Micro-zipper or zip-lock technology

Micro-zipper or zip-lock technology

(OP)
Hi!
Just a quick question on zipper (or alternative) technology:

I need an un-zip/re-zip a long volume the size of a shoelace (tiny).  I'd like to find a reliable means to do that- it could be a deformable ziplock type closure or a toothed zipper type closure, or something else, but the scale needs to be as small as possible.

It is not essential that it be air-tight, but that would be a plus, the tighter the better.  Flexible is also good, but not critical.

Of course a stronger seal is preferred, but I realize I can't have my cake and eat it too.

Minimal size trumps all other concerns in this case.   Thanks in advance for any suggestions!

How about a big BAGGIE??

I borrowed the zip lock (baggie) profile for the CAD model I made, but its really not durable enough.  I haven't actually found a suitable alternative yet, but I was hoping someone on the forum might have an idea.  Some of the tiny zippers might also be an option.

Imagine a Lego man's hand, C shape. Now imagine one of those "slide underneath the door and prevent drafts" cloth sock things, that you install a round cylinder into each side.

Now put the cloth tube thing, in the Lego man's hand, and put a cylinder through the tube.

Now make it fit your scale, and use a flexible single strand piece of wire or plastic.

The hand is on one end, the cloth loop on the other. Roll it together in a circle and install the wire. Adjust the surface condition of the cloth loop  (rubberize, or use different material) if you want it to be airtight.

Side view looks like this o------C

Zippertubing has been around so long that you may not have heard of it.  Let's fix that:

Thanks!
1gibson: thanks for the idea- I think I get it, but this needs to separate and reunite in the middle- similar to two "shuttles" on the same zipper (eg.a jeep wrangler window- but on a much smaller scale)

Mike:
Some of the products at that link constitute the closest thing I've seen yet!  Definitely will give them a call and find out more!  I guess 50+years isn't enough time for me to discover 'em!  :)
thanks!

Specialty waterproof/air tight zippers are made by TiZip http://www.tizip.com/ and YKK http://www.ykk-usa.com/

I looked very quickly and didn't see anything on your small scale in the standard line of products, but it's worth giving them a call I suspect.
