If you’re exploring blister packaging for your products, the first question you probably have is: what materials are used in blister packaging ?
The answer depends on clarity, barrier protection, sustainability, and of course, cost.
As Pakoro, we’ve helped hundreds of businesses select the right material mix, and I’ll guide you through the essentials so you can make a smart decision quickly.
Understanding blister packaging
Blister packaging works by heating a plastic sheet, forming it into a cavity that holds your product, and sealing it with a backing—usually paperboard or aluminum foil.
This design lets your customers see the product clearly while also protecting it from tampering.
It’s why you see blister packs everywhere, from over-the-counter medicine to electronics accessories.
The most common choices you’ll encounter
In reality, most blister packs are made with a handful of materials.
PVC is still the most widely used because it forms easily and keeps costs low.
However, if your brand or retailers are pushing for sustainability, PET or recycled RPET will be more attractive.
They provide brilliant clarity and are accepted in many recycling streams.
When you need something tougher, especially for medical devices, COP/COC (cyclic olefin polymers) deliver both precision forming and clean chemistry.
And if you’re in pharmaceuticals, you’ll often hear about PVC coated with PVDC, which boosts the barrier against moisture and oxygen.
For the most sensitive drugs, PCTFE laminates come into play, because they offer extremely low moisture transmission and longer shelf life.
Don’t forget the lidding
The cavity is only half of the package.
On the back, you’ll either have paperboard (perfect for retail because it allows full branding and hanging slots) or aluminum foil (standard in pharma because it allows push-through tablets and tamper resistance).
Both choices impact recyclability and user experience, so it’s not just about the front plastic.
Sustainability and new directions
Today, more buyers ask us, “Can blister packaging be recyclable?”
The good news is yes, when you move to mono-material PET systems or use RPET content.
Some industries are even experimenting with paper-based blisters for a low-plastic story, though protection is not as strong.
If your market requires eco claims, Pakoro can design blister packs that balance protection with sustainability goals.
How to decide for your product
Instead of overwhelming you with technical charts, here’s a practical way to think:
- If your product just needs visibility and low cost → PVC or PET.
- If moisture and oxygen are a concern → PVC-PVDC or even PCTFE.
- If sustainability is non-negotiable → PET or RPET.
- If you’re in medical or high-precision sectors → COP/COC.
By asking these questions, you quickly narrow down the right fit without wasting weeks testing unsuitable options.
