Plastic! Please forgive me if I’m asking a heresy but wouldn’t accomplish the same purpose, which is to save models from dust? They should be acid-free, right? Or not? They seem sturdier than acid-free cardboard boxes.
Plasticizers are typically added to make rigid PVC flexible. These can leave or outgas from PVC over time. I would not consider it archival if that is a real consideration. It may be fine for protecting from dust. Thanks, Doug
