The advantages of blister packaging

Even though they can be quite hard to open at times, blister packages are incredibly useful. The pharmaceutical industry, for instance, would be nowhere without blister packaging to contain and keep sterile all sorts of pills. So what other benefits lie beneath the hard to open surface of these clamshell packages?

Even today, when eco-friendly packaging is at the top of every brand’s list, plastic packaging still dominates the industry. It comes in all shapes and sizes and is used throughout all sorts of industries, from medical to retail, food and electronics. Blister packaging is especially popular for its ability to safely seal a product inside a container, while at the same time also revealing a large part of it to consumers.

Blister packaging: not the prettiest of designs

The technique used here is thermoforming, a manufacturing process where a plastic sheet is heated to a pliable forming temperature, formed to a specific shape in a mold. The plastic sheet is attached to a piece of cardboard displaying brand and product information. It might not be the most beautiful packaging technique from a designer’s point of view but it sure is effective!

Blister packaging for toys, pills, cosmetics, …

Blister packaging is most commonly used in the medical and pharmaceutical industries, sealing and keeping sterile pills and other drugstore related items. Yet other products benefit from blister packaging as well. What about that Barbie doll your daughter is always nagging for whenever you come across a toy store, allowing her to grab (and eventually drop!) the item from the shelf without damaging it? Other items include cosmetics and batteries, products that specifically need to remain hygienic during transportation to and from retailers.

Blister packaging is cheap

For all their convenience blister packages are relatively cheap to produce, slightly lower anyway than other plastic packaging techniques. During production many packs can be made at the same time that can each hold different items without having to alter too many variables. Imagine having to initiate a whole new packaging process for every pill that slightly differs in size and shape. It would make the manufacturing process almost unpayable.
