Abstract: The heat sealing of the package is a barrier to the contents of the package independent of the external environment. The proper heat sealing strength is a necessary condition to ensure the good sealing of the package. The heat seal strength of the package is directly related to the heat seal parameters acting on the heat seal, such as heat seal temperature, heat seal pressure and heat seal time. In this paper, taking the meat-boiled packaging as an example, the HST-H3 heat - sealing tester independently developed by Jinan Languang Electromechanical Technology Co., Ltd. is used to determine the appropriate heat-sealing parameters of the meat emulsion package, and the test principle and the brief steps of the test are introduced. It provides a reference method for enterprises to explore the heat sealing parameters of packaging. Key words: soft plastic packaging, heat seal tester, heat seal strength, seal strength, heat sealing, heat sealing parameters, meat emulsion, meat products 1 , meaning Heat sealing strength, also known as sealing strength, refers to the sealing bond fastness of the heat sealing edge of the bag. By heat-sealing the heat-sealing edge, a barrier that separates the packaging bag from the external environment is formed. If the heat-sealing strength of the packaging bag is unsuitable, the package may be leaky or leaking, or the heat sealing portion may be Broken bag occurs, so the proper heat seal strength is of great significance to ensure good packaging quality. The heat sealing parameters applied to the heat seal have a direct influence on the heat seal strength of the package. Therefore, how to determine the heat seal parameters of the package is particularly important. Known as the first of the eight cadres of Minnan, the meat broth is refined by dozens of processes using traditional techniques. The shape is neat, the color is bright, the fragrance is tempting, and the nutrition is rich on the basis of color and flavor. Features. The good heat-sealing strength of the meat emulsion package plays a vital role in preserving the flavor of the meat emulsion, maintaining its bright color and preventing mold and deterioration. 2 , the status quo At present, there is no relevant standard for determining the heat-sealing parameters of soft plastic packaging in China. This paper verifies according to American Standard ASTM F2029-2008 "Testing Method for Determining Heat Sealing Performance of Soft Plastic Packaging by Measuring Heat Seal Strength". 3 , test samples A brand of plastic composite film for meat packaging. 4 , test equipment In this paper, the Labthink blue light HST-H3 heat seal tester is used to select and study the heat sealing parameters of the sample. 4.1 Principle The device is heat-sealed by means of hot-press sealing. By adjusting the values ​​of three heat-sealing parameters such as heat-sealing temperature, heat-sealing pressure and heat-sealing time, the sample is heat-sealed under different heat-sealing parameters, and then tested. The heat sealing strength is determined according to the heat sealing strength value of the sample, the flatness of the heat sealing edge and the damage of the heat sealing portion of the sample. 4.2 Scope of application (1) This equipment is suitable for heat sealing test of soft plastic film, jelly cup cover, plastic hose and other types of samples. Soft plastic film includes various plastic film, plastic composite film, paper-plastic composite film, co-extruded film, Aluminized film, aluminum foil, aluminum foil plastic composite film, etc. (2) Applicable to domestic and foreign standards such as ASTM F2029 and YBB 00122003 . 4.3 Equipment parameters 5 , the test process (1) 40 pieces of specimens having a length of 15 cm and a width of 10 cm were cut in the longitudinal direction of the sample . (2) Fix the heat sealing pressure and heat sealing time of the heat seal tester to 0.35 MPa and 1.0 s, respectively . (3) According to the material of the heat sealing layer of the sample, the heat sealing temperature of the upper and lower heat sealing heads is set to 100 ° C. After the equipment reaches the set temperature, any two samples are taken, and the heat sealing layers are in contact with each other. After that, heat sealing is performed. (4) A heat-sealing temperature is set every 5 °C , and the sample piece is heat-sealed until 195 °C or the sample is significantly shrunk. (5) from each sheet are heat sealed good specimen sample strip cut out to a width of 5 15 mm. (6) Test the heat seal strength of the sample strip and record the failure mode of the sample. 6 , test results According to the corresponding heat seal strength results of the samples at different heat sealing temperatures, the heat seal strength curve is drawn, as shown in Fig. 3 . After 170 °C , the damage of the sample occurred at the root of the heat seal. After 180 °C , the heat seal edge showed obvious shrinkage. Therefore, the package was prevented from being broken at the root of the heat seal or the heat seal of the package was not tight, and the package was kept. From the perspective of aesthetics and other aspects, the temperature of the ziujia heat seal of the meat bag sample should be controlled within the range of 140 °C ~ 155 °C . 7 , conclusion HST-H3 heat seal tester is a test equipment specially used to verify the heat seal parameters of soft plastic packaging. It has the advantages of strong operability, reliable test and high test efficiency, which can effectively solve the packaging caused by improper setting of heat seal parameters. Poor sealing or easy to break bags and other problems that plague enterprises. In addition to soft plastic packaging, through specialization, HST-H3 can also be used to explore the heat sealing parameters of packaging film, plastic hose and other packaging, if the cover film of the frozen cup and the cup, the end of the toothpaste tube.
