Ulma PV-350

• Packaging of fresh produce such as fruits and vegetables (e.g., aubergines, tomatoes).
• Wrapping of irregular or delicate products that require support from below.
• Forming hermetic seals for products in the meat and dairy sectors.
• General food market applications requiring flexible and reliable packaging.
• Packaging of bakery items or confectionery where product orientation is critical.

Typical throughput

For this class of inverted flow wrapper, speeds commonly range from 40 to 100 packs per minute, depending on product size and film type.

Film placement

Inverted flow wrappers like the Ulma PV-350 position the film reel below the product, which is beneficial for unstable or heavy items.

Power supply

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

Product dimensions

The feeder width and length will dictate the maximum product size. Buyers should confirm specific feeder dimensions for this unit.

Construction materials

Commonly constructed from stainless steel in product contact areas for hygiene, with painted steel for the main frame.

Footprint

The overall footprint for an industrial flow wrapper can vary significantly, typically requiring several square metres of floor space.

• What is an 'inverted flow wrapper' and why would I need one?

  An inverted flow wrapper feeds the packaging film from below the product. This design is ideal for products that are delicate, irregular, or difficult to push, as they are supported by the film throughout the wrapping process.

• Can this machine handle different product sizes?

• What kind of film does this machine use?

• What are the typical maintenance requirements for a used Ulma PV-350?

• Is it possible to integrate this machine into an existing production line?

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.
