In the last few months I’ve suddenly started seeing many products made from “cork fabric” or “cork leather” and also “vegan leather.” I ignored this vegan leather for a while because in the past vegan leather often mean PVC vinyl, which is not a good substitute, but when I found out it was actually cork, I took a look at it.

You’ve probably seen cork in many consumer products such as wine stoppers and bulletin boards.

The cork used to make cork fabric is thin cork shavings obtained directly from the bark of the cork oak tree. These shavings are glued to a fabric backing to make a fabric that feels very much like leather, but is plant-based.

I called a manufacturer of cork fabric and asked them about the process of making it. The thin layer of cork is “laminated” to a fabric backing using an “environmentally-friendly” adhesive. The standard backing fabric is a polyester/cotton blend.

The company I talked with did not have much information about the laminating process for me to evaluate. This material is apparently made to a vegan standard and has some environmental benefit, but it doesn’t appear to be made with a nontoxic intent.

I have a sample of this fabric, sent from a retailer of products made from it. I just have a small swatch, but even that piece has enough odor to it that I can’t recommend it as being nontoxic. It smells like some kind of fabric finish. I actually had to take the swatch to my garbage can outdoors, and get it out of the house.

So if you see products made from this material, now you know what it is
