Blister packaging is internationally known as blister pack

What is blistering?

Blistering is a technological process that involves packing products, usually small ones, in a specific type of packaging called blister (Ang. blister pack). This is one of the most popular methods of unit packaging, i.e. portioning and securing individual items of goods.

The blister packaging itself consists of two main parts:

Molded cavity: A transparent, rigid plastic “pocket” (e.g. PVC, PET) that is precisely fitted to the shape of the product.
Closing layers: A support usually made of cardboard, aluminum foil or other material, which is welded to the cavity, enclosing the product inside.

In everyday language, "blistering" simply means putting something in blisters.

Blister packaging - "blister pack"

What is blister packaging?

Blister packaging (internationally known as blister pack) is a popular type of packaging consisting of two main elements: a molded, transparent plastic cavity (known as a "blister") and a backing to which it is attached. The blister is precisely tailored to the shape of the product it is intended to protect.

This type of packaging is widely used in various industries, most often in pharmaceuticals (tablet and capsule drugs), electronics (batteries, memory cards), and also in the retail sale of small consumer goods (toys, cosmetics, office supplies). The transparency of the plastic allows for excellent product visibility, while the backing provides a surface for placing information, graphics and brand logos.

The main components of a blister pack are:

Molded blister: Typically made of plastics such as PVC (polyvinyl chloride), PET (polyethylene terephthalate) or PVDC (polyvinylidene chloride).
Base (cover): It can be made of cardboard, aluminum foil or other type of plastic.

Types of blister packaging

There are several variants of blister packaging, each adapted to different products and applications. In industry terminology, English names are often used, so it is worth knowing them:

Face Seal Blister: The most common type, in which a plastic blister is heat sealed to a cardboard liner. This is an economical solution for a wide range of consumer products.
Full-Face Seal Blister: Similar to the above, but the blister covers the entire front surface of the carton for greater rigidity and a more aesthetic appearance.
Clamshell: This is more extensive blister pack, consisting of two parts connected by a hinge that close the product inside. They can be closed with a snap or welded on the edges, which ensures a high level of security.
Trapped Blister: In this design, the blister is “trapped” between two layers of cardboard that are glued together. This provides greater security than a standard blister and offers more space for graphics.
Slide Blister: It has bent edges that wrap around the carton, allowing it to be pushed in and out. This is a reusable packaging option.
Pharmaceutical blisters: Specifically designed for medications, usually with an aluminum foil backing that can be pierced (“push-through”) to remove a single dose. They are crucial to maintaining the sterility and integrity of the medication.

Production process

Creating the packaging that is blister pack, is a multi-stage process:

Blister formation: The process begins with the creation of a plastic cavity. This is usually done by thermoforming, where a sheet of plastic is heated to a plastic temperature and then formed into a specific shape using a die and vacuum pressure. For products sensitive to light and moisture, cold forming, where an aluminium-based laminate is pressed into a mould without the use of heat.
Product placement: The formed blister sheet moves along the production line and the products are placed into individual cavities. This can be done manually or by automated machines.
Welding: A backing material, which can be printed with product information and branding, is placed on the filled blisters. Heat and pressure are then applied to seal the backing to the plastic blister, creating a secure and tamper-proof package.
Cutting and perforation: Finally, the sealed sheets are cut into individual blister packs. Perforations can also be added between packs to make them easier to separate.

Advantages of blister packaging

Type of packaging blister pack offer several key benefits:

Product protection: They provide excellent protection against moisture, light, oxygen and contamination, extending the shelf life of the contents.
Tamper-proof: The closed design makes it immediately visible whether the package has been opened or tampered with, increasing consumer safety.
Product visibility: Clear plastic allows consumers to see the product before purchasing, which can be a significant marketing advantage.
Dosing precision (in pharmacy): For medications, blisters provide separate, single doses, helping patients adhere to treatment recommendations.
Personalization and branding: The cardboard backing offers plenty of space for logos, instructions and other important information. The blister itself can be molded into custom shapes to perfectly fit the product.
Profitability: For high-volume production, blister packaging can be a very economical choice.
