Technical Principles of Corn Starch-Based Rectangular Lunch Boxes:

1. Material Composition:

• Corn Starch-Based Material: Derived from the starch extracted from corn, this biopolymer is biodegradable and compostable, making it an eco-friendly alternative to conventional plastics.

• Polypropylene (PP): A widely used thermoplastic known for its strength, heat resistance, and chemical stability. It enhances the mechanical properties of the lunch box.

2. Blending Process:

• Compatibility: The corn starch and PP are blended to create a composite material that utilizes the strengths of both components. This involves physical or chemical blending techniques to ensure uniform distribution of the starch within the PP matrix.

• Modification: The properties of the blended material can be further enhanced through processes such as plasticization (adding plasticizers) or coupling agents to improve the interaction between the two polymers.

3. Molding Techniques:

• Injection Molding: The blended material is processed using injection molding, where it is melted and injected into molds to form rectangular lunch boxes. This method allows for precise shaping and efficient production.

• Extrusion: Alternatively, extrusion can be used to create sheets or preforms that are then shaped into lunch boxes.

4. Biodegradability:

• The corn starch component allows the lunch boxes to decompose naturally in composting environments, facilitated by microbial action. This characteristic is crucial for reducing plastic waste.

5. Heat Resistance:

• The addition of PP provides enhanced heat resistance, allowing the lunch boxes to hold hot foods without deforming, making them suitable for a variety of meal options.

6. Barrier Properties:

• The composite material can exhibit improved barrier properties against moisture and gases, helping to maintain food freshness and quality.

7. Applications:

• These lunch boxes are suitable for various food service applications, including restaurants, catering, and meal delivery services, offering a sustainable option for packaging.
