Cracking of the edge seal and leakage of the seal... is a nightmare for countless food companies and a problem for suppliers of packaging materials. Heat sealing - the external condition is used to change the edge of the film to a viscous flow state. Under proper pressure, the two films are melted into one body, and after cooling, a certain heat sealing strength can be maintained, which is the most common sealing of the composite film packaging bag. Side craft. The above problems are mostly caused by the mismatch between the three parameters of heat sealing temperature, heat sealing time and heat sealing pressure. Heat seals of different materials and thicknesses often require constant adjustment of the test to determine the optimum combination of heat seal parameters to achieve the desired heat seal strength. The time and cost of this process is difficult to predict. Labthink's latest generation of heat-sealing and hot-adhesive performance tester, i-Thermotek 2400, restores a micro-site of a heat-sealing process, making it easy to study the optimal parameters of heat sealability and hot tack of different packaging materials, and maximizes Reduce time and cost. Heat seal performance test The instrument controls the upper and lower heat seal heads through the embedded system, and heat-seales the package samples under the set heat seal pressure, heat seal temperature and heat seal time. The instrument is equipped with three sets of upper heads and one set of lower heads, and two sets of three sets of heat seal tests can be completed at one time. All heads can be independently temperature controlled from room temperature to 250 °C. The heat sealing pressure is 0.05MPa to 0.7MPa, and the heat sealing time can be set freely within 99.9s. Heat seal strength test That is, the strength of the hot cover of the test specimen after the heat seal is completely cooled. The instrument has a built-in high-precision force value sensor and drive mechanism to measure the heat seal strength of the sample at test speeds of 200, 250, and 300 mm/min. During the test, one end of the sample is clamped on the right chuck, and the other end is clamped on the clamping seat. The driving mechanism drags the right chuck to make a relative movement with the clamping seat. After the sample is loaded, the sensor can be used. The corresponding electrical signal is obtained, and the heat sealing strength of the material is obtained through analysis. Hot tack performance test That is, the heat seal strength of the hot cover of the test specimen at the end of the heat seal without cooling. This index is suitable for evaluating the load-bearing capacity of the package-sealing of the bag-filling integrated production line that has not been cooled, and its suitability directly affects the filling efficiency and bag breaking rate of the production line. During the test, the two ends of the sample are respectively clamped on the left and right chucks of the instrument, and the sample is pulled into the hot-adhesive area. After the hot bonding is finished, the driving mechanism drags the left and right collets to make a relative movement. After the sample is loaded, the corresponding electrical signal can be obtained through the sensor, and the thermal adhesive force of the material is obtained through analysis and calculation. Labthink is committed to helping customers cope with packaging challenges and improving the quality and safety of packaging-related industries through the development of packaging inspection technology and the development of sophisticated inspection instruments.
