Have you ever wondered why clamshell containers are popping up everywhere in the food packaging world?
They’re showing up in restaurants, takeaway joints, and even supermarkets.
You’ve seen them: those sturdy, hinged containers, typically used for sandwiches, salads, or burgers. But what’s the deal? Why is everyone talking about them?
In this guide, I’ll break down clamshell packaging – what it is, why it’s so popular, and how it could totally change your food packaging game.
Let’s dive in.
What Is Clamshell Packaging?
Put simply, clamshell packaging is a hinged, two-piece container that “closes” like a clam shell.
You open it up, pop your food in, and snap it shut.
It’s made to protect your food while being easy for customers to open, close, and carry.
You’ve probably already used one without even realising it – especially if you’ve ever grabbed a takeaway salad or a sandwich from your local cafe.

Clamshells come in different materials, and it’s important to pick the right one based on what you’re packing.
Here’s a quick rundown:

- Solid barrier to keep food fresh.
2. Foam Clamshells

4. PLA Clamshells
- Biodegradable and compostable.

Why Do Clamshells Work So Well for Food Packaging?
1. Convenience
Clamshells are easy to pack.
Just pop your food in, snap it shut, and you’re good to go.
2. Efficiency
No need to search for lids, tape, or extra packing materials.
The built-in clasp or latch makes it a one-step process.
3. Easy Access for Consumers
Because of the hinge design, customers can open and close them with ease.
This is perfect for takeaway food. No messing around.
4. Re-sealable & Display-Friendly
The clamshell design keeps food fresh, and you can even seal it back up for display or storage.
Perfect for deli counters, or serving fresh sandwiches or pastries at the store.
5. Enhanced Protection
If you need to make sure your food isn’t tampered with, the clamshell is great for that.
The latch mechanism can be sealed with a sticker for added security.
When Should You Use Clamshell Containers?
It’s all about picking the right type of clamshell container for the right food.
Here are some examples of when clamshell packaging is your best friend:
Small Clamshell Containers (6-inch)
Ideal for individual items like sandwiches, burgers, and small cakes.
These are the takeaway boxes you grab when you’re in a rush for lunch.
Rectangular Clamshell Containers
Perfect for BBQs, skewered meats, or pre-cut fruit.
They’re also great for snacks that need a little space, like sushi or fruit salads.
Larger Square Clamshell Containers (8-9 inch)
These are your go-to containers for salads, pre-cut fruits, or large deli meals.
If you’re packing multiple sides or need some compartments, a clamshell with sections will make life easier.
The Environmental Impact of Clamshell Packaging
Here’s the thing: clamshell packaging can either be a saviour or a villain when it comes to the environment.
Sustainable Clamshells
Made from bagasse (sugarcane pulp) or PLA (plant-based plastics), these are biodegradable and compostable.
They break down naturally, which means less waste in the long run.
Non-Recyclable Clamshells
Unfortunately, many plastic clamshells aren’t recyclable or biodegradable.
If you’re aiming for a greener future, these aren’t your best bet.
How to Open a Clamshell Container?
Opening a clamshell container is super simple:
- Find the hinge or latch.
- Gently pull it apart.
- Boom – your food’s ready to eat!
That’s it! No wrestling with tricky lids or struggling to tear off plastic.
Perfect for on-the-go meals, picnics, or restaurant takeaways.
Future Trends: What’s Next for Clamshell Packaging?
1. Sustainability Takes Centre Stage
The push for eco-friendly clamshells is only going to get stronger.
Consumers want brands that care about the environment, and compostable clamshells are the answer.
2. Customisation
If you’ve been thinking about custom packaging for your business, clamshells are a great option.
Think branded logos, quirky designs, or messages on the lid. Customisation can make a big impact, especially in the takeaway food space.
3. Cost vs. Eco-friendliness
Cost is always a factor, but as more sustainable options hit the market, you’ll see the price of things like bagasse clamshells drop.
Brands are realising they don’t have to sacrifice the planet for savings. It’s about striking that balance.
