Can smell go through plastic?

Yes, smells can pass through plastic because plastic is porous at a molecular level, allowing tiny odor molecules (volatile compounds) to slowly permeate the material, though it's a slow process and the rate depends on the plastic type, thickness, and the specific smell. That's why you can often smell food through plastic bags or containers, and why strong smells like garlic can get "stuck" in plasticware.

Yes, plastic readily absorbs smells because it's porous at a microscopic level, allowing odor-causing molecules (especially oily ones from food) to seep in and get trapped, leading to lingering odors, particularly with strong foods or when hot food is placed in them.
