Advantages of evoh

The advantages of EVOH

EVOH has always been the most widely used high barrier material.The PP/PS/PET film type of this material is in addition to the non-tensile type, there are bidirectional tensile type, aluminum vapor plating type, adhesive coating type, etc., bidirectional tensile type, there are heat-resistant type for aseptic packaging products.The barrier property of EVOH depends on the content of ethylene. Generally speaking, when the content of ethylene increases, the gas barrier decreases, but it is easy to process.

EVOH is characterized by excellent barrier to gas and excellent processability, in addition to excellent transparency, gloss, mechanical strength, elasticity, wear resistance, cold resistance and surface strength.

In the packaging field, EVOH composite film intermediate barrier layer, used in all the hard and soft packaging;In the food industry, aseptic packaging, hot cans and cooking bags, packaging dairy products, meat, canned fruit juices and condiments;In non-food, used for packaging solvents, pesticides, chemicals, air conditioning structural parts, gasoline drum lining, electronic components.

In terms of food packaging, EVOH plastic containers can completely replace glass and metal containers, many domestic aquatic companies export seafood using PE/EVOH/PA/RVOH/PE five layer co-extrusion membrane vacuum packaging.At the same time, EVOH tensile orientation is also being studied abroad. The barrier property of the new EVOH film to gas is 3 times that of the existing high performance non-tensile EVOH film.

In addition, EVOH can also be used as barrier material to be coated on other composite resin packaging materials to enhance the barrier performance.
