Certain packaging formats create the risk of label components, like inks and adhesives, migrating through the container surface and potentially interacting with the drug product.
Low migration labels are designed to help protect product safety and reduce this risk.
How package materials influence migration risk
The need for low migration labeling depends on both the drug product and the packaging substrate.
Glass is an effective functional barrier, but plastic containers are more sensitive. They are more permeable and often require additional assessment. Liquid formulations are especially susceptible to migration.
