Comtex 4G

Inbound and Outbound Polypackers

BVM Brunner GmbH: Seitenschweissmaschine Comtex 4G


Comtex 4G – the machine for fully automatic packaging of alternating inbound items in coloured film for shipping or returns processing.

A three-sided, sealed package is produced in combination with transparent or coloured semi-tubular film. Working in-line and controlled via light curtains, this machine can alternately process inbound products of different sizes within its size range. The products do not have to be pre-sorted.

The machine is set to the maximum possible sizes. Depending on the product width, this creates a film overhang that is sealed off in a downstream side sealing station. A tight film bag is produced around the product on all sides by scanning the size during the packaging process and tightly sealing the film overhang in both directions.

An item packaged in opaque film and ready for dispatch with a shipping label is fed to the shipping department. This concept is also based on the requirement of packaging textile returns in mail order houses and has been extended to the shipping packaging through the use of coloured film. The processing of other products such as books of various sizes (Book On Demand) and magazines with inserts (gimmicks) is also possible.

The Comtex 4G can be used for both inbound and outbound products. Compared to the Comtex 3G, the Comtext 4G covers a wider and higher product range (sealing width 750 mm, belt width 600 mm) that is usually in demand for outbound applications.

The new generation of fully-automatic mail order and returns packaging line is available with or without labelling. In the Comtex family, the operation of the side sealing station has been fundamentally changed to increase performance. This makes outputs of up to 1800 parts per hour possible. A patent application has been filed for this innovation.
