Introducing our first sustainable coolbox

By The Modern Milkman on May 27th, 2021

Our prototype cardboard coolbox is ready for trial

We’ll be rolling this prototype out in a limited edition trial and use your feedback to further our sustainable coolbox technology. There’s not been this much excitement since NASA launched their first space shuttle into space. The new coolbox has impressive thermal capabilities and will hopefully help to keep your milk and groceries cool and protected during the summer. But we won’t know for sure how effective and durable it is until you’ve put it through its paces. 

We’d love your feedback

All we ask for in return for the prototype coolbox is your feedback to improve and develop it further. We’ll send more details about our coolbox survey in a couple of weeks after you’ve had a chance to use it properly, followed by another survey at the end of the summer. 

How to use your coolbox

Our sustainable coolbox uses multi-layered cardboard to trap pockets of air and insulate your groceries, but you’ll need to make it cold inside (as with any coolbox).

You can cool your box using:

  • Reusable cool blocks and cool packs
  • Bottle chilling sleeves
  • Frozen water containers

Be careful not to overfill your containers when putting them in the freezer, as water expands when it turns to ice. Also, don’t use glass, as it might crack.

How to look after your coolbox

Try to minimise your coolboxes exposure to water. They’re surprisingly durable, but you might want to keep it away from any standing water (near drains etc) and bring it inside in between deliveries to extend its lifespan. You could also prop it up off the ground with bricks, wood or whatever you have lying around (ensuring it’s supported in the middle and the sides). If it’s still in good shape when winter comes, you can flat pack it away, ready for next summer. If it’s seen better days, you can recycle it in your paper bin, ready to be reincarnated as a book, toilet paper, or maybe just another box.
