Sustainability is becoming a top priority in pharmaceutical packaging.

By using the right materials and simplifying design, companies can reduce waste while maintaining product protection. Two key materials leading the way are polypropylene (PP) and polyethylene terephthalate (PET).

Why PP and PET Matter

• Recyclable Materials: PP and PET can be recycled, so used packages turn into new products instead of waste.
• Lightweight Strength: They are strong yet lightweight, so less material is needed, and less fuel is used in transport, reducing emissions.
• Durability: They are durable, preventing damage or spoilage of medicines and avoiding product waste.

Biodegradable Additives: A Smarter Layer of Sustainability

One innovation is biodegradable additives – special ingredients added to plastic that help it break down faster after use. When packaging with these additives is thrown away, microbes can "eat" the plastic and turn it into harmless natural substances like water and gas within a few years. This prevents long-term plastic buildup in landfills.

Design for Recycling Matters

Recyclability isn’t just about the material—it’s about how a package is built. Traditional closures often use multiple plastics, liners, and seals that make recycling difficult. Simpler designs using fewer, compatible materials improve outcomes.

For example, some packaging solutions are intentionally designed with lesser parts. Each component is fully recyclable on its own, with no extra liners, foils, or mixed materials. This thoughtful design supports easy separation and recycling while maintaining safety and compliance.
