📢 Blog Post Alert! In our latest blog post, Mark reviews why performance testing matters for pharmaceutical products and how USP Testing ensures product quality.

In the pharmaceutical industry, packaging is more than a container—it is a critical component of product quality, stability, and patient safety. USP, Containers—Performance Testing, establishes standardized methods for evaluating the moisture v***r transmission characteristics of pharmaceutical packaging systems. These tests help manufacturers verify that their packaging adequately protects products from environmental conditions that could impact quality, potency, or shelf life.

📢 Blog Post Alert - "Why USP Testing is Becoming Mandatory for Pharmaceutical Packaging."

In our most recent blog post, Mark addresses the new era of regulatory scrutiny pharmaceutical companies will experience regarding plastic packaging systems used for drug products. The revised USP chapters and USP became official on December 1, 2025. These new chapters require pharmaceutical companies to demonstrate that their packaging materials and systems are suitable for their intended use and do not compromise product quality or patient safety.

USP Testing - Spectral Transmission Testing

Moisture isn’t the only variable that affects product stability. Light exposure, especially UV and visible wavelengths, can degrade certain formulations over time. In some cases, packaging that performs well against moisture still doesn’t provide enough protection from light.

USP includes spectral transmission testing to measure the amount of light that passes through a container. This helps determine whether the packaging provides the level of protection the product requires.

USP Testing - MVTR and Packaging Performance

MVTR answers a simple question: how much moisture is getting through the container, and is that acceptable for this product?

Even small amounts of moisture can affect stability over time. That’s why MVTR matters most with moisture-sensitive products, especially solid and liquid oral dosage forms.

If that comprehensive testing isn’t conducted, it usually shows up later as a packaging issue you have to go back and fix, which can slow timelines and force rework.

USP Testing - What Testing Actually Tells You

USP isn’t optional in many cases. It helps prevent the wrong packaging choice by showing how well the container
protects the product from moisture over time.

At its core, it measures the moisture v***r transmission rate (MVTR), which indicates how much moisture can pass through a container under controlled conditions.

From that, you can answer three things:

• Whether the packaging provides enough barrier protection for the product
• Whether it will maintain stability over its intended shelf life
• Whether it’s the right container to move into stability studies or to finalize your submission

Instead of relying on assumptions or past use, you have clear data to make the call and back it up when it’s questioned.
