Application of packaging analysis and testing technology for dairy products

Abstract: dairy products play an important role in people's life as a routine consumer goods The soft packaging of dairy products takes a larger proportion in the whole dairy packaging industry with its unique advantages, and the quality control of soft packaging products is more and more prominent The following is the introduction of quality inspection and analysis technology of dairy soft packaging products Key words: dairy packaging analysis, dairy packaging testing, dairy packaging analysis and testing Dairy products, as conventional consumer goods, play an important role in people's life With the improvement of the quality of life, consumers are becoming more and more picky In order to meet the needs of consumers, many dairy manufacturers continue to launch new dairy products packaging to meet the needs Now, aseptic dairy products packaging, fresh-keeping dairy products packaging, steaming resistant dairy products packaging, square box type Roof type, soft plastic packaging, bottled and so on are emerging in an endless stream With its unique advantages, soft packaging of dairy products accounts for more and more proportion in the whole dairy packaging industry, and the quality control problem of soft packaging products is more and more prominent The following is the introduction of quality inspection and analysis technology of dairy soft packaging products 1、 Detection and analysis of composite strength of dairy soft packaging materials the soft packaging of dairy products in the market, such as aseptic pillow, aseptic brick are mostly composite plastic, composite paper The higher the composite strength is, the better the tear resistance or damage resistance is High viscosity and value can prevent the separation of composite layer After the composite material is processed into bags, it is likely to cause damage to the composite layer when exposed to harsh environment or affected by moisture and chemical composition The use of high viscosity adhesives will undoubtedly achieve high-quality composite, but the production cost will increase It can not only achieve the required composite, but also save costs, which requires the quality of composite layer to be tested and analyzed, in order to find the appropriate composite technical indicators At present, no matter domestic or imported tensile machines can be used for Peel test, but they are all general-purpose and simple force calculation The XLW (PC) intelligent electronic tensile testing machine of Labthink blue light is specially used for the test of soft packaging industry and fully complies with GB 8808-88 soft composite material peel test, unique function of pinching the head and removing the tail, use integral method to calculate the force value in the middle section; the result is accurate, real-time display of the force value and curve, judge the use of adhesive according to the measured force value; understand the uniform situation of the composite according to the fluctuation of the displayed curve; analyze the stability of this group of samples through curve superposition; and then based on this Adjust production process and composite parameters 2、 The test and analysis of the friction coefficient of the soft packaging materials for dairy products through the test of the friction coefficient of the packaging materials, the opening of the soft packaging bags and the packaging speed of the packaging machine can be controlled and adjusted At present, the equipment made in China has been in line with the international standards, and has a unique setting of vibration coefficient to adapt to different materials of film and paper, intelligent data processing, effective judgment of the confidence of the results of this group of samples, real-time display of large screen LCD curve, intuitive judgment of the uniformity of the friction coefficient of the material surface For manufacturers of packaging materials, the friction coefficient can be controlled by testing the type and content of opening agent and smoothing agent in the resin It can effectively control the quality of raw materials for the packaging manufacturers At present, the friction coefficient of dairy packaging is different because there are many applicable standards, such as gb10006 and ASTM The difference of test conditions in d1894, iso8295 and other standards makes the enterprises encounter many problems in the friction coefficient of packaging materials Labthink Languang mxd-02 friction coefficient tester has a number of standard test functions, which can meet the problems brought by different standards 3 Detection and analysis of the air permeability and moisture permeability of dairy soft packaging materials; the research on the air permeability and moisture permeability of dairy packaging materials is particularly important in dairy industry, which directly affects the quality of products This index can be measured by perme Bomi ox2 / 231 oxygen transmissivity tester of America mengkang, Denmark PBI and Labthink Languang Labthink ox2 / 231 oxygen transmittance tester uses Coulomb principle to test the oxygen permeability of soft packaging film, sheet materials and bottles, bags, cans, boxes and other packaging containers of dairy products The moisture permeability of dairy packaging materials can be tested and monitored by Labthink blue light's C series new water vapor transmission test system The equipment provides a wide range and rate of water vapor transmission test for medium and high water vapor barrier materials, which can be applied to film, sheet, paper, package and Water vapor permeability test of related materials 4、 Detection and analysis of heat sealing strength of soft packaging of dairy products heat sealing strength is an important performance index for packaging materials Any kind of soft packaging materials should be made into packaging bags to package all kinds of commodities, and packaging commodities should be sealed to achieve the purpose of packaging The sealing of dairy packaging must have a certain strength to be able to bear the gravity of a certain weight of the contents, so as to ensure that the commodity does not crack in the circulation process XLW (PC) intelligent electronic tensile testing machine can complete this test professionally, and the equipment can automatically read the data, automatically judge the force value, and can carry out data superposition analysis on the same group of samples In addition, if the laboratory wants to test the sealing strength (also known as the heat sealing strength test), it also needs to use the heat sealing tester to prepare the heat sealing sample 5、 Analysis on the tightness of dairy packaging the tightness of soft packaging is also an important performance index, especially in dairy packaging industry The tightness also has a great impact on the quality of products The poor sealing is the main reason for the leakage and corruption in the future There are many methods for sealing test The commonly used method is to use mfy-01 sealing tester, using the vacuum principle, and keep it at - 30KPa, - 50kPa, - 70kpa, - 90kpa for 0.5min according to the national standard During the test, pay attention to observe the leakage of the sample during vacuumizing and vacuum holding, and observe whether there is continuous bubble generation When there is isolated bubble, it is not considered as leakage Through the measurement of the tightness to measure the quality of packaging bags, and then to determine the rationality of the dense packing process 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, you can use the positive pressure principle sealing performance test equipment, such as lssd-01 leakage and sealing strength tester of Labthink Languang to conduct quantitative test 6、 The final purpose of dairy packaging is to promote sales The dairy packaging with exquisite appearance will undoubtedly attract consumers' attention and expand market share The density, density difference, color, color difference, overprint rate and printing contrast of dairy packaging and printing products can be measured by the spectrodensitometer of Ashley company of the United States; while for the detection of the combination fastness of the ink layer of dairy packaging and printing or the wear resistance of printing ink, the mcj-01a friction tester of Labthink blue light and blj-02 disc peeling tester can be used to detect, so as to achieve The purpose of controlling printing and color quality In the actual production, the analysis of the above several inspection indexes of dairy soft packaging is very important to adjust the production process and improve the product quality Through continuous tests, we can master various reasonable production parameters to guide the production of dairy packaging Jinan Languang mechanical and Electrical Technology Co., Ltd is a high-tech enterprise specializing in the R & D and production of packaging testing equipment and packaging testing services The existing equipment has been used in food, medicine, daily chemical products, packaging materials and printing, automobile, electronics and other industries, as well as third-party testing institutions, colleges and universities and other fields, and has been unanimously praised by customers For information about testing equipment and testing services, visit Jinan Languang company station or call for consultation The more you understand, the more you trust!
