Ulma PV350

• Packaging delicate or irregularly shaped products that benefit from bottom film feeding.
• Suitable for fresh produce, baked goods, meat products, and certain non-food items.
• Often used for products requiring hermetic sealing and a protective atmosphere.
• Ideal for creating pillow-pack style bags with a fin seal on the underside.

Typical throughput

For this class of inverted flow wrapper, speeds commonly range from 40 to 120 packs per minute, depending on product size and film type.

Power supply

Units of this type typically require a 3-phase electrical supply, commonly 400V, 50Hz, with varying amperage requirements based on configuration.

Film compatibility

Inverted flow wrappers are generally compatible with various heat-sealable films, including shrink films, laminated films, and barrier films.

Product dimensions

The maximum product dimensions are determined by the jaw width and former size, which can vary significantly between specific machine configurations.

Machine footprint

A complete system, including an inverted flow wrapper and a shrink tunnel, typically requires a substantial operational area, often exceeding 5-7 metres in length.

Running direction

This unit is specified as Right to Left, which is an important consideration for integration into existing production lines.

• What does 'inverted flow wrapper' mean?

  An inverted flow wrapper feeds the film from below the product, which is beneficial for delicate, unstable, or irregularly shaped items as they are supported by the film throughout the wrapping process.

• What is the significance of the included HRX400 Shrink Tunnel?

• The description states 'needs rebuilding'. What does this imply for a buyer?

• What kind of maintenance is typically required for this equipment?

• Can this machine be used for products other than pork loins?

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.
