What key parameters must be considered when selecting primary packaging for a product?

When selecting primary packaging for a product, compatibility and safety are critical parameters that need careful consideration. Compatibility refers to ensuring that the packaging material does not interact adversely with the product it contains. This is crucial because inappropriate material can lead to chemical reactions, which could affect the product's integrity, stability, and performance.

Safety is another paramount concern, as it encompasses the potential hazards the packaging may pose during handling, storage, and use. This includes evaluating whether the materials used in the packaging leach harmful substances into the product or if they can withstand various environmental conditions without degrading.

While volume and material are important aspects, they are more related to logistical considerations than to the direct impact on the product's safety and stability. Evaluating safety and efficacy primarily addresses the product itself rather than the suitability of the packaging. Therefore, focusing on compatibility and safety ensures that the primary packaging protects the product adequately while posing no risk to users or the environment.
