Blister Packaging Process Guide

When you are sick and take medicine in daily life, have you ever carefully observed the package of tablets/capsules in your hand? That layer of protection of the outer packaging of drugs is the use of aluminum blister machine for packaging. This article will take you in-depth understanding of this indispensable packaging equipment in the pharmaceutical industry.

The blister packaging machine is one of the core equipment in the pharmaceutical industry. It can accurately encapsulate medicines in a blister formed by plastic and aluminum foil, which not only protects the medicines from external contamination, but also extends the shelf life of the medicines. This type of packaging is suitable for all kinds of solid preparations, such as capsules, tablets, and even certain liquid medicines.

To understand the workflow of blister packaging machine, you need to know its main components first:

1. Feeding system: responsible for accurately conveying the medicine to the packing position.

2. forming station: heating and molding the plastic sheet to form the container for the medicine.

3. Filling station: puts the medicine into the plastic container precisely.

4. sealing station: seals the plastic containers with medicines with aluminum foil.

5. Punching station: cuts continuous packages into individual blisters.

6. control system: coordinates the actions of each workstation to ensure that the whole process is precise and error-free.

The core workflow of an blister packaging machine consists of four main steps: forming, filling, sealing and cutting. This seemingly simple process actually involves complex technology and precise control.

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

Now, let's dive into the detailed process of blister packaging:

Step 1: Plastic Molding

The packaging process begins with the plastic sheet. You'll see rolls of PVC or PTP plastic being fed into the machine. A heating unit will heat the plastic to the softening point. The heated plastic is then fed to the forming mold. Here, through vacuum suction or pressure molding, the plastic is formed into rows and rows of small grooves, which are the “chambers” for the medicines.

Step 2: Filling of the medicine

The molded plastic containers are moved to the filling station. Here you'll see a sophisticated feeding system that precisely places the medication into each of the grooves. Both rounded capsules and flat tablets are carefully placed in them. For liquid medications, a special filling system is used to ensure accurate dosing.

Step 3: Foil sealing

The plastic containers with medicines continue on to the sealing station. Here, a roll of aluminum foil is placed over the plastic container. By means of a hot or cold pressing technique, the aluminum foil is tightly fitted to the plastic container to form a seal. This step is crucial as it protects the medicine from air, light and moisture, extending its shelf life.

Step 4: Punching and molding

The final step is to cut the continuous package into individual blister sheets. The punch-cutting mold will precisely cut the package into a predetermined shape and size. You will see the complete blister packs output from the end of the machine with the pharmaceuticals neatly arranged inside.

blister packaging machine has a wide range of applications in the pharmaceutical industry:

1. blister packaging for tablets: such as common antipyretic, cold medicine and so on.

2. capsule aluminum blister packaging: all kinds of capsule drugs are suitable for this kind of packaging.

3. liquid aluminum blister packaging: some liquid drugs, perfume, personal care, cosmetics and other products can also be packaged in special aluminum blisters.

The use of aluminum blister packaging machine has a number of advantages:

1. Hygiene and safety: each medicine is sealed independently to avoid cross contamination.

2. Precise dosage: Each blister contains a fixed amount of medicine, which makes it easy for patients to take the medicine correctly.

3. Strong protection: Aluminum foil sealing can effectively isolate air, light and moisture.

4. Portable: small and lightweight, easy to put into pocket or medicine bag.

You now understand the workflow of the aluminum blister packaging machine. From plastic molding to final cutting, each step is carefully designed to ensure the quality and safety of medicines. This type of packaging not only protects the medicine, but is also convenient for patients, making it an important technology for the modern pharmaceutical industry.

I hope this article has helped you understand how aluminum blister packaging machines work. If you work in the pharmaceutical industry or are interested in pharmaceutical packaging, explore this technology further, it is changing the way we use medicines.
