Production Process of Corn Starch-Based Rectangular Lunch Boxes:
 
1. Material Preparation:
        Corn Starch Extraction: Corn kernels are processed to extract starch, which is then purified and dried to obtain a fine powder.
        Additives: Other materials, such as plasticizers or natural fibers, may be added to enhance the properties of the corn starch.
2. Blending:
        Mixing: The corn starch is blended with polymers like polypropylene (PP) to create a composite material. This blending may involve physical or chemical methods to ensure uniform distribution.
        Modification: The blend can be modified with coupling agents to improve compatibility between the starch and PP, enhancing mechanical properties.
3. Processing Techniques:
        Extrusion: The blended material is fed into an extruder, where it is heated and melted. This process shapes the material into sheets or preforms suitable for molding.
        Injection Molding: The melted material is injected into molds to form the rectangular lunch boxes. This technique allows for precise shaping and efficient production.
4. Cooling and Solidifying:
        The molded lunch boxes are cooled to solidify the material, ensuring the final product retains its shape and structural integrity.
5. Quality Control:
        Finished products undergo quality checks to ensure they meet safety standards and performance criteria, such as durability and biodegradability.
6. Packaging:
        The lunch boxes are packaged for distribution, often using eco-friendly materials to align with the sustainable nature of the product.
7. Distribution:
        The packaged lunch boxes are then distributed to retailers, restaurants, and food service providers.
