How is the block valve pocket sealed?

The block valve pocket is seamed up and down, leaving a feed port for the machine. The packaged product is loaded into the valve pocket from the filling port under the action of pneumatic or mechanical power. The square valve pocket bag of the interface agent has a color-coded woven cloth valve pocket, a paper-plastic composite valve pocket and a kraft paper-filled valve pocket. The three materials are moisture-proof. The first two are woven bags to protect against moisture, and the latter one is film-proof. The valve port is protected from moisture, and the valve port has an inner orientation and an outer orientation, and the sealing effect is still possible.
The outstanding advantages of the square valve pocket are non-toxic, odorless, non-polluting and in line with national food hygiene standards. Due to the good printing performance of the paper, graphic characters can be printed according to the requirements of the user. The valve paper bag made of this paper is very convenient and quick in the filling process of the flour, the filling speed can be increased by 3 times, and there is no dust flying, which can improve the working environment. In addition, since the valve bag is rectangular after filling, it is easy to palletize and should not be slipped. The storage capacity can be increased by 10% under the same stocking capacity, and the handling process is not contaminated with the operator's clothes. In view of the above various advantages, the industry believes that the promotion of the use of paper grain packaging is inevitable in the future replacement of food packaging, and is also the development trend of food packaging in the future.
