I always try to use reusable containers to store my food, but sometimes a situation simply calls for cling wrap. In these cases, I prefer to use OP Biodegradable Cling Wrap (OP 生物分解保鮮膜), available at most supermarkets in Taipei.
When I first discovered this brand of cling wrap I was pretty excited. I didn't even know they could make plastic wrap that is biodegradable. According to the label, the plastic contains no chlorine or plasticizers that would emit toxic fumes under high heat, and it is 100% biodegradable, meaning it will eventually decompose over time when discarded.
