Lab Testing Instrument Of Cardboard Resistance To Layer Separation Strength Paper Internal Adhesion Testing

The BGT-01 Internal Bond Tester is an essential tool for Paper Internal Adhesion Testing, specifically designed to measure the energy required to delaminate paper or cardboard layers. This sophisticated device evaluates how much energy is absorbed before the material fails in the Z-direction (thickness), an essential property for applications where paper and boards are subjected to sudden impacts, such as in printing, packaging, and conversion processes.

Why Perform Paper Internal Adhesion Testing?

In industries where paper or paperboard undergoes intense physical stress—such as printing, packaging, and other manufacturing processes—Paper Internal Adhesion Testing plays a crucial role. When materials are exposed to rapid impulses, shocks, or impacts, they can delaminate or suffer from structural defects like surface picks, blistering, or even internal splitting. These failures compromise the material's integrity and can significantly reduce the product’s quality, leading to wastage and product failures.

Understanding Paper Internal Adhesion Testing helps manufacturers avoid these problems by ensuring that paper and board materials can withstand the rigors of their specific applications.

Features of the BGT-01 Internal Bond Tester

The BGT-01 Internal Bond Tester is designed for precise and accurate Paper Internal Adhesion Testing, offering wide applicability across single-ply and multi-ply paper, including:

• Coated paper
• Synthetic polymer-laminated sheets
• Cardboard and packaging materials, such as case board, white board, grey board, and ivory board

The BGT-01 helps businesses ensure their paper and board materials meet industry standards and perform optimally during production.

Principle of Paper Internal Adhesion Testing

The BGT-01 Internal Bond Tester works by using a pendulum mechanism to apply a rapid impact to the test piece. A square sample of paper is attached to a flat metal anvil with double-sided adhesive tape. A precisely weighted pendulum strikes the sample, causing a delamination or rupture in the Z-direction. The energy required to split the paper is then measured to determine its internal bond strength.

By simulating real-world conditions where paper and board may be subjected to high-velocity impacts, Paper Internal Adhesion Testing ensures that materials will perform as expected during the stresses of printing or conversion processes.

Importance of Paper Internal Adhesion Testing in Different Industries

1. Packaging Industry: Ensures that packaging materials maintain their structural integrity during shipping and handling. Paper Internal Adhesion Testing helps verify that multi-ply boards will not delaminate under pressure, preserving the product's quality.

2. Printing Industry: High-speed printing equipment subjects paper to rapid mechanical stress. Testing the internal bond strength ensures that the paper won't blister or delaminate during the printing process, which could otherwise cause costly delays and print quality issues.

3. Pharmaceutical Industry: Testing ensures that pharmaceutical packaging can withstand external forces during shipping and handling without compromising the integrity of the package, thus protecting the contents.

4. Food and Beverage Industry: Packaging materials are critical in preserving product freshness and preventing contamination. Paper Internal Adhesion Testing ensures packaging durability, particularly for multi-layered materials used in food and beverage cartons.
