Double-Core Honeycomb Mailer 18.5x(28+4)cm - 4-Layer Ultra-Cushioning for Smartphones & Small Electronics - Biodegradable

This 4-layer honeycomb mailer (18.5 cm wide, 28 cm long + 4 cm flap) offers double-density protection for medium-sized delicate electronics such as smartphones, power banks, portable hard drives, and small cameras. The dual honeycomb core (two separate honeycomb layers) absorbs impacts from multiple directions, reducing the risk of screen damage or internal component shock. The outer kraft layer is tear-resistant, and the inner kraft is smooth to prevent scratches. Self-seal adhesive closure included. Made from 100% recycled kraft paper, fully compostable and recyclable. A plastic-free alternative to bubble wrap and foam.

Company Introduction

Our 18.5x28cm size is particularly popular for shipping iPhones and Android devices. We use water-based adhesives and solvent-free lamination.

Choose HUANCHEER for the greenest, strongest paper mailer on the market.
