Poly Mailers – 2.3 Mil Self‑Seal Shipping Bags (10×13 & 12×15.5)

Ship with Confidence. Every Single Time.

Your customers judge your brand the moment their package arrives. KELVO poly mailers make sure that first impression is a good one — arriving intact, dry, and professional-looking no matter what the shipping journey throws at them.

Built to Protect What You Send

• 2.3 mil thick — heavy-duty construction that resists tears, punctures, and rough handling
• Waterproof — keeps contents dry through rain, humidity, and transit exposure
• Strong self-seal adhesive — peel-and-stick closure holds firm so nothing comes loose in transit
• Lightweight — won't add unnecessary weight that drives up your shipping costs

Two Sizes for Every Order

• 10" × 13" — ideal for clothing, accessories, documents, and small soft goods
• 12" × 15.5" — perfect for larger apparel, multi-item orders, and bulkier soft goods

Stock Up and Save

Available in four pack sizes — from the 100-count Starter pack to the 500-count Business Pack — so you can match your order volume and keep your cost-per-mailer low.

Less time fussing with packaging. More time growing your business.
