Long-format Honeycomb Paper Mailer and Padded Paper Envelope with Self-adhesive Seal and 3-layer Structure

The Long Honeycomb Paper Mailer is an extended-format shipping envelope designed for long, narrow items such as rolled posters, fabric swatches, documents, and small textiles. Made from 100% recycled kraft paper with a 3-layer honeycomb structure, this mailer delivers superior cushioning that protects against bending, compression, and transit damage.

The 20 * 45 + 5 cm size is ideal for items that standard mailers cannot accommodate. The self-adhesive peel-and-seal closure provides a secure, tamper-evident seal, while the honeycomb core replaces plastic bubble wrap entirely. Aligned with PPWR recyclability principles, this mailer is fully recyclable, biodegradable, and plastic-free.

Ideal for art sellers, fabric shops, print shops, and e-commerce sellers who ship long, narrow items.
