Which type of blister packaging machine is suitable for your needs?


As a common pharmaceutical packaging, blister packaging has been active at the forefront of the pharmaceutical packaging industry since its birth. Blister packaging was originally designed to package tablets and capsules to replace high-cost glass and plastic bottle packaging lines. Facts have proved that blister packaging is suitable for transporting and storing medicines due to its good airtightness. Even today, the demand for blister packaging is still rising.


Pharmaceutical manufacturers usually choose to purchase blister packaging machines to provide blisters for their products. The blister packaging machines currently on the market are divided into three types: roller type, plate type, and roller-plate type. The plate and roller-plate type blister packaging machines are the most common among them. Diverse types of blister packaging machines have their advantages and disadvantages. We will introduce their characteristics in detail to help you choose the most suitable machine for your products.


1.The roller blister machine uses cylindrical roller molds in the forming and heat-sealing process, and the heat-sealing is completed through the meshing movement of the heat-sealing roller and the anilox roller. It has low power consumption, a simple structure, and effortless operation, but it also has the disadvantages of a small molding area and slow production speed. In addition, due to its forming method, the roller blister machine is easy to cause uneven thickness of the blister wall, which is not suitable for producing blisters with deep blister holes.


2.The plate blister machine uses flat molds in the forming and heat-sealing process, and these molds are moved up and down in the vertical direction to complete the heat-sealing. The plate blister machine has an excellent forming area and forming depth, which enables it to produce blisters with large sizes and complex shapes. However, the intermittent conveying method limits the plate blister machine’s production speed, and its punching frequency is low.

3.The roller-plate blister machine combines the characteristics of the above two machines, it uses plate molds in the forming stage and roller molds in the heat-sealing stage. The roller-plate blister machine has excellent production speed, and its production continuity is significantly better than the other two machines. The heat-sealing method of linear contact makes the packaged medicine less affected by temperature and pressure, and the utilization rate of the packaging material of the roller-plate blister machine is also higher. The pursuit of higher production capacity makes the roller-plate blister machine insufficient in the variety of blisters it produces, it is more suitable for single-variety packaging or long-term mass packaging production.

According to the characteristics of the above three blister packaging machines, we believe that pharmaceutical manufacturers should consider product characteristics, purchase costs, and production capacity requirements when selecting blister packaging machines. Hoping Machinery has the series of DPH roller-plate blister machines and DPP plate blister machines. While consolidating the technology of the plate blister machine, we continue to pursue technological innovation and breakthroughs in the roller-type blister machine. You are welcome to browse all kinds of machines through our official website, we believe you can find the best choice among our products.
