Materials Certificates & Declarations


We take materials sourcing seriously and make sure we're happy with their safety, quality and origin, so we require proof from our suppliers. Here they are! (We've blanked out some supplier information because it is business-sensitive).

Buy with confidence

In addition to certification testing, the all-natural raw materials that go into our wraps are approved as safe in food by the US Food and Drug Administration, the UK's Food Standards Agency and the European Food Safety Authority.

The OEKO-TEX Certificates for our fabric mean they have passed stringent tests for dozens of harmful substances (like formaldehyde, lead, arsenic, pesticides, carcinogens, etc.) to ensure that the fabrics are in no way harmful to health.

Some of our fabrics are additionally REACH Certified (EU REACH regulation (EC) No 1907/2006).

More about our Certified Food Safe Test Results

It's taking the world's regulators a little time to catch up with our move towards sustainable, reusable alternatives to plastic, and we’re not waiting until they do…

We've made sure that we know (and you know!) that our food wraps are completely safe to use on food

In addition to only using raw ingredients that the US, UK and European food safety agencies have approved as safe in food, AND using fabrics that are OEKO-TEX Certified as having been extensively tested for any harmful substances, we have had our finished products rigorously tested by an independent product testing facility in the UK.

We have passed both the migration and metal/element release tests

This means that the ingredients that make up our wraps (which are: all-natural beeswax, damar resin, extra-virgin olive oil and 100% cotton fabric) will not be passed on to your food, as per Standard EN1186. The scientists call this "migration" and our wraps scored very well on this: less than 3.5mg/dm². To put that into context, plastic food packaging is allowed to migrate up to 10mg/dm² of whatever it’s made from to your food.

Our wraps passed the tests for 23 metals and other elements like arsenic, lead and mercury (yuck!)

Our wraps fully comply with EU Regulations 10/2011EU as amended by (EU) 2020/1245. That's the regulation on plastic materials and articles intended to come into contact with food.

In fact, there is absolutely no trace of arsenic, lead or mercury in our wraps (the regulation allows for tiny amounts in plastic food packaging!)

Our wraps have passed an official sensory evaluation for smell and taste with flying colours!

They transfer no perceptible smell or taste to your food according to the official sniffers and tasters at the independent testing facility.
