Coex poly mailer bags are becoming one of the most popular packaging solutions today. Made from co-extruded polyethylene layers, these bags offer strength, durability, and protection for a wide range of shipping needs. They are lightweight, waterproof, tamper-evident, and easy to customize. Let’s explore five key uses of Coex poly mailer bags in daily business and logistics.
1. E-commerce Shipping
Online stores use Coex poly mailers to ship clothes, accessories, cosmetics, and other non-fragile items. These bags help reduce shipping weight and cost, while still protecting products from dirt, water, and handling damage. They’re a must-have for fashion brands, online marketplaces, and dropshipping businesses.
2. Document Mailing
Need to send invoices, contracts, or reports? Coex mailers are perfect for documents. Their waterproof surface keeps papers dry, while the tamper-proof seal protects sensitive information. They’re a smart and professional choice for offices, legal firms, and banks.

3. Product Packaging
Aside from shipping, many companies use Coex poly mailers as product packaging. The sleek design and smooth surface make them ideal for presenting items in-store or for giveaways. The inside can be black or gray to protect privacy, while the outside is printable for branding.
4. Secure Mailing
Coex poly mailers offer excellent security. The permanent adhesive flap ensures that once sealed, the bag cannot be opened without tearing. This helps prevent tampering and keeps the contents safe, especially during long-distance or international shipping.
5. Custom Branding
One of the biggest advantages is custom printing. Businesses can print logos, slogans, or contact details directly on the mailer. This boosts brand visibility and adds a professional look. It’s packaging and marketing — all in one.
Conclusion
Coex poly mailer bags are a versatile and efficient solution for modern packaging needs. Whether you run an online store, send out documents, or want secure and branded shipping, these bags deliver reliability and style in one smart package.
