The 12 x 15 1/2 inch Flat Ship-Lite® Envelope is a white mailer built from paper bonded with a poly-mesh screen of interlocking fibers, producing a material six times stronger than conventional paper envelopes. The integrated mesh construction also delivers inherent moisture resistance, reducing the risk of content damage during transit without adding meaningful weight to the package.
The self-seal adhesive strip allows fast closure without tape or additional equipment, making these envelopes well suited to high-volume pack-out in e-commerce fulfillment centers, print distribution operations, retail replenishment programs, and B2B correspondence workflows. The interior footprint comfortably accommodates flat documents, folded printed materials, soft goods, and lightweight products.
The white exterior presents a clean, professional appearance compatible with standard label applicators and thermal transfer printers. Each case contains 100 envelopes and ships via parcel carrier.
