Bubble Bag Mesh Sizes?

[SpacedCWBY]

Hello All Hashheads

I found a chinese company that sells bubble bags. Probably not the best, I know, but for the price they were asking - couldn't resist hearing them out. But what I didn't understand were the mesh sizes. First off, what should be the three main ones to use? Second, what would 40# mesh, 2400# and 2500# equate to? Are these useable for this purpose? These are the three sizes they claim to have.

Thanks.

These are very bad. A real 73um is #1800, in holes per inch. 220um is #800.

there's a chart on this link that may help you figure it out, I'm unfamiliar with the sizes quoted in your post, but that just don't sound right to me. We made our own bags from scrap mesh ( ok, most of it wasn't scrap, just a five finger discount ) and it worked great. 65 mesh for the initial mix, 110 for the first bag, 155 for the second, 230 for the 3rd, 305 for the 4th, and 355 for the last bag.

( before anyone flames me for the five finger discount, I worked as a printer at the time, all mesh was scrap left over from making screens and was headed to the trash bin anyway )

Thainks iLife. So these are like way too big and then WAY too small?

Thanks for the link OP. This material is cheap! Probably be a great place to get some stuff for making nice kif boxes.

What is a good complete set of bubble bags made up of? I've seen 3 bag sets and 9 bag sets. What are all the different levels for?

mesh is a standard for woven wire...
may refers to an industrial sizing standard for powder seperations...

there is a conversion on this page which says 40 mesh is 420 microns and 2500 mesh is 5 microns...
