There are "specialty" products that can be used to vacuum-pack
(e.g.) foodstuffs. But, AFAICT, they all use "special" media
to do so -- special bags (that you are now dependent upon
for continued use of said product).
Does anyone make a vacuum sealer that can be applied to
more generic media? Or, does the medium need special
characteristics (e.g., air channels) to be useful?
E.g., when shrink-wrapping to a "card", you draw air
*through* that card (perforations) to pull the plastic
film down onto the card (and "set" it with heat).
Could you, for example, have a device that just took regular
plastic bags (Ziploc, "baggies", etc.) and use them for this
You are still saddled with "special media" (only to the extent that this
apparently is for Zip-Loc brand) but Zip-Loc makes a manual vacuum
sealer for their bags.
At only $9 it would be worth a shot.

But that seems to still use "special" ZIP loc bags. I.e., I wouldn't mind
using *normal* ZIP loc bags -- even if they were damaged (e.g., thermally
sealed) in the process. I just object to having to buy a bag made *just* for
that particular purpose -- and having to make sure I can continue to find
them in the future.
I know a business owner who vacuum seals his bbq and ships it anywhere
in the USA. I guess if it's worth using it's probably made specifically
for using for vacuum sealing at least until someone invents other options.
Let me add a "me too!!" to that . I'm betting that just the part of the seal
with the lines will allow this to work . My oldest and his wife gave me a
vac saeler a while back , haven't used it yet because of the special bag
needed . This rocks !
If you look at the top of the bag between the lock groove and the edge ,
there are some lines molded in , probably intended to give a better grip .
Those molded lines might act as evacuation vents . I'll have to dig my unit
out and try it .
Ah, OK. You're hoping they are "thick enough" to play the same role
as the (thick) zipper.
But, what would you gain by doing this? You'd still have cut off the
zipper (or, are you thinking you can keep the zipper and not "melt
seal" the bag)?
Those work great. BUT!
After thinking about it, reducing the small amount of air in the
container by half can't have a dramatic effect. Yes, every little
bit helps, but I'm not convinced it's the panacea that the youtubers
I does keep the lid on without the ring.
I save peanut butter jars because they have a seal in the lid.
If you poke a tiny hole in the lid and cover it loosely with
tape, like black electrical tape, you can suck the air out and seal
it with the tape. You need a different kind of interface to the
vacuum pump. The handheld foodsavers work fine. I did some test runs
and the seal was still good after a few months.
Never did anything with it because I keep coming back to the opinion
that vacuum sealing in a jar doesn't do much good.
There was a manual pump at reasonable price, but I don't recall the name
of it. I suspect they are gone as I can't find any information.
Using standard bags is cheaper, but they don't perform as well so
evaluate your use before going that route. Thin bags are more prone to
getting perforated in the freezer, plus, they don't offer as much of a
barrier. Thin bgs may be OK for a month with dry goods, but if you want
to keep frozen meat long term, use the thicker bags. They can be reused
I'm not averse to buying an electric pump/sealing unit. It's the
bags (consumables) that are annoying. How many do you keep on hand
(and where do you keep them) to ensure you aren't caught needing
another "box" -- or, worse, having to scramble to find a new
supplier when your previous source opts to no longer carry them.
[E.g., bags for trash compactors]
The thin bags would most typically replace those instances where we are
manually wrapping items with saran wrap before placing in bags/containers
of similar items. We currently use sandwich bags for nutmeats as a
"cup or two" is about all you can easily fit in such a bag and that,
coincidentally, is about the amount used in most Rx's.
With a vacuum sealer, I could skip the individual packaging and just
dump *all* the nuts (of a given type) into a single large, heavy-weight
bag (e.g., a gallon sized "freezer" bag -- instead of using that bag to
hold all the little sandwich bags full of nuts!) that I could later
open and reseal.
Likewise, put chicken breast portions in sandwich bags that are then
packed in a larger bag/container.
[And, in the normal course of use, that bag would end up getting
discarded -- so I'd not have to later fight with a "failing zipper"
for a bag that should have been discarded BEFORE being refilled,
We spend a lot of time "saving money" (?) -- buying in larger quantities
and then repackaging. I typically dread "shopping day" (annoying
chore that competes with more interesting activities). But, on those
days when we buy pork, chicken, nuts, etc. -- anything that has to be
repackaged -- it is *doubly* dreadful! It's like the few hours of
shopping have now been extended by a few more *inside* our home! :<
[At least we don't have to fight for a parking space, here! :> ]
