Обзор смолы сополимера этилена и винилового спирта (EVOH) E171A

Ethylene-Vinyl Alcohol Copolymer EVOH E171A

EVOH E171A is an ethylene-vinyl alcohol copolymer (EVOH) resin developed by Kuraray Co., Ltd., designed for applications requiring extremely high gas barrier performance, and is ideal for multilayer food packaging, medical containers, and industrial barrier films.

Kuraray EVAL™ EVOH E171A Advantages

Excellent oxygen barrier properties - Extending the shelf life of food and medicine

EVOH E171A can effectively block oxygen and carbon dioxide, extend the shelf life of food and medicine, maintain their freshness, help companies reduce waste and improve product quality.

Related product recommendations:

If you need higher antioxidant performance, EVOH E105A may be a suitable choice, which is particularly outstanding in gas barrier performance and is particularly suitable for food stored for a long time.

Similarly, our PPS (polyphenylene sulfide) pellets also provide excellent heat resistance, suitable for packaging applications in high temperature environments.

Excellent mechanical properties - ensure stable and durable packaging

EVOH E171A has a tensile strength of up to 35 MPa and a flexural modulus of 4800 MPa, which ensures the structural integrity of multi-layer packaging and ensures that the product is not easily damaged during transportation and storage.

Recommended matching materials:

If stronger compression resistance is required, PP (polypropylene) granules are also a good choice for more complex packaging designs and high-load applications.

Stable processing performance - improve production efficiency

The material has a melt index of 1.7 cm³/10min (190°C), providing smooth extrusion, coextrusion and blow molding performance.

Further optimization:

If you have high transparency requirements during processing, PET (polyethylene terephthalate) can be used together with EVOH materials to provide better transparency and chemical resistance.

Kuraray EVAL™ EVOH E171A Приложения

Food packaging

Vacuum bags: used for packaging fresh food, meat, and seafood, greatly extending the shelf life of the product.

Sterilization bags: suitable for heat-treated foods, which can effectively block oxygen and prevent food oxidation.

Thermoformed trays: widely used in packaging of fruits, vegetables, cooked food, etc. to prevent contamination and deterioration.

Related application expansion:

We also provide a series of high-transparency packaging materials, such as APET (UV-resistant PET), which is suitable for transparently packaged products, such as fresh fruits and vegetables, to ensure that the packaging shows the high quality of the products.

Medical and pharmaceutical packaging

Aseptic medicine bottles: The excellent gas barrier properties of EVOH E171A ensure that the drugs are protected from oxidation and effectively extend the shelf life of the drugs.

Inhalers: Packaging used to precisely control the release of drugs to ensure the stability and safety of drugs.

Industry expansion:

If you are looking for stronger chemical resistance and solvent resistance, our POM (polyoxymethylene) series of materials can provide excellent solutions for the packaging of medical devices and precision equipment.

Industrial packaging film

Automotive fuel system film: used for fuel tank and fuel pipeline films, providing extremely high barrier properties to ensure that fuel does not leak.

Agricultural film: In agricultural product packaging, it effectively prevents oxygen penetration and extends the storage period of agricultural products.
