1. Introduction
Pharmaceutical packaging serves as the primary barrier between the drug formulation and the external environment, protecting it from contamination, moisture, oxygen, and other detrimental factors. Plastic packaging, in particular, has gained significant popularity due to its versatility, cost-effectiveness, and ease of processing. This paper explores the latest advancements in plastic packaging materials and technologies used in the pharmaceutical sector and examines the challenges associated with their application.
2. Advancements in Pharmaceutical Plastic Packaging
2.1 Materials Innovations
Recent years have witnessed the development of advanced plastic materials with enhanced barrier properties. For instance, multi-layer structures combining different polymers, such as ethylene vinyl alcohol (EVOH) and polyethylene terephthalate (PET), offer superior protection against moisture, oxygen, and gases. Additionally, active packaging materials embedded with antioxidants, desiccants, or adsorbents further extend the shelf life of sensitive drugs.
2.2 Technological Enhancements
Technological advancements have facilitated the production of plastic packages with intricate designs and features. Injection molding, blow molding, and thermoforming techniques have been refined to create tamper-evident, child-resistant, and elderly-friendly packaging solutions. Moreover, the integration of radio-frequency identification (RFID) tags and near-field communication (NFC) technology enables traceability and authentication of pharmaceutical products.
2.3 Sustainable Practices
The pharmaceutical industry is increasingly adopting eco-friendly packaging solutions to minimize environmental impact. Biodegradable and compostable plastics derived from renewable resources, such as polylactic acid (PLA) and polyhydroxyalkanoates (PHA), are gaining traction. Additionally, recycling initiatives and the use of post-consumer recycled (PCR) plastics are being promoted to reduce waste.
