Sealless Strap Joints: Our Hand Tool Solutions
August 22, 2025
What is Sealless Strapping?
A method of joining the ends of a steel strap without using a separate metal seal. Instead, a special tool mechanically interlocks cuts in overlapping sections of the strap to attach them to one another, creating a strong and secure connection.
The Benefits of Sealless Strapping of Metal Strap:
• No additional metal seals required, creates a faster and cleaner process
• High tensile strength joints for secure and reliable strapping
• Compact tools that are easy to handle and operate
This sealing method is ideal for heavy-duty packaging, export packaging, and industrial manufacturing—especially in environments where seal loss or contamination may pose a risk to operators.
At Signode, we offer a range of solutions to support sealless joint strapping, including both manual and battery-powered tools.
BST Battery Powered Hand Tool
The BST is a battery-powered hand tool designed for use with strap sizes of 13, 16, and 19 mm, and strap thicknesses ranging from 0.38 to 0.63 mm. It is ideal for high-volume industrial packaging, offering full mobility across the site.
Key features include:
- A touchscreen interface for intuitive operation
- High-speed performance with up to 500 cycles per battery charge
- Seamless and continuous operation for demanding environments
SCL Manual Hand Tool
The SCL is a lightweight, portable manual tool compatible with 13, 16, and 19 mm strap sizes and 0.38 to 0.63 mm thicknesses. It provides a reliable solution for sealless sealing of metal strap in lower-volume or mobile applications.
Best Practices for Sealless Steel Strapping
To create optimal performance:
- Always match the strap width and thickness to the tool’s specifications
- For high-tension applications, use a tool with adjustable tension settings, such as the BST
- The strap should be flat, and aligned before tensioning to allow for effective interlocking
