barrier properties
Resistance to penetration
Barrier properties describe how well a material resists the passage of substances through it—gases, liquids, moisture, or light.
The term appears most often in packaging and materials science: The film's barrier properties keep oxygen from reaching the food.
Good barrier properties mean low permeability; poor barrier properties mean substances pass through easily.
- impermeabilityResistance to passage
- thicknessDepth of material
- corrosion resistanceImmunity to chemical degradation
- hydrophobicityResistance to wetting
- waterproofingMaking impervious to moisture
