Kempner - 2024 Kempner Packing and Labelling Line

• Packaging of bakery items such as donuts, pastries, and cakes.
• Wrapping and sealing of small to medium-sized retail products.
• Bundling multiple items for promotional or multi-pack sales.
• Protecting products from dust, moisture, and tampering during transit and storage.
• Applying promotional or informational labels to packaged goods.

Typical throughput

For this class of automatic L-sealing and shrink-wrapping lines, throughput can typically range from 20 to 60 packs per minute, depending on product size and film type.

Power supply requirements

Units of this type commonly require a combination of single-phase (220-240V, 50Hz) for control systems and three-phase (380-415V, 50Hz) for the heat tunnel, with total power consumption varying but often in the range of 15-25 kW for the complete line.

Maximum product dimensions (L-sealer)

The sealing bar dimensions on L-sealers of this size commonly accommodate products up to approximately 500mm in length and 350mm in width.

Film compatibility

This type of equipment is typically compatible with various shrink films, including PVC, POF (polyolefin), and PE, in thicknesses commonly ranging from 12 to 30 microns.

Label applicator speed

Automatic label applicators on such lines are typically capable of applying labels at speeds matching the packaging line's throughput, often up to 60 labels per minute.

Footprint

A complete automatic L-sealing, shrink tunnel, and labelling line commonly requires a linear footprint of approximately 4 to 6 metres in length and 1.5 to 2 metres in width, plus space for access.

• What types of products can this line package?

  This type of line is suitable for packaging a wide range of solid or semi-solid products that can be L-sealed and shrink-wrapped, commonly including food items, cosmetics, stationery, and small industrial components.

• Is specialist film required for shrink wrapping?

• What level of operator intervention is typically needed?

• Can the label applicator handle different label sizes?

• What are the common maintenance requirements for such a system?

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.
