From the brand

POLYSELLS began with a passion for secure shipping and a commitment to protecting the contents of every package. Our founders, driven by the frustration of damaged shipments and lost items, embarked on a mission to create shipping envelopes that offer unparalleled protection. Inspired by the resilience of polyethylene material, they dedicated themselves to developing innovative, tear-resistant postal mailing bags that redefine shipping security.

Deliver with Confidence, Arrive with Security

HOODIE-READY SIZE & BUNDLE CAPACITY: Stop worrying about fit. At 14.5″ x 19″, these mailers are specifically sized for high-volume clothing sellers. Comfortably fit thick winter hoodies, denim jeans, or Poshmark bundles that smaller 12×15″ bags can’t handle. The generous width allows you to seal the flap without forcing the seams, ensuring a professional look for every order.
TAMPER-PROOF “SET & FORGET” ADHESIVE: Engineered for high-stress transit. Our ultra-strong, wide adhesive strip creates a permanent seal that won’t “pop” under pressure from bulky items or melt in hot delivery trucks. Once sealed, it is tamper-evident—it will tear the bag before opening—giving you and your customers peace of mind that the contents are secure without needing extra packing tape.
HEAVY-DUTY TEAR & PUNCTURE RESISTANCE: Built to survive the warehouse floor. These waterproof mailers feature reinforced side seams and high-density polyethylene that resists punctures from shoe box corners, book edges, and zippers. They offer the professional “heft” of brands like Fuxury, ensuring your apparel arrives clean, dry, and rip-free even in rain or rough handling.
100% OPAQUE FOR TOTAL PRIVACY: Protect your brand and your customer’s privacy. The multi-layer white exterior is completely opaque—zero transparency even when shipping black leggings or bright neon apparel. The clean, crisp white surface provides a professional “boutique” feel and is optimized for thermal labels and permanent markers, ensuring barcodes scan perfectly every time.
THE SMALL BUSINESS “SWEET SPOT” VALUE: This 100-pack offers the perfect test quantity for occasional sellers and growing small businesses who need “bulk-grade” quality without the storage headache. Designed to be lightweight to keep you in lower USPS Ground Advantage tiers, these mailers save you money on both material costs and postage compared to bulky boxes.
