Mylar Pouch Tobacco Storage

[woodsroad]

Can you use an ordinary heat sealer, like the kind used for everyday kitchen use?

I don’t know exactly which sealer you are referring to, but…

FoodSaver machines (for channel bags) will not seal Mylar, and visa versa. Impulse sealers are made for and will seal Mylar.

teh method of heat sealing is the question for me.

the durability of the metal mylar sans window is not in doubt. Its what the military uses on its MRE. Seriously, if metal mylar without window can keep your houah bar nice an fresh for 30 years... it should be fine for your bulk purchase of sir walter.

Rereading this thread is interesting. A couple of posts state that they have read studies which state that there’s no difference between clear Mylar and metallized Mylar in regards to permeability. The ones I read state the opposite.

I recently posted a thread about opening a 22 year old Mylar bag of Haddo’s Delight, which had perfectly preserved the blend. It was, and still is as I continue to enjoy it, the best Haddo’s I’ve ever smoked, better than the contemporaneous tins I’ve smoked.

I have, in the past, bought tins that were sealed in clear Mylar that were over a decade old. They were dry, or dried out.

Screw around with this any way you want, I’ve found something that works.

As for heat sealing, I use a styling iron to melt the Mylar together. That’s the recommended method from where I buy my Mylar bags. It’s simple to do, takes 20 to 30 seconds per bag, and you have temperature control.

Will admit this machine has sealed 100+ pounds of bulk for me. Works very well with Mylar to suit your needs.

I forgot those vacuum sealers were so expensive.

But here is a secondary question. The ceramic flat iron for sealing as shown by mymylar.. no vacuum sealing what so ever.

But the other option is normally going to give a vacuum seal, and take away the air and any theoretical fermenting that can happen. SO is that your guys goal?

I wrote to the excellent customer service people at TopMylar.com and asked about the long-term storage of clear-front vs. opaque bags in an effort to put this to rest once and for all. Their response:

”Our clear front mylar bags use the same film as our other bags, except the front of the bag does not have the middle aluminum layer so the contents are visible. To maintain a 7 Mil thickness per side, we have an extra layer of clear mylar on the front of the bag. Because the aluminum layer lowers the oxygen transmission rate of the film and the omission of the aluminum would allow light into the bag, these bags are not made for long term food storage. They are typically used in situations when the contents will be consumed within 6-12 months. Our 7 Mil bags without the clear front are intended for long term food storage- up to 30 years depending on the food that is packaged.”

I asked for clarification that even in a dark environment, the clear-front bags would not be suitable for long-term storage. Their response:

”The light safe containers would help with food deterioration due to light (color fading, etc), however it would not help with the oxygen transmission rate. Since this rate is higher without the aluminum layer, oxygen can enter the bag over time. The transmission rate for these bags does not meet the specifications we have to designate a bag capable of long term storage.”

I stand corrected and educated. Hope this helps.

@Manawydan-thanks for sharing that.

Thanks. That’s very illuminating.
