Oxygen Permeability

Oxygen permeability refers to the ability of a material, like plastic or packaging, to allow oxygen molecules to pass through it. This property is important for packaging perishable products, as high oxygen permeability can lead to faster spoilage due to oxidation, while low permeability helps preserve freshness. It’s measured by how much oxygen can cross a given area of the material over a certain time under specific conditions. Think of it as how "breathable" the material is for oxygen, affecting the shelf life and quality of food, pharmaceuticals, or other sensitive items.
