Quang Minh Packaging JSC Laboratory – The Foundation of Product Quality Assurance
The LAB facility at Quang Minh Packaging JSC is a dedicated quality control center equipped with bursting strength testers, edge crush testers (ECT), ring crush testers (RCT), and box compression testers (BCT), ensuring carton durability, structural integrity, and compliance with international standards.
Introduction to the LAB Facility
At Quang Minh Packaging JSC, quality is regarded as the heart of manufacturing.
To ensure every carton packaging product meets the highest technical standards, the company has established a dedicated Quality Control LAB — a specialized testing facility where inspection, measurement, and analysis activities are conducted at every stage of production.
The LAB is equipped with advanced testing instruments compliant with international standards, enabling precise evaluation of strength, load-bearing capacity, structural stability, and safety of carton boxes before shipment.
The Role of the Quality Control LAB in Carton Packaging Production
The LAB serves as the “quality assurance center”, ensuring that:
– Every production batch achieves high precision and consistency.
– Packaging meets real-world requirements for load bearing, transportation, and warehousing.
– Products comply with both domestic and international standards.
Closed-Loop Quality Control Process at Quang Minh Packaging JSC The LAB operates continuously within Quang Minh Packaging JSC’s fully integrated production system, structured around three key stages:
Incoming Material Inspection
In-Process Quality Control
Finished Goods Inspection
Advanced Testing Equipment at the Quality Control LAB
Bursting Strength Tester – Evaluating Carton Board Rupture Resistance
The Bursting Strength Tester is used to evaluate the resistance of corrugated board to cracking, bursting, or tearing under applied pressure.
Bursting strength values help determine the quality and resilience of the paper layers, ensuring carton boxes can withstand impact during transportation without damage.
Edge Crush & Ring Crush Testers – Structural Strength Assessment
– Edge Crush Test (ECT): Measures the edgewise compressive strength of corrugated board fluting — a key factor determining the rigidity of corrugated sheets.
– Ring Crush Test (RCT): Evaluates the flat crush resistance of individual liner layers in multi-ply construction, ensuring stable bonding between paper layers.
These two tests enable Quang Minh Packaging JSC to determine the stiffness, load-bearing capacity, and overall quality of corrugated board.
Box Compression Tester – Measuring Load-Bearing and Stacking Strength
The Box Compression Tester (BCT) measures the overall compressive strength of carton boxes, evaluating their load-bearing capacity when stacked in warehouses or containers.
Test results guide adjustments to flute profiles, paper grades, and adhesive types to ensure boxes remain free from deformation, collapse, or breakage during transit.
Testing – Analysis – Quality Assurance Process
Routine Incoming Raw Material Inspection
Every batch of paper, adhesive, and printing ink is tested at the LAB before entering production, verifying that moisture content, caliper thickness, and bonding strength meet required standards.
In-Process Quality Control
LAB engineers regularly collect random samples from the production line to measure compression strength, bursting strength, and adhesive bond quality — ensuring batch-to-batch consistency.
Finished Product Evaluation Before Shipment
Prior to dispatch, products are tested for box compression strength, load-bearing capacity, and surface flatness to ensure uniform quality that meets export standards.
Advantages of Quang Minh Packaging JSC’s Testing System
High Precision – International Standards Compliance
All LAB equipment is imported and periodically calibrated, complying with ISO, TAPPI, ASTM, and JIS testing standards.
Consistent Quality – Enhanced Brand Credibility
Through rigorous testing protocols, Quang Minh Packaging JSC maintains consistent quality across production batches, giving customers complete confidence in product durability and precision.
Cost Optimization and Production Risk Reduction
Precise testing from the incoming material stage prevents production defects, reduces raw material waste, and optimizes operational costs — delivering high production efficiency and sustainable value.
