Packaging Sampling Process Case Study for Premium Baijiu

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	Book-style magnetic rigid box
Board	1200gsm rigid board
Outer Paper	157g coated paper
Insert	Black flocked EVA
Finishing	Full color, scratch-resistant film, gold foil
Main Concern	Sample-to-mass-production consistency
Sampling	White sample → printed sample → finished sample
Control	Each stage signed/confirmed; standard sample retained
Result	Mass production matched approved sample; repeat order 3 months later

The Challenge

The buyer needed confidence that mass production would remain consistent with the approved sample.

Structural & Material Solution

Three sample stages were used: white sample, printed sample and finished sample. Each stage was confirmed and a standard sample was retained.

Key Improvement

The sampling process created clear approval checkpoints before mass production.

Quality Control

Checks included structure, dimensions, artwork, printing, film, gold foil, EVA fit and comparison with the approved sample.

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

Mass production matched approved sample; repeat order 3 months later
