Jowlroel Poly Mailers 10x13 Inch Thank You 100-Pack — Waterproof, Peel-and-Seal, Grey Lined

Jowlroel Thank You Poly Mailer 10x13 Inch (100 pcs) are lightweight, waterproof polyethylene shipping bags with a permanent peel-and-seal closure designed for secure, private parcel delivery.

These 10 x 13 inch poly mailers come in a bulk 100-count set and are built for everyday e-commerce shipping. Manufactured from new polyethylene with a 2.4 mil thickness on one side, they combine low weight with puncture resistance and a grey inner lining to protect customer privacy. The permanent adhesive strip seals quickly and prevents re-opening at the closure, while reinforced edges resist tears and bursting during transit.

How do these mailers protect my products during shipping?

The construction balances light weight with durability to reduce postage costs without sacrificing protection. Reinforced sealed edges and a thicker side minimize tearing, and the waterproof material helps keep contents dry in wet conditions.

• 2.4 mil single-side polyethylene for puncture and tear resistance
• Reinforced edge sealing to prevent bursting
• Waterproof exterior shields packages from rain and moisture
• Grey interior liner for extra opacity and discreet shipments

How easy is it to prepare and seal a package with these polymailers?

Sealing is fast and foolproof: peel away the strip to reveal a permanent adhesive and fold the flap to lock the mailer. Once closed, the adhesive holds permanently, deterring tampering and simplifying packing for high-volume orders.

• Peel-and-seal adhesive for quick one-handed closure
• Permanent glue that prevents re-opening at the closure
• Consistent manufacturing helps easy loading and stacking
• Reduced need for extra tape or packaging materials

What items suit the 10x13 inch size and how should I size products?

The 10 x 13 inch dimension is ideal for soft goods and compact items such as apparel, small accessories, prints, and textiles. Use the sizing guidance to choose the correct mailer: add product length plus height plus a 2-inch allowance for length, and product width plus height plus a 1-inch allowance for width.

• Good for T-shirts, socks, small books, and cosmetics
• Apply length = product length + product height + 2 inches
• Apply width = product width + product height + 1 inch
• Helps avoid crushed or bulky shipments

Are these mailers suitable for businesses that need privacy and branding?

Yes — the grey interior lining reduces transparency to protect customer privacy, while the outer surface can accept ink or printed thank-you messages depending on your printing method. They’re a practical choice for small businesses that ship frequently and want a tidy, branded unboxing experience.

• Grey-lined interior prevents visible contents
• Outer surface works with many label types and printed stickers
• 100-pack quantity supports regular order fulfillment
• Lightweight design lowers shipping fees compared with boxed shipments
