COFFEE BAGS & AROMA PROTECTION PACKAGES
Coffee
beans keep the delicious aroma of coffee inside of it. After roasting process
coffee beans slowly begin to lose their aroma and flavor. For that reason
coffee beans must be protected by high barrier package against external factors
such as oxygen and UV light. The most known barrier type of the coffee bags is
aluminum which is providing perfect oxygen and UV barrier.
Anatomy of Coffee Bags
Coffee bags
are generally consisting of 3 layers. Outer layer usually made from easy
printable materials such as PET or OPP. Middle layer is always acts as a
barrier and made from aluminum or MET/PET. Inner layer made from PE which is suitable
for food contact.
Why Coffee Bags Have Valves?
When you buy roasted coffee bean from any coffee shop or super market the
valve on the bag will attract your attention.
Coffee bag valve is a simple air valve which is works one way direction.
After roasting process coffee start to release carbon dioxide and that gas must
be exhausted from coffee bags with valve.
On the
other hand these air valves should never allow the air entry the coffee bag.
Because coffee beans do not like oxygen. Coffee bag valves made from PE which
is suitable for PE inner layer of coffee bags.
As we Pal
Plastik only use coffee bag valves which is suitable for food contact and have
food contact relevance certificates.
100% Recyclable Coffee Bags
Standard
coffee bags are not suitable for recycling because of aluminum barrier. For
that reason Pal Plastik developed alternative barrier for coffee bags. To
provide high oxygen barrier and aroma protection we use special multilayer EVOH
barrier on our coffee bags. EVOH layer with its multilayer structure provide
perfect oxygen barrier. On the other hand these coffee bags are suitable for recycling.
