What is a cardboard puncture strength testing machine?
In the packaging industry, the puncture strength of cardboard is one of the important indicators to measure its quality. The cardboard puncture strength testing machine is a device specially used to test the puncture resistance of cardboard, corrugated cardboard and other materials. This article will introduce in detail the definition, working principle, application scenarios and related data of the cardboard puncture strength testing machine.
1. Definition of cardboard puncture strength testing machine
The cardboard puncture strength tester is an instrument used to measure the puncture resistance of cardboard or corrugated cardboard when impacted by sharp objects. It provides a scientific basis for the quality assessment of packaging materials by simulating the impact conditions that may be encountered during actual transportation or use.
2. Working principle
The working principle of the cardboard puncture strength testing machine is to impact the cardboard sample with a certain speed and force through a puncture head of a specific shape, and record the energy required during the puncture process. This energy value is the puncture strength of the cardboard, usually expressed in joules (J) or kilograms of force·cm (kgf·cm).
3. Application scenarios
Cardboard puncture strength testing machines are widely used in packaging industry, quality inspection agencies, scientific research institutes and other fields. Its main application scenarios include:
| Application areas | Specific use |
