Patented flow-pack seal crimp jaws

Ferret has been the exclusive distributor for over 40 years of the Lako Tool brand, leader in the design of seal and welding tools.

In particular, among the top products of the brand, we cite the patented crimp hot and cold film sealing jaws, that stand out for their modular construction: the jaw, divided into two parts along the midline of the resistance, in fact guarantees the uniform distribution of heat over the entire sealing surface. The use of a thermal compound eliminates all air bubbles and ensures perfect contact between the jaw and the resistance, facilitating the replacement of the latter and the maintenance of the seal insert. To improve the film flow, the sealing surface is subjected to a special treatment, which removes any residue, reducing the friction coefficient. The stainless steel construction ensures excellent thermal conductivity and wear resistance (hardness 34/36 HRC).
Lastly, thanks to its modular design, the sealing insert can be replaced quickly and easily, without dismantling the crimper while maintaining the centering and machine settings. This user friendly interchangeability enables the closure to be suited to the type of wrapping material, optimizing the thermal yield and performance of the flow-packaging machine in terms of speed and waste reduction.
