Abstract
The utility model discloses a two internal valve pockets of high gas permeability, including the bag body, set up the first valve port on the bag body, still be provided with the second valve port on the bag body, the oral area of second valve port is with gas permeability material shutoff oral area. The utility model discloses a valve pocket has increased an interior valve port in the kraft paper based on to it is preferred to increase a false valve port at the valve port offside and makes and form. The inner valve port contained a folded sheet of kraft paper with a PE film tail in the middle of the fold. When the valve port bag is manufactured, the valve port bag is bonded on a kraft paper bag barrel, one layer of inner reinforcing paper with the width being twice of the width of the port is added on the inner valve port, the inner reinforcing paper is used for manufacturing a false valve port, the part of the false valve port is not glued, and the valve port bag with high air permeability and double inner valves is manufactured through molding of the port.
Description
Technical Field
The invention relates to a packaging technology, in particular to a high-air-permeability double-inner-valve bag.
Background
When a current customer fills materials in a valve port bag, the requirement on the permeability of the valve port bag is higher and higher except for the requirement that the valve port bag has certain functions of preventing materials from returning and preventing materials from leaking, when part of the current internal valve bag is filled at high speed, powder can be sprayed out from the valve port, the pressure in the valve port bag is overlarge, and the material is prevented from falling onto a conveyor belt after the material is filled in the moment, the material carried by gas returns out from the valve port, the environment is polluted, and the material is wasted.
Disclosure of Invention
In order to solve the defects of the prior art, the invention provides a high-air-permeability double-inner-valve bag.
The technical scheme of the invention is as follows: a high-air-permeability double-inner-valve bag comprises a bag body and a first valve port arranged on the bag body, wherein a second valve port is also arranged on the bag body, and the mouth of the second valve port is sealed by an air-permeable material.
Further improvements of the invention include:
The second valve port is arranged on the bag body opposite to the first valve port, the air-permeable material is inner reinforcing paper, the inner reinforcing paper penetrates through the first valve port and the second valve port, the first valve port is fixed through gluing, and the second valve port is not coated with the glue material to ensure the air permeability of the second valve port.
The first valve port comprises an inner valve port, inner reinforcing paper and an outer bag, wherein the inner valve port, the inner reinforcing paper and the outer bag are sequentially arranged, and the first valve port is formed by a layer of folded kraft paper sheet and a trailing PE film in the middle of the folded kraft paper sheet.
The first valve port is composed of a layer of folded kraft paper sheet and a trailing PE film in the middle of the folded kraft paper sheet.
The width of the internal reinforcing paper is twice of the width of the valve port.
the invention is based on a kraft paper inner valve pocket, an inner valve port is added, and the valve is manufactured by preferably adding a false valve port on the opposite side of the valve port. The inner valve port contained a folded sheet of kraft paper with a PE film tail in the middle of the fold. When the valve port bag is manufactured, the valve port bag is bonded on a kraft paper bag barrel, one layer of inner reinforcing paper with the width being twice of the width of the port is added on the inner valve port, the inner reinforcing paper is used for manufacturing a false valve port, the part of the false valve port is not glued, and the valve port bag with high air permeability and double inner valves is manufactured through molding of the port.
The novel inner valve port and the novel false valve port are added, so that the problems to be solved urgently by most valve bag users are solved, and the novel inner valve port and the novel false valve port have the following specific advantages:
1. The valve bag does not need to be welded, sewn or operated by workers, and additional equipment is not needed, so that the use cost of a client is reduced.
2. The strength of the valve port of the valve bag with the double inner valves is very high, the valve bag cannot be broken due to tearing or overhigh air pressure in the bag, and the closing effect is greatly improved.
3. The gas permeability of the false valve port on the opposite side of the valve port is very high, so that the high-speed filling machine has good adaptability, and the production efficiency of customers is improved.

In the figure: 1. the outer bag, 2, one deck valve port paper, 3, two layers of valve port paper, 4, interior reinforcement, 5, barrel, 6, glue, 7, facial tissue.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
as shown in fig. 1 and 2, the high-permeability dual-inner-valve bag comprises a bag body and a first valve port arranged on the bag body, wherein a second valve port is also arranged on the bag body, and the mouth of the second valve port is sealed by a gas-permeable material.
The second valve port is arranged on the bag body opposite to the first valve port, the air-permeable material is inner reinforcing paper, the inner reinforcing paper penetrates through the first valve port and the second valve port, the first valve port is fixed through gluing, and the second valve port is not coated with the glue material to ensure the air permeability of the second valve port.
The first valve port comprises an inner valve port, inner reinforcing paper and an outer bag, wherein the inner valve port, the inner reinforcing paper and the outer bag are sequentially arranged, and the first valve port is formed by a layer of folded kraft paper sheet and a trailing PE film in the middle of the folded kraft paper sheet.
The first valve port is composed of a layer of folded kraft paper sheet and a trailing PE film in the middle of the folded kraft paper sheet.
The width of the internal reinforcing paper is twice of the width of the valve port.
The invention is based on a kraft paper inner valve pocket, an inner valve port is added, and the valve is manufactured by preferably adding a false valve port on the opposite side of the valve port. The inner valve port contained a folded sheet of kraft paper with a PE film tail in the middle of the fold. When the valve port bag is manufactured, the valve port bag is bonded on a kraft paper bag barrel, one layer of inner reinforcing paper with the width being twice of the width of the port is added on the inner valve port, the inner reinforcing paper is used for manufacturing a false valve port, the part of the false valve port is not glued, and the valve port bag with high air permeability and double inner valves is manufactured through molding of the port.
The novel inner valve port and the novel false valve port are added, so that the problems to be solved urgently by most valve bag users are solved, and the novel inner valve port and the novel false valve port have the following specific advantages:
1. The valve bag does not need to be welded, sewn or operated by workers, additional production or filling equipment is not needed, and the use cost of customers is reduced.
2. The strength of the valve port of the valve bag with the double inner valves is very high, the valve bag cannot be broken due to tearing or overhigh air pressure in the bag, and the closing effect is greatly improved.
