5 Professional Steps for Optimal Protection

1. Item Preparation
   • Wrap sharp edges with foam corners (e.g., phone cases)
   • Place small items in anti-static bags first
2. Select Mailer Size
   • Item should occupy 70% of internal space
   • Allow 2cm clearance on all sides
3. Insertion Technique
   • Place heaviest side against bubble layer
   • Position bubbles facing inward for direct cushioning
4. Sealing Protocol
   • Peel adhesive strip fully
   • Press firmly along entire flap (10N pressure)
   • Reinforce seams with 5cm tape on each end
5. Labeling Best Practices
   • Apply label over seam tape (prevents peeling)
   • Cover with transparent tape if shipping in rain

Pro Tip: For >500g items, use double-layer mailers with cross-pattern taping!
