Typical Specifications

Typical throughput

For semi-automatic L-sealers with heat tunnels, throughput typically ranges from 10 to 25 packs per minute, depending on product size and operator efficiency.

Power supply

Units of this type commonly require a 3-phase electrical supply, typically 400V, with a power rating that can range from 5 kW to 15 kW for the combined sealer and tunnel.

Film compatibility

This class of equipment is typically compatible with various shrink films, including PVC, POF (polyolefin), and PE (polyethylene), in gauges commonly found for product wrapping.

Maximum product dimensions

The sealing area of an L-sealer like the Belca BLA 60 40 suggests it can accommodate products with widths up to approximately 550-600mm and lengths up to 350-400mm, with a typical height clearance in the tunnel of around 200-250mm.

Footprint

A combined semi-automatic L-sealer and heat tunnel typically requires a floor space of around 2000-3000mm in length and 800-1200mm in width.

Construction material

Frames and external panels are commonly constructed from painted mild steel, with some product contact parts or critical components potentially in stainless steel.

Frequently Asked Questions

• What is an L-sealer and how does it work with a heat tunnel?

  An L-sealer creates two seals (one side and one front/back) around a product using a single L-shaped sealing bar. After sealing, the product passes into a heat tunnel where hot air shrinks the film tightly around it.
