High repeatability
Well suited to repeat products with consistent dimensions.
Flow wrappers
Horizontal wrapping routes for individual packs and regular product formats.
Product option
Flow Wrappers
Flow wrappers are different from L-sealers but can be the correct packaging route for products that need continuous horizontal wrapping. They are often considered for food products, bakery items, bars, stationery, hardware, household goods and similar regular shapes.
- Continuous horizontal wrapping for defined product formats.
- Useful for individual products and repeat pack sizes.
- Can include coding, feeding and downstream packing options.
- Specification depends heavily on product shape, infeed and film type.
Specification guidance
Key checks before quoting
Final machine selection should be matched to real products, film, output, space and available utilities.
| Best fit | Bars, bakery, stationery, hardware and regular product shapes |
|---|---|
| Process | Product infeed, film forming, longitudinal seal and end seal |
| Line needs | Consistent infeed spacing, film control and product stability |
| Quote data | Product size, weight, speed, film type and infeed method |
Why it matters
How this route is usually selected
End-to-end line thinking
Feeding, coding and outfeed handling should be specified as part of the wrapper project.
Alternative to shrink
Often better than L-sealing when the product and output suit horizontal flow wrapping.

When flow wrapping is a better route than L-sealing
Flow wrapping and L-sealing are different packaging routes. L-sealing is often selected for cartons, boxes and shrink presentation packs. Flow wrapping is more commonly considered where a horizontal wrapper forms a pack around individual products such as bars, bakery items or similar products that need a different seal format.
This L-sealer website should not duplicate a specialist flow wrapping domain. The useful role here is to help buyers identify when their product is not a natural L-sealer application and should be discussed as a flow wrapping project instead.
| Selection point | What to confirm | Why it matters |
|---|---|---|
| Cartons and boxed goods | Usually review L sealing and heat tunnel options. | The product shape suits film bag formation and shrink presentation. |
| Bars and horizontal products | Review flow wrapping if a pillow-pack style route is needed. | The pack format is different from an L-sealed shrink bag. |
| Grouped shrink packs | Review sleeve sealing or shrink bundling. | Grouping requirements may not suit L sealing or flow wrapping. |
| Unclear route | Send product samples and finish requirements. | The correct technology should be selected before pricing. |
Information to prepare before a quotation
- Product shape and orientation.
- Required seal style and pack appearance.
- Need for shrink finish or pillow-pack style wrap.
- Output target and infeed method.
- Downstream boxing or collation requirement.

Buyer FAQs
Can a flow wrapper replace an L sealer?
Only when the desired pack format suits horizontal flow wrapping; many carton shrink applications are better reviewed as L-sealing projects.
Should both routes be quoted?
If the pack style is undecided, send samples and finish requirements so the correct technology can be selected first.
Why keep flow content brief here?
This domain is focused on L-sealer machinery; specialist flow wrapping intent should sit with the relevant Lancing route.
What evidence decides the route?
Product shape, orientation, seal style, film requirement and presentation target are key.
Can Lancing discuss both technologies?
Yes. Lancing can help route the enquiry to the correct machinery type.
