There are many kinds of fumigation free packing boxes. From different production materials, they can be divided into hard fumigation free packing boxes, semi-hard fumigation free packing boxes and soft fumigation free packing boxes.
For example, hard fumigation free packing boxes include iron cans, tin cans, porcelain bottles, glass bottles, craft small wooden boxes, small bamboo boxes, craft carved gold-plated boxes, etc; Semi hard fumigation free packing box with various cardboard boxes; Soft fumigation free packing boxes include paper bags, plastic food bags and various summer bags.
The design of fumigation free packing boxes can be designed with appropriate materials according to different needs.
The main reason why the fumigation free wooden box will be moldy is that the fumigation free wooden box contains water.
Internal reason: internal reason we mainly say that the moisture content of the wooden box after heat treatment is still relatively heavy, which does not meet the moisture content of the export standard, or the moisture content of some wooden boxes is relatively heavy, which is also the reason why others say that the moldy under the wooden box is more severe, and the wooden box panel is not moldy, which is because the local moisture is relatively heavy. External causes: generally, fumigation free wooden cases will not get moldy after heat treatment.
Moldy here mainly refers to external causes. For example, humidity, plum rain season or outdoor rain lead to excessive moisture in wooden cases.
These are the factors that cause moldy wooden cases, which is what we call external factors, Another possibility is that in the exported containers, for example, due to the large temperature difference between day and night at sea, condensate will form and drip on the wooden cases.
Generally, we know that the time at sea is basically 1-2 months, that is, the wooden cases have been subjected to high temperature and humidity for 1-2 months, which naturally brings opportunities for the reproduction of molds, This is what we call the external cause of the moldy wooden case.
