• Sealing pre-filled trays or punnets of fresh produce such as fruit and vegetables.
• Packaging ready meals, prepared foods, and convenience items in a sealed tray format.
• Sealing various dairy products, including soft cheeses or yoghurts in individual portions.
• Used in bakeries for sealing pastries, cakes, or other baked goods in protective packaging.
• Suitable for packaging meat, poultry, and fish products to extend shelf life and ensure hygiene.

Typical throughput

For this class of inline sealer, throughput can typically range from 60 to over 120 packs per minute, depending on tray size and film type.

Power supply

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

Air supply

Pneumatic systems are commonly used for various functions, requiring a clean, dry compressed air supply, typically 6-8 bar.

Film compatibility

Inline sealers are typically compatible with a range of heat-sealable films, including PET, PP, and aluminium laminates, suitable for various barrier requirements.

Footprint

An inline sealing machine, particularly with integrated printing, typically requires a significant linear footprint within a production line.

Tooling changeover

Units of this type are commonly designed for relatively quick tooling changeovers to accommodate different tray sizes, often assisted by dedicated trolleys.

• What types of packaging can this machine handle?

  This type of inline sealer is designed to seal pre-formed trays or punnets, typically made from plastic (e.g., APET, CPET, PP) or pulp, with a heat-sealable film lid.

• Is it suitable for modified atmosphere packaging (MAP)?

• How easy is it to change between different tray sizes?

• What maintenance is typically required for an inline sealer?

• Can this machine integrate with existing production lines?

Used sealing machines are generally valued for their durability and long operational life. Buyers typically prioritize machines with clear maintenance histories and minimal wear on sealing components. Key considerations include film compatibility, seal quality consistency, and ease of adjustment. Reputable models tend to retain functionality well across multiple applications. Industry sentiment suggests these machines offer strong value when sourced from reliable vendors, though operators should verify calibration settings and test seal integrity before full production use.
