EVOH has been the most widely used high barrier material. In addition to the non-stretch type, the film type of this material is also biaxially oriented, aluminum-vapor-deposited, and adhesive-coated, and the biaxially oriented heat-resistant type is also used for aseptic packaging products. The barrier properties of EVOH depend on the ethylene content. Generally speaking, when the ethylene content increases, gas barrier properties decrease, but processing is easier.
EVOH is distinguished by excellent gas barrier properties and excellent processability. In addition, EVOH is excellent in transparency, gloss, mechanical strength, stretchability, abrasion resistance, cold resistance and surface strength.
In the field of packaging, EVOH makes a composite film intermediate barrier for use in all rigid and flexible packaging; in the food industry for aseptic packaging, hot and retort pouches, dairy products for packaging, meat, canned fruit juices and Condiments; In non-food, for packaging solvents, pesticides and chemicals, air conditioning structural parts, gasoline barrels lining, electronic components.
In food packaging, EVOH plastic containers can completely replace glass and metal containers, many domestic seafood exporters use PE / EVOH / PA / RVOH / PE five-layer co-extruded film vacuum packaging. While accelerating EVOH composite membrane research, foreign countries are also studying the orientation of EVOH, the new EVOH membrane gas barrier properties of the existing high-performance non-stretched EVOH film 3 times.
In addition EVOH can also be used as a barrier material coated on other synthetic resin packaging materials, to enhance the barrier performance results.
The advantages of EVOH Brief summary:
1. Provide high barrier performance in low humidity environment
2. The chemical barrier effect, including most of the grease, acids and solvent pesticides.
3. High transparency: to ensure the easy operation of the operation
Smell fragrant, feel good
5.EVOH with a variety of polymers to achieve co-extruded production
