The plastic in paper bowl customization generally belongs to plastic materials such as polyethylene (PE) or polypropylene (PP). These plastics have good heat and cold resistance and are suitable for the manufacture of food packaging containers. Polyethylene is a common plastic material, divided into high-density polyethylene (HDPE) and low-density polyethylene (LDPE). HDPE is often used to make strong food containers, while LDPE is often used in soft packaging materials. Polypropylene is another common food-grade plastic that has excellent high-temperature resistance, so it is often used in microwave food containers and hot food packaging. These plastic materials are widely used in food packaging because they meet hygienic standards and have good processability and recyclability.
