Designed for high-output production and large orders, these horizontal premade pouch packaging machines handle filling volumes of up to 1500 ml and can work with pouch-in-pouch formats, where a separate inner pouch is accurately placed inside the main outer pouch to create a double-layer package. They have an structure that is useful for special applications, such as packing two reactive components separately in the chemical industry so they only mix at the point of use. An intelligent control system manages the filling of the inner and outer pouches independently, which allows different products and filling sequences to be set and controlled with good accuracy and stable operation.
