Just to put you at ease. As a Ph.D. chemist I can assure you that as long as the dehumidifier sachet does not come in direct contact with your camera or lens there is no possible way it can harm either one.
Are you saying that letting the desiccant packets come in contact with your cameras and lenses stored in a bag can cause harm to the equipment in some way? I have searched the internet for confirmation of that and I can't find it. I have used desiccant packets in bags and cases containing cameras and lenses for decades without any problems. Have I been doing it wrong??
