Understand the pros, cons, and compliance factors when choosing between two common pharmaceutical packaging methods.
Stretch Banding vs. Shrink Wrapping in Pharma Packaging
Choosing the best packaging method in the pharmaceutical industry is crucial. Both stretch banding and shrink wrapping have their pros and cons. Understanding these can help you make an informed decision.
What Is Stretch Banding?
Stretch banding is a modern packaging method. It uses tensioned film to secure grouped items without applying heat. This characteristic is particularly beneficial in the pharmaceutical industry. Product sensitivity and packaging integrity are critical for effective distribution.
The process of stretch banding involves wrapping a narrow film band around items. Examples include cartons or blister packs. After wrapping, the band is sealed using ultrasonic welding or adhesive. This method provides secure bundling and tamper evidence.
Typical use cases in pharmaceutical packaging:
Bundling medicine cartons for distribution
Wrapping vials or ampoules in trays
Grouping blister packs for secondary packaging
What Is Shrink Wrapping?
Shrink wrapping is another popular packaging method. It involves enclosing products in shrink film. Then, heat is applied via tunnels to shrink the film around the package. This method creates a tight, transparent seal. It is often used for display multipacks or logistical bundling.
Common pharma applications include:
Multipack formats of over-the-counter medications
Tamper-evident overwraps for prescription packs
Bulk transit packaging
Key Differences for Pharmaceutical Packaging
🔥 Heat Sensitivity
Stretch Banding: ✅ Safer for biologics and temperature-sensitive drugs, as no heat is used.
Shrink Wrapping: ⚠️ Involves heat tunnels that may affect heat-sensitive APIs or packaging materials.
⚡ Energy Consumption & Sustainability
Stretch Banding: ✅ Energy-efficient since no heat tunnels are used. This results in a lower carbon footprint.
Shrink Wrapping: ❌ Uses high energy due to heat-sealing and tunnels.
Did you know? Stretch banding can reduce energy use by up to 70%.
⚙️ Speed and Automation
Stretch Banding: ✅ High-speed systems with flexible inline integration. This is ideal for batch changeovers.
Shrink Wrapping: ⚠️ While fast, it is less adaptable due to fixed tunnel configurations.
💷 Material Cost Comparison
Stretch Banding: ✅ Requires up to 70% less film, which reduces both plastic usage and cost.
Shrink Wrapping: ❌ Full enclosure means more film is needed, resulting in a higher per-pack cost.
Compliance and Regulatory Requirements
Both methods can meet the guidelines set by MHRA, EU, and FDA concerning tamper evidence and safety. However, stretch banding offers several compliance-friendly advantages:
Clear label visibility for serialization and batch tracking.
Easier alignment with UK and EU sustainability targets.
Lower Scope 2 emissions for ESG reporting.
Final Verdict: Which Is Right for Your Line?
Considering the needs of pharmaceutical manufacturers is key. Factors like cost, sustainability, and product safety should be prioritized. Stretch banding generally emerges as the superior option. This is especially true when managing heat-sensitive products or operating in high-throughput environments.
