1. Heat sealing temperature
The factors to consider when setting the heat sealing temperature are: firstly, the characteristics of the heat sealing material; The second is the thickness of the film; The third is the number of hot stamping times and the size of the hot sealing area. In general, when the same part is pressed more times, the heat sealing temperature can be appropriately set lower.
2. Heat sealing pressure
Proper pressure must be applied during heat sealing to promote the adhesion of the hot cover material. But if the pressure is too high, it will cause the molten material to be squeezed out, which not only affects the flatness and troubleshooting of the bag, but also affects the heat sealing effect of the bag, reducing 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 factors such as the performance of the heat sealing material and heating method. The specific operation should be adjusted during actual machine testing based on different equipment and materials.
4. Heating method
The heating methods of the heat sealing knife during bag making can be divided into two types: single side heating and double side heating. Obviously, the two sided heating method is more efficient and practical than the single sided heating method.
There are many problems with upright bags in actual production, but there are mainly two prominent problems: first, there is leakage or air leakage when holding goods; The second issue is the uneven bag shape and asymmetric bottom seal during the bag making process. Therefore, how to make a good choice of materials and adopt the best process operation method plays a decisive role in improving the overall quality of upright bags.
