With the gradual improvement of people's living standards, the yoghurt consumer market is expanding and maturing. Yogurt plastic cup packaging has maintained a relatively fast development momentum over the years due to its good rigidity, elegant appearance, good surface finish, strong ink printing adhesion and excellent low temperature freezing resistance. However, packaging such as yoghurt plastic cups is not easy to open, plastic cup sealing is unsealed, and the quality of packaging of plastic cups during the storage and transportation process has also followed, which has become a common concern of various yogurt manufacturers. Based on the experience of the industry and relevant national standards, the quality of yogurt plastic cup packaging can be controlled from the following aspects:
1. Opening force (tearing force) and mechanical properties of yogurt plastic cup packaging If the sealing strength of the yogurt plastic cup packaging is too large, it is not easy for the consumer to open, and even if the pulling film is torn, it cannot be opened. Labthink's XLWPC intelligent electronic tensile testing machine can meet the test of mechanical properties of plastic cup packaging materials, such as heat sealing performance, tensile strength and elongation test, peel strength and tear strength. On the other hand, the plastic cup packaging opening force (tear force) can be measured. The tensile testing machine is equipped with a special opening force test fixture, and has professional software support. The test results can be statistically superimposed and analyzed to facilitate the manufacturer. Control sealing process. At the same time, the plastic cup packaging can be tested for puncture performance.
2, the sealing performance of yoghurt plastic cup packaging The sealing of yoghurt plastic cup packaging is an important indicator of the packaging inspection of yoghurt products. The inspection can ensure the integrity of the whole product packaging seal and prevent the leakage of the product due to poor sealing performance. Problems such as deterioration, effectively comparing and evaluating the sealing process and sealing performance of the package, and providing a scientific numerical basis for determining relevant production technical indicators. There are many methods for sealing performance testing. The common method used by Zui is to use a leak tester, such as Labthink's MFY-01 seal tester, using the vacuum principle, according to national standards, respectively, at -30kpa, -50kpa, -70kpa, - 90kpa is kept for 0.5 minutes. During the test, observe the leakage of the sample during vacuuming and vacuum holding, and observe whether there is continuous bubble generation. When the isolated bubble is not considered as leakage. Of course, the above method is based on the principle of visual inspection. It is a qualitative test method. If you want to quantitatively test the sealing and leakage performance of yogurt plastic cup packaging, you can use the positive pressure method to seal the performance testing equipment, such as Labthink LSSD. -01 leak and seal strength tester.
3. Barrier performance of yogurt plastic cup packaging The barrier property of yogurt plastic cup packaging is an important factor affecting the quality of its shelf life, and also an important reference for analyzing the shelf life. This test can solve the increase of oxygen content and humidity in the package. The rise of yogurt and the deterioration of dairy products. It can be said that in a certain sense, for the same yoghurt or yoghurt product (the process of processing is consistent), the barrier property of the packaging material is the main determinant of its shelf life. Therefore, barrier testing of packaging materials is essential for yogurt and dairy products. Labthink specializes in the study of barrier and permeation mechanisms and detection methods for polymers. It has developed a gas permeability and moisture permeability test device that meets all barrier test standards worldwide. It can realize films, sheets, bottles, bags, and special shapes. The detection of the barrier properties of the container for common gases such as oxygen, water vapor, carbon dioxide, nitrogen, helium, and air.
The performance test of the above yoghurt plastic cup packaging is very important in the actual production to adjust the production process and improve the product quality; through continuous testing, we can master various reasonable production parameters to guide the production of yogurt packaging.

Jinan Languang Electromechanical Technology Co., Ltd. is willing to enhance exchanges and cooperation with enterprises and institutions in the industry.
