800 Type High-Speed Automatic Broken Glue Express Bag Machine

Product Introduction

This 800 Type High-Speed Automatic Broken Glue Express Bag Machine falls into the specialized courier and mailer bag converting category. Film is unwound under automatic tension and edge control, tracked by photoelectric systems, formed with reinforced seams, fitted with a rupture flap, sprayed with adhesive, and cut to the required length. Multi-motor dual servo drive keeps the process stable across the published speed range. 

For B2B buyers in the flexible packaging and logistics supply sector, the 800 Type High-Speed Automatic Broken Glue Express Bag Machine offers a practical single-line solution with solid automation. It uses components such as dual servo drive, automatic glue spraying, photoelectric tracking, and imported conveyor elements. Factories can run it to produce standard courier bags that meet everyday shipping demands without extensive secondary processing.

Specific Applications
The 800 Type High-Speed Automatic Broken Glue Express Bag Machine is intended for express and courier packaging production. Detailed applications include:

1. Manufacturing of self-adhesive express bags used by logistics and courier companies for parcel and document delivery.
2. Production of breakable-glue courier bags for e-commerce packaging, online retail shipments, and mailer applications.
3. Conversion of film into reinforced express bags featuring rupture flaps and horizontal reinforcement for stronger seams.
4. Supply of standard-width courier bags suitable for small to medium parcels, lightweight goods, and document mailing.
5. Creation of private-label or white-label express bags for logistics brands and packaging distributors.
6. Production of bags that can later receive printed tracking information, barcodes, or company logos when paired with upstream printing equipment.
7. Support for packaging plants that need reliable output of self-sealing mailer bags for garment, sock, stationery, or general merchandise shipping.

These applications focus on high-volume, standardized self-adhesive courier bags rather than general shopping bags or specialized medical packaging.
