GRT-1 Rubbing Test Instrument

GRT-1 Rubbing Tester

Product Name: Packaging Bag Rubbing Test Machine

Scope of Application

Suitable for testing the rubbing resistance of various films, composite films, coated films, and other materials, as well as the rubbing resistance of flexible barrier films in sterile medical device packaging. It can simulate behaviors such as rubbing and compression damage that films may experience during production, processing, transportation, and other processes. After the rubbing test, the material's rubbing resistance is determined by detecting changes in the number of pinholes or barrier performance before and after the test, providing quantitative data for packaging design and practical applications.

Rubbing Test Instrument: The rubbing test is a method used to evaluate the durability and performance changes of plastic films, thin sheets, composite films, and coated films when subjected to mechanical forces (such as rubbing). This test is particularly important for packaging materials, as they may endure various physical stresses during production, transportation, and use. By simulating mechanical stresses under actual usage conditions, the material's durability, tear resistance, and other related properties can be better understood.
