As industrial products are stric in moisture prevent, usual in the process of production and storage ,we will take strick moisture proof precaution.And when speaking of moisture proof, there are two aspects . They are environmental moisture proof and packaging moisture proof.
Environmental moisture proof mainly refers to control the humidity in workshop, warehouse, production process and other place. usually ,use moisture dampers with humidity monitoring system to control the environment humidity . In some production turnover process ,also will use tiny electronic desiccant cabinet.
Packaging moisture proof refers to the stage of storage and transportation beore opening and using . During this stage, usual the final products are kept storaged for a few month or even longer.
In order to ensure the product safe and quality , we need to take moisture proof precautions to creat a dry sealed space.We usual use desiccant bag to control the moisture in the sealed packaging space.
The following below is the common humidity requirements of the industrial products. if over the humidity value ,means it is dangerous for product moisture damage.
| Industrial | Temperature requirements | Relative Humidity requirements |
| powders | 54-71℃ | 20% |
| Antibiotics packaging | 26-28℃ | 5-15% RH |
| Papers, prints | 27℃ | 20%-27% RH |
Precision machinery , watches , clocks | 24-27℃ | 35-40% RH |
| Biscuits and pastries | 16-18℃ | 50% RH |
| Fried potato chips | 24-27℃ | 20% RH |
| chocolate | 32℃ | 13% RH |
| chewing gum | 25℃ | 33% RH |
| nuts and dried fruit | 16℃ | 13% RH |
| Phototube vacuum assembly | 40% RH | |
| instruments | 60-63% RH | |
| Arms and ammunition | 10-50% RH |
