Inline Pocket Application System for Transparent Invoice/POD Pouches

The Pocket Attaching Equipment is a fully automatic add-on module designed to produce and attach transparent pockets (invoice pouches / POD sleeves) onto courier bags during the production process. This system operates inlinewith existing courier bag making machines, enabling seamless integration for manufacturers who need to add pocket functionality to their current lines.
If the existing courier bag machine does not have a pocket-making function, this unit upgrades it instantly—allowing the user to manufacture courier bags with adhesive or welded transparent pockets in various sizes.

Key Functional Features

✔ Full Inline Operation
Works inline with any courier bag cutting and sealing machine, synchronizing perfectly with production speed and workflow.

✔ Automatic Pocket Production
The system forms the transparent pocket (invoice pouch) from a separate film roll and prepares it for attachment onto the moving courier bag web.

✔ Compatible with Different Pocket Sizes
Designed to attach pockets of various dimensions depending on the courier bag specifications.

✔ Advanced Heat-Air Welding Technology
Equipped with a dual-lane hot air sealing system (double hot air sealing heads) that securely and cleanly welds the transparent pocket onto the courier bag without distortion.
