Abstract: The opening force of the French fries paper cup sealing film is one of the performance characteristics of food production enterprises that are controlled offline or online . In this paper, the XLW (EC) intelligent electronic tensile testing machine is used to test the opening force of the French fries paper cup sealing film. The monitoring method, test principle and equipment parameters of the French foil cup sealing film opening force are introduced. Provide reference for monitoring the opening force of the French fries paper cup sealing cover film and selecting the corresponding testing equipment. Key words: French fries, paper cup, sealing cover film, opening force, sealing strength, intelligent electronic tensile testing machine 1 , meaning French fries are fried puffed foods that contain large amounts of oils and proteins. In order to prevent the fries from appearing in the storage and circulation , the package should have high barrier properties and good sealing performance. The commonly used packaging on the market is in bags and drums, and gradually derived from paper cup packaging. The paper cup packaging uses the cover film and the edge of the cup body to be heat-sealed to seal the product, thereby achieving the sealing effect. At the same time, the paper cup itself has a high barrier performance, which can effectively prevent the infiltration of oxygen and water vapor in the outside air. The opening force of the French fries paper cup sealing film is also called sealing strength or heat sealing strength. In order to ensure the sealing performance of the French fries paper cup, the French fries producer can achieve the heat sealing strength of the sealing. If the sealing heat sealing strength is too large, the sealing cover film is not easy to open, which directly affects the consumer's consumption experience; if the sealing strength is too small, damage and leakage may occur during storage, transportation or sales, which may result in the fries being no longer edible, affecting the product. Image. Therefore, the French fries producer should add effective monitoring of the opening force of the paper cup packaging closure film. Figure 1 French fries paper cup packaging 2 , the implementation of standards At present, there is no corresponding standard for the detection of the opening force of the paper cup closure film in China. In this paper, the opening force (or seal strength) is tested by means of special equipment and fixtures to simulate the opening method of the French fries paper cup cover film. 3 , test samples The finished paper cup packaging provided by a French fries product factory. 4 , test equipment In this paper , the XLW (EC) intelligent electronic tensile testing machine independently developed by Languang is used to test the opening force of the sample. Figure 2 XLW (EC) intelligent electronic tensile testing machine 4.1 Test principle The sample is clamped between the two clamps of the special clamp, and the two clamps are moved relative to each other. The force value sensor located on the movable clamp head and the displacement sensor built in the machine collect the force value changes during the test and The displacement changes to calculate the heat seal strength, tensile strength, deformation rate, peel strength and other performance indicators of the sample. 4.2 Scope of application (1) This equipment is mainly used for plastic film, composite materials, soft packaging materials, plastic hoses, adhesives, adhesive tapes, stickers, medical patches, release paper, protective film, paper cup cover film, Opening force, stretching, peeling, deformation, tearing, heat sealing, bonding, puncture force, low speed unwinding force, peeling of products such as composite cover, metal foil, separator, back sheet material, non-woven fabric, rubber, paper, etc. the opening force of the performance tests, such as oral tearing force of the lid, the piercing / drawing force, puncture force infusion bag cover, soft rubber stopper piercing / drawing force and the like. (2) This equipment meets many national and international standards, such as GB 8808 , GB/T 1040.1 , GB/T 1040.2 , GB/T 1040.3 , GB/T 1040. 4 , GB/T 1040.5 , GB/T 4850 , GB /T 12914 , GB/T 17200 , GB/T 16578.1 , GB/T 7122 , GB/T 2790 , GB/T 2791 , GB/T 2792 , GB/T 17590 , ISO 37 , ASTM E4 , ASTM D882 , ASTM D1938 , ASTM D3330 , ASTM F88 , ASTM F904 , JIS P8113 , QB/T 2358 , QB/T 1130, etc. 4.3 Equipment parameters 5 , the test process (1) The sample to be tested is placed in the cup holder of the special opening device used in the paper cup, and the space between the French fries cup and the cup holder is vacuumed by a vacuum generator, and the fries cup is fixed by atmospheric pressure. (2) Fix the opening of the French fuch cup sealing film on the upper jig . (3) Set the test parameters. (4) Click the test start option, the test starts, the upper clamp is raised at a constant speed of 300 mm/min , and the sealing film is torn open. (5) The equipment automatically records the large force value of the Zui as the opening force, and the average value in the peeling process is the sealing opening force, and reports the test result of the Zui end. 6 , test results The opening force fries cups were 35.356 kN / m, 31.478 kN / m, 38.189 kN / m, 33.357 kN / m, 40.475 kN / m. 7 , conclusion XLW (EC) intelligent electronic tensile testing machine is a professional testing equipment for testing the heat sealing strength of French fries paper cups. It has the advantages of simple test operation, high intelligence, accurate test results and high test accuracy. XLW (EC) intelligent electronic tensile testing machine can not only be used for heat sealing strength test in food industry, but also can be used for testing the tensile properties, peeling, puncture force and drawing force of pharmaceuticals, daily chemical and other industries.
