Vacuum-Sealer Bags Have One Side Smooth and One Side Textured Inside
Mylar bags are smooth, both inside and out, unlike food vacuum-sealer bags.
Mylar bags keep the light and air out, when sealed properly, and are easy to write on with a black felt-tipped pen/marker so you know what's in them!
The reason you can't vacuum these bags, (or is at least VERY hard to
do), is that both sides of the Mylar bag are smooth and there's no need to draw the air out. These Mylar bags are used for storing your filled vacuum-sealed bags.
The reason for the textured side in vacuum-sealer bags:
Food vacuum-sealer bags need to have one inner side textured. You need to have a way for the air to be drawn out when vacuum-sealing your packages that are filled with dehydrated food!
When you've filled your 10 inch x 14 inch bags, use a black felt tipped pen as mentioned above, to describe the contents of the bags. Write the date on it too!

I can get at least three plastic-wrap vacuum-packed packages into one bag, sometimes four. Don't overstuff. If you try to get more in, it makes it harder to seal the bag,
plus you risk puncturing the vacuum-sealed packages inside, when one
pokes against the other. That's the reason why I plastic-wrap the packages after vacuum sealing. For a 10 inch by 14 inch bag, a 300cc oxypack is used.
NOTE: To make sure you understand – we do not vacuum the Mylar bags, we only use the sealing function on the vacuum-sealer machine; not the air removal function.
Don't forget to check out Amazon for the best prices – and as you can see in the Amazon ads shown farther up the page, some Mylar bags come complete with a matching number of appropriately-sized oxygen absorbers!
