Yes, stretch film (also known as cling wrap) often contains phthalates, which boost its elasticity, and bisphenol A (BPA). Both are endocrine disruptors that interfere with reproductive hormones. This poses real concerns for children and pregnant women. Studies link low-dose exposure to risks like sterility, birth defects, cancers, and obesity.
The risk drops significantly if the film avoids direct food contact. The biggest issue? Cooking or reheating food in it. Heat destabilizes phthalates and BPA, allowing them to migrate into food more easily. Storing a rice salad in the fridge? That's low-risk and generally safe.
