Our heavy-duty PE courier bags have multiple core advantages compared to ordinary express bags. First, the HDPE material provides a tensile strength of more than 25MPa, which is 3 times higher than ordinary PE bags, making it resistant to tearing and puncturing during handling and transportation. The waterproof design prevents items from getting wet during rainy weather or long-distance shipping, protecting documents, electronics, and clothing from water damage. The self-adhesive tamper-evident strip not only provides a fast seal but also has a tear-off design that allows customers to easily verify whether the package has been opened, improving delivery security. Additionally, the bags are compatible with most courier sorting equipment, and custom printing supports up to 6 colors, meeting the brand promotion needs of e-commerce sellers.
