in recent years, self-supporting bag with mouth has the advantages of convenient opening of bottle and barrel packaging and multiple sealing, low consumption of packaging materials, high level of printing and decoration, and low storage and transportation costs of packaging materials, Garbage disposal consists of 23 capture groups, with small amount and other advantages, which is known as environmental friendly packaging, Experts all over the country have pointed out that it is necessary to mention the frame of the bicycle imitating the application condition here: "We should stop following the trend and hyping the varieties of popular new chemical materials such as graphene. The sealing performance of self-supporting bags with mouths and the torque of bottle caps directly affect the shelf life and adaptability of their products, which are strictly controlled by manufacturers. Labthink next, combined with mfy-01 sealing tester and njy-20 torque meter, we will briefly introduce the sealing performance of self-supporting bags with mouths and the detection of bottle cap opening force.

I. the sealing of self-supporting bags with mouths Performance test

sealing performance refers to the reliability of self-supporting bag sealing with mouth. Through this test, the integrity of the whole product package sealing can be ensured to prevent leakage, pollution, deterioration and other problems caused by poor sealing performance of the product. There are many methods to test the sealing performance. The most commonly used method is to use the sealing tester, such as the mfy-01 sealing tester of Labthink Languang. Using the vacuum principle, it is kept at -30kpa, -50kpa, -70kpa and -90kpa respectively for 0.5 minutes according to the national standard. For vacuum packaging, it is mainly to observe the recovery of the sample after the test. Of course, the above method adopts the principle of visual method, which is a qualitative test method. If you want to quantitatively detect the sealing and leakage performance of self-supporting bag with mouth, you can use the sealing performance test equipment based on the principle of positive pressure method, such as the lssd-01 leakage and sealing strength tester of Labthink Languang

II. Torsion detection of bottle cap with mouth self-supporting bag

the value of locking and opening torque of bottle cap with mouth self-supporting bag is one of the process parameters that the production unit offline or focuses on. Whether the torque value is appropriate or not has a great impact on the intermediate transportation and final consumption of self-supporting bags with mouths. The njy-20 torque instrument of Labthink Languang adopts microcomputer control, which is easy to operate and friendly to human-computer interaction; It has a dual measurement mode of locking force and opening force, and the peak value is automatically maintained. The results are displayed in multiple units and can be statistically analyzed; With high measurement accuracy and good stability, it is an indispensable test equipment in the production process

of course, after the sealing performance of the self-supporting bag with mouth and the torsion index of the bottle cap are qualified, other indexes such as sealing strength and barrier property need to be controlled to ensure the shelf life and use adaptability of its products.
