Embodiment 1

[0033] The method for preserving the paper archives provided in Embodiment 1 is implemented in the following steps:

[0034] Step S30: Select packaging bags of different materials according to different sealing levels, put paper files into the file box, and put the file box into the packaging bag. Specifically, depending on the time requirements of the sealing level, select packaging bags with different materials. The reference standards for the sealing level are as follows:

[0035] The sealing level is: 10 years, and the above-mentioned packaging bag made of PE or EVOH is selected;

[0036] The sealing level is: 20 years, and the packaging bag made of composite film or co-extruded film material is selected;

[0037] The sealing level is: 30 years, and the above-mentioned packaging bag made of light-shielding film material is selected.

[0038] Step S40: Vacuumize the packaging bag by an automatic continuous packaging machine.

[0039] Step S50: Filling the packaged bag wi...

Embodiment 2

[0049] The present invention also provides a sealed archive bag used for the above-mentioned method for preserving paper archives, comprising paper archives, a packaging bag, and an archive box. The paper archives are located in the archive box, and the archive box is placed in the packaging bag. The inside of the bag is filled with carbon dioxide gas, and the volume of the carbon dioxide gas accounts for more than 60% of the gas volume of the packaging bag. Through many experiments, it can be known that the carbon dioxide content filled in the packaging bag should account for more than 60% of the internal gas capacity of the packaging bag, which can ensure that the pH value of the paper file does not change significantly, and the paper does not yellow, become brittle, and tear. No incomplete, no insects, no mold spots (colonies) occur.

Abstract

The invention relates to the field of article storing, in particular to a paper file storing method and a sealing file bag thereof. The storing method comprises the following steps that S30, packagingbags with different materials are selected according to different sealing grades, a paper file is arranged in a file box, and the file box is arranged in one packaging bag; S40, vacuum pumping treatment is carried out on the packaging bag; S50, carbon dioxide filling treatment is carried out on the packaging bag; and S60, sealing treatment is carried out the packaging bag. The invention further relates to the sealing file bag for the paper file storing method. According to the paper file storing method, the paper files can be stored for a long time, and the method enables the paper file to maintain good paper performance for a long time.

Description

technical field [0001] The invention relates to the field of article preservation, in particular to a method for preserving paper archives and a sealed archive bag used in the method. Background technique [0002] Existing grass-roots archives generally have disadvantages such as improper site selection, poorly constructed warehouses, and poor equipment. The warehouse cannot achieve the appropriate temperature and humidity required to preserve paper files, which can easily lead to the intrusion of harmful gases and microorganisms, resulting in the aging of paper files in stock. accelerate. Especially in the high-temperature and high-humidity climate in the south, mildew and insect damage to archives occur from time to time, causing varying degrees of damage to archives and human bodies. [0003] Chinese patent document CN102807036A discloses a mildew-proof and moth-proof device for wool, leather, and silk natural fiber clothing. ), humidity conditioner, oxygen concentratio...
