The lining bag means that the inner layer of the outer carton has a layer of plastic or paper bag to package the contents. Compared with other packagings, the lining bag packaging has advantages such as economy, environmental protection, and easy disposal. Therefore, the application in the food field is rapidly expanding; at the same time, its quality control requirements are increasingly regulated; In addition to its own quality and safety, the quality and safety of the packaging of the bagged boxes has increasingly attracted the attention of various manufacturers. Labthink is a brief introduction to the quality control and testing of liquid food packaging liners in combination with differential pressure gas permeation, seal testers and torque meters. Jinan Languang Electromechanical Technology Co., Ltd. is willing to enhance exchanges and cooperation with enterprises and institutions in the industry.
1. Sealing performance test of liquid food packaging liner bag
Sealing performance refers to the reliability of the sealing of the bag packaging. This test ensures the integrity of the entire product packaging seal and prevents leakage, contamination and deterioration due to poor sealing performance. 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. For vacuum packaging, it is mainly to observe the recovery of the sample after the test. Of course, the above method is based on the principle of visual inspection, which is a qualitative test method. If you want to quantitatively test the sealing and leakage performance of the package of the liner bag, you can use the principle of positive pressure to seal the performance test equipment, such as Labthink. LSSD-01 leak and seal strength tester.
Second, liquid food packaging liner bag gas barrier performance test
The gas barrier property refers to the barrier effect of the packaging material of the liner bag on oxygen. Gas barrier performance is an important factor affecting the quality of the product during the shelf life, and is also an important reference for analyzing the shelf life. If the gas barrier properties of the liner bag packaging material are poor, it may cause problems such as oxidative deterioration of the contents due to sensitivity to oxygen. The gas barrier performance is measured by the amount of material gas permeation. The relevant standards clearly stipulate that the gas permeation test is tested in accordance with GB/T 1038-2000 Plastic Film and Sheet Gas Transmission Rate Test Method Differential Pressure Method. Labthink's VAC series of differential pressure gas permeation instruments are excellent in selection, and all indicators are superior to national or international standards. The performance is stable and reliable. In addition to the gas permeability detection function, it also has a diffusion coefficient and penetration. The test function of coefficient and solubility coefficient meets the research needs of analysis and improvement of the barrier properties of materials by scientific research institutions and colleges.
Third, the liquid food packaging liner bag cap torsion detection
The locking bottle cap locking and opening torque value is one of the process parameters of the production unit offline or online key control. Whether the torque value is suitable or not has a great influence on the intermediate transportation of the packaged bag packaging products and the final consumption of the zui. Labthink's NJY-20 torque meter is controlled by microcomputer, which is easy to operate and friendly to human-computer interaction. It has dual measurement mode of locking force and opening force, and the peak value is automatically maintained. The result is multi-unit display and can be statistically analyzed; It has good stability and is an indispensable test equipment in the production process.
Of course, after ensuring the gas barrier performance, sealing performance and cap torque index of the liner bag package, it is necessary to control other indicators such as sealing strength and tensile properties to ensure the shelf life and adaptability of the product. .
