There are many problems in the actual production of vertical bags, but there are mainly two prominent problems: one is the leakage of liquid or gas when filling goods; the other is the uneven shape and asymmetric bottom seal in the process of bag making. Therefore, how to use the best process operation mode plays a decisive role in improving the overall quality of the vertical bag.
Requirements for bag making process of vertical bag with mouth: 1. The factors to be considered when setting the heat sealing temperature are: 1. The characteristics of heat sealing material; 2. The thickness of film; 3. The times of hot pressing and the size of heat sealing area. In general, the same part of the hot pressing times more, the heat sealing temperature can be set lower appropriately.
2. Heat sealing pressure proper pressure must be applied during heat sealing in order to promote the adhesion of heat sealing materials. However, if the pressure is too high, the molten material will be extruded, which will not only affect the flatness of the bag, fault analysis and troubleshooting, but also affect the heat sealing effect of the bag and reduce the heat sealing strength.
3. Heat sealing time heat sealing time is not only related to heat sealing temperature and pressure, but also related to properties of heat sealing materials and heating methods. The specific operation should be adjusted according to different equipment and materials during the actual test run.
4. The heating methods of the sealing knife can be divided into two types: one side heating and two sides heating. Obviously, the two side heating mode is more efficient and practical than the unilateral heating mode.
