The burger box is 100% made of sugarcane bagasse, so it can bio-degrade into fertilizer within 90 days to nourish other plants, reduce foot carbon, and eliminate white pollution. At the same time, the hamburger sandwich box doesn't contain any toxic materials verified by FDA, such as wax lining, artificial coating, chlorine and PFAS, etc., to ensure food contact safety. It is worth mentioning that, unlike foam and thin paper, the take out box is heavy-duty to prevent food from pouring out during transportation. The clever tab-slot design and excellent oil resistance make it easy for you to pack food without worrying about oil or moisture leakage. After packaging the left-over home, you can confidently use the food container to refrigerate it in the freezer or reheat it in the microwave without ifs or buts, which can withstand up to 200 degrees Fahrenheit.
