Continuous shrink wrapping lines

Side seal shrink wrapping machine

A side seal shrink wrapping machine is considered when production needs continuous sealing rather than a conventional L-seal cycle. It can be useful for longer products, higher output or lines where a continuous longitudinal seal is better suited to the pack format.

Side seal versus L sealer

L sealers are widely used for cartons, boxes and retail packs with a clear L-shaped end seal.
Side sealers can be considered for continuous operation and longer products.
Both routes still need careful film selection and a matched heat tunnel.
The right choice depends on product length, speed and how packs are presented to the infeed.

Output and pack handling

Continuous sealing can support higher throughput, but only if product spacing, infeed timing and tunnel capacity are specified correctly. The bottleneck may be upstream handling rather than the sealer itself.

Specification review

Before choosing side sealing, compare the product size range, film width, packs per minute and required finish against an automatic L sealer route.

Specification summary

For a reliable recommendation, send product dimensions, photographs, required output, film preference, available floor space, power and compressed air details. Lancing UK can then check the correct machine aperture, heat tunnel size, conveyor layout and operator access before quoting.
