Bubble envelopes are not intended to be sealed (no staples, tape, or otherwise). They are meant to be re-used and sealing them makes this difficult. The new white bubble envelopes are now coming with a seal edge. The vendor used to cut these off, but, since we have been ordering in such large quantities as of late, they have not been doing this. So, even though there is a seal flap, please do not use it to seal the envelope. Insert the item, but leave the bubble envelope unsealed.
Thanks for your cooperation.
