Making the best use of the materials loop with PET.

Closing the material loop up to 100 % recycling will be increasingly important in the future. PET is particularly suitable for this task as one of the few raw materials that is available world-wide at a defined quality as recycled material.

We are at the leading edge in technology and quality as far as our roll stacks are concerned.


This is clear to see from SML’s specially developed SPG (smart parallel gap) rolls, which makes it possible to achieve perfect thickness tolerances every time.


An evolution for the hot drinks market.

Foamed PET sheet

PET has not been considered suitable for cups and mugs filled with hot food and drinks, as it deforms and becomes unstable at high heat. Until now, that is. At SML, we are constantly pushing the boundaries of what is possible. And we can prove it with our PET sheet extrusion lines for the production of foamed A-PET sheet.


The result is a brand-new and innovative production method for sheeting undergoing a thermoforming process to create trays and cups for high-temperature applications in an efficient and cost-effective way. Exactly what is in demand in this price-sensitive market.
