OTR and WVTR Testing Lab
In today’s packaging industry, the durability and barrier performance of materials are key to preserving product quality—particularly for food, pharmaceuticals, and sensitive electronics. Two critical indicators of packaging effectiveness are Oxygen Transmission Rate (OTR) and Water Vapour Transmission Rate (WVTR).
Sima Labs offers precise and standardized OTR and WVTR testing services to help ensure your packaging meets regulatory and performance standards. Our analyses support longer shelf life, enhanced product stability, and protection against environmental factors.
Oxygen Transmission Rate (OTR)
OTR quantifies the amount of oxygen that permeates through a packaging material over time. Oxygen exposure can compromise product freshness, potency, and safety. At Sima Labs, we conduct OTR testing in accordance with ASTM D3985, delivering accurate insights into material permeability.
Why OTR Testing Matters:
Food Packaging: Prevents oxidation and spoilage, maintaining taste and nutritional value.
Pharmaceuticals: Ensures efficacy by minimizing oxygen exposure in sensitive drugs.
Other Industries: Protects electronics, cosmetics, and chemicals from oxygen degradation.
Water Vapour Transmission Rate (WVTR)
WVTR measures how much moisture vapour passes through packaging over time. Excess moisture can spoil food, damage electronics, or destabilize pharmaceuticals. Our testing follows the ASTM F1249 standard for precise WVTR analysis.
Why WVTR Testing Matters:
Food: Keeps dehydrated or dry foods crisp, safe, and mold-free.
Pharma: Prevents moisture-related degradation of sensitive formulations.
Electronics & Materials: Reduces risk of corrosion or performance failure due to humidity.

Safeguarding Health, Ensuring Quality – One Test at a Time.
In modern packaging, controlling oxygen and moisture transmission is vital for preserving product quality, especially in food, pharma, and electronics.
Sima Labs offers precise OTR and WVTR testing using ASTM D3985 and ASTM F1249 standards to help you meet regulatory requirements and extend shelf life.
OTR (Oxygen Transmission Rate):
Measures oxygen permeability to prevent oxidation, spoilage, and potency loss.
Applications: Food freshness, pharmaceutical stability, electronics protection.
WVTR (Water Vapour Transmission Rate):
Quantifies moisture permeation to avoid mold, degradation, or corrosion.
Applications: Dry food preservation, moisture-sensitive drugs, electronic reliability.
