Creating solutions together.

Our engineers and technicians relentlessly strive to craft the best solution for our customers. No matter the task or challenge you have in store for us, we will work together with you at the Redlham pilot plant to develop ideal solutions that go above and beyond the latest industry standards.

On 2,800sqm one demonstration line from each of our product groups is available for demonstrations and test runs. SML supports you to realise your ideas and test them sufficiently.


Line Types

Available demonstration line types:

Mono-material film and multi-layer structures

Cast film line with advanced MDO technology


With SML's multi-purpose cast film line access is given to a future-oriented technology to develop new packaging solutions with focus on mono-materiality, enhanced processability and easier recyclability of the produced film.

The integrated MDO unit enables the development of products with superior properties - especially in terms of printability, transparency and with regards to tear properties.

SML sheet products

Besides trials on standard products, the design of the line enables the production of specialities such as:


  • rigid PET sheet up to thicknesses of 2mm with excellent optical properties
  • physically foamed sheet of PET, PP and PS
  • laminates of PET/PE sheet

High-tech and versatile

FlexPack® coating and laminating line


SML's flexible extrusion coating and laminating line is dedicated to test specific raw materials, to further develop processes, to improve the properties of end products and to work on new, more eco-friendly applications.

Based on a variety of different technical features, SML’s FlexPack® pilot line can be used for a vast array of applications: from flexible packaging to breathable hygienic textiles and from industrial composites to construction industry applications.
