Types are classified into primary and secondary packaging. Primary packaging (60% share) includes direct-contact systems like blister packs, vials, and syringes, prioritizing material compatibility, dosage precision, and patient safety. Innovations in smart packaging (e.g., RFID-enabled blister packs) and biocompatible polymers are key growth drivers here. Secondary packaging (40%) encompasses cartons, tamper-evident seals, and labeling, emphasizing brand visibility, environmental sustainability, and regulatory compliance (e.g., serialization). While primary packaging remains core to functional requirements, secondary packaging gains traction through eco-friendly designs and digital integration. This market taxonomy reveals how material science advancements and regulatory frameworks differentially impact each type, with primary packaging anchoring market size and secondary packaging amplifying value through added functionalities.
