Piv rau lwm cov yeeb yaj kiab yas, PET zaj duab xismuaj lub zog tensile siab, zoo heev dimension stability, tsis tshua muaj noo noo nqus thiab zoo tuav ntawm lub cev zog tshaj qhov kub thiab txias ntau. Nws kuj muaj UV tiv thaiv zoo heev, hluav taws xob zoo heev, zoo optical clarity, siab gloss thiab zoo gas barrier, tab sis tsuas yog me ntsis noo noo barrier. Nws yog cov yeeb yaj kiab zoo tshaj plaws rau kev luam ntawv zoo thiab lamination, nrog rau cov yeeb yaj kiab yas thiab cov ntawv ua haujlwm siab. Nws muaj qhov siab melting point, ua rau nws tsim nyog rau daim ntawv thov uas yuav tsum tau autoclaving.
Nws feem ntau suav hais tias yog cov yeeb yaj kiab tshwj xeeb vim nws tus nqi siab dua piv rau PVC, PE thiab PP zaj duab xis.
PET tuaj yeem ua tau metalized, uas txhim kho cov roj teeb meem rau cov ntawv thov uas cov khoom lag luam lub neej ntev yog qhov tseem ceeb.PET zaj duab xis yog zoo haum rau ntau yam kev lag luam, hluav taws xob thiab tsheb siv. Nws yog recyclable tag nrho thiab tuaj yeem yooj yim rov ua dua rau hauv ntau lwm yam khoom siv rau ntau yam kev siv. Txawm li cas los xij, tsis zoo li daim ntawv thiab lwm yam khoom siv cellulosic, PET tsis yooj yim decompose. Txawm li cas los xij, biodegradable additives tuaj yeem siv los txhim kho biodegradability ntawm cov yas no yam tsis muaj kev cuam tshuam rau nws lub cev.
Qhov tseem ceeb tshaj plaws polyester zaj duab xis yog biaxially oriented PET los yog BOPET.1 Nws muaj kev tuav zoo ntawm lub cev zoo tshaj qhov kub ntawm qhov dav ntawm kwv yees li ntawm -70 degree mus rau 100 degree piv rau lwm cov yas yeeb yaj kiab.
Txawm hais tias nws tus nqi siab dua, BOPET tau pom ntau daim ntawv thov ntim siab uas xav tau cov yeeb yaj kiab muaj zog dua, qhov ntev ntawm qhov ruaj khov. Qhov teeb meem tseem ceeb ntawm BOPET yog cov nqi tsim khoom ntau dua thiab kev nqis peev ntau dua.
Qhov chaw thov:
PET zaj duab xis feem ntau yog qhov kev xaiv zoo tshaj plaws rau kev thov ntau dua hauv cov ntawv thov zaub mov thiab tsis yog khoom noj khoom haus. Cov khoom siv tseem ceeb muaj xws li lub microwave thiab ntim khoom kho mob, cling zaj duab xis, daim kab xev thaub qab, luam ntawv zaj duab xis, daim npav yas, cov txheej txheem tiv thaiv xws li hnub ci thiab kev ruaj ntseg qhov rais films, tso tawm cov yeeb yaj kiab, transformer rwb thaiv tsev zaj duab xis thiab cov ntawv luam tawm yooj yim. PET kuj tseem siv los ua cov yeeb yaj kiab uas muaj ntxhiab tsw qab (xws li kas fes thiab luam yeeb ntim). Hom zaj duab xis no qee zaum metalized los ntawm vapor deposition ntawm cov hlau, uas ntxiv txhim kho qhov barrier rau oxygen, dej vapor thiab aroma poob.
Ntau yam FDA-qib PET cov khoom tsim nyog rau kev ntim cov ntawv thov vim lawv cov ntxhiab tsw, muaj tshuaj lom neeg thiab inertness.
