PMD

Plastic containers and trays used for biscuits, mushrooms, cherry tomatoes, strawberries, berries, etc. are all examples of plastic household packaging (the P in PMD) and, when empty, they belong in the PMD bag.
Was the container sealed with a plastic film? Then that film is part of the packaging and is also to be sorted in the blue bag. Make sure to seperate the container from the film first.
