The manufacturing process of corrugated box plastic for Okra generally includes the following steps:

• Material Selection and Preparation: Choose high-quality polypropylene (PP) or other food-grade plastic materials. The materials are carefully inspected and prepared, such as cleaning and drying if necessary.
• Sheet Extrusion: The selected plastic material is fed into an extruder. In the extruder, the material is melted and then formed into a continuous sheet through a specific die head under high temperature and pressure.
• Corrugation Forming: The flat sheet is then passed through a corrugating machine. This machine has rollers with specific patterns that press the sheet to create the characteristic corrugated shape. The depth and density of the corrugations can be adjusted according to different requirements.
• Cutting and Shaping: After corrugation, the large sheet is cut into the desired sizes for the boxes using cutting equipment. At this stage, accurate measurements and cuts are crucial to ensure the boxes fit together perfectly.
• Printing (if needed): If there are labeling or branding requirements, printing can be done at this stage. Using specialized plastic printing methods, patterns, logos, instructions, etc. can be printed on the surface of the corrugated plastic.
• Assembling and Finishing: The cut parts are assembled into boxes. This may involve gluing, welding, or other methods to join the various components. Finally, any rough edges are smoothed, and the boxes may undergo a quality check to ensure they meet the required standards.
