Product Application
This is an internationally‑used Mullen‑type instrument, widely applied for packaging materials. It is mainly used to measure puncture strength of various paperboards as well as single‑ply and multi‑ply corrugated paperboards. It can also test puncture‑resistance performance of non‑paper materials such as silk and cotton fabrics. After loading specimens, the instrument can realize automatic detection, automatic test, automatic hydraulic return, automatic calculation, test data storage and printing. Test results and processed data can be digitally displayed and automatically printed.
