In packaging and paper manufacturing, quality testing is essential to ensure product safety, durability, and customer satisfaction. Packaging must protect goods during transportation, while paper and board materials must resist moisture to maintain strength and performance. To meet these requirements, manufacturers rely on accurate laboratory testing equipment.
Two widely used instruments for this purpose are the Inclined Impact Tester and the Cobb Sizing Tester. Pacorr Testing Instruments provides both solutions to help industries maintain consistent quality and comply with international testing standards. More details are available at pacorr.com.
Importance of Quality Testing in Packaging and Paper
During handling and transportation, packaging materials experience impacts, vibration, and movement. Weak packaging can result in damaged products, increased costs, and loss of customer trust. Similarly, paper and corrugated materials that absorb excessive moisture lose strength and become unsuitable for packaging or printing applications.
Quality testing helps manufacturers:
Identify material weaknesses
Improve packaging and paper performance
Reduce transit damage and product returns
Maintain consistent manufacturing standards
Meet ISO, ASTM, and TAPPI requirements
The Inclined Impact Tester and Cobb Sizing Tester together address these critical quality concerns.
Inclined Impact Tester: Evaluating Packaging Durability
Overview
The Inclined Impact Tester is used to test the resistance of packaging to horizontal impacts. These impacts commonly occur during loading, unloading, and transportation when packages collide with surfaces or other packages.
Pacorr’s Inclined Impact Tester simulates such real-life conditions in a controlled environment, allowing manufacturers to evaluate packaging strength before shipment.
Working Principle
A test package is placed on a trolley mounted on an inclined rail. When released, the trolley moves downward due to gravity and strikes a rigid impact surface. The effect of this impact on the package and its contents is then examined.
Test parameters such as incline angle and impact force can be adjusted to simulate different transportation conditions.
Applications and Benefits
Corrugated box and carton testing
Export and logistics packaging evaluation
Improved packaging design
Reduced product damage during transit
Compliance with international packaging standards
Pacorr’s Inclined Impact Tester is built for durability, accuracy, and smooth operation.
Cobb Sizing Tester: Measuring Water Absorption in Paper
Overview
The Cobb Sizing Tester is used to determine the amount of water absorbed by paper, paperboard, and corrugated materials over a specific time period. Moisture resistance is a key factor affecting paper strength, appearance, and performance.
The result of the test is expressed as the Cobb value, measured in grams per square meter.
Working Principle
A paper sample is clamped securely under a metal ring. A measured quantity of water is poured onto the surface and allowed to remain for a fixed duration. After removing excess water, the sample is weighed again. The increase in weight indicates the level of water absorption.
Applications and Benefits
Paper and pulp manufacturing
Corrugated board production
Printing and packaging industries
Quality control laboratories
Benefits include:
Improved moisture resistance control
Consistent paper quality
Accurate and repeatable results
Compliance with ISO, TAPPI, and ASTM standards
Pacorr’s Cobb Sizing Tester is designed for long-term laboratory use with reliable performance.
