 The Development of Blister Machine


Blister packing machines from how to make it to become a commercial product. In the mid-20th century, the strong demand for advanced packaging led industry experts and R&D researchers to start considering a product that could really increase efficiency in the pharmaceutical industry. The early models were rudimentary, focusing primarily on basic functionality. As the technology and materials development, the blister machine has made a big progress in the design.


The development of blister machines has been driven by the pharmaceutical industry's stringent requirements. Innovations such as thermoforming and cold forming have enhanced the machines' capabilities, allowing for more precise and reliable packaging. Today, modern blister packing machines are equipped with sophisticated features like automated feeding systems, high-speed production capabilities, and advanced quality control mechanisms.


 The Application of Blister Packing Machine


Blister packing machines are widely used across various industries, but their primary application is in the pharmaceutical sector. They are designed to protect tablets, capsules from malicious or nature environmental damage.


Blister Packed Tablet and Capsule


In addition to pharmaceuticals, blister packing machines are also used to pack the jam, cosmetic, perfume, vape, medical scalpel, ball pill, inject vaccine, etc. The electronics industry utilizes these machines to package small components, while the consumer goods sector uses them for items like batteries, razors, and stationery.



The Working Principle of Blister Machine


The working principle of a blister packing machine involves several key steps. These machines can be categorized into two main types: heat forming for pvc-alu blister packing, and room temperature forming for alu-alu blister packing.


 Heat Blister Packing Machines


1. Material Feeding: A roll of plastic film or sheet is fed into the machine.

2. Heating: The plastic film is heated to a pliable state.

3. Forming: The heated film is then molded into cavities using a forming die with a compressed air blowing.

4. Product Loading: Products are placed into the formed cavities either manually or automatically.

5. Sealing: A lidding material (usually aluminum foil) is placed over the cavities and sealed using heat and pressure.

7. Indentation: The indentation is optional for the blister machine, this process is to press the bath number and production date on the plate.

6. Cutting: The blister packs are cut into individual units.


 Room Temperature Forming Blister Packing Machines


1. Material Feeding: A roll of aluminum-based laminate is fed into the machine.

2. Forming: The laminate is pressed into cavities without heating.

3. Product Loading: Products are placed into the formed cavities.

4. Sealing: A lidding material (usually plastic film) is placed over the cavities and sealed using heat and pressure.

5. Cutting: The blister packs are cut into individual units.


The Type of Blister Packing Machine


Blister packing machines can be classified into several types based on their design and functionality:


1. Rotary Blister Packing Machines: These machines use a rotating drum for forming and sealing the blisters. They are suitable for high-speed production.

2. Flat-Plate Blister Packing Machines: These machines use flat plates for forming and sealing. They offer more precise control and are ideal for packaging delicate products.

3. Roller-Type Blister Packing Machines: These machines use rollers for forming and sealing and are known for their high efficiency and speed.

4. Continuous Motion Blister Packing Machines: These machines are designed for continuous operation and are used for large-scale production.


The Blister Packing Machine Market in China


China is a major player in the global blister packing machine market. The country's manufacturing capabilities, coupled with advancements in technology, have positioned it as a leading supplier of these machines. However, the advanced blister machine is produced in USA and Europe. But China blister machine is highly competitive in the price and it’s sophisticated design. The market in China is in keen competition, which make the manufacturer focus more on the innovation and the quality. Chinese blister packing machines are known for the high performance cost ratio, making them an attractive option for pharmaceutical industry decision maker at the same time, no need to worry about the packaging quality.
