A layer of plastic or paper bags containing the contents
Packing bag in a box means that there is a layer of plastic or paper bag inside the outer packing box to pack the contents. Compared with other packaging, bib packaging has the advantages of good economy, environmental protection and easy disposal, so it is widely used in food industry. At the same time, the quality control requirements are increasingly standardized. In addition to the quality and safety of the content itself, the quality, safety and testing of Bib packaging have attracted more and more attention of manufacturers. Then, combined with the differential pressure gas permeameter, sealing tester and torque meter, the gas barrier performance, sealing performance and cap opening force detection of Bib packaging are briefly introduced.
Gas barrier performance refers to the barrier effect of Bib packaging materials on oxygen. Gas barrier performance is an important factor affecting the quality of products in shelf life, and also an important reference for shelf life analysis. If the gas barrier performance of Bib packaging material is poor, it will lead to oxidation deterioration of the contents due to its sensitivity to oxygen. The gas barrier performance is measured by the gas permeability of the material, and the relevant standards are clearly specified.
The differential gas permeameter has excellent options, all indicators are better than the requirements of national standards or international standards, and its performance is stable and reliable. In addition to the gas permeability detection function, it also has the test function of diffusion coefficient, permeability coefficient and solubility coefficient, which can meet the research needs of the majority of scientific research institutions and colleges to analyze and improve the barrier performance of materials.
The value of locking and opening torque of Bib packaging bottle cap is one of the key process parameters for off-line or on-line control. Whether the torque value is appropriate or not has a great influence on the intermediate transportation and final consumption of Bib packaging products. It is controlled by microcomputer, easy to operate and friendly to human-computer interaction. It has double measurement mode of locking force and opening force, and the peak value is automatically maintained. The results can be displayed in various units and can be statistically analyzed. It is an indispensable test equipment in the production process with high measurement accuracy and good stability.
Of course, after ensuring that the gas barrier performance, sealing performance and cap torque index of Bib packaging are qualified, some other indicators such as sealing strength and tensile performance should be controlled to ensure the shelf life and applicability of the product. Jinan Languang Electromechanical Technology Co., Ltd. is willing to take this opportunity to enhance exchanges and cooperation with enterprises and institutions in the industry.
