PVC / PVDC Plastic Cling Wrap

⚠️ USE WITH CAUTION

Wrapping food and covering bowls in the fridge or microwave

Materials

Polyvinyl chloride (PVC) or polyvinylidene chloride (PVDC)

Common claims

Clings on contact
Airtight seal
Microwave safe

Concerns / watch-outs

PVC cling wraps contain plasticizers (some phthalates) that can migrate into fatty foods
Microwaving fatty foods in contact with PVC wrap increases migration risk

Cleaner alternatives

Styrofoam / Polystyrene Food Container

☣️ TOXIC CHEMICALS

Disposable takeout containers and single-use food packaging

Materials

Expanded polystyrene (EPS, recycling #6)

Common claims

Lightweight insulation
Cost-effective packaging

Concerns / watch-outs

Styrene — the building block of polystyrene — is classified as a possible human carcinogen (IARC Group 2B)
Leaches styrene into fatty or hot foods
Essentially non-recyclable and environmentally persistent

Notes

One of the worst food contact materials for both health and environmental impact. Avoid using for hot or fatty foods. Opt out whenever possible in favor of glass, stainless, or even HDPE.
