The bags appear to be polyester, but they aren't multi-layer foil laminated. I wouldn't trust them beyond a year if the storage humidity drops below 65%.
Where did you find this information? The bags are filled with product, then sealed. No metering of air or O2, no special packaging for any given blend.
That all makes sense. I double-bag the pound bags into 7mil foil laminate Mylar bags. Usually, I move everything into 4 or 8 oz Ball jars, but my recent Sutliff Spree has overwhelmed me. Besides, I'll be selling all these bags back to y'all in ten years, so they'll me worth more unmolested!
Well Mylar actually is just a special type of polyester that doesn't actually always have the foil layer... it usually does but that's actually a separate process it's put through whereas the Mylar itself is just trademark of biaxially oriented polyester. I'd assume the bags are either an unmetallized Mylar or a very high grade/multiply polypropylene. Pretty much nothing will beat a Mason I was just saying they're leaps and bounds above a ziploc. Either way though, they do let out some small amount of scent so I'll grant there is some obvious vapor transmission.. hence our double bag method probably being the best way to go.
And idk, unfortunately I left the gas chromatograph at the office but I just meant going off eyeballing it lolol
At least of the batches I've received, the full aromatics are straight vacuum sealed, the Virginias have generous airspace and the aromatic-English/hybrid blends seem to be somewhere in-between. Could it be coincidence? Sure, but it could also be that they just know from decades of experience what we've been discussing here and therefore give different sealing instructions based upon the blend... just my observation/supposition though.
And lmaoo, I hear ya brother. I keep telling myself (and the girlfriend) that I just dropped so damn much money and am surrounded by so many boxes full of bags and tins because I'm gonna beat the S&P500 with it one day but God truly knows it's either gonna go up in smoke in my own pipe, traded, or only be sold after I'm gone and unable to enjoy the proceeds. My problem is that I enjoy staring at hoards of tins/jars/bullion/bullets far more than I do numbers on a bank account screen. It gives me the warm fuzzies, what can I tell ya?
