Analysis on how to improve the heat sealing strength of bag making machine

There are various faults in the operation process of the bag-making machine. Not only the performance of the faults is different, but also the causes and solutions are different. How to solve such problems as poor heat seal strength?
On the one hand, the heat-sealing and cold-cutting bag making machine can promote the hardening of the adhesive through heat preservation and aging, thus improving the composite strength and heat resistance of the composite film. At the same time, according to the composition and structure of the composite film and the heat sealing state, the best heat sealing condition or the improved heat sealing method shall be selected, but the cooling shall be carried out immediately after the heat sealing.
On the other hand, it is necessary to check the shelf life and storage conditions of some heat seal films, and increase the thickness of heat seal films; Or directly change the type and grade of the heat sealing film, and try to use the inner sealing film with anti-pollution heat sealing property. There is also the inspection of the quality of the adhesive, to ensure that it meets the requirements, and to control the content of the slippery agent and the content of the MDI monomer in the composite adhesive, so as to ensure a good heat seal.
