Our corrugated pocket envelopes 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 envelopes are lightweight yet rigid, helping to prevent bending, crushing, or transit damage.

Each pocket envelope 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 mailers, 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
