What is EVOH Material<\/span>
\n<\/span><\/span><\/h2>\n

 <\/p>\n

EVOH EV 3851F is a high-performance EVOH material produced by SK Global Chemical Co., LTD. It is designed for extrusion molding and is suitable for a variety of uses such as multi-layer co-extrusion film, shrink film, and thermoforming sheet.<\/span> This material belongs to a heat-stable grade, combining processing flexibility with stable barrier properties, and is particularly suitable for packaging solutions with high requirements for gas barrier properties.<\/span><\/span><\/p>\n

 <\/p>\n

EVOH Material <\/span>EV 3851F<\/span><\/span><\/span>\u00a0Advantages<\/span><\/h2>\n

 <\/p>\n

1. Outstanding oxygen barrier ability<\/span><\/strong><\/p>\n

This material performs well in oxygen barrier properties. According to ISO 14663 test data, at a temperature of 20\u00b0C and a relative humidity of 85%, its oxygen permeability per unit thickness is only 2 cm\u00b3\u00b720\u03bcm\/m\u00b2\u00b724hr\u00b7atm. This value is at a relatively low level among similar EVOH materials, indicating that it can effectively isolate oxygen intrusion and is very suitable for packaging oxygen-sensitive food and pharmaceutical products.<\/span><\/span><\/p>\n

2. Combination of strength and durability<\/span><\/span><\/strong><\/p>\n

In terms of mechanical properties, EV 3851F shows good rigidity and toughness, with a tensile modulus of 4,000 MPa and a flexural modulus of 3,690 MPa. This high-strength performance helps to improve the overall compression and bending resistance of the packaging material, and reduces warping and structural loss during moulding, logistics or end-use processes.<\/span> Even under conditions of high humidity or temperature differences, the material maintains the stable shape and sealing performance of the packaging.<\/span><\/span><\/p>\n

3. Process suitability and processing advantages<\/span><\/span><\/strong><\/p>\n

EVOH EV 3851F has a melt index of 1.8 g\/10min (2.16kg at 190\u00b0C) versus 3.9 g\/10min (2.16kg at 210\u00b0C), which provides good melt flow for a wide range of extrusion processes.<\/span> It can be co-processed with commonly used substrates such as PE, PA and PP to build high-performance multilayer structures, providing more flexibility in production.<\/span><\/span><\/p>\n

4. Excellent thermal stability<\/span><\/span><\/strong><\/p>\n

With a melting point of 173\u00b0C and a Vicat softening point of 162\u00b0C, the evoh material possesses strong heat resistance and is able to cope with challenges in high-temperature moulding and heat sealing scenarios.<\/span> In thermoforming or high-temperature transport environments, it is less prone to thermal deformation, which helps to improve product yields.<\/span><\/span><\/p>\n

 <\/p>\n

EVOH <\/span>EV 3851F<\/span><\/span><\/span>\u00a0Applications<\/span><\/h2>\n

 <\/p>\n

1. Frozen food packaging:<\/strong> Especially suitable for meat, dairy products and other products that need to be kept fresh for a long time, and can maintain a low oxygen permeability even in high humidity environments.<\/span><\/p>\n

2. Pharmaceutical packaging:<\/strong> applied to the packaging of injections, small-volume vials and other products, which can effectively isolate water vapour and oxygen, and protect the stability of active ingredients.<\/span><\/span><\/p>\n

3. Electronic device protection:<\/strong> It is widely used in vacuum packaging or moisture-proof encapsulation of sensitive components to extend storage life and reduce scrap rate.<\/span><\/span><\/span><\/p>\n

 <\/p>\n

[ Practical Application Feedback ]<\/span><\/strong><\/p>\n

A domestic cold chain distribution company chose EV 3851F for its high-end pre-prepared vegetable packaging, and the shelf life of the product was extended by nearly 30%, and the repurchase rate of the users was significantly increased.<\/span><\/p>\n

A multinational pharmaceutical company used EV 3851F in the packaging of its new injections, and the efficacy of the product remained stable during transport in the Southeast Asian market.<\/span><\/span><\/p>\n

A sensor manufacturer reported that component failure rates due to humidity were reduced by nearly half after use.<\/span><\/span><\/span><\/span><\/p>\n
