I know there are a lot of smart "materials" people on here.....
I ordered some Kiwi-grip recently and it came in a "baggie" instead of a can. It was brilliant - I could pour out what I needed with no mess. Best of all, with the remainder I could squeeze out all the air right up to the tip of the spout and then put the screw on cap back on with absolutely no air inside!
Being a DIY guy, I thought this would be fantastic for all that leftover stuff I have after projects. Nothing worse than leaving 1/2 a can of varnish for 6 months and then expecting to come back to use it. I thought, OK, I know Kiwi-gip is water based, so if I tried to use these pouches for anything else it would be a disaster.
Well, I decided to spend $7 on Amazon and test a few liquids in the bags. Nearly all of the bags are advertised as sneaky liquor-carrying "flasks" and have food-grade claims - Food Grade", "BPA Free", etc. I am pretty sure 90% of the baggies sold on there all come from the same place and are made of the same stuff. I couldn't find any information there or on Google on what the pouches and caps are actually made of. Again, not holding my breath after reading the purpose of use.
I bought a cheap multi-size pack of pouches and poured several different liquids into them put them upside down (liquids right against the cap and the glue/heat melt area of the top). After 3 days now, in the engine room, there is no sign of leakage, deformation of the bags, or degradation of any of the materials.
This could be a game-changer for me! I would love to be able to put leftover paints, varnish, stains, and stuff in these baggies and get all the air out --- and then be able to pour out small amounts with a no-mess top! Not to mention they take up A LOT less space than 1/2 empty cans.......
The only real downside is you need a very small funnel to fill the bags the first time (at least one usually comes with the pouches). There are inexpensive 25, 50, and 100-packs of small disposable plastic
and paper funnels on Amazon also that would work for this, though, at very little cost. I think this would beat the propane/gas shot into the can thing for me, also.
I'm gonna continue let these sit and will report back if there are any breaches, but so far its looking really good. I am going to try a few other "caustic" chemicals in the remaining ones I have. If I went this route as a 'thing' I would still put the whole lot of any pouches in a tub for storage, well, you know, just in case......
Any thoughts or experience with these? Am I missing something?
Are they really impervious to Acetone and other things?
