Blister packaging is everywhere, especially when it comes to things like medicine and everyday items. It keeps products safe, easy to see, and neatly packed. But what exactly is it, and why do so many brands use it?
In this post, we’re breaking it all down. You’ll learn what blister packaging is, how it’s used, the different types out there, and why it’s such a go-to option for so many industries. Whether you’re just curious or looking for the right packaging for your own product, this guide will give you a clear and simple look at how it all works.
What Is Blister Packaging?
Blister packaging is a type of packaging where a product is sealed inside a clear plastic bubble that’s shaped to fit it. That bubble is then attached to a flat piece of cardboard or foil. It’s called “blister” packaging because the plastic sticks out like a little blister over the product.
The clear plastic keeps the item in place and lets you see exactly what you’re getting. The backing, usually cardboard or foil, gives it support and often has helpful info like instructions or branding.
This kind of packaging is common for small items like toys, tools, or medicine. It’s a simple and effective way to keep things safe, easy to find, and ready to use.
Common Uses of Blister Packaging
Blister packaging is used in many different products across various industries. Let’s take a closer look at some of the most common uses:
Pharmaceuticals
Blister packaging is commonly used for medications like pills and capsules. The plastic compartments protect each pill from damage, moisture, or being crushed. It also makes it easy to manage portions since each dose is separated and ready to use. Many blister packs also include tamper-evident features, which help ensure the product has not been opened before purchase.
Consumer Goods
You’ve likely seen blister packaging on everyday items such as batteries, toys, and small tools. The clear plastic allows customers to see exactly what they are purchasing while keeping the product secure inside. It’s an excellent way to package small items that need extra protection or that need to be clearly visible on store shelves.
Food and Personal Care Items
Blister packaging is also used for some food products, like single-serve snacks, and personal care items such as razors or toothbrushes. It helps keep these products fresh and clean, while offering an attractive display on store shelves. Whether it’s a snack or a personal care item, blister packaging ensures the product stays safe, secure, and ready for use.
Overall, blister packaging is an effective way to showcase products while keeping them protected. Its clear design is a big advantage, especially in retail, where customers can see exactly what they’re purchasing. Plus, its durable design helps maintain the quality and condition of the product.
Types of Blister Packaging
Blister packaging comes in a few different types, each designed for specific needs. Here’s a simple guide to the most common ones:
Thermoformed Blisters
This is the most common type of blister packaging. It’s made by heating a plastic sheet until it softens, then molding it into shape. The plastic is then sealed to a backing, like paperboard or foil.
What it’s used for: Thermoformed blisters are great for packaging things like medications, small electronics, and toys. Their ability to be molded into different shapes makes them very versatile.
Cold-formed Blisters
Cold-formed blister packaging doesn’t need heat. Instead, a thicker plastic is pressed into a mold under pressure to create a stronger seal. This method is ideal for products that need extra protection, like moisture-sensitive medications.
What it’s used for: Cold-formed blisters are commonly used for pharmaceuticals, especially sensitive medications. The stronger seal helps protect the product from things like humidity and light.
Clamshell Packaging

Aluminum Foil
Aluminum foil is commonly used as the backing for blister packs, especially for pharmaceuticals. It keeps moisture, light, and air out, protecting sensitive products. Plus, it gives the packaging a sleek, shiny look.
Recyclability: Aluminum is highly recyclable and can be reused over and over without losing quality. Recycling aluminum helps conserve energy and reduces environmental impact.
Paperboard
Paperboard is often used as the backing in blister packs for both consumer goods and pharmaceutical products. It’s strong, easy to print on, and ideal for including branding or instructions.
Recyclability: Paperboard is easily recyclable and is accepted by most curbside recycling programs. It’s more sustainable than plastic or foil, especially when made from recycled materials.
Sustainability Concerns
While blister packaging has its benefits, there are concerns about its environmental impact. Plastics like PVC and PET take a long time to break down in landfills, and not all of them are easy to recycle. On the other hand, aluminum and paperboard are generally more recyclable. Still, the sustainability of blister packaging depends on how it’s made and disposed of. As manufacturers search for greener options, there’s a growing push for biodegradable materials and reducing plastic use.
If sustainability matters to you, it’s worth looking for packaging made from more recyclable materials or renewable sources. Every small change can make a difference in reducing packaging waste and its impact on the environment.
How Blister Packaging is Made
Blister packaging is a protective way of holding products in place. The process involves shaping plastic into a blister and sealing it to a backing to keep the product safe. Let’s break down how it’s done:
The Manufacturing Process
The process starts with a flat sheet of plastic. The plastic is either heated or pressed into a mold to form the blister. Then, the blister is sealed to a backing (usually paperboard or foil) to secure the product.
Here’s a simple overview of the steps involved:
- Heating or pressing the plastic until it becomes soft enough to shape.
- Shaping the plastic into a cavity that holds the product (this forms the “blister”).
- Sealing the plastic to the backing, which can be paperboard, foil, or sometimes another layer of plastic.
- Cutting the blister pack into the correct size, often into individual units for retail.
Cold Forming vs. Thermoforming
There are two main ways to create blister packaging: cold forming and thermoforming. Here’s how they differ:
Thermoforming
In thermoforming, a plastic sheet is heated until it’s soft and flexible. Then it’s molded into the desired shape. Once it’s shaped, it’s sealed to a backing (like paperboard or aluminum foil) using heat.
When it’s used: Thermoforming is a fast and cost-effective method, making it ideal for things like medications, small electronics, and toys.
Cold Forming
Cold forming uses high pressure to press the plastic into a mold instead of heat. This creates a stronger, more durable seal, and the plastic is often thicker.
When it’s used: Cold-formed blisters are better for items that need extra protection, like sensitive medications or high-end electronics. The stronger seal helps protect against moisture, light, and air, which could damage the product.
Both methods have their advantages. The choice depends on the product’s needs, whether it requires extra strength or if a quicker, more cost-effective solution works better.
Now you have a better understanding of how blister packaging is made and the difference between the two main methods!
