Factors to Consider While Package Development (Second Package Development Factor – Product Package Compatibility)

Compatibility with the packaging is developed independently for stability, which evades confusion between the stability issue (of the formula) and problems due to inadequate packaging.

 When testing a product for shelf-life and compatibility, the packaging should be considered a significant factor. While the product itself may have a relatively stable shelf-life, the same compatibility may not be observed in its final packaging when tested in glass or another temporary package.

 It is significant to verify that the package chosen will offer the protection needed to prevent this as it may lead to unpleasant changes in the product. Demonstrating how the product will react to certain conditions while in the package will help determine what conditions are best for your product's proper storage. 

 For instance, products that degrade with exposure to light or moisture will need to store in such a way that will prevent them from exposure unless the packaging can demonstrate sufficient protection from those conditions. Easily damaged packages - must be avoided, as this can cause a product to spoil from microbial or chemical changes.

 Thus, it is essential to run compatibility testing in the packaging intended for marketing due to interactions (that may occur) between the package, the product, and the environment.
