Comek/Propema VPB 400 Bag-in-Bag Packing System

• Producing multipacks of snack foods such as crisps, nuts, or confectionery.
• Packaging small, individual items into larger, secondary bags for retail or bulk distribution.
• Automating the collation and bagging of multiple pre-packaged units.
• Suitable for operations requiring high-volume secondary packaging of flexible pouches.

Typical throughput

For this class of equipment, throughput can typically range from 20 to 60 multipacks per minute, depending on product size and film characteristics.

Power supply

Commonly, units of this type require a 3-phase electrical supply, typically 400V, 50Hz, with a power consumption of 5-10 kW.

Air consumption

Pneumatic systems are often integrated, requiring a compressed air supply, typically 6-8 bar, at a flow rate of 200-500 litres per minute.

Film compatibility

Designed to work with various heat-sealable film types, including laminates and co-extruded films, commonly up to 400mm film width for the primary bag.

Bag dimensions

The VPB 400 model typically produces bags with widths up to 200mm and lengths up to 300mm for the individual bags, and larger for the outer multipack.

Footprint

A complete system of this nature, including conveyors and packing tables, typically requires a floor space of approximately 5m x 4m.

• What is a 'Bag-in-Bag' system?

  A 'Bag-in-Bag' system refers to packaging multiple smaller, pre-packaged items (e.g., individual crisp bags) into a larger, secondary bag. This creates a multipack for retail or bulk sale.

• What kind of products can this system handle?

• Is the Markem Imaje printer included and functional?

• What maintenance is typically required for a system like this?

• Can this system be reconfigured for different product counts per multipack?

Form-fill-seal machines hold strong reputations in food packaging for reliability and consistent output. Buyers typically prioritise machines with clear maintenance histories and verified production specifications. Key strengths include versatility across film types and product formats, alongside relatively straightforward operation. When purchasing used units, inspectors should examine seal quality consistency, film tracking accuracy, and the condition of heating elements. Machines from established manufacturers generally command buyer confidence. Downtime for repairs is a common concern, so availability of spare parts and technical support merits careful consideration before acquisition.
