The Green Guide put out by National Geographic recommended the Preserve Food Storage containers when you need to store leftovers or other types of food. So if you worry about plastics and food storage, then you may want to refer to the Green Guide website as it gives a lot of information on this subject.
For instance, each type of plastic is given a number corresponding to the type of resin used in production. Most of your storage containers will have a number five on the bottom inside the recycling logo, which means it is polypropylene. Cling wrap and storage bags are number four, and milk jugs are number two. All of these types of plastic are recommended.
Plastic with a number four is PVC and is frequently used in cling wraps for meats at the supermarket and delis. This should generally be avoided according to the Green Guide, but I don’t know how many people would follow its recommendation of slicing off a thin layer where food came into contact with the plastic. I probably won’t go that far.
Preserve Food Storage also offers some square storage containers for sandwiches and leftovers that should inspire everyone who takes their lunch to work to upgrade. It is true that these product options are a bit more expensive, but the Green Guide also recommends Ziplock storage containers, which are affordable and easily found at supermarkets.
