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.

SML supports you to realise your ideas and test them sufficiently.

The production of customer samples, the common development of new products and joint test series plays a key role in SML’s partnership with its customers. Joint R&D activities facilitate the mutual understanding, and through it, the anticipative fulfilment of customer wishes. Not least, the findings generated together are having a direct impact on the further development of new machinery and technology at SML.

Keeping you on top form.

Multi-purpose ClassicPET sheet line

With its recent industrial-scale pilot line, SML provides its customers a multi-functional sheet line for intensive R&D activities to further drive circular economy. Customers can use SML's ClassicPET sheet line to test their own specific material and to produce samples of C-PET light, foamed PET and rPET sheet.

A wide variety of recyclable products
The multi-purpose ClassicPET line is able to produce sheets from up to 100 % post-consumer recycled material (PCR) in a general thickness range of 150 - 1,200 µm. A gas injection unit for the core layer extruder is employed to manufacture foamed sheet with material savings up to 60 % for common thermoformed products. And finally, C-PET light sheet combines transparency, recyclability as well as the suitability for the economic production of thermoformed hot-filling products.

Advantages of ClassicPET:

  • New design with 25 % lower footprint 
  • Robust, technically mature and easy-to-operate
  • Minimised loss of intrinsic viscosity
  • Simple product adaptions
  • EFSA, FDA ready

Teaming up for innovations.

Advanced FlexPack extrusion coating and laminating line

From 3rd quarter 2023 onwards, a completely new production scale FlexPack extrusion coating and lamminating line is ready for performance tests, sample production and joint R&D projects.

The state-of the-art FlexPlack line features a number of technical innovations: 
The plant is equipped with three extruders, that are configured to process a huge variety of different polymers - ranging from polyolefins to TPU, TPE, PET PLA and EVOH. The co-extrusion feeblock provides up to five layers, which enables the production of barrier-coated film for flexible packaging now. An additional single unwind is integrated for the production of reinforced laminates.
