Title: Semi rigid batting options?
Post by: N8Smith on April 29, 2019, 01:16:53 PM
I'm currently producing a type of box bag and I have had a couple of clients ask if I can make it a little more rigid. The current composition is 1000d outer, 400d inner, and a premium felt batting (0.125"). Any suggestions on a different batting material that would make it a little more rigid but not increase the overall thickness? I'm considering an HDPE material but I'm worried about making it too rigid.

That's a tough one. You could mess around with very thin HD foam. You could also try replacing a layer with a Cordura laminate, like WTF's Acronym, or Squadron for even more rigidity.

1/16" closed cell foam, like volara

Have you been to your local fabric store and checked out their heavy duty stabilizer fabric? It's made for exactly your purpose and comes in various levels of stiffness......

These all seem like really good options to explore. I use squadron for my PC's and I hadn't thought of that... I'm also going to looks into the foam and stabilizer fabric.
Greatly appreciated!

Depending on the foam, you can laminate it to the fabric, by hand, with a product like 3M 9471 adhesive transfer tape.

Get an interlining that is super stiff. Can be sewn in or heat pressed depending on supplier.
Or use a laminate or stiff foam. As a small business, less than optimal options are usually the best ones.

There's a seller on ebay with Multicam and Coyote Tan498 500d laminated to 1/8" closed cell foam, looks like what was used for the issued Camelbak knockoffs.

  Anyhooo, it takes some practicing with but if you made your box pouch with a layer of it and some packcloth or 500d lining fabric, it would give your pouch some rigidity, protect some of the contents and help with noise discipline, stuff banging into  hard contents in the pouch with reduced noise. I started making a NVD 3X Magnifier Lens Pocket/Pouch that can be sewn directly to the helmet cover or made as a detachable pouch to hang on rig, ruck or on back of helmet cover.
