Similar to hook-and-loop (velcro) but much stronger, this self-mating
fastener relies on hundreds of tiny interlocking mushroom heads to form its
bond. With five times the holding power of hook-and-loop fasteners, dual
lock provides a stiff connection that won't wiggle around like velcro, and
is also high-temperature and solvent resistant. Available in various types,
widths, and lengths. The variety I've tried is the SJ3560 clear
polypropylene with really strong acrylic adhesive and 250 stems per square
inch.

It's sold by RadioShack in small pieces under the name "Superlock"
(#64-2363), in Grainger stores in quantities as low as five yards, and by
many online suppliers. (The "low profile" variety sold by office supply
stores isn't nearly as stiff).

Be forewarned, this stuff is a lot more expensive than hook-and-loop--RadioShack's 1" x 12" package is about $4 (and being self-mating, will only give
you 1" by 6" of bonding area. For some reason, it's even more expensive in
bulk from Grainger or Mouser.

3M Hook & Loop

You can get some varieties at Home Depot or Lowes.

Something to be aware of with the more serious 3M hook and loop materials is how many times you can use it. The strongest stuff can only be opened and closed 10 to 15 times. Check your datasheet before figuring out which you need...
