In modern packaging industry, the heat sealing performance of packaging bags is one of the important indicators to measure their quality and reliability. In order to ensure the integrity of packaging bags during storage, transportation, and use, the RFY-05 packaging bag heat sealing performance tester from Jinan Sanquan Zhongshi has emerged. This article will provide a detailed introduction to the testing principle of the heat sealing tester and its application in materials such as films, medicinal aluminum foils, and PVC hard sheets.

Test Principle

The RFY-05 packaging bag heat sealing performance tester of Jinan Sanquan Zhongshi adopts the hot pressing sealing method for testing. The basic principle is to place the sample to be sealed between the upper and lower hot heads, and under the pre-set temperature, pressure, and time conditions, the sample is melted and bonded at the heat sealing interface through the heating and pressure of the hot head, thus completing the sealing process. During this process, temperature, pressure, and time are key control parameters, and their precise setting and control are crucial for ensuring the heat sealing effect.

Temperature control: The packaging bag heat sealing performance tester adopts PID temperature control technology, which can accurately and quickly reach and maintain the set temperature. PID temperature control technology continuously monitors and adjusts the heating power to maintain a constant temperature of the hot head, ensuring consistent heat sealing conditions for each test.

Pressure control: To ensure fast and accurate pressure setting, the heat sealing clip slowly approaches and seals adjacent samples. The pressure control system can ensure the stability and accuracy of pressure during the testing process, avoiding unstable heat seal quality caused by pressure fluctuations.

Time control: The setting of heat sealing time can be adjusted as needed, and it is accurate to 0.01 seconds. The user controls the heat sealing time of the sample by pressing the foot switch. When the foot switch is pressed down, the sample begins to heat up and timer; After releasing the foot switch, the upper and lower heat sealing knives separate, and the heat sealing process ends.

Scope of application

The RFY-05 packaging bag heat sealing performance tester from Jinan Sanquan Zhongshi is mainly suitable for testing the heat sealing performance of materials such as films, composite films, PVC hard sheets, and medicinal aluminum foils. These materials have a wide range of applications in the packaging industry, and their heat sealing performance directly affects the sealing, stability, and safety of packaging products.

Film: Used for accurate measurement of parameters such as heat sealing temperature, heat sealing time, and heat sealing pressure of packaging materials such as films and composite films. The optimization of these parameters helps to improve the heat sealing strength and sealing performance of packaging materials.

Medicinal aluminum foil: Test the heat sealing strength between medicinal aluminum foil and aluminum foil, as well as between aluminum foil and hard sheet. In drug packaging, the heat sealing strength of medicinal aluminum foil is directly related to the moisture resistance, oxidation resistance, and pollution resistance of the drug.

PVC hard sheet: Test the heat sealing strength between PVC hard sheet and medicinal aluminum foil. PVC hard sheets have a wide range of applications in fields such as pharmaceuticals and food due to their excellent transparency and mechanical properties. Through the testing of the packaging bag heat sealing performance tester, it can be ensured that the heat sealing between the PVC hard sheet and the medicinal aluminum foil is firm and reliable.

The RFY-05 packaging bag heat sealing performance tester from Jinan Sanquan Zhongshi, as a professional testing equipment, plays an important role in the packaging industry. The testing principle of the hot pressing sealing method used is simple and effective, which can accurately and quickly determine the heat sealing performance parameters of the material. By optimizing control parameters such as temperature, pressure, and time, the heat sealing quality and stability of packaging materials can be significantly improved. Therefore, the heat sealing tester is one of the equipment used by food production enterprises, pharmaceutical manufacturers, quality inspection centers, and packaging production enterprise laboratories.
