The technical solution adopted by the utility model to solve the technical problem is: a high-seal PE square bottom valve bag, including an outer bag and an inner bag, and the upper left corner of the outer bag is connected with a valve port that communicates with the inside of the inner bag , the inner wall of the valve port is fixedly connected with a PE material inner film, and the valve port and the inner film are fixedly connected with a built-in magnetic sealing strip for closing the connection port between the valve port and the inner bag, and the outer bag The outer wall is located at the lower end of the valve port and is connected with an external sealed bag for closing the outer opening of the valve port. The inner wall of the external sealed bag is fixedly connected with a zipper mechanism for closing the valve port opening. The outer wall of the valve port An external magnetic sealing strip is fixedly connected to the opening position, and a metal strip group matched with the external magnetic sealing strip is fixedly connected to the inner wall of the external sealing bag.

Further, between the outer bag and the inner bag, there are fixedly connected vertical magnetic sealing strips on both sides of the lateral corners for improving the supporting force of the outer bag and inner sealing.

Further, the metal bar group is composed of two flexible iron connecting pieces of the same size that are movably connected.

Further, the flexible iron connecting piece is an arc-shaped connecting piece.

The beneficial effect of the utility model is that a high-seal PE square bottom valve pocket of the utility model is connected with a built-in magnetic sealing strip and an external magnetic sealing strip on the inner wall of the valve opening and the opening position, and the valve opening is lifted by automatic suction. The airtightness of the position, and the use of the zipper mechanism on the outer sealed bag and the arc-shaped flexible iron connecting piece to connect and close the valve port, and the outer bag and inner bag corners can be tightened through the vertical magnetic sealing strip , Automatically extrude the internal air, thereby improving the internal sealing.

detailed description

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

A high-seal PE square bottom valve bag shown in Figure 1 and Figure 2 includes an outer bag 1 and an inner bag 2, and the upper left corner of the outer bag 1 is connected with a valve port 3 that communicates with the interior of the inner bag 2, and the valve port 3 The inner wall of the PE material is fixedly connected with the inner membrane 4 of PE material, and the built-in magnetic sealing strip 5 for closing the connection between the valve opening 3 and the inner bag 2 is fixedly connected between the valve opening 3 and the inner membrane 4, and is used for mutual adsorption to close the valve opening 3 and the connection port between the inner bag 2, the outer wall of the outer bag 1 is located at the lower end of the valve port 3 and is connected with an external sealing bag 6 for closing the outer opening of the valve port 3, and the inner wall of the external sealing bag 6 is fixedly connected with a sealing bag for closing. The zipper mechanism 7 of the opening of the valve port 3 acts as a seal. The opening position of the outer wall of the valve port 3 is fixedly connected with an external magnetic sealing strip 8, and the inner wall of the external sealing bag 6 is fixedly connected with an external magnetic sealing strip 8.
