Problems solved by technology

[0003] As far as the existing manufacturing method of the packaging bag structure is concerned, the manufacturing process is relatively simple by directly piercing holes, but the resulting micropores on the packaging bag of the deoxidizer will also bring some new problems For example, the content of the deoxidizer in the deoxidizer packaging bag is easily immersed by water and oil to destroy the composition of the deoxidizer formula, which in turn leads to the failure of the deoxidizer; moreover, the fine powder of the deoxidizer conten

Example Embodiment

[0021] The specific embodiments of the present invention will be further described below in conjunction with the drawings.

[0022] Such as Figure 1-Figure 3 As shown, the packaging bag structure 1 of the present invention includes a bottom layer 11 and a surface layer 13 covering the outside of the bottom layer 11, wherein the packaging bag structure 1 further includes a bottom layer 11 and a surface layer 13 At least one of the intermediate threads 12 is made of a breathable film, for example, a fiber with high breathability. In the present invention, the middle thread 12 can be arranged between the bottom layer 11 and the surface layer 13 by sewing, bonding, lamination, etc., and the middle thread 12 is preferably a hollow structure, that is, the middle thread 12 has a ventilation channel inside, and further, a plurality of ventilation holes 121 may be provided on the middle line. In addition, when there are multiple intermediate lines 12 according to the present invention,...

Abstract

The invention discloses a packing bag structure comprising a bottom layer and a surface layer, wherein the bottom layer is wrapped with the surface layer. At least one middle line is arranged between the bottom layer and the surface layer, and the middle lines are regularly distributed or irregularly distributed between the bottom layer and the surface layer. In addition, the bottom layer and/or the surface layer are/is provided with a layer of structure or multiple layers of structures. According to the packing bag structure, by means of arranging of the middle lines, the condition is provided for exchanging of air in package and air outside the package. By means of controlling of the quantity, inner diameters, distribution and the like of the middle lines, the exchanging amount/speed of the air in the package and the air outside the package can be effectively controlled. In addition, the packing bag structure has the properties of water proof, oil proof, damp proof and the like and can be applicable to deoxidizing agents, drying agents and freshness keeping agents for packing food and other products needing breathing.

Description

technical field [0001] The invention relates to a packaging bag structure, in particular to a packaging bag structure suitable for ventilation settings. Background technique [0002] In recent years, the quality and safety requirements of food products have become higher and higher, and the demand for using food deoxidizers to control oxygen in packaging bags has also intensified. Anaerobic storage has obviously become the current trend of food preservation. Anaerobic preservation can not only inhibit and alleviate oxidation, but also effectively prevent the growth and reproduction of aerobic microorganisms, and kill the growth of moths and the reproduction of eggs. However, the production process of the traditional deoxidizer packaging bag needs to perforate the packaging film or perforate the packaging film and then dislocate and compound them together. [0003] As far as the existing manufacturing method of the packaging bag structure is concerned, the manufacturing proc...
