Many people collect recyclable plastic containers and bundle them in thin plastic bags sold to hold co-mingled recyclables. When it comes time to recycle these containers, you just knot the top and toss the whole bag full of recyclables right into the bin. But here’s the problem: Even if the thin plastic bag is recyclable, your recycling center would prefer you not use them. When the plastic bags are ripped open to let the plastic containers free, the thin plastic can get loose and jam recycling equipment. They can also blow away and contaminate other recyclables like paper, cardboard and metal.
