Luxury Lipstick Gift Box Case Study: EVA Insert Tolerance
A project-based case study showing the packaging requirement, the development decision, the quality-control focus and the reported project result.
Project Overview
| Box Structure |
Magnetic flip-top rigid box |
| Board |
1000gsm rigid board |
| Outer Paper |
157g paper |
| Insert |
EVA with red flocking |
| Finishing |
Full color, gold foil, scratch-resistant film |
| Main Concern |
Insert tolerance / lipstick movement |
| Improvement |
EVA tolerance ±0.3mm + 3 trial fittings |
| Result |
Smooth fit with no movement; 2 repeat orders |
The Challenge
The lipstick needed secure positioning without becoming difficult to insert or remove.
Structural & Material Solution
The EVA cavity was controlled to ±0.3mm and three trial fittings were completed before the final configuration was approved.
Key Improvement
The insert was developed as a functional component with measurable tolerance.
Quality Control
Checks covered EVA cavity dimensions, lipstick fit, movement, removal feel, box alignment, foil and film.
GooinPack's current packaging workflow places quality control after approved requirements, sampling and production. Current QC information covers materials, printing, dimensions, structure, finishing, insert fit, assembly and final inspection. View Packaging Quality Control.
