Plastics to Avoid When Microwaving Food
Polystyrene (styrofoam) — #6 — Not heat tolerant. Polycarbonate — #7 — Many formulations may contain BPA. Polyvinyl Chloride (PVC) — #3 — Rarely used for foods. High-Density Polyethylene (HDPE) — #2 — While generally safe, HDPE is less heat-tolerant.
Generally, food grade plastics will be labeled with either 1, 2, 4, or 5. These refer to polyethylene terephthalate (PET or PETE), high-density polyethylene (HDPE), low-density polyethylene (LDPE), and polypropylene (PP), respectively. (Learn more about food grade plastics here.)
