Semi-Automatic Strapping Machines
Semi-automatic strapping machines accelerate the strapping process by automating tensioning, sealing, and cutting while the operator positions the strap around the load. This configuration balances throughput with flexibility, accommodating a wide range of load sizes and shapes without requiring full inline conveyor integration.
Tensioning and Sealing
These machines use variable frequency drive tensioning to deliver consistent strap tension across every cycle. The GT41 N vibration weld strapping head creates sealless joints by fusing the strap overlap, eliminating the need for metal seals or buckles. This produces clean, high-strength joints on 1/2" to 5/8" strapping materials.
Throughput and Operation
Cycle rates range from 15 to 40 straps per minute depending on operator speed and load positioning. The easy-access head design simplifies strap clearing and routine maintenance, minimizing downtime between production runs. Semi-automatic configurations can be set up as standalone stations or integrated into combination strap-and-wrap packaging lines.

Automatic Strapping Machines
Fully automatic strapping machines deliver high-throughput, inline pallet and bundle strapping with consistent tension, sealing, and cutting. These systems process up to 8 straps per minute using 1/2" to 5/8" PET strapping with variable frequency drive tensioning and vibration weld sealless joints via the GT41 N strapping head.
Composite Strapping
Composite strapping manufactured from high-tenacity polyester yarns with a polymer coating, available in both cord and woven configurations. Designed as a safe, lightweight alternative to steel strapping for heavy-duty load securing. Widths range from 1/2 to 1-1/2 inch with break strengths from 1,070 to 6,125 lbs. Composite strapping weighs approximately 75% less than steel, produces no sharp edges, does not rust or corrode, and absorbs shock and vibration during transit. Secured with wire buckles or metal seals rather than requiring specialized sealing tools.
Hand Strapping Tools
Hand strapping tools provide versatile and reliable solutions for strapping various packages, ensuring efficiency and ease of use. Suitable for different applications, these tools feature adjustable settings and ergonomic designs for consistent and secure strapping.
Polyester Strapping
Polyester (PET) strapping for medium to heavy-duty load securing applications where high break strength and superior tension retention are required. Available in widths from 1/2 to 1-1/4 inch with thicknesses from 0.020 to 0.050 inch and break strengths from 600 to 5,000 lbs. PET strapping retains applied tension significantly better than polypropylene, making it the preferred choice for loads that settle, compress, or shift during transit. Serves as a lighter, safer, and corrosion-free alternative to steel strapping for many heavy-duty applications.
Polypropylene strapping
Polypropylene (PP) strapping for light to medium-duty load securing, palletizing, and bundling applications. Available in widths from 3/8 to 5/8 inch with thicknesses from 0.015 to 0.031 inch and break strengths from 130 to 600 lbs. PP strapping offers the highest elongation of any strapping material (15-25%), allowing it to absorb shock and impact during transit. Compatible with manual tensioners, battery-powered tools, and automatic strapping machines. Available in both hand-grade and machine-grade coil configurations.
Tabletop Strapper
Tabletop and light-duty strapping machines handle smaller packages, cases, and light bundles with cycle rates up to 20-30 straps per minute. These compact units use 1/2" to 3/4" PET straps with vibration welded joints via the GT41 N strapping head, operating on standard 120V single-phase power.
