What is a blister pack? Everything you need to know

When you buy products such as batteries, medicines, or electronics, you often encounter packaging that is transparent. You can see the product, but it is securely packaged. This type of packaging is called blister packaging. It is designed to protect products, improve presentation, and increase ease of use. But what exactly is a blister pack? In this blog, we will tell you everything you need to know, from the different types to the characteristics and advantages of this type of packaging. Read on for all the information. 

What is blister packaging?

So, what is blister packaging? It is a type of packaging in which a product is enclosed in a preformed, transparent plastic part. This part is also known as a ‘blister’. The blister is usually attached to a cardboard or aluminum backing. Its purpose is to make the product visible to the consumer while protecting it from external influences such as moisture, dust, or tampering. Blister packaging is widely used in retail because of its price-quality ratio and ability to present products in an attractive way. 

What is a blister pack?

The term ‘blister’ refers to the transparent, preformed plastic part of the blister packaging. This plastic part is made by heating a plastic sheet and molding it into the desired shape. The blister securely encloses the product and ensures that it remains clearly visible to the consumer.

Blisters are manufactured from different materials, depending on the application. For example, they can be made from PVC (polyvinyl chloride), which is widely used because of its transparency and good price-quality ratio. Another option is PET (polyethylene terephthalate), a type of mono plastic that is recyclable and very clear. This ensures extra good visibility of the product.

Characteristics and benefits of blister packaging

You may be wondering, what is characteristic of a blister pack? Well, blister packs have several characteristics that make it suitable for various applications:

·         Transparency: the transparent blister allows the product to be seen immediately, which makes it more attractive.

·         Protection: they offer protection against moisture, dust, and tampering. This preserves the shelf life and integrity of the product.

·         Ease of use: many blister packs are designed to be easy to open, for example by pushing the product out.

·         Presentation: the combination of blister and cardboard backing provides space for branding, instructions, and other product information.

·         Theft prevention: the sturdy, sealed packaging makes it more difficult to remove products unseen, which can reduce theft in stores. Protective packaging solutions should therefore not be underestimated.

What is a blister pack and what is not?

Sometimes it can be confusing to know whether something is blister packaging or not. In short, packaging is not blister packaging if it does not consist of a preformed, transparent plastic shell that makes the product visible and protects it. Examples include a cardboard box that is completely closed, or flexible plastic or foil packaging that is completely wrapped around the product. 

These are a few types that do fall under blister packaging:

Standard blister packaging

This consists of a preformed plastic blister attached to a cardboard backing. The product is visible and the backing provides space for information.

Clamshell blister packaging

A clamshell consists of two identical plastic parts that close around the product like a shell. They are often used for heavier or valuable products because of their extra strength.

Face seal blister packaging

In this variant, the blister is only attached to the edges on the back, making the product fully visible. This method is attractive because of its good price-quality ratio and is suitable for lightweight products.

Trapped blister packaging

Here, the plastic blister is placed between two cardboard cards. This provides extra strength and looks professional.

Cold seal blister packaging

This packaging is sealed without heat, using pressure alone. This is energy efficient and suitable for products that are sensitive to heat.

So, now you have the answer to the question “what is a blister pack.” In any case, it is a versatile and effective packaging solution that offers protection, visibility, and ease of use. By choosing the right blister packaging, you can optimize the appeal and functionality of your product packaging!
