Packaging of LIQUID, CREAMY, or VISCOUS forms into self-forming bags – for large and small businesses.
Unipak – Compact machine for dispensing products into a bag with 4 seals (SACHET) that is automatically formed during packaging.
Unipak machine for dispensing liquid products into bags with 4 seals (SACHET)
Unipak is a highly efficient, fully automatic machine constructed from stainless steel, designed for economical packaging of liquid, creamy and viscous products into self-forming bags with four seals (SACHET), with maximum dimensions of 150 x 200 mm. The work process is managed via a Programmable Logic Controller (PLC), encompassing dosing, measuring, bag formation, sealing, batch printing, and counting of the finished product. All machine functions are monitored by sensor subsystems, and in accordance with Industry 4.0 standards, Unipak features an online monitoring system for remote management and adjustment of customer production parameters.
Reliable packaging in self-forming bags for various industries
Flexibility (quick and easy switching to another format)
Stability (high precision and repeatability)
Long service life (20 years on average)
Syrups, shampoos, creams, gel, ketchup, mayonnaise, soy sauce, oils, etc
Pharmacy, Food, Cosmetics, Chemistry, etc.
4.800 bags/hr (40 or 80 cycles/min)

Main modules
Basic machine
It can be simplex or duplex; It consists of a supporting structure, a mechanism for carrying the roll and introducing the foil and a system for forming the bag (mechanism for transverse welding, a tool for vertical cutting and a mechanism for transverse cutting of the bag)
Dispenser for liquid forms
Intended for dosing liquid, pasty and viscous materials; It consists of a dosing cylinder, a suction and pressure valve and a suction basket; it is made as a special piston pump, and the change of the dosage volume is done on the touch panel
Output conveyor
It is intended for the transport of packed bags; It consists of a base, a conveyor belt and an electric drive; It has an adjustable tilt angle; The construction allows for complete mobility; The control is connected and synchronized with the base machine
Other elements of the Unipak machine: Protective Plexiglas cabinet with safe micro switch, Monitoring system for remote monitoring and adjustment…
Modules compatible with the Unipak machine (optional): “eazy open” bag cutting system, CHECKWEIGHER weight check system, Industrial INK JET printer…
