Ulma PV350 Inverted Flow Wrapper

• Wrapping delicate or unstable products that require support from below during the wrapping process.
• Packaging products with irregular shapes or those prone to shifting, such as fresh produce or bakery items.
• Creating hermetic seals for products requiring extended shelf life or protection from contaminants.
• Handling sticky or wet products where the film needs to contact the top surface first to prevent build-up on sealing jaws.

Typical capacity

For this class of equipment, throughput can typically range from 60 to 150 packs per minute, depending on product size and film type.

Power supply

Commonly, units of this type operate on a 3-phase electrical supply, typically 400V, 50Hz, with varying power consumption based on configuration.

Film types

Inverted flow wrappers are typically compatible with a range of heat-sealable films, including plain and printed polypropylene, laminates, and shrink films.

Product dimensions

The maximum product dimensions for this class of machine are typically up to 300-350mm in width and 100-120mm in height, with length being more flexible.

Construction material

Units designed for food processing, such as this Ulma PV-350 SPH-C, are typically constructed from stainless steel for hygiene and durability.

Control system

Modern inverted flow wrappers commonly feature PLC control systems with touch-screen interfaces for easy operation and recipe management.

• What is an inverted flow wrapper used for?

  An inverted flow wrapper is designed to package products where the film is fed from below the product, making it ideal for delicate, unstable, or irregularly shaped items that need support during wrapping.

• What are the benefits of stainless steel construction?

• Can this machine handle different product sizes?

• What does 'SPH-C' in the model name signify?

• Is a shrink tunnel necessary with this wrapper?

• What maintenance is typically required for an inverted flow wrapper?

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.
