12.09.2022 As pioneers, SAM North America, LLC and Aquapak Polymers Ltd. (USA & UK) are conjointly developing high performance paper based packaging which is recyclable as well as environmental friendly with multiple end-of-life options.
Aquapak manufactures a range of
thermally-extrudable PVOH polymers whereas SAM designs and produces specialty
extrusion coating and laminating lines.
Key
role for Extrusion Technology Center
SAM’s North American Extrusion Technology
Center plays a key role as on the state-of-the- art extrusion line, the unique
formulations are tested and readily scalable to production. Samples produced
are available for further testing or conversion into product for evaluation.
For instance, the recent work with Aquapak
covered the application of Hydropol –
23g/m² at speeds of up to 250m/min.
As well as the close cooperation with
Aquapak on recyclable paper packaging, SAM is also working with them on
biopolymers such as PLA, PHA etc.
Adaptation
of the extrusion line
Unique features and capabilities of the SAM
line include:
- to stabilise the edges for high speed
coating with low melt strength polymers, an edge encapsulation capability
- for low temperature processing at higher
outputs, a special low shear / low temperature feed screw
- to allow a better chill roll release of
bio-polymers tackified for improved bond to paper, a release coated chill roll
Presently, SAM is also continuing to work
on web pretreatment for improved paper bond which is covering also chemical
priming, corona, ozone, and flame treatment.
The experts of SAM and Aquapak are exhibiting at the K 2022 Show in Düsseldorf, Hall 5, booth A32.
