Metal Seals for Strapping/Banding
16x25mm Semi Open Serrated Metal Seals for Strapping/Banding
These 16x25mm semi open serrated metal seals are designed to create a secure, consistent joint when tensioning and sealing strapping/banding around loads. Used with the appropriate strapping sealer, the serrated inner profile bites into the strap as the seal is crimped, helping the strap hold tension during handling, storage and transit. They are a popular choice for general industrial bundling and pallet unitising where a dependable mechanical seal is required.
Key Features
Semi open design: The semi open profile helps guide the strap into position and supports fast, repeatable sealing in busy packing environments.
Serrated grip: Serrations are intended to improve holding power by increasing friction and mechanical bite when the seal is crimped with a compatible tool.
Made for strapping/banding: Suitable for use as a joining seal on strapping systems where a metal seal is specified.
Consistent sealing: When paired with the correct sealer and correct strap type/width, seals help deliver a uniform closure across multiple packs.
Compact 16x25mm format: A practical seal size for many common strapping applications without adding unnecessary bulk at the joint.

16x25mm Semi Open Serrated Metal Seals — Full Product Guide
Choosing the right seal is as important as choosing the right strap. The seal is the joint that transfers tension from one side of the strap to the other, so it must match the strap width and be compatible with the sealing method. This guide explains what semi open serrated metal seals are, how they are typically used, and what to consider when selecting them for your packing operation.
How It Works
In a typical strapping process, the strap is placed around the load and tensioned to the required tightness. The seal is then positioned over the overlapping strap ends and crimped using a compatible sealer. During crimping, the seal deforms and the serrations engage with the strap surface. This creates a mechanical interlock that helps the strap maintain tension and resist slip.
Because the seal is a formed metal component, correct tool selection and correct technique matter. A properly applied seal should be evenly crimped and aligned, with the strap seated correctly inside the seal before sealing.
Materials and Construction
These are metal seals intended for strapping/banding. The serrated internal profile is designed to increase grip once crimped. The semi open style is commonly chosen for efficient loading of the strap into the seal during packing, helping operators work quickly while maintaining consistent placement.
Strap Compatibility (Width, Type and Tooling)
Metal seals must match the strap width they are designed for. This product is specified as 16x25mm, and is typically used where a 16mm strap width is required. Always confirm compatibility with your strap type and your sealing tool before use.
- Width match: Use a seal that matches the strap width to ensure the strap sits correctly and the crimp forms as intended.
- Tool match: Use a sealer designed for the seal style (semi open) and strap width.
- Application method: Follow your tool manufacturer’s guidance for correct crimp pattern and number of crimps.
Floor Type Compatibility
As a consumable component, the seal itself is not floor-dependent. However, your overall strapping workflow may be influenced by your packing area. In high-throughput environments, consider how seals are stored and presented to operators (e.g., at a packing bench, on a mobile strapping station, or at a pallet wrapping area) to reduce handling time and improve consistency.
Health and Safety
Strapping systems can store significant tension. For safe use:
- Use the correct tensioner and sealer for your strap and seal type.
- Wear appropriate PPE such as gloves and eye protection when tensioning and cutting strap.
- Keep hands clear of the seal and tool jaws during crimping.
- Dispose of used seals and strap offcuts safely to avoid sharp-edge hazards.
Ideal Applications and Use Cases
These semi open serrated metal seals are commonly selected for industrial packing tasks where a metal seal closure is preferred. Typical scenarios include:
- Pallet unitising: Keeping multiple cartons or mixed items stable on a pallet during transport.
- Bundling: Holding long or irregular products together for easier handling.
- Warehouse dispatch: Creating a secure strap joint for outbound shipments.
- Manufacturing: End-of-line packing where repeatability and speed are important.
Maintenance, Cleaning and Care
Metal seals are typically single-use consumables and do not require maintenance. For best results, focus on maintaining your strapping tools:
- Keep sealer jaws clean and free from debris that could affect crimp quality.
- Inspect tools regularly for wear that could reduce sealing performance.
- Store seals in a dry area to keep them clean and ready for use.
Case Study (Example Workflow)
A typical warehouse dispatch team may strap palletised cartons before collection. After placing edge protection where needed, the operator loops the strap around the pallet, tensions it to stabilise the load, slides a semi open serrated seal over the overlapping strap ends, and crimps the seal using a compatible sealer. The result is a compact, secure joint that helps the pallet remain stable through handling and transport.
Who is it for?
- Warehouses and distribution centres strapping pallets for outbound delivery
- Manufacturers bundling products for storage or shipment
- Packaging teams that require a metal seal closure for their strapping system
- Operations looking for a straightforward, repeatable sealing method
Colours / Features Available
These are metal seals; colour options are typically not applicable. The defining feature is the semi open format with serrated internal grip.
Sizes Available
This listing covers the 16x25mm seal size. If you use other strap widths or seal styles, you may require a different seal size and/or a different sealing tool. If you are unsure which seal is correct for your strapping, share your strap width and tool type and we can help you select a compatible option.
Note: Always test seals with your specific strap and tool combination to confirm performance for your load, handling conditions and transport requirements.
