Product Description

Key Features

  • Expandable Wide-Bottom Design: The intelligent gusseted structure allows the bag to stand upright, providing significantly more internal volume for 3D/bulky items compared to flat envelopes.

  • Single or Double-Layer Construction: Choose between lightweight single-layer Kraft or heavy-duty double-layer construction for added thickness and durability while maintaining the natural soft feel of high-quality paper.

  • Smart Dual-Adhesive & Easy-Tear Strip: Two-Way Shipping: Features two adhesive strips—one for the seller to ship and the second for the customer to facilitate a hassle-free return.

    • User-Friendly Opening: Includes a central easy-tear strip for a clean, convenient unboxing experience without the need for scissors.

  • 100% Biodegradable & Sustainable: Made from premium natural Kraft paper, these mailers are fully compostable and recyclable, helping your brand achieve zero-waste goals.
