How to Choose the Right Adhesive Tape and Seal for Your Postal Boxes
Tape types, eco alternatives, and sealing methods for secure, professional postal box packaging.
Tape types
Quick answer
Paper tape or water-activated tape are the best choices for postal boxes. Both are fully recyclable with the box, create strong bonds, and look professional. Water-activated tape is the strongest and most tamper-evident but requires a dispenser. Paper tape works with standard dispensers. Avoid plastic tape if your brand values sustainability, as customers must remove it before recycling.
Eco-friendly options
Can be left on the box when recycling. No separation needed by the customer.
Creates a bond stronger than the board itself and is fully biodegradable.
Plastic tape must be removed before recycling. Many customers do not bother, contaminating the recycling stream.
Crash lock bases, tuck-top closures, and peel-and-seal strips eliminate external tape entirely.
Packaging efficiency: packing guide or flat-pack vs ready-to-go.
Security sealing
For high-value items, tamper-evident sealing adds security. Water-activated tape tears the board if removed, showing evidence of tampering. Custom-printed tape with your logo also provides a visual security indicator and brand reinforcement.
