Why Packaging Is a Compliance Issue Too
Packaging touches the product for its entire shelf life. Building on the child-resistant packaging and stability content discussed elsewhere in this publication, the materials themselves can affect potency, safety, and compliance.
What Migration Means
Migration is the transfer of substances between packaging and product. Plasticizers, inks, adhesives, or residues can move into the contents, and cannabinoids and terpenes can move the other way, adsorbing into the packaging and lowering measured potency.
Common Packaging Materials
Glass. Largely inert, with low interaction, though it offers little light protection unless tinted.
Plastics. Different resins behave differently with cannabinoids and oils, so compatibility testing matters.
Metal and liners. Coatings and liners can interact with acidic or oily contents.
Testing to Consider
- Potency over shelf life in the final package, not only in bulk
- Compatibility of the packaging with the formulation
- Evidence that food contact materials meet applicable standards
What Buyers Should Ask
Ask for packaging specifications, compatibility data, and shelf-life results in the actual container.
