BJ-N650H natural gummed kraft paper tape is a water-activated carton sealing tape designed for corrugated boxes used in packaging, storage, and transportation. Made with 65 g/m² kraft paper and a starch-based water-activated adhesive, it forms a secure paper-to-carton bond after moistening and helps provide visible evidence if a package has been opened or tampered with. With a total weight of 85 ± 2 g/m², 0.11 mm thickness, and defined machine- and transverse-direction tensile performance, BJ-N650H provides a specification-driven paper sealing solution for warehouses, logistics operations, e-commerce fulfillment, and general shipping cartons.

Dry on the Roll. Secure After Water Activation.
BJ-N650H natural gummed kraft paper tape uses a starch-based adhesive that remains inactive until water is applied.
Once activated, the tape is applied to corrugated cartons for secure sealing during storage, handling and transportation.
How the Gummed Adhesive Works
Dry Adhesive
The starch adhesive remains dry on the roll for controlled storage and handling before use.
Carton Bond
Water activates the starch adhesive so the tape can bond securely to corrugated carton surfaces.
Key Features:
- 65 g/m² Natural Kraft Paper Backing
Uses a defined kraft paper construction for consistent water-activated carton sealing applications. - Starch-Based Water-Activated Adhesive
The dry adhesive is activated with water before application, creating a secure bond to corrugated carton surfaces. - 85 ± 2 g/m² Total Weight
Controlled paper and adhesive coating weight provides a consistent product structure for packaging applications. - 0.11 mm Total Thickness
A defined tape thickness supports stable handling and application during carton sealing. - MD & TD Tensile Performance
BJ-N650H provides 110 N/25mm tensile strength in the machine direction and 67 N/25mm in the transverse direction. - Tamper-Evident Carton Sealing
The tape bonds to corrugated boxes and helps make unauthorized opening or package tampering more visible during transit.
Primary Uses:
- Corrugated Carton Sealing
Designed for securely closing corrugated shipping and storage boxes. - Shipping & Transit Packaging
Helps keep carton contents protected while packages move through transportation and handling. - Warehouse Packing
Suitable for routine carton sealing at packing stations and warehouse operations. - E-Commerce Fulfillment
Provides a paper-based sealing option for shipping boxes prepared for customer delivery. - Tamper-Evident Packaging
The bonded paper seal helps provide visible evidence when a carton has been opened or disturbed.
