Overview of Ethylene Vinyl Alcohol

Ethylene Vinyl Alcohol (EVOH) is a high-performance copolymer known for its exceptional gas barrier properties, chemical resistance, and clarity. It is produced by hydrolyzing ethylene vinyl acetate copolymer, resulting in a material that offers outstanding resistance to oxygen and aroma transmission. Due to these characteristics, EVOH is widely used in advanced packaging and multilayer polymer structures.

In industrial specifications, it is commonly referred to as ethylene vinyl alcohol copolymer, EVOH polymer, or ethylene vinyl alcohol polymer. Properties such as ethylene vinyl alcohol melting point and ethylene vinyl alcohol solubility are critical factors in determining processing conditions and end-use suitability.

Application of Ethylene Vinyl Alcohol

Barrier Layer in Packaging & Multilayer Films

Ethylene Vinyl Alcohol is extensively used as a barrier layer in multilayer packaging films and containers due to its excellent oxygen and aroma barrier performance. It helps extend shelf life by preventing oxygen ingress, making it ideal for food, pharmaceutical, and sensitive industrial packaging applications.

In multilayer structures, EVOH is often used in combination with materials such as Ethylene Vinyl Acetate to improve flexibility and processability. These applications are closely aligned with requirements in polymers, where high barrier performance and material compatibility are essential.

Plastic Containers, Bottles & Flexible Packaging

Ethylene Vinyl Alcohol plays a significant role in the manufacture of plastic containers, bottles, and flexible packaging materials. Its transparency and barrier efficiency allow it to be incorporated into coextruded structures without compromising appearance or mechanical integrity.

In packaging systems, EVOH may be layered with Polyethylene to achieve the desired balance between barrier protection, strength, and cost efficiency. These applications support industries requiring reliable protection against gas permeation and product degradation.

Automotive, Industrial & Speciality Polymer Applications

Ethylene Vinyl Alcohol is also used in automotive fuel systems, industrial hoses, and speciality polymer components where resistance to fuel permeation and chemical exposure is required. EVOH-based layers help reduce emissions and improve system durability.

In these applications, it may be combined with Polyamide Resin to enhance mechanical strength and thermal stability. These uses are preferred in industries demanding high-performance materials capable of withstanding harsh operating conditions.
