Map the real distribution route
When a Carton Needs More Than a Simple Drop Test is best approached as a measurable packaging decision, not a visual preference. Parcel networks, pallets, ocean freight and local delivery expose packaging to different shocks, vibration, compression and climate. Define the expected route, handling points and storage conditions before choosing a test. A generic drop height alone does not represent the complete journey.
Protect glass and decoration separately
Dividers prevent glass-to-glass contact, while sleeves or films may protect coated surfaces from abrasion. Check that protective materials do not mark soft coatings or transfer odour. Carton strength, void control and top-load performance matter more as bottles become heavier.
Verify the production pack
Transport trials should use the intended bottle, cap, decoration, inner protection, carton quantity and pallet pattern. Retest when a material, supplier, bottle weight or carton configuration changes. Record gross weight and dimensions because these data affect both freight quotations and safe handling.
