This morning I finished off a packet of cranberries. I'm collecting plastic film for recycling with Polyprint, and I know they can take types 2 and 4, which Waste Online tells me is high- and low-density polyethylene, or HDPE and LDPE. But I'm still not sure whether that covers my cranberry bag - websites giving examples of types of plastic usually just describe HDPE as used in opaque milk bottles, and LDPE as carrier bags. So, I check the packet, and sure enough there is a "recycling information" panel. Woohoo!
It says: "Bag: plastic. Recyclable where facilities exist."
