Say hello to cardboard, the sustainable packaging choice

At Beyond the Box, we believe cardboard is the UK’s sustainable packaging choice and the answer to the country’s packaging dilemma. But what exactly is it – and why is it so important?

Cardboard, also known as corrugated cardboard, is a specially engineered material made from paper pulp. It’s made up of different components that work together to make it strong, lightweight and versatile. You might recognise the wavy shape of its distinctive fluting (or corrugation). This is often sandwiched between two layers of board.

What’s cardboard used for?

All this makes cardboard the perfect sustainable packaging material – and you might be using it even more than you realise! Chances are, cardboard will be used to protect the online deliveries that arrive on your doorstep, help you store your Christmas decorations safely in the loft or play a major part in helping you pack up and move to a new house.

In fact, cardboard is so widely used that almost all items we buy have been wrapped in a cardboard packaging at some point during their lifetime.

Eco-friendly packaging: Why is cardboard important?

Nowadays, packaging is as important as it’s ever been – and across the world more and more of us are seeking eco-friendly options to reduce the environmental impact of the packaging that we all use and need. That’s where cardboard comes in.

As the UK’s most sustainable packaging choice, cardboard is:


Cardboard is 100% recyclable, and more than 80% of the cardboard we use in the UK is recycled – that’s the best recycling record of any packaging material.


Cardboard is a renewable packaging material as paper – which is used to create it – is made from a natural, renewable resource, wood. Wood can be produced in an endless cycle thanks to sustainable forest management. Find out more on the Beyond the Box blog


Whether you’re packing up and moving house, keeping the kids entertained with a life-sized fort, or providing a comfy bed for a family pet, cardboard is easily reused in the home. Just don’t forget to recycle it once you’re finished!


Recycling is without a doubt the best way to dispose of cardboard, but the good news is that if any does end up in landfill, it’s totally biodegradable.

What’s cardboard made of?

Cardboard is typically created using three carefully assembled layers of paper. These layers include an inside and outside liner with a corrugated layer – or fluting – in the middle. It’s this simple but innovative design that makes cardboard packaging so robust. The flutes prove effective insulation from outside temperatures, whilst also keeping the structure nice and sturdy.

What are the different types of cardboard?
