How to deal with the leakage of oil when the sealing of spicy sausage stretch packaging bag is not tight

Abstract: spicy sausage is a kind of common leisure food, most of which contain liquid components similar to oil It is usually packed by stretch packaging After the completion of packaging, oil leakage often occurs at the heat seal, which not only affects the image of the product, but also adversely affects the quality of spicy sausage In this paper, XLW (PC), an intelligent electronic tensile testing machine independently developed by Jinan Languang mechanical and Electrical Technology Co., Ltd., is used to test the heat sealing strength of the stretch packaging of spicy sausage, and the test principle, equipment parameters and brief test process of the equipment are analyzed, which has certain reference significance for spicy sausage manufacturers to solve the problem of heat sealing oil leakage Key words: spicy sausage, meat products, stretch packaging, plastic composite film, intelligent electronic tensile testing machine, sealing, oil penetration, aluminum plastic composite film, aluminum composite film, sealing edge, heat sealing strength, heat sealing strength, sealing strength 1, significance Spicy sausage has a unique taste, high content of protein, fat and other components, and contains some oil-like liquid components It's attractive in color and fragrance, and it's a regular meal delivery delicacy for people on leisure travel Under the bright development prospect of spicy sausage, the oil leakage of hot edge often occurs The oil in the light package penetrates into the hot edge, while the oil in the heavy package directly seeps out of the outside of the package, which not only reduces the brand image of the product, but also leads to the quality problems such as moldy and bulging of spicy sausage, which seriously affects the competitiveness of the enterprise's products 。 Fig 1 slight oil leakage phenomenon of hot sealing 2 Current situation (1) packaging form The common spicy sausage is mainly in the form of stretch packaging The packaging bag is composed of two parts: the cover film and the bottom film After the spicy sausage is put in, the cover film and the bottom film are formed by the hot sealing process This kind of packaging form has the advantages of beautiful appearance, convenient use, and consumers can directly see the color and shape of spicy sausage Fig 2 standard situation of spicy sausage stretch packaging form (2) At present, the test standard of heat sealing strength of plastic film packaging bags mainly refers to QB / T 2358-1998 test method of heat sealing strength of plastic film packaging bags 3 Sample a brand of spicy sausage packaging bag with oil leakage problem 4 In this paper, Labthink XLW (PC) intelligent electronic tensile testing machine is used to test the heat sealing strength of packaging bags Fig 3 test principle XLW (PC) intelligent electronic tensile tester During the test, the two ends of the sample are clamped on two clamps respectively, and the two clamps move relative to each other During the moving process of the dynamic clamp, the force value sensor automatically records the change of the force value in the process of the hot edge being damaged 4.2 there are two kinds of force value sensors with 500 N and 50 N equipment parameters available The test accuracy is 0.5 level In the industry, remote link is the first to effectively ensure the accuracy of the test results According to the relevant standards, the equipment provides seven test speeds of 50 mm / min, 100 mm / min, 150 mm / min, 200 mm / min, 250 mm / min, 300 mm / min and 500 mm / min, which can be set freely according to the requirements of the test standards The ultra long stroke of 1000 mm can be used to test materials with super large deformation rate Intelligent configuration of limit protection, overload protection, automatic return and power failure memory can ensure the operation safety of users A testing machine integrates seven independent testing procedures, such as tension, peeling, tearing, etc., providing users with a variety of test options 4.3 scope of application (1) this equipment can be used to test the tensile property, breaking force, tensile strength and deformation rate, tear resistance, peel strength, heat sealing strength, puncture resistance and other indexes of plastic film, composite film, thin film and other materials; it can be used to test the puncture performance of infusion bag cover, soft rubber bottle plug and oral liquid cover/ It can be used to test the unwinding force of adhesive tape, the pressure resistance of plastic bottle, the opening force of combined cover, jelly cup, yoghurt cup cover film and other products and packaging performance (2) the equipment can meet more than 20 domestic and foreign relevant standards such as ISO 37, GB / T 10004-2008, GB 8808, GB / T 1040.1-2006 ~ GB / T 1040.4-2006, GB / T 1040.5-2008, QB / T 2358, QB / T 1130, ASTM D 882, ASTM D 1938, ASTM D 3330, etc 5 Test operation step (1) cut out 10 sample strips with a width of 150 mm and a development length of 100 mm from the four hot sealing edges of the packaging bag with oil leakage (2) Set parameters such as sample width and test speed (3) Clamp the two ends of the sample strip on two clamps respectively, and the long axis direction of the sample strip shall coincide with the center line of the two clamps (4) Click the start test option to start the test The instrument automatically records the force value during the test and calculates the test results 6 The test results show that the average heat sealing strength of the upper edge is 4.632 n / 15mm, the average heat sealing strength of the lower edge is 3.016 n / 15mm, the average heat sealing strength of the left edge is 5.917 n / 15mm, and the average heat sealing strength of the right edge is 7.361 n / 15mm The low heat sealing strength of the four heat sealing edges is the main reason for the oil leakage of spicy sausage packaging bags 7 It is concluded that the sealing effect of packaging bag is the key factor to determine whether the packaging bag will leak air, liquid and oil Intelligent electronic tensile testing machine can be used to test the heat sealing strength of packaging bags The test results are accurate, the test accuracy is high, and the operation is simple At the same time, the instrument can also be used to test the peel strength, puncture resistance, tensile strength and deformation rate of packaging bags, with high cost performance Labthink Languang has always been committed to providing professional testing services and equipment for customers around the world, focusing on solving the problems in packaging for customers, to learn more about Labthink Languang's testing equipment and services, you can log in Languang to check the specific information of the equipment or call for consultation The more you understand, the more you trust!
