The history of shrink packaging machines in Japan began with a sheet of nori and a heating wire. "Is there any way to efficiently dry or roast nori using electricity?" That single phrase became the foundation for the innovative "Kyowa-style nori processing machines," which led the nori processing industry towards mass production and industrialization. And it is this "Kyowa-style nori roasting machine" that is the prototype of the current Kyowa Electric-made "shrink tunnel." Kyowa Electric Co., Ltd. continues to advance as a pioneer in shrink packaging towards the next generation. For more details, please contact us or download the catalog.

The Super Shrink Tunnel ROSSO α/β completes the shrink process all at once by directly irradiating the shrink film with a heat source and wavelength. Compared to conventional shrink tunnels, it allows for shorter machine lengths and lower electrical capacity while achieving the same performance, making it space-saving and economical. Since it only shrinks the shrink film, there is minimal thermal impact on the contents, making it effective for packaging low-temperature items, thin plastic containers, glass, and metal that could not be finished neatly with traditional methods. Its compact design does not require a specific installation location, and when used in conjunction with a cover-type tunnel, it enhances effectiveness by applying preliminary shrinkage (models K-800 and K-1000). Additionally, it features easy operation via a touch panel, allowing data input for each item, making it easy to accommodate a variety of products and small lots. The tunnel section is equipped with a lift-up system as standard, facilitating maintenance. The clearance of the heater blocks on both sides can be adjusted with a handle (with position indicator). By adopting a cooling circuit, the furnace is cooled simultaneously with the heater cut-off, automatically stopping operation. For more details, please contact us or download the catalog.
