PE valve bag manufacturer from China, PE Labyrinth exhaust bag Special exhaust bag, PE valve bag with special air exhaust system bags are suitable for moisture-proof materials that require slow air exhaust
No.09
PE Labyrinth exhaust valve bag Special exhaust air bag, After filling is completed, residual gas remains inside the PE valve bag. This occurs because the air pressure inside the bag is higher than the pressure outside. The exhaust bag utilizes this pressure difference to allow the gas inside to escape through the vent holes, thereby reducing the internal pressure. When the internal pressure falls below the external pressure, the double-layer patch prevents external gas from entering the interior, providing a moisture-proof effect.
PE valve bag suitable for automatic filling machine, the robot can automatically grab the valve bag, especially suitable for Haver&Boeker automatic filling machine, ultrasonic heat sealing. The sealing can also be automatic closed. Especially suitable for powder packaging, the biggest problem of powder packaging is the air exhaust problem, so that the PE bag can not leak powder at the same time. Our bag solves this problem to the greatest extent, because the powder weight is greater than the gas, the exhaust hole straight out of the gas, the powder is left in the bag, to solve the problem of powder leakage. If you used to use paper craft bags and now want to change to PE valve bags, we are professional in this area, can design the size and provide sample bag testing.
