Apologies, micro is not my forte. We've been buying Whirl-Pak bags through a vendor and our last 2 shipments seem to have a powdery, cloudy substance on the inside of the bag. This is before breaking the seal that they swear up and down is aseptic/sterile.
My boss says don't use them, send them back. I've reached out to them to see if they have an answer, if it's a processing aid or something harmless. My question is, have you seen something like this? Do you manufacture plastic film and have seen similar clouding/powdery substance and can explain whether I should/shouldn't be worried? Sorry about the poor picture quality. Thanks in advance for any help you can provide.
