Heat shrink packaging equipment
Heat shrink packaging machine
A heat shrink packaging machine is the combination of sealing and controlled heat required to wrap a product in shrink film. Depending on the product, that may mean a chamber sealer, L sealer with heat tunnel, sleeve sealer or a more integrated shrink wrapping line.
Main machine types
- Chamber sealing machines for compact all-in-one shrink wrapping.
- Semi automatic L sealers for batch work and medium throughput.
- Automatic L sealers with heat tunnels for repeat production.
- Sleeve sealers for grouped trays, bottles and multipacks.
Why heat control is important
The heat stage determines the final appearance and pack integrity. Poor tunnel control can cause loose film, burnt film, dog ears, cloudy finish or distorted products.
How to shortlist equipment
Start with pack dimensions, film type, finish requirement and target output. Then check line length, utilities and operator access before deciding on automation level.
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.
FAQ
Heat shrink packaging machine FAQs
What is a heat shrink packaging machine?
It is machinery that seals shrink film around a product and applies heat so the film tightens around the pack.
What is the difference between an L sealer and a heat tunnel?
The L sealer forms and seals the film; the heat tunnel shrinks it to create the finished pack.
Which film is used for heat shrink packaging?
POF and PE films are common choices, but selection depends on product, pack strength and presentation requirements.
