Usable period after opening moisture proof bags

SYMBOLUsable period after opening moisture proof bags

A = 168h

Products sealed in moisture proof packing should be stored in temperature below

30°C and relative humidity below 60%, and should be used within 168 hours (1 week),

after opened. If the products are kept beyond 168 hours (1 week) after opened, the

products should be baked for at least 20 hours at 125°C before mounted. After baked,

the products should be stored in temperature below 30°C and relative humidity below

60%, and should be used within 192 hours.

B = 72h

Products sealed in moisture proof packing should be stored in temperature below

30°C and relative humidity below 60%, and should be used within 72 hours (3 days),

after opened. If the products are kept beyond 72 hours (3days) after opened, the

products should be stored in temperature below 30°C and relative humidity below

60%, and should be used within 96 hours (4 days).

C = 48h

Products sealed in moisture proof packing should be stored in temperature below

30°C and relative humidity below 60%, and should be used within 48 hours (2 days),

after opened. If the products are kept beyond 48 hours (2 days) after opened, the

products should be baked for at least 20 hours at 125°C before mounted. After baked,

the products should be stored in temperature below 30°C and relative humidity below

60%, and should be used within 72 hours (3 days).

D = 24h

Products sealed in moisture proof packing should be stored in temperature below

30°C and relative humidity below 60%, and should be used within 24 hours (1 day),

after opened. If the products are kept beyond 24 hours (1 day) after opened, the

products should be baked for at least 20 hours at 125°C before mounted. After baked,

the products should be stored in temperature below 30°C and relative humidity below

60%, and should be used within 48 hours (2 days).

E = 12h

Products sealed in moisture proof packing should be stored in temperature below

30°C and relative humidity below 60%, and should be used within 12 hours, after

opened. If the products are kept beyond 12 hours after opened, the products should

be baked for at least 20 hours at 125°C before mounted. After baked, the products

should be stored in temperature below 30°C and relative humidity below 60%, and

should be used within 36 hours.
