SK Functional Polymer Introduces OREVAC® 18603, A Performing Extrudable Tie Layer for PET Based Oxygen Barrier Multilayer Packaging
In the packaging field, OREVAC® 18603 is currently used as tie resin in co-polyester based lidding film. Such kind of lidding solution is directly sealable onto mono material CPET or APET based container which opens through a so-called burst peel mechanism. Thanks to its adhesive performances, OREVAC® 18603 is the appropriate tie resin solution in order to develop shrinkable film and produce lidding film exhibiting drum effect (film with low shrink ratio). It is also the right solution to manufacture polyester shrinkable film on triple or double bubble blown to pack chunk of meat or cheese (film with high shrink ratio).
OREVAC® 18603 shows outstanding thermal stability. Therefore, it can be extruded several time and be easy recycled. Thanks to its high compatibility with both polyester and polyethylene, it can be used as compatibiliser in PE/PET blend in mechanical recycling process. OREVAC® 18603 also fosters APET or CPET recycling and contributes to the circular economy. When combined to co-polyester in a multilayer film, OREVAC® 18603 allows developing lidding solution, which is directly seal-able onto mono CPET or mono APET container (jar, tray or cup). Those mono-material based containers are fully recyclable.
