What type of materials are considered barrier films in drug packaging?

High barrier films are specifically engineered to limit the permeation of moisture as well as other environmental factors that can compromise the integrity of drug packaging. These materials play a crucial role in ensuring the longevity and effectiveness of pharmaceutical products by creating a protective barrier that maintains the stability and potency of the drugs contained within.

Moisture can significantly affect the quality of drugs, potentially leading to degradation or compromised efficacy. Therefore, selecting materials that provide high barrier properties is vital in the pharmaceutical industry, particularly for products that are sensitive to moisture. By utilizing high barrier films, manufacturers can help ensure that medications remain effective and safe for the duration of their intended shelf life.

In contrast, materials with zero moisture barriers, thin films that allow moisture to escape, or biodegradable materials do not provide the necessary protection against moisture and other environmental factors, which can jeopardize the quality and safety of pharmaceuticals over time. Hence, the focus is on high barrier films for optimal product protection in drug packaging.
