Abstract

The invention discloses a packaging structure for regulating the release rate of chlorine dioxide, and relates to the technical field of packaging structures. The packaging structure for regulating the release rate of the chlorine dioxide comprises an activated slow-release layer and a protective controlled-release layer, the activated slow-release layer wraps a solid-phase chlorine dioxide preparation, and the protective controlled-release layer wraps the outer side of the activated slow-release layer; the water vapor transmission rate of the activated slow-release layer is 100-5000 g / (m<2>.24h); and the protective controlled-release layer is provided with one or more air holes. According to the scheme, the activated slow-release layer with high permeability is used for providing good moisture absorption and release characteristic, the protective controlled-release layer has a buffer effect, thus a more stable environment is provided for the activated slow-release layer, the impact ofexternal factors such as air disturbance on the release rate is reduced, and thus the release rate of the chlorine dioxide can be controlled more evenly.

Description

technical field [0001] The invention relates to the technical field of packaging structures, in particular to a packaging structure for regulating the release rate of chlorine dioxide. Background technique [0002] Epidemic diseases such as SARS, MERS, swine flu, avian flu, and 2019-nCoV that have broken out in recent years are mainly transmitted by droplets and air. Reducing harmful microorganisms floating in space will help reduce the chance of infection. [0003] At present, the commonly used methods of air disinfection include ultraviolet rays, ozone, hydrogen peroxide, etc. Chlorine dioxide is a highly effective disinfection ingredient that has been promoted and used recently, and can kill almost all bacteria (including methicillin-resistant Staphylococcus) and fungi (such as white Candida, Trichophyton rubrum, Aspergillus niger) and viruses (such as poliovirus, Coxsackie virus, Echo virus, hepatitis B virus, influenza virus, SARS), the disinfection effect is better tha...
