5.2 Box Production

Once the materials are prepared, they undergo several key processes:

• Injection Molding: Plastic is melted and injected into molds to create rigid boxes with complex shapes.
• Thermoforming: Sheets of plastic are heated and formed into shapes, typically used for flexible boxes.
• Blow Molding: Used for hollow plastic containers, this process involves inflating molten plastic within a mold.

5.3 Printing and Finishing

After the boxes are formed, they proceed to printing and finishing stages.

• Pre-Press Setup: Digital files are prepared and checked for accuracy before printing.
• Printing: Boxes are printed using screen or digital printing techniques, depending on the design requirements.
