Soft packaging

Deformable polybagged apparel item

A deformable polybag with a folded garment inside, modeled as a thin film shell around soft contents for e-commerce picking and induction.

Also called poly bag, polybag, bagged garment or apparel polybag.

How is the deformable polybagged apparel item modeled?

The bag is a thin film shell sealed on three sides with a fold-over flap, sized to the garment inside. The film is light and slippery, and creases where the garment underneath bends.

The garment is a folded cloth block that fills the bag, so the package bends in the middle when lifted from one end, the way real polybagged apparel does on a conveyor.

Which parts of the deformable polybagged apparel item deform?

Film bag
Thin, slippery shell that wrinkles and creases
Folded garment
Soft fill that bends and sags inside the bag

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.
  • Cloth. A triangle surface with stretch, shear and bending stiffness and a thickness. Used for towels, sheets and garments.

Where is it used?

  • Piece picking from a tote
  • Induction onto a sorter
  • Suction grasp on film

Industries: Logistics, Retail

Questions

Will a suction cup seal on the film?

The film is a thin shell with its own stiffness, so it wrinkles under a cup the way real film does. That is what makes polybag grasps fail, and why it is modeled rather than drawn on a box.

Which simulators does the deformable polybagged apparel item 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.
