Is it safe to buy bread in a plastic bag?
Based on 1 peer-reviewed studykitchen
Verdict: Use Caution
Relatively low risk. Bread is relatively dry and cool. The exposure is small.
What's actually in it
Sandwich bread bags are LDPE (polyethylene). Bread is low-moisture at room temperature. Migration is minimal compared to fatty or hot foods.
What the research says
A 2025 study identified the biggest phthalate sources as fatty warm foods in plastic. Bread is not on that list.
For sourdough lovers, transfer bread to a cotton bag or bread box for better texture. The plastic bag is acceptable but not ideal.
