Quality testing of flexible packaging technology


And flexible packaging quality control problems has become increasingly prominent. In this paper, the techniques of flexible packaging quality test described below for reference. Support a set of flexible packaging materials in the Mo test Recovering strength of the material into bag, exposed to the harsh environment or affected by the moisture and chemical composition, complex sets layer is likely to cause damage. No doubt the use of high viscosity adhesive will reach high-quality rehabilitation units. However, the cost of production will increase. Both meet the requirements of the compound, but also cost savings,[link widoczny dla zalogowanych], which requires multiple sets of test quality layer analysis, in order to find the right technical elements of the complex units. An intelligent electronic devices used tensile testing machine 2 Sample preparation will be re-sets the width direction of both ends of the membrane to remove 50mm, width uniform along the sample and cut longitudinal and transverse samples of the 5 (sample width 15mm, length 200mm,[link widoczny dla zalogowanych], multiple sets direction is vertical), along the sample length of the base village of the composite layer and the pre-stripping 50mm. If the specimen difficult to peel. End of about 20mm can be immersed in the appropriate solvent treatment, special solvent has evaporated, then the peel strength test. 3 test steps to set parameters of the width of 15mm, speed 30mrn/min. Stripped part of the ends of the sample holder in the testing machine, respectively, the next fixture, the specimen axis and the upper and lower center of the connection weight bench fixture, and elastic fit to start the test. 4 results starting with the end of the pilot fluctuations, the device has automatically go head (25mm) to tail (10mrn) function, the middle section of the value of using integral for power, the results are accurate, this method automatically calculates the power of the purpose of domestic less the value of the equipment. According to the measured force values ​​to determine the use of agents, revolves around Taiwan, according to the volatility of the displayed curve to understand the uniformity of membrane complex situation of Taiwan, and then accordingly to adjust the production process, complex sets parameters. = Flexible sealing the Friends of cells Yan Feng strong seal strength measured in terms of packaging materials is an important performance requirements, must be made of any flexible packaging bags to package a variety of goods, packaged goods must seal to seal, to packaging purposes. An intelligent electronic instrumentation sampling tensile testing machine 2, respectively,[link widoczny dla zalogowanych], the flexible packaging bags side, back, top, bottom,[link widoczny dla zalogowanych], and heat units took part sample taken perpendicular to the direction (width 15mm expand the length of plug 100mm), when not taken to expand the length of the when the sample is 100mm. Adhesive pressure sensitive adhesive tape can be used to expand the sample length is 100mm. Test steps to set the width of 15mm 3 speed 300mmlmin to heat parts of the center line, was 180 to start. To sample both ends of the fixture are two folders on the test machine, so the sample axis and center of the upper and lower clamp connection weight bench, and elastic fit to start the test. 4 The results of the device to automatically read the data, automatically sense of value. To retain the Nn + -, has storage maximum, when the NN. x70% equipment judge shut down, display the maximum value when the specimen fracture. When the specimen fracture in the fixture, the sample set aside to do another sample taken Park. Hot stage was stronger than plastic film tensile force, they shall also consider the production process. According to the value to adjust the sealing force when the temperature of heat or hot Taiwan resin film thickness or surface treatment to achieve optimal production process. Three flexible packaging flexible packaging sealing sealing hammer test is also an important performance indicators, especially in food, pharmaceutical packaging industry, sealing will directly affect the quality of the product. A flexible seal test apparatus using the apparatus 2 is a representative sample preparation should be fitted with or mimic the actual contents of the flexible bag. Step 3 test vacuum chamber put the right amount of distilled water, immersed in the sample to ensure the water sample from the top and not less than 25mm, covered with sealing covers. According to national standard setting vacuum degree - (20,30,50,90 Kpa), and under this vacuum hold time (30s), start the test. 4 The results observed during the test note to maintain the vacuum and vacuum when the leak case during the sample, depending on the availability of continuous generation of gas hold when there are not as isolated bubbles leak. 4 by the sealing of the Lang set to measure the quality of bags, and then to determine the packaging process of Taiwan rational. Several indicators of the above analysis of flexible packaging testing in the actual production, the adjustment of production processes, improve product quality is essential, through continuous testing, you can master a variety of production parameters more reasonable. l I wire Zhusouliqi
