With the increasing demand for various paper bags, we will often care about its diversified characteristics in production, such as the emergence of paper vertical bags, to give a lot of goods better display opportunities, so it has been favored by more businesses, in the face of more and more market demand, this paper bag machine in the production process what are the requirements?
1, heat sealing temperature
The factors that need to be considered when setting the heat sealing temperature are the characteristics of the heat sealing material; Second, the thickness of the film; The third is the number of hot sealing pressing and the size of the hot sealing area. Under normal circumstances, the same part of the press more times, the heat sealing temperature can be appropriately set lower. For the height of the temperature, we can set it according to the actual situation.
2, heat sealing pressure
When heat sealing, appropriate pressure must be applied to promote the adhesion of the hot cover material. However, if the pressure is too large, the molten material will be extruded, which will not only affect the flatness of the bag, but also affect the heat sealing effect of the bag and reduce the heat sealing strength.
3. Heat sealing time
In addition to the heat sealing temperature and heat sealing pressure, the heat sealing time is also related to the performance of the heat sealing material, heating method and other factors. The specific operation should be adjusted according to different equipment and materials in the actual test.
4. Heating method

The heating method of the hot sealing knife can be divided into two categories: unilateral heating and two side heating. Obviously, the two sides of the heating method is more efficient and practical than the unilateral heating method, and the heating efficiency is higher, so in some efficient paper bag machine equipment, the use of bilateral heating equipment accounts for the majority. For the vertical bag production equipment needs to have some characteristics, we will introduce here, I hope to help you.
