Inclined Impact Tester and Cobb Sizing Tester Reliable Testing Solutions for Packaging and Paper Quality

In industries such as packaging, paper, and corrugated manufacturing, maintaining consistent quality is essential. Products must be protected during transportation, and materials must perform reliably under varying environmental conditions. To achieve this, manufacturers rely on specialized testing equipment that helps evaluate material strength, durability, and resistance.

Two important testing instruments widely used for this purpose are the Inclined Impact Tester and the Cobb Sizing Tester. Pacorr Testing Instruments offers both machines to support quality assurance, product development, and compliance with international standards. More information is available at pacorr.com.

Importance of Quality Testing in Packaging and Paper Industries

Packaging materials are exposed to multiple stresses during handling and transportation, including impacts, collisions, and movement on conveyors. If packaging fails, it can lead to damaged products, increased costs, and customer dissatisfaction. At the same time, paper and paperboard materials must resist moisture absorption to maintain strength, appearance, and performance.

Quality testing helps manufacturers:

  • Detect weaknesses in materials or design

  • Improve product durability and reliability

  • Reduce transportation damage and returns

  • Maintain consistent production quality

  • Meet ISO, ASTM, and TAPPI standards

The Inclined Impact Tester and Cobb Sizing Tester together provide a comprehensive solution for evaluating both mechanical strength and moisture resistance.

Inclined Impact Tester: Testing Packaging Strength During Transit

Overview

The Inclined Impact Tester is designed to assess the resistance of packaging to horizontal impacts. Such impacts commonly occur during loading, unloading, and transportation when packages collide with surfaces or other packages.

Pacorr’s Inclined Impact Tester simulates these real-life transportation conditions in a controlled testing environment, allowing manufacturers to evaluate packaging performance before products reach the market.

Working Principle

A test package is placed on a trolley mounted on an inclined track. When released, the trolley rolls downward due to gravity and strikes a rigid impact surface. The impact simulates collisions that may occur during transportation. After the test, the condition of the packaging and the product inside is evaluated.

The test setup allows adjustment of impact force and speed to simulate different transport scenarios, making the equipment suitable for a wide range of packaging types.

Applications and Benefits

  • Corrugated box and carton testing

  • Export and logistics packaging evaluation

  • Improved packaging design and strength

  • Reduced risk of product damage during transit

  • Compliance with international packaging standards

Pacorr’s Inclined Impact Tester is built with robust materials to ensure durability, smooth operation, and accurate test results.

Cobb Sizing Tester: Measuring Water Absorption in Paper Materials

Overview

The Cobb Sizing Tester is used to measure the amount of water absorbed by paper, paperboard, and corrugated materials over a specified period. Moisture resistance is a critical factor that affects paper strength, durability, and usability, especially in humid environments.

The result of this test is expressed as the Cobb value, which indicates the level of water absorption.

Working Principle

A paper sample is securely clamped under a metal test ring. A measured quantity of water is poured onto the surface of the sample and allowed to remain for a fixed duration. After the exposure time, excess water is removed, and the sample is weighed again. The increase in weight represents the amount of water absorbed.

Applications and Benefits

  • Paper and pulp manufacturing

  • Corrugated board production

  • Printing and packaging industries

  • Quality control and research laboratories

Key benefits include:

  • Better control over moisture resistance

  • Consistent paper quality

  • Accurate and repeatable results

  • Compliance with ISO, TAPPI, and ASTM standards

Pacorr’s Cobb Sizing Tester is designed for reliable performance and long-term laboratory use.

Melt Flow Index Tester – The Key to Reliable Plastic Manufacturing

Image
 When it comes to plastic production, the smallest change in raw material properties can lead to major setbacks. From uneven molding to poor product strength, the effects can be costly. That’s why many manufacturers rely on a quiet but powerful tool in their quality control arsenal: the Melt Flow Index Tester . It might look like just another machine on the lab bench, but its role is critical. The Melt Flow Index Tester helps manufacturers understand how their polymers behave when melted, making it easier to maintain consistency, reduce defects, and stay ahead of quality issues. Let’s explore how this device works and why every plastic processor should have one. What is a Melt Flow Index Tester? A Melt Flow Index Tester is used to measure the ease with which a thermoplastic polymer flows when heated. This test provides a value known as the Melt Flow Index (MFI), which is expressed in grams per 10 minutes. Essentially, it tells you how much of the polymer will pass through a di...

Understanding Salt Spray Chamber Why Corrosion Testing Matters for Quality and Durability

Image
  Salt spray chambers, also known as salt fog chambers, are essential tools in industrial and material science applications for assessing the durability of materials in corrosive environments. As corrosion remains a primary concern for many industries—from automotive to aerospace and electronics—salt spray testing provides a controlled, accelerated environment that reveals how materials or coatings react over time to salt exposure. This article explores the importance, applications, and benefits of salt spray chambers in ensuring product durability and reliability. 1. What is a Salt Spray Chamber? A salt spray chamber is a laboratory device designed to simulate a harsh, salt-laden environment. The Salt Spray Chamber creates a fine, consistent mist of salt solution, typically a mixture of water and sodium chloride, which settles on the test materials. This controlled environment can replicate years of natural exposure in a fraction of the time, providing essential insights int...
