Plastic wrap was a kitchen essential for me my entire life. I used it to wrap up a half-used onion; to cover a large bowl of lentil salad I had made for the week; to wrap a sandwich tightly for safe passage in my bag to work. Every few months I’d run out and immediately buy a new roll, considering it a staple kitchen item, like butter, olive oil and salt. What I really needed were reusable plastic wrap alternatives.
