Other features include a Siemens PLC control with a touch screen monitor and data storage, and a consistent temperature heating and sealing system that is suitable for all shrink films. The sealer is easily adjustable for all sizes of products. It is driven by a servo sealing head, which ensures accurate positioning and sturdy seals. A double bar device is used to provide machine stability for extra wide products, and the entire structure is fully automatic with a speed controlled in-feed system. This delivers a product speed up to 60 ppm. The high velocity recirculation hot air shrink tunnel offers precise, stable temperature control and can accommodate a variety of films and products.
