EVOH Barrier Film matumizi
EVOH filamu ya kizuizi has been the most widely used high barrier material
Filamu ya kizuizi cha EVOH imekuwa nyenzo inayotumika sana ya kizuizi cha juu. Aina hii ya nyenzo za filamu pamoja na aina isiyo ya kunyoosha, kuna njia mbili za kunyoosha, aina ya alumini iliyowekwa na mvuke, aina ya mipako ya wambiso, kunyoosha kwa njia mbili kuna ufungaji sugu kwa bidhaa za kuzaa.
EVOH kizuizi mali kizuizi filamu hutegemea maudhui ya ethilini, kama maudhui ya ethilini kuongezeka kwa ujumla, mali kizuizi gesi kupungua, lakini urahisi wa usindikaji.
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 Filamu ya 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.
