Poly Mailers 19x24 in 1000-Pack - Bulk White Self-Seal Mailers

Our review of these poly mailers finds them best suited for small businesses and high-volume shippers who need a durable, low-cost outer package. The biggest reason to buy is the combination of scale and convenience: a 1000-pack of 19x24 in white polyethylene mailers with a self-seal adhesive that keeps lightweight non-fragile items protected from moisture and casual tampering. The reviewer found them especially useful for apparel, documents, and similar items where weight savings and opacity matter more than rigid protection.

Key Features

• Size & Quantity: Each pack contains 1000 mailers at 19x24 in internal size, providing a long-lasting supply for frequent shippers and reducing reordering frequency.
• Self-Seal Closure: The built-in adhesive strip secures packages quickly without tape, speeding up packing and ensuring a consistent seal every time.
• Waterproof Material: Made of white polyethylene, the mailers resist moisture during transit, helping to protect clothing and paper goods from light rain or splashes.
• Opaque Privacy Lining: The black inner lining keeps contents hidden for customer privacy and a professional appearance when shipping garments or documents.
• Lightweight & Tear-Resistant: The poly construction is durable enough to resist tearing under normal handling while keeping dimensional weight and postage costs lower than boxed shipments.
• Economical Bulk Packaging: Buying in bulk lowers per-unit cost, making these mailers a cost-effective choice for small to middle businesses.

Who It's For

These mailers are ideal for e-commerce sellers, clothing resellers, and companies that ship large quantities of lightweight, non-fragile goods through common carriers. They work well where reducing shipping weight and packing time is a priority and where items like t-shirts, small soft goods, and documents need simple moisture protection and privacy.

Those who sell fragile or high-value breakables should look to padded or boxed solutions for additional cushioning and impact protection. Also, if a buyer needs clear, reusable, or highly branded packaging, these plain white poly mailers may not meet those specialized needs.
