Streamline your shipping process and ensure your bulky apparel orders arrive in perfect condition with these heavy-duty gusseted poly mailers designed for maximum expansion and ultimate protection.

Managing an e-commerce business requires reliable packaging that can handle the diverse shapes and sizes of modern apparel, and these 15 x 20 x 4 inch white expansion poly mailers are engineered to meet those rigorous demands. The integrated bottom gusset provides a four-inch expansion, allowing you to easily pack thicker items such as sweaters, jackets, or multi-item clothing bundles that standard flat mailers simply cannot accommodate. Crafted from high-quality 2.4 mil thick plastic, these shipping bags offer a superior barrier against punctures and tears while remaining lightweight to help you save on postage costs. The waterproof exterior ensures that your contents remain dry and clean regardless of the weather conditions during transit. Designed for efficiency, the peel and seal closure creates a secure, tamper-evident bond that eliminates the need for messy tape or additional adhesives. Whether you are shipping handmade garments, retail inventory, or soft goods, these professional-grade envelopes provide a clean, opaque presentation that protects customer privacy and enhances your brand's reliability. By choosing these durable expansion bags, you reduce the risk of shipping damage and ensure a positive unboxing experience for every customer. - Expandable Bottom Gusset: The 4-inch expansion allows for the effortless shipping of bulky items like hoodies and blankets without overstretching the material.
