Introduction to Courier Bags and Express Bags<\/h2>\n<p>Courier bags, also known as express bags or poly mailers, are lightweight, durable, and tamper-evident packaging solutions designed for shipping documents, apparel, e-commerce products, and small parcels. These bags are typically made from polyethylene (PE), polypropylene (PP), or recycled materials, offering waterproof, tear-resistant, and cost-effective protection. The global courier bag market has seen exponential growth driven by the rise of e-commerce, last-mile delivery services, and the need for sustainable packaging. In 2025, the market size exceeded $4.5 billion, with projections to reach $6.8 billion by 2030.<\/p>\n<h2 id=\"toc-3f00518d721ab277df4c3cfd6e1f20db\">2.
