Co-extruded zaj duab xis yog siv rau hauv cov hnab mis ntshiab, cov hnab nthuav qhia, thiab cov yeeb yaj kiab hlau tiv thaiv. Nws yog characterized los ntawm zoo tensile zog thiab zoo nto brightness.https://www.wenxipacking.com/functional-film/food-packaging-film/environmentally-friendly-co-extruded.html
Hauv kev ua cov yeeb yaj kiab, cov khoom siv raw yog extruded mus rau lwm cov yeeb yaj kiab uas tau ua, lossis cov yeeb yaj kiab ntawm ntau yam uas tau ua los yog sib koom ua ke los ua ntau txheej txheej. Cov khoom no yog hu ua zaj duab xis sib xyaw. Feem ntau ntawm cov khoom siv zaj duab xis yog yas, tab sis daim ntawv, hlau ntawv (feem ntau yog txhuas) los yog ntaub kuj siv tau. Lub hauv paus yuav tsum tau ntawm co-extruded zaj duab xis manufacturers yog kom muaj zoo heev adhesion ntawm cov khaubncaws sab nraud povtseg los xyuas kom meej tag nrho cov neeg kho tshuab zog ntawm pob.
Tsis tas li ntawd, cov yeeb yaj kiab sib xyaw feem ntau yog siv rau kev ntim khoom noj, thiab cov nplaum nplaum yog siv rau hauv kev ua ntawm co-extruded film manufacturers, thiab kev xaiv cov kuab tshuaj thiab cov txheej txheem sib txuas yuav tsum ua raws li cov qauv kev tu cev. Cov yeeb yaj kiab co-extruded muaj feem ntau ntawm cov yam ntxwv ntawm cov yeeb yaj kiab sib xyaw, tab sis muaj qhov sib txawv, uas yog, txhua txheej ntawm cov yeeb yaj kiab co-extruded yog extruded tib lub sijhawm, yog li yuav tsis muaj lwm yam khoom tsis yog yas xws li. raws li aluminium ntawv ci thiab ntawv. Kev sib xyaw ua ke ntawm cov khoom siv yog qhov me me, thiab cov peev txheej ntawm daim ntawv thov kuj yog me me. Txawm li cas los xij, vim tias lub caij ntuj no sib txuas txheej thiab txheej yog sib txuas los ntawm kub yaj yam tsis muaj nplaum, kev nyab xeeb kev nyab xeeb ntawm co-extruded zaj duab xis rau ntim khoom noj yog qhov txhim khu kev qha.
Kev ua haujlwm co-extruded films tuaj yeem siv los hloov qee cov qauv co-extruded film manufacturers. Piv txwv li, cov yeeb yaj kiab sib xyaw nrog PA / PE hauv nruab nrab txheej tuaj yeem hloov tau los ntawm PA / PE co-extruded zaj duab xis; Cov zaj duab xis sib xyaw nrog cov qauv rwb thaiv tsev siab tuaj yeem hloov tau los ntawm EVOH-muaj co-extruded zaj duab xis Hloov chaw, tshwj xeeb tshaj yog rau cov khoom siv rwb thaiv tsev siab xws li kua txiv hmab txiv ntoo, ketchup, jelly, thiab lwm yam., cov khoom siv co-extruded film yog siv rau ntim, uas tuaj yeem tiv thaiv cov khoom tsis muaj xim thiab tsw.
