Is sandwich wrap really necessary? Though sandwich wrap is very useful (like I mentioned), when you think about it, it isn’t extremely necessary. Yes, it does keep food fresh and together, but environmentally, it isn’t very friendly. Unlike paper, plastic takes lots of time to decompose and that pollutes everything around us. Instead of plastic wrap, we could perhaps use paper or containers to keep from rotting/falling out or apart. In my opinion, paper would decompose more quickly and containers can be reused over, and over again, keeping our environment clean and safe for everyone.
