What is cork?

Cork is the outer bark of the cork oak tree. Long used by the wine industry to seal their bottles cork is also used with push pins to hold notes. For more detailed information, please see our About Cork page.

Isn’t cork endangered?

Cork cannot be endangered if it is being utilized. The cork oak tree is different from other trees in its harvesting – the cork is peeled by hand.  Peeling the bark helps the tree to live to 200 years or more. Once peeled the bark grows back in 7 to 9 years ready to be harvested again. Cork is truly a renewable material and its harvesting has a minimal carbon footprint.

Cork will be endangered if we discontinue using it. The non-utilization of cork makes it less valuable and therefore the forests less valuable. If the forests are less valuable they maybe cut down to make way for more profitable agriculture or even to plant trees used for paper. The cork forest is home to many endangered animals and is a truly diverse and unique ecosystem. To remove the forest would remove the economy of many towns and cities, not to mention the permanent removal of unique animals. To read more about the forest please visit the World Wildlife Foundation.

We must also remember that as a tree the cork oak tree helps to remove carbon dioxide from the atmosphere and replace it with oxygen. 

What are the benefits of cork?

Cork is a versatile and under-rated material – but CoolCorC is changing all that. Cork is hypoallergenic, waterproof, stain resistant, highly insulative, biodegradable and beautiful. These are many reasons to rethink how cork is used and CoolCorC is doing just that!

How do CoolCorC cup sleeves insulate so well?

Cork! Our sleeves are made entirely out of cork which is highly insulative. Click here to see just how great the CoolCorC cup sleeve works.

What do you mean by saying cork is "biodegradable"?

Because cork is bark it will naturally degrade over time.  Just like fallen trees or leaves in a forest degrade so will cork bark.

What is the difference between the CoolCorC disposable and reusable sleeve?

The disposable sleeve is intended for single use however with gently use it can be used for many more.  The reusable sleeve is intended for everyday use – it is more durable than the disposable sleeve. Plus, the reusable sleeve utilizes cork fabric - it is similar in texture as leather but comes from a tree!

Minimum orders for the CoolCorC disposable sleeve are 1 box (1000 sleeves).
