DYK- although frozen food boxes are paper products, most of them can’t be recycled? These boxes (aka wet-strength paperboard) are just like recyclable boxes- with one difference. The paper is layered with polyethylene (LDPE) plastic to keep the box from getting soggy and to prevent freezer burn. Soda & beer cartons are made of it too.
It’s difficult to separate the plastic from the paperboard and some municipalities can’t accept it as recycling. And because of the plastic, it can’t be composted either. So check the box for a recycling symbol and your local requirements, but otherwise, frozen food boxes go in the trash.
