EVOH Barrier Film izicelo
UYOHANE ifilimu yesithintelo has been the most widely used high barrier material
Ifilimu yesithintelo se-EVOH iyeyona nto isetyenziswa kakhulu isithintelo sezinto eziphezulu. Olu hlobo lwezinto zefilimu ukongeza kuhlobo olungelulo, kukho ukunwebeka kweendlela ezimbini, uhlobo lwe-aluminium efakwe ngumphunga, uhlobo lokuncamathelisa, ukolulwa kwendlela ezimbini kukho ukupakishwa kokumelana nobushushu kwiimveliso eziyinyumba.
Ifilimu ye-barrier ye-EVOH yokuthintela ifilimu ixhomekeke kumxholo we-ethylene, njengoko umxholo we-ethylene ukhula ngokubanzi, iimpawu zokuthintela igesi ziyancipha, kodwa ukukhululeka kokucubungula.
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 EVOH film 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.
