Bending Strength Testing Machine for Corner Protectors of Packaging
Cartons and Boxes
1. Overview
The Paper Angle Protector Bending Strength Tester is a testing
instrument used to measure the compressive strength of products.
It is mainly applicable to L-type paper angle protectors, U-type
paper angle protectors, bent paper angle protectors, waterproof
paper angle protectors, wrapped paper angle protectors,
special-shaped paper angle protectors, etc.
It is an ideal testing equipment for paper angle protector
manufacturers, quality inspection institutions and other related
departments.
Standards implemented: ISO 2872, ISO 2874, GB 4857.4

What is the working principle of a corner bend strength tester for
packaging cartons?The L-shaped paper corner protector sample is placed on a bending
support with a spacing of 200mm. A 90° rigid loading head is
pressed down on the middle of the sample at a uniform speed of
(100±10)mm/min. The sensor collects the force value in real time
and records the maximum bending force when the sample is crushed,
thereby determining the bending strength of the corner protector. |  |
