EVOH Selection Guide—Grades, Processing & Supply

In the food, pharmaceutical and chemical industries, customers are placing increasing emphasis on the oxygen barrier properties of their packaging. EVOH (Ethylene Vinyl Alcohol Copolymer) is one of the most widely used functional materials in this context, not because of ‘high performance’ gimmicks, but because of its direct impact on product shelf life, transport stability and regulatory compliance.

We are a professional raw material supplier of virgin plastics, providing EVOH pellets in many specifications for a long time, and helping packaging enterprises, bottle blank factories and film factories to solve the following problems:

1. How to choose EVOH? Ethylene content is not the higher the better

The biggest difference between different grades of EVOH lies in the ethylene content and melt index. Products with high ethylene content have good flexibility and are suitable for stretching or bottle blowing; low ethylene content has stronger barrier properties and is suitable for use as an intermediate layer in multi-layer films.

If you are:

making food packaging film: recommend models with EVOH content of 27~32 mol%
blow moulding bottles or containers: choose models with a wide processing window and good compatibility
making multilayer structures for injection moulding: need melt indexes adapted to the co-extrusion equipment

We offer a variety of models including E105A, E105B, E171B, L171A, EV4405, F101A and K102, covering the mainstream process routes.

2. Oxygen barrier performance is not the only indicator, processing stability is more critical

Customers often focus on the oxygen transmission rate (OTR) of EVOH, but in actual processing, moisture sensitivity, resin adhesion, and coextruded interlayer compatibility are the key points that affect mass production.

We will provide matching suggestions according to your application process (blown film, injection moulding, casting, extrusion coating) and target material combinations (PP, PE, PET, etc.), to avoid the ‘theoretically feasible, but practically unstable’ misunderstanding of material selection.

3. What can we offer?

Flexible combination of small sample trial + batch delivery

Tie resin can be supplied to help multi-layer co-extrusion solutions

4. Application scenarios at a glance

Blow-moulding bottles: ketchup, soy sauce, flavouring liquid, Lubricants, deodorants

Multilayer films: fresh food packaging, vacuum bags, soft cans, cheese, coffee

Pharmaceutical packaging: inhalers, liquid bottles, sealed bags

Industrial packaging: chemical inner bags, anti-corrosion and oxygen barrier inner layers

5. Quick overview of regular EVOH models: no more blind choices

In order to help our customers understand the available options, we have compiled a list of the EVOH raw materials that are currently available in stock, covering a wide range of different vinyl contents, flexibility and processing styles, They cover a wide range of ethylene content, flexibility and processing methods, and are widely used in the production of food, pharmaceutical, industrial and multilayer structural products.

Click on the model name to see detailed parameters and application recommendations.

For each EVOH material, we provide a complete list of properties, application examples and selection guidance to help you quickly determine the most suitable product solution.

Tips:

Different models in use also involves the compatibility with PE/PA/PP and other materials, if you need specific recommendations, please send your product structure or process conditions to us, we will provide matching suggestions and small sample test support.

6. GET IN TOUCH WITH US

EVOH is not a general-purpose material, it is a functional material that ‘must be used together’. True selection is not just about looking at a list of parameters, but also about understanding the role it plays in your structure.

If you are looking for an EVOH raw material supplier with a stable supply, clear parameters and technical support, please contact us. We will be happy to assist you with prototyping, co-extrusion testing and mass production selection.
