaning solution by diluting a mild detergent or specialized machine cleaner in water according to the manufacturer’s instructions.
5. Dampen a clean cloth or sponge with cleaning solution and gently wipe all accessible surfaces of the machine. Be careful with electrical components and sensitive areas. Clean up any residue or spills that may have accumulated.
6. Pay special attention to areas that come into direct contact with product or packaging materials, such as forming areas, heating elements, and sealing stations. Use a soft brush or special tool to reach hard-to-reach areas.
7. Allow the machine to air dry completely before reconnecting the power source and using it again.
8. Regularly inspect and clean your machine’s filters, vents, and ventilation system in accordance with the manufacturer’s instructions. This helps maintain proper air circulation and prevents overheating.
9. Finally, disinfect the machine in accordance with current hygiene guidelines and regulations. This step is critical to ensuring a clean and safe packaging prcess.
