EVOH Sinopec

EVOH (Ethylene Vinyl Alcohol Copolymer) is considered to be a more environmentally friendly material, mainly in terms of its advantages in reducing food waste, prolonging product freshness, and in the recycling process.EVOH's gas barrier properties are excellent, and it can effectively prevent oxygen, water vapor, and other substances from entering into the package, thus prolonging the shelf-life of the food, and reducing food spoilage and waste. This feature makes EVOH particularly important in food packaging, and can significantly reduce the environmental burden caused by food expiration or spoilage.     In addition, EVOH has good recyclability, and although its recyclability is not as good as that of materials such as PE (polyethylene) and PP (polypropylene), it can be used in combination with these materials to take advantage of the strengths of both materials; PE and PP have better mechanical strength and chemical resistance, while EVOH provides a better barrier to gases. Through composite use, this multi-layer packaging material ensures packaging functionality while allowing for easier disposal during recycling, helping to reduce resource waste.   What's more, EVOH is produced in a relatively environmentally friendly manner and does not release harmful substances during its use. Compared to other traditional plastic materials, the use of EVOH reduces the need for chemical additives, further minimizing the impact on the environment. Therefore, EVOH (EVOH EW-3801 & EVAL F101A) is playing an increasingly important role in promoting green packaging and circular economy, becoming an environmentally friendly and sustainable packaging material.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com    

EVOH (Ethylene-Vinyl Acetate Copolymer), is a plastic known for keeping gases out. You’ll often see it in food packaging, medical supplies, and protective gear for cars and electronics. Because it contains a lot of vinyl acetate, it does a great job blocking gases like oxygen and nitrogen, which helps food stay fresh longer.     The reason EVOH is so effective at this is because of its tightly packed structure, which makes it harder for gas molecules to sneak through.  Manufacturers can tweak the hydrolysis level during production, and when they increase it, the molecular chains become tighter, improving its gas-blocking abilities. In China, EVOH products (EW-3201 and EW-3801) produced by Sinopec are highly recognized.     EVOH also stands out from other plastics because it’s resistant to chemicals and high temperatures, plus it’s clear.  It's easy to work with, too, so it can be used in multilayer packaging without complicated processes, making it both practical and afford.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com      

EVOH (ethylene-vinyl alcohol copolymer) is a polymer material produced by copolymerization of ethylene and vinyl alcohol. Since the polar hydroxyl groups on the EVOH molecular chain can form hydrogen bonds with water molecules, it can block moisture, while its non-polar vinyl groups can effectively block gases.   EVOH(EVOH EW-3201) has good processing properties and can be blended or compounded with various plastics such as PE, PP, PET, etc. to produce blended or composite materials with excellent performance. It also has good thermal stability and can be processed at high temperatures. It has excellent transparency, which makes the contents of the package clearly visible and easy for consumers to check. It can be completely recycled and reused, and can also be biodegraded to reduce pollution to the environment. Due to its excellent barrier properties and environmental protection, EVOH is widely used in the field of food packaging. For example, it is widely used in vacuum packaging, food cans, beverage bottles and other fields.   EVOH is also widely used in the field of medical packaging, such as pharmaceutical packaging, medical dressing packaging, etc. Its excellent barrier properties can effectively extend the shelf life of drugs and medical dressings. In addition, EV0H is also widely used in the fields of cosmetic packaging, pesticide packaging, etc.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.
