Protecting Product Integrity with Advanced Barrier Performance Evaluation
At METS Lab, we provide specialized Barrier Property Testing services to evaluate the ability of packaging materials to resist the passage of gases, moisture, light, and aroma. These properties are critical in determining product shelf life, quality preservation, and regulatory compliance—particularly in food, pharmaceutical, cosmetics, and electronics packaging.
Barrier performance directly impacts how well a package can protect its contents from environmental influences such as humidity, oxygen, and UV exposure, all of which can degrade sensitive products. Our barrier testing solutions are designed to meet industry standards and support packaging development, validation, and quality control.
Why Barrier Property Testing Is Critical
Effective barrier properties help:
- Extend shelf life by limiting exposure to oxygen and moisture
- Maintain product flavor and aroma
- Prevent microbial growth and spoilage
- Protect from oxidation and degradation
- Ensure regulatory and market compliance
- Optimize packaging material selection and design
With increasing demands for sustainable and lightweight materials, it’s essential to validate barrier performance without compromising protection.

Our Barrier Testing Capabilities
Water Vapor Transmission Rate (WVTR)Standards: ASTM F1249 / ISO 2528
WVTR testing measures the amount of moisture that passes through a packaging material over time. This is especially crucial for products sensitive to humidity, such as dehydrated foods, pharmaceuticals, and electronics. Using gravimetric or sensor-based methods, we help you determine the ideal material for your moisture control requirements.

Oxygen Transmission Rate (OTR)Standards: ASTM D3985 / ISO 15105
Oxygen exposure leads to oxidation, spoilage, and reduced potency in oxygen-sensitive products like meats, dairy, and certain medications. Our OTR testing determines how much oxygen permeates through a film or container, helping you choose high-barrier solutions to extend product life and maintain quality.

Gas Permeability Testing (CO₂, N₂, etc.)
Aroma, Light, and UV Barrier Testing
Products like coffee, spices, pharmaceuticals, and cosmetics are highly sensitive to odors, UV light, and aroma loss. Our tests assess how well a material blocks undesirable odor migration or exposure to UV rays that can degrade active ingredients or cause photo-reactive changes.
We simulate real-world conditions to help manufacturers choose the right packaging solutions for aroma retention, light protection, and sensory stability.
