[0002] An instant noodle bowl lid refers to a lid used to cover the top of an instant noodle bowl to keep the food warm, prevent the food from splashing or spilling, and maintain food hygiene. Instant noodle bowl lids are usually made of plastic, and sometimes paper or other materials are also used. The amount of plastic used in instant noodle bowl lids depends on various factors, including but not limited to the design, size, material type, and production process of the lid. Instant noodle bowl lids are usually made of multiple layers, and the plastic materials used include polypropylene (PP), polyethylene (PE), polyester (PET), etc. The selection of these materials is based on factors such as their thermal stability, transparency, and cost. With the increasing awareness of environmental protection, more and more manufacturers are gradually reducing the use of plastic materials, thereby increasing the plastic proportion of instant noodle bowl lid products. However, with the existing process methods for producing instant noodle bowl lids, the plastic proportion is still relatively high. Summary of the Utility Model
