Types of Medical Packaging — How Formosa Flexible Packaging Corp Helps You Master PTP Packaging and Moisture Protection for Pharmaceuticals
I. Why Do Pharmaceuticals Require Such Strict Packaging Standards?
1-1 High Standards in the Medical and Pharmaceutical Industry
Packaging requirements in the pharmaceutical field are far stricter than those for general consumer goods.Beyond protecting appearance and transport safety, they directly impact drug efficacy and patient safety.For tablets, capsules, injectables, and medical devices, packaging serves as the final protective barrier throughout the product lifecycle.Any oversight in the packaging process can reduce drug stability or create safety risks.。1-2 Why Are Moisture, Light, and Contamination Protection So Critical?
Pharmaceutical products are highly sensitive to humidity, light, and contamination.Even trace amounts of moisture can break down active ingredients, while light accelerates oxidation reactions.High-quality packaging must provide excellent moisture resistance, barrier performance, and light shielding,ensuring that medicines remain stable from production to end use.Technologies such as PTP blister packaging, cold-form aluminum foil, and multi-layer barrier films are key solutions widely used for high-grade pharmaceutical moisture-proof applications.1-3 Formosa Flexible Packaging Corp’s Professional Strengths

III. Why Packaging Affects Drug Stability and Market Approval
3-1 The Critical Link Between Packaging Function and Drug Stability
The performance of pharmaceutical packaging not only protects against external factors—it directly impacts drug efficacy and safety.For example, probiotic capsules with insufficient moisture barriers may lose viability before reaching the market,and light-sensitive drugs without proper light shielding can degrade during transport or storage.
Therefore, moisture-proofing, oxygen resistance, light protection, and heat stability are not just data points—they are essential to maintaining therapeutic effectiveness.
3-2 Regulatory Requirements in Major Global Markets
Stringent packaging regulations apply across all major pharmaceutical markets:- European Union (EMA)：Primary packaging materials must pass EMA safety assessments.
- United States (FDA)：Drug Master File (DMF) submission required to trace material sources and manufacturing processes.
- Japan (PMDA / MHLW)：Chemical stability and extractables/leachables of contact materials are regulated.
- China (NMPA)：Requires formal registration and technical evaluation for all pharmaceutical packaging.
3-3 Certification and Testing Procedures
Formosa Flexible Packaging Corp is well-versed in global pharmaceutical packaging regulations,and several of our products have already obtained NMPA registration and DMF certification.Comprehensive testing reports can be provided upon request, including:Water Vapor Transmission Rate (WVTR)、Oxygen Transmission Rate (OTR)、Heat seal strength, burst resistance, and microbiological testing，every batch is verified to meet the highest standards of compliance, safety, and performance.
