Rigid Box Board Thickness Engineering Case Study

A project-based case study showing the packaging requirement, the development decision, the quality-control focus and the reported project result.

Project Overview

Application	Premium supplement packaging
Box Structure	Two-piece rigid box
Initial Board	1000gsm
Comparison	1200gsm and 1500gsm
Outer Paper	157g coated paper
Insert	Black flocked EVA
Finishing	Full color, scratch-resistant film, embossing
Main Concern	Box felt too soft
Result	1200gsm selected; repeat order 3 months later

The Challenge

The initial 1000gsm specification did not provide the desired rigidity.

Structural & Material Solution

The project compared 1000gsm, 1200gsm and 1500gsm under the same general packaging concept. The buyer selected 1200gsm as the preferred balance.

Key Improvement

The project demonstrates why board thickness should be selected against structure and application rather than by choosing the thickest option automatically.

Quality Control

Checks covered rigidity, box feel, dimensions, wrapping, insert fit, printing, embossing and scratch-resistant 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.

Project Result

1200gsm selected; repeat order 3 months later
