The Design Concept: Sophisticated Utility for the Modern Brand
Our Gusseted Kraft Envelope is designed for those who value both aesthetic elegance and functional capacity. Moving beyond standard flat mailers, this design incorporates a 3D expansion architecture that allows for the secure transport of bulky documents, premium catalogues, or textile samples. The natural fiber texture of the kraft paper provides a tactile, organic feel that communicates brand authenticity and high-end craftsmanship.
Engineering Excellence & Material Integrity
Each envelope is constructed from high-density 350GSM long-fiber kraft paper, providing a superior burst strength and a sturdy, rigid structure that resists creasing. The precision-engineered 40mm gusset is creased with a 0.1mm tolerance, ensuring the envelope maintains its sharp, professional profile even when filled to capacity. The integrated circular Velcro closure is tested for over 1,000 opening cycles, offering a reusable and secure fastening solution that eliminates the need for single-use adhesives.
Sustainable Elegance & Global Standards
At Starmi, we believe premium packaging should be a circular experience. The reusable Velcro design extends the product life cycle, significantly reducing environmental impact. Made from FSC-certified materials and fully compliant with EUDR standards, this envelope is the perfect eco-conscious choice for the European and North American luxury markets.
