Water Vapor Barrier Testing for Chemical Product Packaging

For chemical products like pharmaceuticals and powdered cleaning agents, moisture can be a silent enemy, causing degradation, clumping, or reduced efficacy. Rigorous water vapor barrier testing of packaging materials is crucial. This testing ensures packaging can shield sensitive contents from humidity and maintain their quality throughout their shelf life.

Pharmaceuticals, often highly sensitive to moisture, demand robust protection. Blister packs, with their individual sealed compartments and foil backing, provide an excellent moisture barrier. Powdered cleaning products also benefit from moisture-resistant packaging. Caking or clumping due to moisture ingress can render these products less effective or even unusable.

Moisture-resistant pouches offer a versatile and often cost-effective packaging option. These pouches utilize specialized films and laminates to create a barrier against moisture. For example, a three-layer pouch might consist of an outer layer for printability and durability, a middle layer of aluminum foil for a superior moisture barrier, and an inner layer of polyethylene for heat sealing and product compatibility. Such pouches are suitable for single-dose pharmaceuticals, powdered supplements, or even smaller quantities of cleaning agents. Testing the barrier properties of the materials helps maintain product quality and prevents moisture-related degradation.

Several standardized methods exist for evaluating a material's water vapor transmission rate (WVTR). These tests, often conducted under controlled temperature and humidity conditions, measure how much moisture permeates the packaging over time. Common standards include ASTM F1249 and ASTM E96. The results help manufacturers select the optimal packaging to protect their products.

Labthink C306H Water Vapor Transmission Rate Test System is designed and manufactured based on infrared sensor method and conforms to the requirements of ASTM F1249 and ISO 15106-2. This instrument can be used to measure the water vapor transmission rate of barrier materials with high and medium moisture barrier properties with a wide testing range and high testing efficiency. C306H is applicable to determination of water vapor permeability of plastic films, sheeting, paper, packages and other relative packaging materials in food, pharmaceutical, medical apparatus, consumer goods, photovoltaic and electronic industries, etc.

Labthink C360H Water Vapor Transmission Rate Test System is designed and manufactured based on the gravimetric determination method and conforms to the requirements of ASTM E96.

Choosing the right packaging and validating its performance through water vapor barrier testing is essential for ensuring the safety and efficacy of chemical products. By understanding the moisture sensitivity of their products and employing appropriate packaging solutions, manufacturers can safeguard their formulations and deliver quality to consumers.
