> Japanese cling wrap

Careful with this one. As I understand it, most consumer cling wrap in western markets is polyethylene film, which is made without plasticizers. But Japanese cling wrap (and the stuff at Costco) is plasticized PVC film, and those plasticizers may well be soluble in your food. The market is supposedly shifting toward safer plasticizers, but I personally would rather not place soft, plasticized plastics in prolonged, direct contact with my food.
