PP plastic fast food box becomes mainstream

Disposable plastic fast food box is a kind of apparatus made of resin or other thermoplastic materials by high temperature hot melt plastic injection molding technology. In terms of application, disposable plastic fast food boxes can be divided into lunch boxes, fresh cut and Pickled fruit boxes, semi-finished food boxes and others. In terms of raw materials, disposable plastic fast food boxes are mainly classified into PP (polypropylene) fast food boxes, PS (polystyrene) fast food boxes and EPS (expanded polystyrene) fast food boxes. Compared with the other two kinds of raw materials, PP plastic fast food box has high heat resistance and is the only one that can be heated in microwave oven. PP plastic fast food box is suitable for almost all kinds of food and beverage because of its high chemical stability and good corrosion resistance. The degradation time of PP, PS and EPS varied depending on the environmental conditions. If they are all filled in the same landfill, PP and PS plastic fast food boxes will take about 20 to 30 years and 40 to 50 years to degrade, respectively, while EPS plastic fast food boxes will take hundreds of years to degrade. However, exposure to certain elements such as sunlight, moisture and air will accelerate the degradation. At the same time, as the Chinese government is actively investing in environmental protection, PP plastic fast food boxes which are easy to recycle and can be decomposed by adding degradable materials (such as starch, photosensitizer and biological inhibitor) into the production of fast food boxes have become the mainstream of China's disposable plastic fast food box industry.
