Primary packaging refers to the pharmaceutical product’s material, including bottles, blister packs, vials, syringes, ampoules, sachets, blister packaging, and unit dose packaging. On the other hand, secondary packaging refers to the exterior packaging of the primary packaging that helps differentiate the packages and protect or label the drug products inside.
Tertiary packaging is used to group larger quantities or for the bulk transportation of pharmaceutical products from point A to point B. Moreover, it facilitates the bulk handling, transportation, and protection of various sales units or secondary packaging while grouping everything into unit loads during transit. The customer very rarely sees this kind of packaging.
