🚚 Ever wondered why a heavy-duty double-wall case still fails during transit? 🤔
At Garthwest, we believe that context beats thickness every time. When it comes to corrugated packaging, failure often isn’t about strength; it's about the design for the journey.
Here are 4 must-dos when specifying transit packaging to ensure your products arrive safely:
1️⃣ Design for the journey – not just the warehouse
Different transport modes (sea freight, air cargo, courier networks) introduce unique stress patterns. Start with the distribution map, not just the board grade!
2️⃣ Engineer for compression & humidity (Sea Freight)
Long container dwell times and high humidity can weaken stacking strength over time. Selecting the right flute combination and liner quality can protect against moisture-related issues.
3️⃣ Balance stiffness and weight (Air Freight)
Air transit brings vibration and pressure variations. Choosing the right flute profile delivers stability while keeping weight costs in check — strength-to-weight ratio matters!
4️⃣ Prioritise impact resistance for the last mile
With parcel networks facing drops and knocks, liner performance and impact resistance can be more crucial than stacking strength alone.
🔑 The takeaway?
Instead of asking for a “thicker” box, ask for the right flute profile and liner combination tailored to the actual stresses your packaging will encounter.
At Garthwest, we align board specifications with real-world distribution conditions, protecting your product, reputation, and margins.
