What is a packaging bag tensile testing machine?
In today's industrial production and quality control fields, packaging bag tensile testing machines, as an important testing equipment, have received widespread attention. This article will introduce in detail the definition, working principle, application scenarios and recent hot topics of the packaging bag tensile testing machine to help readers fully understand this equipment.
1. Definition of packaging bag tensile testing machine

The packaging bag tensile testing machine is a professional equipment used to test the tensile strength, tearing performance, elongation at break and other mechanical properties of packaging bag materials. It evaluates the durability and safety of packaging bags by simulating the tension they experience during actual use, ensuring that packaging materials meet industry standards and customer needs.
2. Working principle
The working principle of the packaging bag tensile testing machine is based on mechanical sensors and control systems. The equipment fixes the packaging bag sample through the clamp and applies gradually increasing pulling force until the sample breaks or reaches a preset condition. During the test, the equipment will record the tensile force value and deformation amount in real time, and generate a detailed test report.
| Test parameters | Description |
|---|---|
| Maximum pulling force | The maximum tensile force the sample can withstand before breaking |
| Elongation at break | The ratio of the elongation at break to the original length of the sample |
| Tear strength | The force required to tear the sample |
3. Application scenarios
Packaging bag tensile testing machines are widely used in the following fields:
| Industry | Application |
|---|---|
| food packaging | Testing the tensile strength and sealing performance of food bags |
