Hi, I have no experience of the ZIP TOP bag you refer to but my advice is to follow the guideline of IPC JEDEC 33 for sealing bags containing MSDs....it states' the MBB should be heat sealed'. I cannot imagine that a ZIP will keep the moisture out an

We don't use bags like you describe. All of our bags are ESD shield bags that have dissipative and antistatic attributes. We'd be uneasy about the zip lock closure thing. Use your static field meter to determine the charge generated by opening and

We have been receiving LEDs in these type of bags. The HIC says they are good. But we don't want to find out that there is a problem, at test or by customer returns. Does anyone reject them at receiving as not properly packaged when the parts are

I have level 3 components per J-STD-20. 1) Are there any packaging methods which can be "zip locked" instead of heat sealed? 2) Do I need to evacuate the bag? 3) Do I need to purge with Nitrogen?
