Yes, sandwich bags are suitable for both cold and warm foods, provided they are not used in high-heat environments like ovens or microwaves. Most standard sandwich bags are made from LDPE or HDPE, which tolerate warm temperatures and help retain moisture.
They are commonly used to hold bakery goods, sandwiches, fruits, and snacks directly from prep lines into refrigerated displays or warming cabinets. As long as the food is not piping hot or oily, sandwich bags provide effective containment without compromising food quality.
For best results, use thicker bags for slightly warm items, and always check manufacturer guidelines to avoid stretching or melting under heat.
