If you package food yourself, you must use packaging that’s suitable for food use. Suitable packaging is marked ‘for food contact’ or has a symbol on it that looks like a wine glass and a fork.
There are special rules for using plastics, ceramics or cellophane for packaging. You must have written evidence that you’ve kept to them.
This is known as a ‘declaration of compliance’ and you can get it from your packaging supplier. You also have to get one if you buy food that’s already packaged for sale in any of those materials.
