Convenient to use and affordable price, and the appearance is also very beautiful, very widely used. What should be paid attention to when making self-supporting zipper bag?
1. Heat sealing temperature
When setting the heat sealing temperature, we should consider the following factors: first, the characteristics of heat sealing materials; second, the thickness of plastic packaging film; third, the number of times of hot pressing and the size of heat sealing area. One
In general, the same part of the hot pressing times more, the heat sealing temperature can be set lower appropriately.
2. Heat sealing pressure
When heat sealing, proper pressure must be applied in order to improve the adhesion of heat cover materials. However, if the pressure is too high, the molten material will be extruded, which will not only affect the flatness of the bag
Analysis and exclusion will also affect the heat sealing effect of the bag and reduce the heat sealing strength.
3. Heat sealing time
The heat sealing time is not only related to the heat sealing temperature and pressure, but also to the performance of the heat sealing material and the heating method. The specific operation of self-supporting zipper bag should be based on different equipment and materials
Adjust during the actual test run.
4. Heating method
There are two kinds of heating methods of heat sealing knife in bag making: one side heating and two sides heating. The heating method on both sides of self-supporting zipper bag is more efficient and applicable than single side heating method. http://www.dgbpk.com/
