What do they call the ';clear plastic sticker stuff'; that is wrapped on electronics when new?

it's like sticker, when you buy a new laptop or a mobile phone you can take it off easily they're usually a see-through material. I dont know what they're called and need to buy some as i'm selling my home-made radios but cant find this packaging stuff to make it look proffesional.
