Grafted Orevac® Packaging applications
|
Flexible Packaging
PA / Orevac® / PE - EVA - EBA
PE / Orevac® / PA / Orevac® / PE
Orevac® adhesive are designed to reach high adhesion between PA & polyolefins and are optimised for the best performance at the lowest cost.
PE / Orevac® / EVOH / Orevac® / PE
- The usual barrier material for these applications is EVOH, which provides a long shelf life.
- As a results of Arkema's long experience in the yield of grafting technology and adhesion science, specific Orevac® adhesive resins have been developed.
Aluminium / Orevac® / PP
- These structures are currently used for lidding of retortable packaging.
- Specific PP based Orevac grades are available with suitable rheology for extrusion coating.
Rigid Packaging
PE / Orevac® / EVOH / Orevac® / PS
PE / Orevac® / EVOH / Orevac® / PET
PP / Orevac® / EVOH / Orevac® / PP
- Commonly used barrier materials for these applications are EVOH and PET.
- Thermoformability is an important criteria for the processing of the structure.
- Specific Orevac® adhesive resins have been developed to bond PS, PA, PET or EVOH efficiently to polyolefins.
PP / REGRIND / Orevac® / EVOH / Orevac® / PP
HDPE / REGRIND / Orevac® / PA
- The required performance for these structures could be high barrier properties (oxygen, gas, aroma), chemical resistance or specific mechanical properties.
- The Orevac® adhesives resins, specific for such applications, have suitable rheology for the blow moulding process, providing outstanding adhesion to PA or EVOH barrier materials, with good recycling characteristics.
