Test Method for Rubbing Resistance of Soft Barrier Membrane

《YY-T 0681.12-2014Test method for packaging of sterile medical devices 第12part Soft Barrier Membrane Rubbing Resistance

The experimental method in the standard uses pinhole formation as the evaluation criterion for determining whether there is damage, or other gas permeability experiments can be used instead of pinhole experiments.

Test significance

Used to measure the resistance of soft packaging film materials to rubbing and forming pinholes. This experiment can also simulate the rolling, folding, and other behaviors of the film during production, processing, and transportation. By comparing the changes in the number of pinholes, barrier properties, or other physical properties of the sample before and after rolling, the anti rolling performance of the sample can be judged, providing technical support for the practical application of packaging film materials.

test method

The standard specifies five experimental conditions, summarized as follows

conditionA: Full kneading1h(i.e2700Next cycle)

conditionB: Full kneading20min(i.e900Next cycle)

conditionC: Full kneading6min(i.e270Next cycle)

conditionD: Full kneading20Next cycle

conditionBPartial Rubbing20Next cycle

Rubbing TesterGFT-01adoptPLCIndustrial control program coordination7Inch human-machine interaction system with built-in standard specifications5In this experimental mode, users can directly touch the screen to select the experimental program and retrieve the testing conditions.

After clicking on the corresponding experimental mode, the instrument will automatically conduct experiments and stop automatically after the experiment is completed.

Pinhole counting

Remove the soft barrier sample from the rubbing tester and mark it in the center of the white paper150mm×200mmThe region,150mmIt is the axial dimension of the testing instrument.

Stick the sample onto white paper with tape, brush the dyed turpentine solution onto the sample with a brush, brush multiple times, and leave it on1minThen use absorbent toilet paper to wipe off the dyed turpentine, remove the sample from the paper, and count the pinhole penetration points on the paper.

The above can meet the testing requirements for the anti rubbing properties of soft barrier films in the market.
