The automatic liquid packaging film testing - — Food packaging manufacturer film manufacturer

With the improvement of human quality of life, also more and more demand for beverage, dairy, so many liquid food factory continuously introduce new packaging to meet the demand, aseptic packaging, modified atmosphere packaging, cooking and box, rooftop, RuanSu packaging, bottled emerge in endlessly, such as liquid flexible packaging with its unique advantage in the proportion of the liquid packaging industry bigger and bigger, and the quality control problem of the flexible packaging products also more and more out. The following is a liquid flexible packaging product quality detection technology is introduced. A, automatic liquid packaging film of liquid flexible packaging material composite strength testing liquid flexible packaging on the market, such as milk products aseptic pillow, aseptic brick mostly composite plastic, composite paper. Flexible packaging composite strength is higher, the better, tear or damage to the ideal, can prevent the compound layer from viscous and values. Composite materials processing bags, after exposure to harsh environment or affected by moisture and chemical composition, composite layer is likely to cause damage. Using high viscosity adhesive will surely achieve high quality of the composite, but the cost of production will increase. Section can not only meet the requirements of composite, but also about the cost, this will require to test the quality of composite layer analysis, in order to find the proper composite technology. There is no matter domestic or imported tensile machine can peel test, but is common type, simple force value computation. Beijing LanDeMei LDX - g 200 electronic tensile testing machine major is suitable for smaller values of the flexible packaging industry force test, fully in line with the GB 8808 - 88 soft composite peel test, the unique function of break off both ends, the middle period of the integral method for force value; Results are accurate, real-time display force value and curve, according to the measured value to determine the use of adhesive conditions; According to the curve of the volatility understand composite uniform; Through curve superposition to analyze the stability of this group of sample; Then accordingly to adjust the production process and composite parameters. Second, liquid flexible packaging material of the friction coefficient of the detection for film packaging, the friction coefficient of thin film size directly affects the speed of the automatic packing machine. At present, through the Taiwan passches rand's MC - 600 friction coefficient instrument can accurately determine the coefficient of friction. For the production of packaging materials manufacturers, through the test can choose in the resin opening agent, smooth agent to control the type and content of the friction coefficient. For the use of packaging material manufacturer can effectively control the quality of the raw materials. Three, liquid flexible packaging sealing heat seal strength testing heat sealing strength is an important performance index for packaging material, for any kind of flexible packaging materials to make bags to packaging a wide variety of goods, packing of goods should be heat sealing to seal and packing. Sealing it is certain to should have the strength to withstand the weight of the built-in pressure, guarantee the goods not cracking in the process of circulation. Heat sealing the three major factors of heat sealing temperature, pressure, time, according to the different needs of different heat sealing. Four, the sealing liquid packaging testing soft packing seal is also an important performance index, the liquid packaging industry, in particular, sealing also has a great influence to the quality of the product. Bad sealing is the main cause of leakage of corruption in the future. Sealing test has many kinds of methods, the most commonly used method is to use the sealing test instrument, using the vacuum principle, respectively - according to the national standards 30 kpa, 50 kpa, 70 kpa, - Keep 0 90 kpa. 5 minutes, pay attention to during the process of test sample during the period of observation of vacuum and vacuum keep leaks, observe the presence of continuous air bubbles, when an isolated bubble is not as a leak. Through the determination of the sealing to measure the quality of the bag, and then to determine the rationality of the loading process. Five, the liquid in the inspection of the quality of other packaging packaging sales is the ultimate goal, the appearance of beautifully printed packaging will no doubt be fully attract the attention of consumers, to expand market share. Flexible packaging printing density, density difference, color, color difference, dieyin rate, printing contrast through the United States x-rite spectral density meter to measure, and to control the quality of the printing chip. The above several flexible packaging test index analysis in actual production, to adjust the production technology, improve the product quality is crucial, through continuous experiment, master all kinds of production parameters of reasonable, to guide the production of liquid packaging. The liquid automatic packaging film, food packaging film, film, film packaging, candy film bags, film manufacturer.
