Box Design
Design the box, including dimensions, flaps, and locking mechanisms, using packaging design software.

Carton Die Cutting and Scoring

2.Create score lines on the paper to ensure precise folds. This helps the paperboard fold neatly without tearing.

Carton Printing
Prepare graphics, logos, and any necessary branding text.
Print the design onto the chosen paperboard material using techniques such as offset, digital, or flexographic printing.

Carton Assembly
Fold the bottom flap over and tuck the locking flap into place, securing it tightly to create a stable base.

Carton Quality Inspection
Inspect the quality of the finished boxes to ensure they meet specifications for size, structural integrity, and print quality.

Demonstrate the strictness of quality inspection

Structural Integrity:
Test the strength of the box after assembly.
Inspect the card material for any warping or bending.

Locking Mechanism:
Make sure the locking mechanism on the bottom is secure with no gaps.
Test how easily the box closes and whether it stays closed under stress (such as weight or pressure).

Load Capacity:

Load test by applying weight to the box to determine how much weight it can support before failure.
Observe any deformation or failure points in the box material.

Durability:

Subject the box to different environmental conditions (e.g. humidity, temperature changes) to assess any possible deterioration over time.

Printing Quality:

If the box has graphics or labels printed on it, assess the quality of the print and ensure it does not smudge or wash off.
