Packaging of POWDER forms in bags – for large and small business

Unipak – Compact machine for dosing powder products, into a bag with 4 seals (SACHET) that is automatically formed during packaging

Unipak – dosing and packaging in 4-pack bags

Unipak is a highly efficient, fully automatic machine constructed from stainless steel, designed for economical packaging of powdered 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.

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)

Dosing system – Screw dispenser

The drive of the auger is a servo motor, while the hopper has an independent electric drive; Automation allows adjustment of the rotation speed of the screw and the braking force; The size of the dose is determined by the screw angle

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, Screw conveyor for auto-replenishment of the suction basket, 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…
