ASTM E96 Plastics Packaging Moisture Transmission Testing
The ASTM E96 standard is a critical tool used to determine the rate at which moisture permeates through packaging made from plastics. This service is particularly important for ensuring that packaging materials are effective in protecting products from moisture damage, especially in environments where humidity levels fluctuate. Understanding how moisture can penetrate these materials helps manufacturers design more reliable and efficient packaging solutions.
Moisture transmission testing assesses the barrier properties of packaging films and containers using a gravimetric method. The test involves placing a known weight of water on one side of a specimen while maintaining controlled conditions on the other side, typically at 100% relative humidity. Over time, moisture diffuses through the material, causing a change in weight that can be measured to determine the permeability.
The ASTM E96 test is widely used across various industries including food and beverage, pharmaceuticals, electronics, and consumer goods. It ensures that packaging not only meets regulatory requirements but also performs optimally under real-world conditions. By conducting this test, manufacturers can identify potential flaws in their design early on, thereby reducing the risk of product spoilage or contamination.
The process involves several key steps:
- Specimen Preparation: Specimens are cut to standard dimensions and conditioned according to ASTM E96 specifications. This ensures that all samples start in a consistent state before testing begins.
- Humidity Control: A controlled humidity chamber is used to maintain the specified conditions on one side of the specimen while allowing free passage of water vapor through it.
- Weighing: Initial and final weights are recorded periodically over a set period, usually 72 hours. The difference in weight indicates how much moisture has passed through the sample.
- Data Analysis: Moisture transmission rates (MTRs) are calculated based on the change in mass over time. These values help assess the effectiveness of different packaging materials.
This testing method is essential for industries where product integrity depends heavily on maintaining proper moisture levels within their packages. It allows companies to make informed decisions about material selection, thickness, and design optimization. By adhering to ASTM E96 standards, manufacturers can ensure that their products remain safe and effective throughout storage and distribution.
Industry Applications

The ASTM E96 test is not only applicable to single-layer films but also multi-layer structures. Multi-layer packages often combine different materials with varying moisture barrier properties, making them ideal for this type of testing. The insights gained from these tests are crucial in optimizing the design and performance of packaging solutions across various sectors.
International Acceptance and Recognition
