What Is Thermoformed Packaging and How Does It Work?
Have you ever wondered why so many products on Australian shelves come in sleek, clear plastic forms that showcase the contents perfectly? That’s the result of thermoformed packaging — a smart, efficient solution for retail and industrial packaging alike.
Thermoformed packaging uses heat and pressure to shape plastic into custom-moulded containers. From delicate bakery items to high-end electronics, this method offers flexibility, durability, and shelf appeal — all while being cost-effective.
Let’s break down how it works, how it compares to other packaging methods, and why it might be the right fit for your business.
What Is Thermoforming?
Thermoforming is a manufacturing process where a plastic sheet is heated until pliable, then shaped over a mould using vacuum or pressure. Once cooled, the plastic retains its new form — whether that’s a tray, clamshell, insert, or blister pack.
It’s widely used across industries due to its:
- Low tooling costs compared to injection moulding
- Fast turnaround times for medium to high production runs
- Excellent clarity and visibility for retail packaging
- Compatibility with recyclable materials like PET and RPET
Whether you’re packaging chocolate, cosmetics, tools, or electronics, thermoformed packaging can be tailored to fit and protect your product.
Quick Answer
Thermoformed packaging is made by heating a plastic sheet and forming it over a mould to create a custom container. It’s ideal for retail and industrial use due to its:
- Clear presentation
- Cost-effective tooling
- Fast production
- Custom shapes for product protection
It’s a smart solution for Australian businesses seeking efficient plastic packaging.
Thermoformed vs Injection-Moulded Packaging
At first glance, both thermoformed and injection-moulded packaging may look similar — but the way they’re made (and the costs involved) are very different.
| Feature | Thermoformed Packaging | Injection-Moulded Packaging |
| Tooling Cost | Lower | Higher (steel/aluminium tooling) |
| Lead Time | Faster | Slower (longer setup) |
| Material Waste | Less | More (excess injection points) |
| Best For | Medium-large runs, custom inserts, display packaging | High-volume identical parts |
| Clarity & Appearance | High (especially PET) | Variable, often opaque |
Thermoforming is often preferred for packaging that needs a clear, customised fit without the high upfront tooling costs.
