A blister card encloses individual doses in formed pockets sealed with lidding material; a multi-dose bottle holds the full pack count behind a shared closure. Selecting between the two formats depends on dose count, patient or clinical dispensing workflow, product protection requirements and downstream cartoning interfaces.
| Decision point | Blister card | Multi-dose bottle |
|---|---|---|
| Dose access | Individual pockets opened one dose at a time | Shared container and reclosable cap |
| Product-contact components | Forming web and sealed lidding foil | Bottle body, liner, closure and any desiccant |
| Identification | Printed lidding and outer carton; per-cell coding when perforated for unit-dose use | Primary container label and outer carton where used |
| Output units | Cards per minute for a defined cavity count | Bottles per minute for a defined fill count |
Specify the operating and protection conditions first
Start from the course length, the intended opening method and the regulatory requirements for the destination market. Under US 21 CFR 211.94, drug product containers and closures must protect against foreseeable external factors in storage and use without reactive, additive or absorptive effects. Child-resistant and tamper-evident features follow the applicable market standards and must be verified on the complete pack configuration.
For the forming-web decision within a blister pack, compare PVC, PVDC-coated film and cold-form aluminum against the product’s moisture-barrier requirement and formed-and-sealed pack stability evidence.
Connect the primary pack to downstream operations
Both blister cards and bottles serve as primary packages under the definitions in Primary, secondary and tertiary packaging. Either format can be loaded with a patient leaflet into an outer carton, as covered in Pharmaceutical cartoning. Use the URS checklist to record primary-pack dimensions, count per pack and inspection checks before evaluating line equipment.
