Recently, Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. and Qilu University of Technology jointly established a teaching and research joint laboratory to promote effective cooperation between high-level industry, academia, and research, enhance the company's independent innovation capabilities and core competitiveness, and overcome core technological challenges. In addition, Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. provides comprehensive quality solutions for pharmaceutical composite film bags in the pharmaceutical field.

YBB00132020-2015 "General Rules for Medicinal Composite Films and Bags" provides a detailed introduction to the peel strength of the inner and second inner layers of medicinal composite film bags. This article uses the YYB-03 pharmaceutical packaging tearing force tester from Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. to provide a detailed introduction to the solution for the peeling force of the inner and second inner layers of pharmaceutical composite film bags.

Equipment Introduction:

The peel strength tester for the inner and second inner layers of pharmaceutical composite film bags, also known as the pharmaceutical packaging tear strength tester YYB-03, meets the requirements of the new GMP version and is equipped with a large LCD display screen and printing function.

Experimental principle;

The sample is clamped between two clamping heads of the fixture, and the two clamping heads move relative to each other. The force value sensor located on the moving clamping head and the displacement sensor built into the machine are used to collect the changes in force and displacement during the test process, thereby calculating the peel strength of the sample.

Technical Specifications

Measurement * Level 5

Test speed 1-500mm/min stepless speed regulation

Test width 30mm

Displacement error ± 0.5%

Execute standard YBB00132002

Product model yyb-03

Standard configuration: Inner and sub inner layer peel strength tester host, micro printer

Standard regulations: Take an appropriate amount of film and bag, and measure the peel strength according to the YBB00102003-2015 peel strength measurement method. The average values of longitudinal and transverse peel strength should comply with the provisions of Table 3.

Experimental method:

(1) Set parameters such as heat sealing temperature, heat sealing pressure, heat sealing time, sample name, and test width on the control software of the device, and select test method B.

(2) Cut 5 samples with a width of 15 mm and a length of at least 25 mm along the longitudinal direction of the sample to be tested.

(3) After the device reaches the set heat sealing temperature, take one of the samples and clamp both ends of the sample in two sample fixtures, so that the sample passes around the sample dragging mechanism and the heat sealing surface contacts the dragging mechanism.

(4) Pull the drag mechanism to make the hot sealing surface of the sample contact each other and enter between the heat sealing knives. Step on the foot switch, and the heat sealing knife will heat seal the sample. At the same time, release the drag mechanism. The equipment will heat seal the sample according to the set heat sealing parameters, and the heat sealing knife will automatically separate. After a delay of 0.1 seconds, the fixture will retract to the initial state of the thermal adhesion strength test within 0.1 seconds. Then, pull the heat sealing part at a fixture separation speed of 200 mm/s, and test its thermal adhesion strength through the force sensor configured on the fixture.

(5) Test the thermal adhesive strength of the remaining 4 samples in sequence by following the steps of clamping the sample, moving the drag mechanism, stepping on the foot switch, and releasing the drag mechanism.

The peeling force between the inner and second inner layers of pharmaceutical composite film bags is an experimental method for detecting the firmness index of packaging materials, and is an important detection index that affects the quality of pharmaceutical composite film bags. The pharmaceutical packaging tearing force tester of Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. has a simple testing process, high degree of equipment automation, simple operation, and accurate and reliable test results.
