Does Mylar show up as a big anomaly since its got metal in the bags? I've always wondered how it showed up on an xray machine at USPS or FEDEX. Does this not cause suspicion? I've googled and looked around and haven't found a straight forward answer. AND NO you saying "nah your good because my boy is like a scientist and shit he said so," doesn't count, give me some links, some proof. Would be much appreciated.
No it doesn't because mylar bags don't disguise, the x-rays see right through it. What causes anomalies is hiding your drugs in a place where there wouldn't be any organic material, like inside a tv. They also look for differences in density, say trying to hide cocaine in can of ground coffee, the picture will show a spot that looks different then the rest of the can even though both are organic.
