- Components fully integrated in the line control system
- Smile Control System – an intuitive, simple-to-use human-machine interface
Line Types
The benchmark for flexibility in production.
The SML FlexPack®
FlexPack® is a well-proven SML concept which raises the bar for flexibility and simplicity in coating and lamination. It has been specifically engineered for the dynamic packaging market, but found its place also for technical applications. All options are on the table for customers thanks to the line’s compact and modular design.
The system guarantees a thoroughly safe, cost-effective and user-friendly production while delivering extraordinary product quality. Its modular design means that the coating and laminating line can be custom-engineered for your specific needs, even making it possible to create highly complex lines with relative ease based on our modular construction system.

New horizons for breathable products.
DoubleCoat
Coating layer thickness reduced to an absolute minimum, very high water columns and sensational values for breathability: It even allows materials combinations which where considered to be incompatible so far.
DoubleCoat is SML’s new patented, sequential coating process for the manufacture of breathable products - i.e. in the field of sanitary articles, for the construction industry or for disposable clothing.
Combine the options and gain the edge.
The SML Triplex lines for aseptic packaging
Packaging for beverages extracted from natural food sources such as fruit juice present a particular challenge in the engineering of systems and processes. SML’s coating and laminating lines can be used to manufacture complex composite carton packaging in one simple and cost-effective process.
The centrally controlled 'Smile Control System' plays a key role in this, allowing you to manage the activities simply and conveniently.
| Products | Aseptic board packaging |
|---|---|
| Product width | 700 - 1,650 mm |
| Lamination weight | 15 - 25 g/sqm |
| Inside weight | 20 - 40 g/sqm |
| Decor weight | 12 - 25 g/sqm |
| Total product weight | 150 - 400 g/sqm |
| Maximal operating speed | 400 m/min |
Your advantages:
- Production of aseptic board laminates of high quality
- Optimised product change over - low waste
- Durable machine design and comfortable operation
Ready for heavy loads.
SML’s fully automatic drum winder, W1800, is fitted with an automatic reel and shaft handling system and supports the winding of heavy product rolls of up to 4 tons.
