Introduction to Water Vapor and Oxygen Transmission Rate Tests
Controlling moisture and oxygen in packaging is crucial for maintaining product quality and longevity. Water Vapor Transmission Rate (WVTR) and Oxygen Transmission Rate (OTR) tests are essential for assessing the barrier properties of packaging materials.

Importance of WVTR and OTR Tests
Moisture and oxygen can degrade packaged goods, leading to spoilage, clumping, decay, oxidation, discoloration, flavor loss, and reduced shelf life. Effective barrier properties in packaging are vital across various industries:
  • Food Packaging: Extends shelf life by minimizing spoilage.
  • Pharmaceuticals: Safeguards drug efficacy by preventing degradation.
  • Medical Devices: Ensures sterility, crucial for patient safety.
  • Electronics: Protects sensitive components from humidity.

Water Vapor Transmission Rate (WVTR)
WVTR measures the rate at which water vapor passes through a material, expressed in grams per square meter per day (g/m²/day).
  • Dry Foods: Require very low WVTR, often below 1 g/m²/day.
  • Pharmaceuticals: Need very low WVTR to maintain potency.
  • Building Materials: Use WVTR to evaluate vapor barrier performance.

Oxygen Transmission Rate (OTR)
OTR measures the rate at which oxygen permeates a material, measured in cubic centimeters per square meter per day (cc/m²/day).
  • Food Packaging: Requires very low OTR, often below 10 cc/m²/day.
  • Pharmaceuticals and Medical Devices: Need extremely low OTR for stability and sterility.
  • Beverages: Use low OTR to maintain carbonation.

Testing Standards and Equipment
WVTR and OTR tests are conducted under controlled conditions, following standards such as ASTM F1249, ASTM E96 (WVTR), and ASTM D3985 (OTR). The Labthink C406H Test System uses a Coulometric oxygen sensor and infrared water vapor sensor, designed according to ASTM and ISO standards, to provide high precision and efficiency in testing high and medium gas barrier materials.

Conclusion
Manufacturers select materials based on barrier properties, considering product sensitivity, shelf-life, and environment. WVTR and OTR tests are vital for quantifying packaging barrier properties, protecting products from moisture and oxygen, and ensuring quality and reliability. Understanding and utilizing these tests allows manufacturers to deliver safer, longer-lasting products.
