Because You Asked: Is Cling Wrap Recyclable?

By Recyclebank |

Think you can put cling wrap in with your plastic bags? Think again — this stretchy #3 plastic is landfill-bound.

Dear Recyclebank,

What is cling wrap made out of, and is it recyclable?

–Mariah O.

Dear Mariah,

Cling wrap, also known as cling film, plastic wrap, food wrap, or the genericized brands Saran™ wrap or Glad® wrap, is the thin, plastic film commonly used for sealing food in containers to keep fresh and delay spoilage. They are used widely in homes, restaurants, catering businesses, and supermarkets, for wrapping and protecting food from contamination and prolonging freshness. Most plastic wrap is made from polyvinyl chloride (PVC) or polyvinylidene chloride (PVdC), categorized as plastic number 3. But due to health concerns regarding phthalates, the chemical plasticizers that make PVC softer and more flexible, and the environmental concerns of dioxins from chlorine, low-density polyethylene (LDPE, plastic number 4) has become a popular PVC alternative.

Some municipalities may accept plastic #3 bottles (your softer, more flexible plastic cooking oil bottles may be #3 plastic). However, #3 films should not be put in the recycling bin — not only is cling wrap usually soiled with food, contaminating other valuable recyclables, but like plastic bags, it’s also likely to jam the machinery at MRFs, costing processing time and money. Unfortunately, cling wrap can’t be recycled along with other plastic films such as plastic bags, either; the chemicals and resins added to make the cling wrap “clingy” and stretchable cannot be removed, making it too complex a plastic to recycle. With those options out, used cling wrap is unfortunately headed for the incinerator or landfill.

The best way to avoid sending cling wrap to the landfill is to limit your use of it. Try to avoid buying food wrapped in plastic — look for fresh ingredients from your local farmers markets or CSA instead, and buy things in bulk to reduce overall packaging. At home, use reusable containers and recyclable, sealable bags for things like meats, cheeses, and other prepared foods that are normally wrapped in plastic. If using cling wrap is unavoidable for you, look into compostable alternatives, like BioBag’s cling wrap, which is made from plant resins.

    I agree with Mariana --reusable containers. Save some of those glass and plastic jars that your grocery store products come in and you won't even have to buy all that "stuff" which may end up in the landfill after prolonged usage.

    I don’t use cling wrap. I use Tupperware or tin foil, etc.

    You can buy a package of covers with elasticized edges - they are round, come in graduated sizes, and are sturdy and can be washed and reused.

    you can make a reusable cover by melting bees wax over cotton fabric. Your body heat remelts the wax to mold it around bowls and it can be rinsed and reused.

    You can buy what looks like a head thing for the shower with elastic.. It comes in different sizes AND fits over any bowl no matter the shape. OR purchase glass bottom & tops
