What is The Test for Bond Strength?

In the packaging, paper, and composites industries, bond strength is an important indicator of a material's interlayer bonding performance. Whether it is paperboard, aluminum foil composite packaging material, or film composite material, its internal bond strength directly affects the durability and quality of the product. Paper interlayer bond tester (also known as paper and cardboard interlayer peel strength tester), is a specialized equipment for measuring the bond strength of paper interlayer. The following is a detailed introduction about it:

Internal Bond Strength Tester GT-N25 is a precision instrument specialized in measuring the internal bond strength of paper and cardboard (between paper plies, internal bond strength of paper) and composite materials. Typical test materials include:

• Paper materials: cigarette paper, whiteboard, kraft paper, boxboard, etc.

• Composite materials: aluminum foil composite packaging materials, film composites, and other sheet materials.

By accurately measuring the material's Z-direction resistance (delamination resistance in thickness direction), the ply bond tester ensures that the product will not be delaminated or cracked during transportation, storage and use, and is widely used in the fields of papermaking, packaging, printing, and quality inspection laboratories.

Standards

• GB/T 26203, ASTM T569 pm-00, DIN ISO 16260, TAPPI-UM403, TAPPI T833pm-94, TAPPI T569pm-00

The combination of double-sided tape, sample, and double-sided tape forms a sandwich structure, which is pressed between a metal anvil and an aluminum block The inner surface of the upper part of the aluminum block is hit with a pendulum, causing the aluminum block to flip and damage the sample in the Z direction. Calculate the energy absorbed by the sample during delamination by measuring the position of the swing, expressed in J/m2.
