All plastic packaging should be clearly imprinted with the nature of the plastic used and its recycling code. E.g. PET 1.
Why is this important?
At present a large proportion of food packaging does not provide the consumer with recycling imformation either on the plastic tray, or the accompaning paper information.
This lack of information means that a lot of recyclable plastic still goes to landfill. Conversely consumers may be presenting plastics for recycling having assumed them as recyclable when they are not.
