EVOH is a crystalline polymer with a chain structure, which integrates the good processability of ethylene polymer and the extremely high gas barrier of vinyl alcohol polymer. It is a new barrier material. Its gas barrier is 100 times higher than PA (polyamide), 10000 times higher than PE and PP, and more than ten times higher than PVDC (polyvinylidene chloride).
In addition, EVOH has excellent transparency, gloss, mechanical strength, flexibility, wear resistance, cold resistance and surface strength. At the same time, EVOH has the highest thermal stability among high-performance barrier resins. This property makes the waste produced in processing reusable.
The multi-layer extruded composite film made of ordinary plastics and high barrier plastics can not only significantly improve the barrier performance, but also help to play the role of each component, and obtain a film with good comprehensive performance and low cost.
EVOH, as a high barrier material, is often extruded with a variety of resins in multiple layers and is used for the packaging of beverages, dairy products, fruit juices, beverages, and a variety of foods. For example, at present, many domestic aquatic products companies export seafood with PE/TIE/EVOH/PA/EVOH/TIE/PE seven-layer coextrusion membrane vacuum packaging.
EVOH has always been the most widely used high barrier material. In addition to the non-stretching type, the film type of this material also includes the biaxial stretching type, aluminum evaporation type, adhesive coating type, etc. Among the biaxial stretching type, there are heat-resistant types for aseptic packaging products.
The barrier performance of EVOH depends on the ethylene content. Generally speaking, when the ethylene content increases, the gas barrier decreases, but it is easy to process.
EVOH is characterized by an excellent gas barrier and excellent processability. In addition, it has excellent transparency, gloss, mechanical strength, scalability, wear resistance, cold resistance and surface strength.
GWELL as China Plastic Extruder Supplier, EVOH multi-layer film extrusion line continues the previous advantages of high output and low energy consumption, and at the same time, it keeps pace with the times and has a higher cost performance.
Since its establishment, China GWELL has been focusing on the R&D and production of plastic sheet extrusion production equipment. In the continuous innovation practice, the extrusion equipment has been improved to make the performance better and the structure more user-friendly.
