Product Information
Our corrugated pocket boxes are a smart, protective alternative to standard mailers when you need extra strength for flat or delicate items. Manufactured from recycled E flute corrugated board, these boxes are lightweight yet rigid, helping to prevent bending, crushing, or transit damage.
Each pocket box includes a hot melt peel & seal strip for fast packing and secure closure, plus an easy-open red ripper strip for a clean customer unboxing experience. Often referred to as Amazon-style boxes, they’re ideal for shipping books, magazines, DVDs, CDs, documents, and other similar flat products.
Key Benefits
- Strong protective board: rigid E flute construction resists bending in transit
- Recycled & recyclable: made from 100% recycled corrugated material
- Peel & seal closure: quick, secure sealing with no tape required
- Ripper strip opening: simple tear-open access for the recipient
- Flat or expandable use: PiP-friendly sizing depending on contents
