Retail cartons
Presentation shrink wrapping for boxed products where the final pack needs to look clean and controlled.
L-sealer applications for cartons, bundles and retail packs
Plan the seal, film and finish around the packs you need to wrap.
Use cases
L-sealer machine applications
L-sealer projects are best planned around the product entering the seal area and the finished pack leaving the heat tunnel.
Printed materials
Books, brochures and printed packs where the film protects and presents the item for storage or dispatch.
Grouped packs
Multi-packs and bundles where shrink film creates a stable grouped unit before secondary packing.
Contract packing
Flexible projects with changing products where changeover planning and pack data need to be checked early.
Consumer goods
Cosmetics, hardware, household items and electronics where the finished pack must be neat and repeatable.
End-of-line support
Integration with conveying, coding, labelling, carton packing or dispatch handling where shrink wrapping is one stage in the line.
Film and finish
Plan the seal and shrink finish together
The correct L-sealer route depends on the film, product stability, heat tunnel settings and line speed. A pack may seal well but shrink poorly if tunnel temperature, airflow and conveyor speed are not balanced with the film and product.
- Confirm pack dimensions and weight.
- Confirm film material and thickness.
- Review heat sensitivity of the product.
- Check pack presentation standards.
Integration
Where the L-sealer sits in a packaging line
An L-sealer may operate as a standalone packaging cell or as part of a wider line. Infeed, spacing, film loading, shrink tunnel outfeed and finished-pack handling all need to be practical for operators and maintenance.
