The microplastics in a product don’t have to originate in a product’s final packaging. Things like airborne particles on the production line, filaments from filters and cleaning equipment, manufacturing swarf, and cleaning processes that are oriented to killing small things with heat / UV / chemistry rather than filtering tbem out is probably more of the answer than leaching and degradation.

Understood, but the article specifically said: "anything stored in plastic bottles, plastic wrap, or cans/cartons lined with plastic".
