EVOH Barrier Film Aplicações
EVOH filme barreira has been the most widely used high barrier material
O filme de barreira EVOH tem sido o material de alta barreira mais amplamente utilizado. Este tipo de material de filme, além do tipo não esticado, há estiramento bidirecional, tipo de alumínio depositado por vapor, tipo de revestimento adesivo, estiramento bidirecional, existem embalagens resistentes ao calor para produtos estéreis.
As propriedades de barreira do filme EVOH dependem do teor de etileno, à medida que o teor de etileno aumenta em geral, as propriedades de barreira ao gás diminuem, mas a facilidade de processamento.
Notable feature is EVOH barrier film having excellent gas barrier properties and excellent processability, in addition to transparency, gloss, mechanical strength, flexibility, abrasion resistance, cold resistance and surface strength are very excellent. In the packaging field, EVOH barrier layer made of composite membrane intermediate, used in all of the hard and soft packaging; for aseptic packaging in the food industry, hot pot and cooking bags, packaging dairy products, meat, canned fruit juices and seasoning; non-food products, packaging for solvents, chemicals, air-conditioned structure, lined with barrels of gasoline, and other electronic components. In food packaging, EVOH plastic container can replace glass and metal containers, domestic aquaculture companies export seafood on the use of PE / EVOH / PA / RVOH / PE five-layer co-extruded film vacuum packaging. Accelerating the EVOH composite membrane while also studying abroad EVOH stretch orientation, the new gas barrier properties of filme EVOH is three times the performance of existing non-stretched EVOH film. In addition EVOH as a barrier material can also be coated on the other synthetic resin packaging materials, serve to strengthen the effect of barrier properties.
