A paper bag structure enabling the bottom to be quickly opened

Abstract

The invention provides a paper bag structure enabling the bottom to be quickly opened. A paper bag side is connected with a paper bag bottom; a PE bag is connected with a first layer paper; the first layer paper is connected with a second layer paper; a PE bag adhesion part is connected with the other end of the PE bag; a second layer paper adhesion part is connected with the other end of the second layer paper; a first layer paper adhesion part is connected with the other end of the first layer paper; a bag body is located on one side of a fold line; a PE bag bottom is formed by folding the PE bag; a first layer paper bag bottom is folded by folding the first layer paper. The paper bag structure enabling the bottom to be quickly opened solves the problem that in the prior art, bottoms of paper bags cannot be unfolded quickly when it is need to injected-pack nanometer powder quickly; the bottom of the paper bag is provided with the rapid unfolding mechanism, so that the paper bag structure enabling the bottom to be quickly opened is formed; when the paper bag is used for injected-packing of nanometer powder materials, the bottom of the paper bag can be unfolded quickly with the injection of materials, so that the objective of rapid injected-packing can be achieved.

Description

technical field [0001] The invention relates to a paper bag structure, in particular to a bag structure with a bottom that can be quickly opened, which is applied in the technical field of packaging. Background technique [0002] At present, due to the widespread use of nanotechnology, the packaging of nanomaterials is also more demanding. Due to the characteristics of the tiny and light weight of nanomaterial particles, the filling speed of nanopowder materials is fast during filling, and the entire packaging paper bag can be filled instantly. Due to the light weight of the nano-powder material, the filling volume of the main body cannot quickly expand the bottom of the packaging bag with the existing structure to expand the capacity of the paper bag, but the bottom is still in a half-folded style, and the overall capacity of the paper bag is not fully covered by the nano-powder. The bulk material is filled, so that the relative proportion of the material cannot be filled a...

Problems solved by technology

[0002] At present, due to the wide application of nanotechnology, the packaging requirements of nanomaterials are also higher. Due to the small and light weight of nanomaterial particles, the filling speed of nanopowder materials is fast during filling, and the entire packaging paper bag can be filled instantly. Due to the light weight of the nano-powder material, the filling volume of the main body cannot quickly expand the bottom of the packaging bag with the existing structure to expand the capacity of the paper bag, but the bottom is still in a half-folded style, and the overall capacity of the paper bag is not fully covered by the nano-powder. The bulk material is filled, so that the relative proportion of the material cannot be filled and overflow the bag mouth, the environment of the production workshop is polluted by dust, and the sealing of the paper bag cannot be realized, which leads to the failure of filling; but there is no good solution to this kind of problem on the market. packaging bag; for this reason, the present invention proposes a paper bag structure that can be quickly opened at the bottom
