What is a Industrial Strapping Sealer? Types, Uses & Benefits Explained
In today’s fast-paced manufacturing and logistics industry, safe and secure packaging is not an option—it is a necessity. Whether you are shipping cartons, bundling newspapers, securing steel rods, or preparing pallets for export, proper strapping ensures your goods stay intact during transit. One of the most important tools in this process is the Strapping Sealer.
At Eagle Manufacturing Company (established in 1969), we have been delivering reliable packaging machinery solutions for decades. As a leading manufacturer of strapping machines and carton sealing machines, we understand the importance of strong and durable strapping solutions for manufacturing, warehousing, and shipping industries.
In this detailed guide, we will explain everything you need to know about a Strapping Sealer, including its types, uses, working process, and key benefits.
What is a Strapping Sealer?
A Industrial Strapping Sealer is a packaging tool used to secure and lock the ends of a plastic or steel strap around a product, carton, or pallet. It is an essential component in manual and semi-automatic strapping operations.
After the strap is tightened around a package using a tensioner or strapping machine, the strapping sealer clamps and seals the strap ends together using a metal seal or friction-based mechanism. This ensures the strap remains tight and does not loosen during transportation.
Simply put, a Strapping Sealer locks the strap in place to keep goods safe and secure.
Why is a Industrial Strapping Sealer Important in Packaging?
When goods are transported, they go through handling, stacking, vibration, and movement.
Without proper strapping and sealing, packages may:
Shift or collapse
Get damaged during transit
Open unexpectedly
Cause product loss or safety hazards
A high-quality Strapping Sealer ensures:
Strong strap locking
Long-lasting seal strength
Protection against load shifting
Reduced product damage
How Does a Industrial Strapping Sealer Work?
The working of a Industrial Strapping Sealer is simple yet effective:
The strap is wrapped around the package.
A tensioning tool tightens the strap.
A metal seal (clip) is placed over the overlapping strap ends.
The sealer compresses the seal tightly.
The strap becomes securely locked in place.
Some modern sealers use a friction-weld method instead of metal clips, especially in machine-based systems. However, manual sealers typically use metal seals.
Types of Strapping Sealers
Choosing the right Strapping Sealer depends on the strap material, application, and load type. Below are the most common types:

Frequently Asked Questions (FAQs) About Strapping Sealer
A Strapping Sealer is used to lock and secure the ends of a plastic or steel strap around a carton, pallet, or bundled product. It ensures the strap remains tight during storage, handling, and transportation, preventing goods from shifting or getting damaged.
Yes. A tensioner tightens the strap, but it does not lock it permanently. A Strapping Sealer is required to crimp the metal seal or weld the strap ends together to maintain tension and ensure load security.
A Strapping Sealer can be used with:
Polypropylene (PP) straps – for light to medium loads
Polyester (PET) straps – for medium to heavy loads
Steel straps – for heavy industrial applications
The type of sealer should match the strap material for proper sealing strength.
A Strapping Sealer is a tool that seals strap ends after tensioning, usually in manual or semi-manual operations.
A strapping machine automates the entire strapping process, including tensioning, sealing, and cutting.
Sealers are more affordable and suitable for small to medium businesses, while machines are ideal for high-volume production.
When selecting a Strapping Sealer, consider:
Strap material (PP, PET, or steel)
Strap width and thickness
Load weight
Frequency of use
Budget
For heavy-duty industrial applications, pneumatic or battery-operated models are recommended.
Yes. For heavy loads such as steel rods, machinery parts, or construction materials, a steel Strapping Sealer is recommended. These are designed to provide high seal strength and durability.
