Bosch launches flow wrapper at Pack Expo

The Pack 301 Inverted 'Long Dwell' Flow Wrapper is the latest addition to Bosch’s Pack series of horizontal form fill seal (HFFS) machines.

It is capable of gentle product handling and hermetically sealed seams and features a consistent seal time independent of the machine’s product flow, said Bosch. This guarantees an air-tight seal even during ramp up and down periods for extended product shelf life and less waste.

The Pack 301 ID is suited to packaging fresh produce, soft products, multi-packs, meat and dairy and pharmaceuticals as well as other products that are difficult to handle using a traditional upright flow wrapper or require modified atmosphere packaging.

Control of processing temperature​

'Long dwell' sealing times of up to one second ensure hermetically sealed packages. A feature that allows independent control of the processing temperature on both the top and bottom sealing jaws accommodates thicker films, further ensuring seal quality

The machine’s inverted flow-wrapping technology gently transports the food directly on to the film from the product former through the cutting head, greatly reducing jams and ensuring a superior package appearance.

The Pack 301 ID features a modular film backstand that can be located in various positions relative to the infeed and wrapper, allowing users to optimize the film path. The result is reduced film waste.

Additionally, the equipment has the flexibility to adapt to specific applications, such as products that are loose in the infeed flight and require stronger seals. It can also be used with both automated and manual systems to meet manufacturers’ diverse needs.

Simplified maintenance​

With its design based on total productive maintenance (TPM), the Pack 301 ID assures simplified maintenance and maximum uptime. The machine has also been reduced to a minimum number of parts to make it highly operator-friendly.

Additionally, the Pack 301 ID features an open access design for quick cleaning and reduced downtime. Operators can change and clean knives without tools, as well as simply exchanging the transport belt at the cutting head for quick cleaning.

Easy jaw alignment further simplifies format changes and crimper cleaning. In addition, hinged guide rails allow easy access for loading the product and clearing any jams.

“Manufacturers are always searching for packaging solutions that offer superior performance while ensuring product safety,”​ said Craig Collett, product line director, Bosch Packaging Technology. “For products that are difficult to handle, the Pack 301 ID is a solution that solves both of these challenges.”​
