3. What Plastic Material is Used for Heat Seal Blister Packaging?

The plastic used for most heat seal blister packs is either PVC or PET.

This is because PVC and PET are known to be the most suitable for heat sealing processes.

Both materials also offer excellent clarity that enhances the visibility of products while on display.

4. How is Heat Seal Blister Pack made?

The heat seal blister packaging process is fairly simple. It can be done in segments or all at once. Regardless of how it is done, the process follows the same order as seen below.

The process begins with the input of raw materials. These include the plastic material, backing material, and the product itself.

If the backing material, i.e. paperboard is brought in as one large piece, it is cut into properly sized sections before manufacturing begins.

Next, the plastic material which is usually in the form of sheets or film is fed into the thermoforming machine.

The machine heats the plastic material under set temperatures to make it soft so that it can easily be formed.

Once malleable, the plastic moves to the next stage where it is fed into/onto molds that create one or more cavities to hold the product.

After thermoforming, the plastic undergoes a short cooling process after which it is now ready for the heat sealing process.

To seal; the product is placed in the plastic blister, and the backing is placed on top of (or around, depending on the package) the heat seal blister.

Next, the blister plastic is bonded onto the paperboard/card using heat and pressure.

Once sealed, the packaging process is complete, and the packaging is ready to be ejected.

Note that each step of the blister packaging process is unique and individually needed.

Also, each of the steps directly impacts the seal strength.

As such, everything must be done and monitored carefully.

Parameters such as temperature and pressure must also be controlled to ensure quality production.
