EVOH Barrier Film Aplikasi
EVOH film penghalang has been the most widely used high barrier material
Film penghalang EVOH telah menjadi bahan penghalang tinggi yang paling banyak digunakan. Jenis bahan film ini selain jenis non-stretched, ada stretch dua arah, tipe aluminium yang diendapkan uap, tipe coating perekat, stretch dua arah ada kemasan tahan panas untuk produk steril.
Film penghalang sifat penghalang EVOH tergantung pada kandungan etilena, karena kadar etilena meningkat secara umum, sifat penghalang gas berkurang, tetapi kemudahan pemrosesan.
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 film EVO 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.
