Deformable polybagged small part

A deformable polybag of small rigid parts such as screws, electronics or toys, modeled as a film shell with rigid contents for piece picking.

Also called bag of screws, parts bag or small parts bag.

How is the deformable polybagged small part modeled?

This is a small film bag, often with a zip or heat seal, holding loose rigid items. The film is a thin shell, and the items inside are separate rigid bodies that shift and settle when the bag moves.

Because the contents move, the bag's center of mass moves too. That is why bags of loose parts swing and slip in a gripper, and the asset keeps that behavior.

Which parts of the deformable polybagged small part deform?

Film bag
Thin shell that wraps around the contents
Rigid parts
Loose items inside

What ships in the USD?

One USD file per variant, with the render mesh, the simulation geometry and a physics material bound to it. Every value is set and named, so you can open it in NVIDIA Isaac Sim and run your task, or read the numbers into your own solver from the material JSON.

  • Thin shell. A thin surface with in-plane and bending stiffness, sealed or open, with contents modeled inside. Used for film, bags, cans and paper.
  • Rigid body. A body with mass, center of mass, inertia and a collision mesh, plus friction and restitution.

Where is it used?

  • Piece picking
  • Kitting
  • Bin picking

Industries: Logistics, Manufacturing, Retail

Questions

Which simulators does the deformable polybagged small part open in?

It ships as USD for NVIDIA Isaac Sim and Newton. We also deliver MJCF for MuJoCo and Genesis, a GLB mesh, and a JSON file with every material value.

Can it be matched to our real object?

Yes. Send us a sample, a drawing or a few photos and we set size, stiffness and friction to match your part.

How do we get it?

Choose your simulator, format and variant, then tell us where to send it. We prepare the files and email them to you.
