Heavy-Duty Kraft Gusseted Mailer with Peel & Seal

The Design Concept: Industrial Strength Meets Eco-Minimalism

In the high-velocity world of e-commerce, your packaging must be a fortress. Our bespoke kraft gusseted mailer is engineered for brands that refuse to choose between rugged protection and environmental integrity. By utilizing a high-capacity expandable structure, we provide a versatile solution that replaces bulky corrugated boxes, reducing storage space by up to 60% while maintaining a professional, minimalist aesthetic.

Artistic Details & Engineering Excellence

This mailer is constructed from premium 250GSM reinforced long-fiber kraft paper, ensuring superior burst strength and tear resistance. The 60mm side gussets allow the envelope to expand effortlessly to accommodate bulky items like apparel, catalogs, or boxed electronics. The extra-wide 40mm permanent adhesive strip features a "tamper-evident" seal, providing an audible and tactile security that protects contents during global transit. Every seam is reinforced with high-precision thermal bonding, capable of withstanding internal pressure of over 12kg without rupturing.

Sustainable Luxury & Global Integrity

At Starmi, we believe durability is the foundation of sustainability. This mailer is 100% plastic-free, crafted from FSC-certified recycled materials, and is fully curbside recyclable. It is treated with EUDR-compliant processes, ensuring your logistics chain meets the most stringent environmental mandates in Europe and North America.
