In a broad sense, mould proof packaging technology refers to a kind of packaging method to prevent the contents from mildew and affect the quality of the contents, such as moisture-proof packaging of the contents, sealing of dry air, sealing of the contents and packing box Anti mildew treatment was carried out "(GB / t4122.1-2008). Mildew and corruption of goods are referred to as mould rot. Mildew of goods refers to the mold that can be seen by naked eyes after the growth and reproduction of mold on the articles. The spoilage of goods refers to the decomposition of nutrients in articles caused by bacteria, yeasts and molds, which causes the articles to be invaded and destroyed and presents the phenomenon of decay.
Mould proof packaging is a kind of packaging which takes some protective measures to prevent the package box and its contents from moldy. In addition to moisture-proof measures, it is also necessary to carry out mildew proof treatment on wooden packing box materials. According to the physiological characteristics of microorganisms, the anti mold packaging must improve the production and control the packaging storage and other environmental conditions to achieve the purpose of inhibiting mold growth Protection function of wooden packing box Range. First, we should try our best to choose materials with good mildew resistance and tight structure, such as aluminum foil, glass and high-density polyethylene plastic, polypropylene plastic, polyester plastic and their composite films. These materials have the property of microbial impermeability and have good anti mold effect. Second, the wooden packing box should be well sealed, because the sealed packaging is an important measure of moisture-proof. For example, the use of tightly closed packaging such as bubble cover, vacuum and air inflation can not only prevent the invasion of external moisture, but also inhibit the growth and reproduction of mold. Third, fungicides can be added in the production of packaging materials, or soaked in wooden packaging boxes and sprayed with appropriate amount of fungicides in the packaging containers, such as using carbendazim (BCM), chlorothalonil, salicylic acid deaniline, bacteria bailing, sodium pentachlorophenol, etc., which can be used for mold prevention of paper and paper products, leather, cotton and hemp fabrics, wood and other packaging materials. Fourth, gas phase prevention can also be used
Mold treatment, mainly polyoxymethylene, nitrogen filled packaging, carbon dioxide packaging, also has good results.
For the products with low sensitivity to mold growth or low water absorption, and the volume of the packing box is larger, the plywood case Ventilation windows are set on the upper part of both ends to control the moisture content in the packing box. The function of the ventilation window is to prevent and reduce the condensation on the product due to the temperature rise and fall, resulting in mold growth of the product. Generally, unsealed packaging can be used for the products that have been effectively treated with mildew prevention or products with low sensitivity to mold growth.
