With school back in session, who doesn’t have lunch on the brain? As if figuring out what food to make that the kids will actually eat weren’t enough to contend with, there’s also the key issue of what to pack it in.For most, the material of choice is plastic; it’s lightweight and it won’t break. But some plastics contain BPA or phthalates, two chemicals that fail health class, among other unsafe substances. Others are a lot safer. Plastic-free alternatives include cotton or hemp sandwich bags, plus shatterproof glass and stainless steel containers.If you or your school insists on using plastics, the two safest kinds for lunch storage are high-density polyethylene (HDPE)—marked with recycling code #2—and polypropylene (PP) or recycling code #5. Both of these plastics have not been shown to leach their chemical components into foods. Low-density polyethylene (LDPE), code #4, commonly used for plastic wraps, is also a reasonable choice, though not reusable. Polyethylene terephthalate (PETE or code #1), polyvinyl chloride (PVC, code #3), polystyrene (PS, code #6), and code #7 “other,” a catchall category which includes BPA-filled polycarbonate plastics, should not be used.
