Stella,

Most packaging requirements  are very generic. Typically they would state something like "packaging must be done in such a manner that will protect the product from damage or degradation during transit".  I would suggest you be specific when specifying what ever packaging requirements you need to insure you receive produce in the condition you want to receive it. No one should know your product better than you. Hope this helps.

Hello dear fellows:
We are PCB contract manufacturer.  We had a case,  when the PCBs  were 
shipped overseas with no sealed plastic.  It was CEM1 material that 
absorbed  the moisture really fast.  I know that moisture inside the 
laminate could cause a lot of trouble, such as outgassing during curing, 
wave soldering etc. 
But I can not find any formal recommendations or standards how to package 
PCB.  Should we request vacuum sealed bags with the desiccant?  Is the zip 
lock bag with no desiccant good enough to prevent the moisture absorption?
Please, share you experience and knowledge.  All inputs would be greatly 
appreciated.
