I. Introduction. In the fields of packaging, food, medicine and other fields, composite films are widely used because of their excellent moisture-proof, antibacterial and durability. These properties are highly dependent on the physical properties of the composite film, such as tensile strength, tear and deformation rate. In order to accurately evaluate these properties, the composite interlayer peel force tester plays a crucial role. The tester utilizes advanced testing principles and precise measurement techniques to provide researchers and engineers with a range of detailed data on the performance of composite membranes.
Second, the test principle.
At the heart of the composite film peel force tester is the clamping of the specimen between the two chucks of the film tensile strength tester fixture. Subsequently, the two chucks move relative to each other, exerting a tensile force on the specimen. A force sensor located on the moving chuck monitors and records changes in force during this process in real time, while a displacement sensor built into the machine tracks the displacement of the specimen.
3. Performance indicators.
By analyzing the changes in force values and displacements, the composite interlayer peel force tester is able to calculate the following key performance indicators:
Tensile strength: Indicates the maximum force that a material can withstand during stretching. This value is essential to evaluate the durability and stability of the laminate film in real-world applications.
Tear Strength: Reflects the material's ability to resist tearing. A high tear strength means that the composite film is not prone to rupture when subjected to external impact.
Deformation rate: Indicates the degree to which the shape of the material changes during the stress. A low deformation rate means that the composite film retains good stability when subjected to stretching.
Fourth, test accuracy and repeatability.
The composite interlayer peel force tester uses advanced sensing technology and control system to ensure high-precision test results. Its excellent repeatability allows users to test a large number of specimens in a short period of time, resulting in a reliable data set.
Fifth, the field of application.
Due to its powerful testing capabilities and wide range of applications, the composite film peel force tester has become an important tool in industries such as packaging materials, food packaging, and pharmaceutical packaging. By using this tester, manufacturers can better understand the performance of their products so they can optimize their production processes, improve product quality, and meet market demands.
VI. Conclusions. With its accurate and reliable testing capabilities, the composite film interlayer peel force tester provides strong support for the performance evaluation of composite films. Whether in research or industrial production, the instrument is an indispensable evaluation tool.
