Poly Mailers:

Poly mailers are a popular choice for all ecommerce businesses. Equipped with an adhesive strip for sealing. Packaging is both simple and fast, providing a great way to ship your goods. Not only are they quick and efficient, they are also water resistant and tamper evident, allowing you to ship your items confidently. They are extremely cheap, lightweight, and take up less space than boxes. They're perfect for non-fragile items.

2.5 Mil Poly Mailer:

These 2.5 Mil poly mailers are the perfect solution for shipping. Stronger than our 2 Mil mailers, these work great when shipping heavier and/or sharper items. With water and tamper resistance, and a self-sealing lip with a synthetic rubber adhesive, these provide a safe and secure way to ship your packages. These mailers are also lightweight which will result in savings during the shipping. Ink, stamps and labels adhere and can be easily seen on the white/grey exterior. Whether shipping clothing, books, or pretty much anything that can fit in the (size) bag, you can ship confidently using these mailers!
