The material of takeout packaging boxes

Among the materials used for takeout packaging boxes, those made of PP (polypropylene) are characterized by their high temperature resistance. Packaging boxes made of PET (polyethylene terephthalate) and PS (polystyrene) pose significant health risks due to the toxic substances they contain, which can leach out at high temperatures. Items labeled with PET and PS should not be used frequently. The material of takeout packaging boxes is essential for takeout food delivery services. With the rise of such services in recent years, the demand for takeout packaging boxes and bags has increased significantly, and there are many different styles available. Most takeout food packaging containers on the market are made of plastic and are labeled with numbers. Different materials are represented by different numbers, generally ranging from 01 to 07. 01 indicates polyethylene terephthalate (PET), which is commonly used in mineral water bottles and carbonated beverage bottles, and has a heat resistance temperature of 70°C.

There are many factors in the material of takeout packaging boxes that affect the compatibility between food quality and packaging quality, such as how much can be packed, how much can be transported, whether the heat and/or liquid of the food can be maintained, and whether waste and spoilage can be prevented. For example, a cardboard box without proper insulation may not be suitable for transporting food with liquid sauce. Different materials used for takeout packaging boxes have different impacts on the environment. Comparing disposable takeout packaging made from different materials, multiple studies have shown that PS, XPS, and paper packaging tend to have better environmental performance than other packaging alternatives (PET, PLA, PP, aluminum).
