The thickened courier bag is a heavy-duty shipping bag made from thickened LDPE or HDPE, with a thickness of 0.10mm–0.20mm — far exceeding standard bags (0.05mm–0.08mm). It is ideal for shipping medium-to-heavy items such as apparel, electronics, hardware, books, and more, offering superior tensile, puncture, and impact resistance for long-distance transport and rough handling.
Made from high-quality PE or GRS-certified recycled material, the bag is tough and durable. It features a high-strength tamper-evident adhesive strip for secure sealing. The smooth surface supports custom logo printing and easy label application.
Compared to ordinary courier bags, it offers 30%–100% greater thickness with significantly improved strength and tear resistance. Perfect for high-volume shipping of shoeboxes, small appliances, toolkits, and book sets.
