Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Figures 1, 2, 3, and 4, a valve bag with automatic opening function includes a paper bag body 1, an upper bottom 2, and a lower bottom 3; with the paper bag body 1 as the base, the upper bottom 2 and The lower bottom 3 is respectively arranged on the upper end and the lower end of the paper bag body 1; it is characterized in that: the upper bottom 2 is provided with a valve port structure 4; one end of the valve port structure 4 is arranged at the side of the paper bag body 1, and the other One end is arranged inside the paper bag body 1;

The valve port structure 4 is a valve port structure 4 that opens automatically; the valve port structure 4 includes paper and is surrounded by the paper; the shape of the valve port structure 4 is a flat compressed shape;

The upper bottom 2 of the paper bag body 1 is provided with a knuckle area 16, and the knuckle area 16 is provided with glue, which is the first glue 17; the valve port structure 4 is bonded to the knuckle area 16 through the glue;

Described paper bag body 1 comprises paper and PE film 5; Described paper is arranged on the outside of PE film 5, is provided with glue between described paper and described PE film 5, is the second glue 10; Described paper passes this glue Bonded together with the PE film 5; the paper is one or more layers of paper; the PE film 5 is a high-strength barrier film;

Specific embodiment one: as shown in Figure 1 and Figure 2, a valve bag with automatic opening function, including a paper bag body 1, an upper bottom 2, and a lower bottom 3; with the paper bag body 1 as the base, the upper bottom 2 and the lower bottom 3 are respectively arranged on the upper end and the lower end of the paper bag body 1; the paper bag body 1 includes the first paper 6, the second paper 7 and the PE film 5; the second glue is applied on the inner side of the second paper 7 10. Bond the first paper 6 and the second paper 7 together; then also apply the second glue 10 on the inner side of the first paper 6, and bond the first paper 6 and the PE film 5 together; here PE The film 5 adopts a high-strength barrier film; this structure uses the second glue 10 to quickly bond the first paper 6, the second paper 7 and the PE film 5 together, ensuring the paper-film composite structure of the paper bag body 1 at the seam. Rapid bonding and forming, at the same time, it also plays a role in strengthening the firmness of heavy-duty packaging of paper bags;
