An Overview of Blister Packaging

Every manufacturer wants to create eye-catching products and keep them secure till they reach customers' hands. That's why the packaging is an indispensable part of a product.

Among the various options available, blister packaging stands out for its capability of providing both style and safety. Thanks to its transparent appeal and robust design, blister packaging has revolutionized how products are showcased and preserved.

If you're looking to figure out why this packaging solution has become a favored choice for businesses across the globe, you've come to the right place. Whether you're a curious learner or a forward-thinking manufacturer, this handy guide will help you navigate the world of blister packaging. Let's dive right in!

What is Blister Packaging?

Blister packaging is produced by a thermoforming process. During the process, a plastic or aluminum foil sheet is heated and molded to form single or multiple bubbles or pockets known as blisters.

Then the blisters hold a product and are heat-sealed to a rigid backing material, such as cardboard or aluminum foil. The product is securely sealed within the blister to protect it from damage, tampering, and contamination.

Blister packaging is used extensively in various industries, such as pharmaceuticals, electronics, consumer goods, and retail. It can be produced using various methods, including heat sealing, cold sealing, or high-frequency welding, depending on the materials involved and the requirements of the product.

This popular packaging solution offers a range of benefits, such as:

• Product visibility
• Product protection
• Tamper resistance
• Convenience
• Customization and branding

Types of Blister Packaging

Based on the combination of materials used, this popular packaging method can be categorized into the following types:

1. Plastic-Paperboard. This type combines a plastic blister cavity with a paper-based backing. The paperboard offers additional support and a printable surface for branding and product information.

2. Plastic-Plastic. Both the blister and the backing are made of clear plastic materials, offering good product visibility. The packaging is widely used for various consumer goods.

3. Aluminum-Plastic. This type combines a plastic blister pack with an aluminum foil backing. The aluminum foil effectively protects the product against external elements. It is also known as Alu-PVC blister packaging, commonly used in the pharmaceutical industry.

4. Aluminum-Aluminum. It's also known as Alu-Alu blister packaging in the pharmaceutical industry. The packaging is produced by cold forming and comprises two layers of aluminum foil sealed together. It is ideal for packaging sensitive pharmaceutical products.

Blister Packaging Process

If you've read this far, it seems that you now understand the definition and various types of blister packaging. Now you may be wondering about how to make blister packs. Here's a step-by-step description of the blister packaging process:

1. Forming. Blister cavities or pockets are created by a forming die, whether thermoforming or cold forming.

2. Filling. Products to be packaged are placed into the formed cavities at the filling station of a blister packaging machine.

3. Sealing. After the products are filled, the backing material (usually a paperboard, foil, or plastic sheet) is heat-sealed to the blister cavity to enclose the product securely.

4. Perforating and Cutting. The sealed blister packs are then perforated and cut using precision cutting dies.

What is a Blister Packaging Machine?

To understand blister packaging better, it's crucial to be familiar with the equipment used for the process - the blister packaging machine. A blister packaging machine is designed to streamline the packaging process for products sold in blister packs.

The blister packaging machines are capable of:

• Improving productivity, ensuring consistent packaging;
• Helping to reduce damage and minimize waste compared to manual operation;
• Cutting down on labor costs;
• Enhancing the overall quality and consistency of the packaging process.
