Auto Strapping

Why Unistrap HS 1T Auto?

The Unistrap HS 1T is a fully automatic horizontal strapping system suitable for a vast range of strapping applications. 


The Unistrap HS 1T is a robust build strapping machine made of high quality components delivering reliability in the long term, which minimises maintenance costs. The use of the latest technologies provide total control over the strapping over the product and the packaging overall holding force.

The machine is complete with all the necessary devices to perform a fully automatic working cycle. 

The strapping head Unistrap with vibration welding is the evolution of the traditional system with electrical resistance; this system is the result of our technical research and twenty years of experience in the construction of automatic machines for the packaging of palletised units. 

The maintenance of the strapping head with vibration welding is almost non-existent, since it's built with mechanical parts of high precision hardened steel and without delicate components such as temperature detectors, resistors, etc.
