3 levels

3.1 According to the nature of the product, the flow of environmental conditions, moisture-proof period and other factors to determine the moisture-proof packaging level. 3.2 moisture-proof packaging level is generally divided into a packaging, two packaging, three packaging, see Table 1. Special requirements for moisture-proof packaging, according to special Special requirements for moisture-proof packaging. Table 1 moisture-proof packaging level grade condition Moisture-proof period of temperature and humidity product nature 1 level packaging 2 years Temperature is greater than 30 ℃, relative humidity At 90% Moisture-sensitive, easy to rusty mold or deterioration of the product, And expensive, sophisticated products 2-level packaging for 1 year Temperature between 20 ℃ ~ 30 ℃, relative Humidity between 70% ~ 90% Slightly sensitive to humidity products, more expensive, more sophisticated product 3-level packaging 0.5 years Temperature is less than 20 ℃, relative humidity is small At 70% Humidity insensitive products When the moisture-proof packaging level determinants can not meet the requirements of the table at the same time, should be in accordance with the three conditions of the most harsh conditions to determine moisture-proof packaging level. Also available In accordance with the nature of the product, moisture-proof period, temperature and humidity conditions in the order of comprehensive consideration to determine the level of moisture-proof packaging. For the special requirements of moisture-proof packaging, moisture-proof requirements are mainly higher packaging, should adopt more stringent moisture-proof measures. ......
