EVOH by Eval™

Oxygen barrier

EVAL™ resin provide excellent barrier properties against the permeation of oxygen. Several factors influence the barrier performance.

Permeating gas

EVAL™ resin have very good barrier properties against the permeation of oxygen, but also of other gases, such as carbon-dioxide, nitrogen, ...

Barrier in multilayer structures

In multilayer structures, it is the properties of the different layers that determines the barrier properties of the overall structure.

Resistance to solvents

When EVAL™ EVOH is used in a multilayer structure, it prevents the evaporation of chemical substances.

Barrier to fuel vapors

The fuel barrier of EVAL™ EVOH is about 4,400 times stronger than that of high-density polyethylene.

Barrier to aroma permeation

EVAL™ EVOH provides an aroma barrier which is used in food, healthcare and agrochemical packaging.

Luster and transparency

The use of EVAL™ EVOH as outer layer allows for a luster look and feel. The packaging can also be left transparent keeping the valuable contents visible.

Flex crack resistance

The EVAL™ barrier layer makes sure that the integrity of the barrier remains unharmed during transport, handling and storage.

Durability

When properly selected, EVAL™ resin will offer a good aging resistance even when exposed to relatively high temperatures.
