Matching Packaging Materials to Drug Dosage Forms
Not every packaging material option is perfect for all pharmaceutical products. Each product requires specific packaging materials. This is largely due to the characteristics of the medicine and the properties of the packaging material.
A critical regulatory requirement in pharmaceutical packaging is Child-Resistant Senior-Friendly (CRSF) design. These solutions ensure packaging is secure enough to prevent accidental ingestion by children while remaining accessible and easy to open for elderly patients.
Now we are going to state the characteristics of each type of product. Then give you a few packaging options that would suit them.
1. Tablets and Capsules
- Primary packaging: Glass bottles, blister packs
- Secondary packaging: Paperboard cartons
These are among the most common forms of pharmaceuticals, known for their convenience.
Tablets are usually composed of powders compacted into solid forms, while capsules consist of medicines enclosed in gelatin or vegetarian shells. Both need packaging that preserves their integrity and potency.
Bottles and blister packs check all the boxes if you are looking for primary packaging to safeguard tablets and capsules.
Besides protection, they provide tamper-evident features to assure your consumers of the product’s authenticity. This sense of security fosters trust between your business and customers. And for secondary packaging, most companies prefer paperboard cartons for their versatility and eco-friendliness.
2. Liquid Formulations
- Primary packaging: Plastic bottles or glass bottles
- Secondary packaging: Corrugated boxes or cardboard boxes
Syrups, suspensions, and other liquid formulations require packaging materials that ensure product stability and safety.Typically, these formulations contain active ingredients that may degrade when exposed to light or oxygen.
The packaging materials must offer protection against these elements. So, plastic bottles, especially those made from high-density polyethylene or amber glass, are the most commonly used due to their ability to block light and oxygen penetration.
But when it comes to secondary packaging, you should focus on materials that can act as a barrier against moisture, temperature fluctuations, and physical damage.
Corrugated boxes or cardbCorrugated boxes or cardboard cartons are the most common. They provide a surface for important labeling information to ensure clear communication to consumers. This, plus protection, makes boxes and cartons ideal as secondary packaging for liquid formulations.
3. Injectable Products
- Primary packaging: Glass vials or ampoules
- Secondary packaging: Cartons
These products often contain sensitive formulations that must be protected from contamination and degradation. For instance, vaccines demand packaging that prevents exposure to light, oxygen, and moisture to maintain their potency.
Glass vials and ampoules are generally used as the primary packaging because of their inert nature and ability to withstand sterilization processes. Cartons further offer protection during storage and transportation.
But the most important requirement here, other than protection, is compliance with regulatory standards by the FDA and EMA.
