Ply Bond Tester (ZDT Type)

This is an equipment to measure the internal fiber bond strength of Paper Board by measuring the force required to separate the layers / plies.

A high Ply Bond value indicates a well-compacted, strong board which will make high quality Paper Cores and Corrugated Cartons.

Suitable for : Paper Boards.

Confirms to : TAPPI T-541
