1. Grease resistance:The bag is made with a grease-resistant coating or oil-resistant material, effectively preventing oil from burgers, fries, and other foods from seeping through, keeping hands and clothing clean.
2. Heat retention and breathability:The paper material allows some airflow, preventing condensation that would make burger buns soggy, while still helping to maintain food temperature.
3. Easy eating:The open-top design allows customers to eat directly from the bag without additional utensils, making it suitable for dine-in, takeout, or delivery.
4. Brand promotion:The bag surface can be printed with restaurant logos, slogans, or promotional messages, increasing brand visibility, while the kraft paper material conveys a natural and fast-food brand image.
