how do mylar bags increase security?

how do mylar bags increase security? can't customs just open the mylar bag if they think it's suspicious or if its from a hot country? or does it just make them less likely to open it?

It's less permeable to letting smells out and it's a visual barrier. Lots of legit things are shipped in Mylar.

I really doubt there is such thing 'hot country'. Every country has millions and millions of letters/parcels send/received, no way incoming country post office pays more attention to letters from 'hot' places. IMHO you get lucky or not. I have been sending crazy letters with all possible stuff inside and sometimes really bad stealth - surprisingly all went through. Luck is the most important factor ...imho :)
