Orevac™ Adhesive Resins Flexible Packaging
| Medium oxygen barrier structures |
Construction |
|
Multilayer structures used for the packaging of meat, fish and cheese with a standard shelf life.
Commonly used barrier materials for this type of packaging are polyamides. |
PA, OREVAC, PE, EVA, EBA |
 |
Specific grades of Grafted Orevac™ Resins are designed to reach high adhesion between polyamides and polyolefins.
Grafted Orevac™ Resins are optimized for the best performance at the lowest cost. |
PE, OREVAC PA, OREVAC PE |
|
| High oxygen barrier structures |
Construction |
|
| EVOH based multi layer structures are generally used for lamination, lids and vacuum packaging.The oxygen barrier material for these applications is EVOH, providing a longer shelf life. |
PP, OREVAC, EVOH, OREVAC PP |
 |
| PE, OREVAC EVOH, OREVAC PE |
|
| Aluminum Based Structures |
Construction |
|
PP based Grafted Orevac™ Resins are used in these lid structures for re-sealable packaging.
Adhesive Orevac™ Resins are available with suitable rheology for extrusion coatings. |
Aluminium OREVAC PP |
 |
| Grafted Orevac™ Resins are used in the production of multi-layer structures that combine the performance of a polyolefin (mechanical resistance, sealing or water barrier properties) with that of an oxygen barrier material such as polyamides or EVOH copolymers such as Soarnol® copolymer. |
 |
| Grafted Orevac™ Resins are anhydride grafted polyolefins based on PE, EVA, EMA or PP. Anhydride provides the polarity and reactivity which give high adhesion levels on various substrates such as: Polyamides, EVOH, PET or Aluminium. By the right selection in the Grafted Orevac™ Resins range, the polyolefin based backbone induces outstanding compatibility and adhesion with the polyolefins used in the outer layers of the multilayer structure. |
 |
| All Grafted Orevac™ Resins are suitable for use on coextrusion equipment designed for polyolefin processing. The rheology of each grade is well-suited to the implementation of multi-layer techniques: blown or cast film coextrusion, sheet coextrusion, blow molding coextrusion, coextrusion coating, etc. |
|
| Sheet barrier structures |
Construction |
|
| Orevac™ Resin multilayer structures are suitable for thermoformed packaging for meat, fresh salad and snacks.Commonly used barrier materials for these applications are EVOH and PET. |
PS, OREVAC, EVOH, OREVAC PE |
 |
| Grafted Orevac™ Resins bond PS, PET or EVOH efficiently to polyolefins, and are suitable for thermoforming. |
PP, OREVAC, EVOH, OREVAC PP |
|
| Blow Mold Coextrusion |
Construction |
|
Blow mold coextrusion allows bottles with an Orevac™ Resin multi layer structure to be produced for soups, fruit juices and sauces.Orevac™ Resin based multilayer structures provide good barrier properties to oxygen.
Grafted Orevac™ Resins provide outstanding adhesion to PA or EVOH barrier materials and are available with suitable rheology for blow molding processing. |
