Disposable Stretch Food Covers.

These Stretch Food Covers replace the cling film that tears crooked and sticks to itself, using an elasticated edge that pulls down over a rim the same way a shower cap does. One motion seals a bowl, a plate, a cut melon, or a half-used can, with no tearing, no static, and no gaps around the edge.

The film is clear, so nothing has to be lifted to find out what's inside, and because the edge grips instead of clinging, it holds on square dishes and odd shapes that wrap slides straight off. Each cover stretches to fit anything from a small ramekin to a large mixing bowl, and comes away in one piece instead of peeling off in torn strips.
