If you've ever struggled to get your plastic wrap to stick, Cover Blubber is a useful alternative. The elasticized, reusable food wrap provides an air-tight seal that will protect your leftovers and sliced produce. The product could also be used on open paint cans, science experiments and other crafty uses.
Four different size-specific colors are available from ThinkGeek. The food-safe sticky rubber is EU and FDA approved and doesn't contain any BPA or Phthalates. The plastic wrap will work for food tossed in the fridge or freezer. While the reusable wrap replaces disposable plastic wrap and container lids, it does not travel well and is not microwave or dishwasher safe. The material is stretchy, but it works best on uniformly shaped containers (which means it will be weird on rectangular dishes).
