Dow – Symbiex lamination technology obtains food approval for barrier applications
SWITZERLAND • Symbiex solventless fast curing adhesive introduced to the market at drupa 2016 together with Nordmeccanica’s Duplex SL One Shot lamination line, has been granted global food approval for use in the production of barrier laminates in Europe, the USA and China.
As a further development of this new product, web speed improvements from 25% up to 50% combined with high surface quality can be achieved when used on metallized PET/PET, Aluminium/PET and OPA/PE-EVOH substrates.
Because there are no pot life concerns and first-class curing performance being evident, customers report significant cost savings opportunities thanks to:
- Equipment simplification: No need for a mixer and heating room.
- Increased efficiency: Less line downtime due to reduced cleaning frequency and an additional opportunity for further productivity gains.
- Material savings: Reductions in scrap because bond quality checking is possible 30 minutes after lamination.
Besides productivity and cost improvements, the technology remains first in class when it comes to providing laminators with versatility and flexibility to their operations. With food compliance reached as early as 24 hours after lamination – as compared to traditionally three to four days –, Symbiex is a key enabler to help meet customer needs for fast and most effective supply of packaging.
Compared to a traditional lamination line, the Duplex SL One Shot laminator from Nordmeccanica features a unique system to handle the solventless lamination, enabling the two adhesive components to come into contact as late as possible in the process. With two independent high-precision coating stations, the two films are pressed together only in the lamination nip station where the curing of the Symbiex adhesive takes place. This method eliminates the need of a mixing unit and hence pot life concerns, and offers reduced line downtime and easy cleaning.
A Duplex OneShot lamination line is available for demonstrations at Nordmeccanica’s headquarters in Piacenza, Italy. Customers interested to sign up for an individual appointment, may contact the local Nordmeccanica or Dow sales representatives.
