What is Blister Packing Machine Process of Operation?

Blister Packing Machine is an automated packaging machine widely used in pharmaceutical, food, electronics and consumer goods industries. Its main function is to encapsulate the product in a transparent blister made of plastic or aluminum foil to protect the product and provide a convenient form of packaging. It includes multiple process working locations, including material heating forming, multi-type feed filling (tablets/capsules/liquids/solids, etc.), heating sealing, indentation embossing, traction and blanking processes. Today, I mainly explain to you the operation and process of the flat type aluminum-plastic packaging machine.

Introduction of each station of flat type aluminum-plastic packaging machine:

1.Forming material; 2. Heat; 3. Molding; 4. Material filling; 5. Scrap inspection; 6. Heating seal; 7. Indentation; 8. Back aluminum film; 9. Traction; 10. Blanking

The following is the detailed operation process of the Blister Packing Machine:

Material preparation and loading: First, operators need to prepare packaging materials and products to be packaged. Packaging materials usually include plastic sheets (such as PVC, PET, or PVDC) and aluminum foil as a backplane. The plastic sheet is loaded into the machine's feed system, while the aluminum foil is installed on the corresponding unwinding device. The product to be packaged needs to be packed into a specially designed feeding system according to its shape and size.

2. Plastic sheet preheating: The heating station of the Blister Packing Machine will preheat the plastic sheet. This step is very important because it allows the plastic to reach the right temperature to soften it and make it more plastic for the subsequent molding process. The control of the preheating temperature needs to be precise because different types of plastic materials have different softening temperatures. The operator can adjust the temperature through the control panel to ensure optimal preheating.

3. Plastic sheet molding: the preheated plastic sheet will enter the molding station. Here, the machine uses pressure and compressed air technology to press the plastic sheets into the desired blister shape. The molding mold is customized according to the specific size and shape of the product, and a variety of different blister molding molds can be made according to the shape needs of different products. During the molding process, the easily softened plastic in the mold is blown by the compressed air system, ensuring that the plastic can fully fit the mold surface and form an accurate blister shape.

4. Product filling: The bubble cap will be moved to the material filling station after forming. In this stage, the Blister Packing Machine will accurately place the product into each blister cap through a precision robot or vibrating disk feeding system (some special materials can also be manually placed). To ensure the quality and efficiency of packaging, machines are often equipped with a visual inspection system to monitor the correct placement and integrity of the product. If any abnormality is detected, the system will issue an alert or automatically remove the unqualified product to prevent the unqualified product from reaching the hands of consumers.

5. Aluminum foil seal: After the product is filled, the blister cap will move to the heating seal station. Here, the aluminum foil material is placed precisely above the blister cap. The hot press device then applies pressure and heat to the entire surface, sealing the foil firmly on the blister. This process requires precise control of temperature, pressure and time to ensure a perfect seal, prevent air and moisture from entering the inside of the package, and keep the foil surface flat and beautiful after heat sealing.

6. Cooling: The sealed aluminum-plastic board needs to be cooled immediately. Cooling stations usually use cold air or cooling plates to quickly reduce the temperature of the package. This step can not only improve the strength of the package, but also prevent product deformation or damage caused by heat, affecting the integrity and beauty of the guarantee.

7. Coding and labeling: After the heat seal is completed, many Blister Packing machines are also equipped with coding or indentation systems. These systems can print important information such as batch numbers, production dates and expiration dates on packaging. This step is essential for both product traceability and marketing.

8. Cutting and forming: the finished product will enter the blanking station after heat sealing or coding. Here, the Blister Packing Machine cuts the tape into individual blister packs or multiple packs according to the preset size and shape. Cutting tools usually use precision stamping dies, which can be blanked and cut without damaging the contents of the package.

9. Quality check: At the last stage of the packaging process, the Blister Packing Machine usually also performs a final quality check. This may include weight testing, seal integrity checks, appearance checks, etc. Advanced machines may even be equipped with X-ray inspection systems to check the integrity and correctness of the products inside the package. Substandard packaging will be further automatically eliminated, ensuring that only high-quality products make it to the next step.

10. Collection and packaging: Qualified finished products are eventually collected into the discharge system. Depending on the needs, these packages may go directly to the connected carton packaging machine for secondary packaging, or be manually collected for subsequent processing.

The entire Blister Packing Machine operation process is highly automated, but still requires supervision and adjustment by skilled operators. Operators need to regularly check the various parts of the machine to ensure that they are working properly and adjust the machine parameters according to the needs of different products.

In addition, the Blister Packing Machine also has the following important functions and features:

1. High efficiency production: modern Blister Packing Machine can be packed at a very fast speed, and high-speed roller plate aluminum plastic machine can even reach the production speed of hundreds of thousands of packages per minute.

2. Flexibility: By changing the mold and adjusting the parameters, the same machine can be used to pack a variety of products of different sizes and shapes.

3. Precise control: The advanced control system allows the operator to precisely adjust the parameters of each workstation, such as temperature, pressure and time, to suit the needs of different materials and products.

4. Safety: Blister Packing Machine is usually equipped with multiple safety devices, such as emergency stop button, safety door interlock, etc., to protect the safety of the operator.

5. Cleanliness: Especially in the pharmaceutical industry, Blister Packing Machine design needs to meet strict cleaning standards, easy to clean and maintain, to ensure the hygiene of the production environment.

6. Data recording and analysis: Many modern Blister Packing machines are equipped with data recording systems, which can monitor and record production parameters in real time, contributing to quality control and production optimization.

7. Remote Monitoring and maintenance: Some high-end models even support remote monitoring and diagnostic functions, allowing the manufacturer or maintenance personnel to remotely access the machine for troubleshooting and software updates.

In short, the Blister Packing Machine is a complex and sophisticated packaging equipment, which through a series of carefully designed steps, the product is safely and hygienically packaged in aluminum plastic blister packaging. With the continuous advancement of technology, the efficiency, accuracy and functionality of Blister Packing Machine are constantly improving, providing high-quality and efficient packaging solutions for various industries.
