Case Study: Sustainable Tablet Packaging Box Designed for Mass Production
Project Background
When we first received the tablet mock-up from the client’s headquarters, our engineering team immediately noticed a potential risk.
The tablet measured approximately 261 × 178 × 6 mm, and the side buttons protruded slightly from the body. During transportation, these buttons could easily be damaged by compression or friction.
Traditionally, EVA foam inserts would solve this problem. However, the client required a paper-based structure with minimal plastic use, which meant we needed a different solution.
At the same time, the electronics packaging box had to remain compact and suitable for large-scale automated production.
Designing Protection Without Foam
Instead of using foam inserts, we designed a paper protective border inside the base box.
Our engineer Mr. Zhang proposed building a die-cut frame around the tablet using:
- 350gsm C1S paperboard
- Matte lamination
- Precision die-cut clearance for side buttons
This paper border holds the tablet in position while leaving space around the buttons so they are never under pressure.
After structural testing, the packaging passed over 100 drop tests, confirming that the buttons were fully protected during transport.
This approach replaced foam inserts entirely while maintaining reliable protection.
Compact Lid and Base Structure
We designed the packaging as a 2-piece lid and base rigid box.
The inner dimensions were set to 265 × 182 mm, providing a close fit while keeping enough tolerance for assembly.
This structure provides:
Good compression strength during shipping
Stable stacking
Controlled opening resistance
When the lid is lifted, the air resistance creates a slight suction effect and soft “pop” sound, which is typical for well-made electronics packaging.
Solving the Accessory Movement Problem
During prototyping we encountered a practical problem.
Compared to the tablet size, the charging cable and power adapter were relatively small, leaving empty space inside the paper tray.
When we shook the box during testing, the cable moved around and produced noise. This was not acceptable for a retail electronics product and also reduced protection.
Mr. Zhang redesigned the accessory packaging by adding an internal frame structure inside a reverse tuck carton.
This allowed the charging cable to be locked into position so it could not move during transportation.
An important advantage was that our automatic folder-gluer can produce this inner-frame carton, so the additional structure increased cost only slightly.
This solution improved both protection and production efficiency.
Paper Tray Structure
All accessories were placed underneath the tablet:
- Charging cable
- Power adapter
- User manual
We designed a folded paper tray made from 350gsm C1S to:
- Support the tablet
- Hold accessories in position
- Provide cushioning
- Simplify assembly
Using the same material for borders, trays, and cartons simplified purchasing and reduced production costs.
All components are recyclable paperboard.
Protective Border Structure Test
Instead of using foam inserts, we designed a paper protective border inside the base box.
Our engineer Mr. Zhang proposed building a die-cut frame around the tablet using:
- 350gsm C1S paperboard
- Matte lamination
- Precision die-cut clearance for side buttons
This paper border holds the tablet in position while leaving space around the buttons so they are never under pressure.
After structural testing, the packaging passed over 100 drop tests, confirming that the buttons were fully protected during transport.
This approach replaced foam inserts entirely while maintaining reliable protection.
Surface Finish Testing
We tested three different matte laminations before selecting the final finish.
Under strong lighting conditions, some matte films still produced visible reflections. We rejected those options.
The selected film has:
- Low reflectivity under strong light
- A slightly suede-like touch
- Stable adhesion during embossing
After lamination, we applied an overall embossing texture to the printed paper.
Tablet users often pay attention to the tactile feel during unboxing, so surface touch was an important detail in this project.
Prototype Development
Before mass production, we produced 50 fully die-cut white samples using real tooling.
These samples were sent to:
- The client’s design department
- The product assembly factory
Several structural adjustments were made based on testing feedback before final approval.
Mass Production
The first production order was 50,000 sets.
The rigid boxes were produced on our automatic rigid box assembly lines.
Although this is a full-wrap rigid box structure, our automated lines maintained stable production speed and consistent dimensions.
Production and delivery were completed within 20 days.
Quality Control During Production
Printed sheets go through multiple processes, so extra quantities were prepared for machine setup.
Before entering automatic assembly, two QC inspectors checked the printed sheets one by one and removed any defects.
During production:
- Two QC staff remained on the assembly line
- Dimensions and surface finish were checked continuously
- Any issue was reported immediately to the production supervisor for machine adjustment
This ensured consistent quality across all units.
Results
The final packaging achieved:
- Fully paper-based protection
- Reliable button protection
- Stable accessory positioning
- Compact structure
- Efficient automated production
The product has since been launched successfully, and the packaging design has been maintained in continued production.
