Custom Printed Co-Extruded Poly Mailers (commonly known as Courier Bags, Express Mailing Bags, or Self-Sealing Shipping Bags).
Production ConnectionThe Material: The underlying film is typically manufactured on an ABA Co-Extrusion Blown Film Machine [6787566216823361968, -2004461889437687970]. To make standard poly mailers, the "A" layers are white or colored for a clean exterior appearance, while the "B" core layer is black or dark gray to provide 100% opacity, ensuring the contents inside the package remain completely private.The Branding: Custom text, business logos, social media handles, and website URLs are printed onto the rolls using a Flexographic Printing Machine before the conversion stage.The Final Shape: A High-Speed Courier Bag Making Machine folds the film, adds the distinctive pocket seal flap, applies a continuous strip of high-tack hot-melt adhesive with a peel-off release liner, and cleanly cuts the film into finished individual mailers.DetailsClosure System: Features a permanent self-sealing peel-and-stick adhesive strip on the top flap that creates a highly secure, tamper-evident closure.Material Properties: Made from heavy-duty low-density polyethylene (LDPE) or co-extruded plastic blends, making the mailers highly tear-resistant, puncture-proof, and completely waterproof.Utility: Heavily utilized by e-commerce brands, courier services, and fulfillment centers as a lightweight, cost-effective alternative to cardboard shipping boxes for non-fragile items like apparel, footwear, and textiles.If you are planning a production run for these specific types of opaque shipping envelopes, let me know if you want to know about common thickness configurations (like 2.15 mil / 55-60 microns), recycled material options, or dual-adhesive strip designs for customer returns.Production ConnectionThe Material: The underlying film is typically manufactured on an ABA Co-Extrusion Blown Film Machine [6787566216823361968, -2004461889437687970].
