| High-efficiency Packaging This heavy-duty bag sealing machine uses specially designed clip chain system ensures that the packaging bag and sewing machine run synchronously, effectively ensuring the accuracy and stability of the heating process and improving the overall packaging effect. And it use 75mm hot melt tape cover sewing needle holes,the sealing effect is firm and smooth. | ![]() |
![]() | Easy Operation and Maintenance The operation interface is simple, it’s easy to use without operator guidance. After turning on the switch, just set the appropriate heat sealing and heat sealing temperature. |
| Multi-function The heavy bag continuous sealing machine can be applied to various types of bags, such as woven (composite) bag/PP or PE bag/aluminum plastic composite bag with PE inner bag. It can automatically achieve dust removal (optional), heat sealing, sewing, pressing, trimming bag opening, wrapping with paper tape, sewing and other processes. | ![]() |
![]() | Energy Saving And Environmental Protection Heat sealing and stitching machine with a 0.75KW air pump dust removal, it removes bag openings dust efficiently. When it detects that the package has reached a specified position, it will start the dust removal mechanism to remove the dust at the bag mouth. It can effectively reduce energy consumption and waste rate during the packaging process, reduce pollution to the environment, and meet the environmental protection requirements of modern society. |
| Connect With Packaging Line The transmission mechanism of the sealing machine adopts a special clamping chain, equipped with a frequency converter to achieve synchronization between the input of the packaging bag and the operation of the conveyor. It can form a production line with the conveyor, and can form a fully automatic packaging production line with automatic metering, automatic filling, stacking, arrow strapping and winding processes. | ![]() |
