Ndi kuwongolera kosalekeza kwa miyezo ya moyo, miyezo yokhwima ya anthu siyimangokhala chakudya chokha. Zofunikira pakuyika kwake zikukweranso. Kuyika chakudya pang'onopang'ono kwakhala gawo lazogulitsa kuchokera kumagawo ake ocheperako. Ndikofunikira kuteteza malonda, Ndikofunikira kwambiri kuthandizira kusungirako ndi mayendedwe, kulimbikitsa malonda, ndikuwonjezera mtengo wazinthu.
Kusindikiza kwa zinthu zomangira za chakudya
① Njira zosindikiziraFood flexible ma CD kusindikizazimachokera ku gravure ndi flexographic kusindikiza, kutsatiridwa ndi makina osindikizira a flexographic kuti asindikize mafilimu apulasitiki (makina osindikizira a flexographic nthawi zambiri amapanga mizere yopangira makina owuma), koma ndi kusindikiza, poyerekeza ndi kusindikiza kwa gravure ndi kusindikiza kwa flexographic komwe kumagwiritsidwa ntchito posindikiza zinthu, pali zosiyana zambiri. Mwachitsanzo: Kusindikiza kwapaketi kosinthika kumasindikizidwa pamwamba pa gawo lapansi lokhala ngati mpukutu. Ngati ndi filimu yowonekera, chitsanzocho chikhoza kuwonedwa kuchokera kumbuyo. Nthawi zina ndikofunikira kuwonjezera utoto wa utoto woyera kapena kugwiritsa ntchito njira yosindikizira yamkati.
② Tanthauzo la njira yosindikizira yakumbuyo Kusindikiza kumbuyo kumatanthauza njira yapadera yosindikizira yomwe imagwiritsa ntchito mbale yosindikizira yokhala ndi chithunzi cham'mbuyo ndi mawu osamutsira inki mkati mwazosindikizira zowonekera, kuti chithunzi chabwino ndi zolemba ziwonetsedwe kutsogolo. wa chinthu chosindikizidwa.
③ Ubwino wa Liyin
Poyerekeza ndi kusindikiza pamwamba, lining printed matter ili ndi ubwino wokhala wowala ndi wokongola, wokongola / wosazirala, wosazindikira chinyezi komanso wosavala. Pambuyo pa kusindikiza kwa lining kuwonjezeredwa, wosanjikiza wa inki umayikidwa pakati pa zigawo ziwiri za filimu, zomwe sizidzaipitsa zinthu zomwe zaikidwa.
Kuphatikizika kwa zinthu zomangika za chakudya
① Njira yophatikizira yonyowa: Valani zomatira zosungunuka m'madzi pamwamba pa zinthu zoyambira (filimu yapulasitiki, zojambulazo za aluminiyamu), phatikizani ndi zinthu zina (mapepala, cellophane) kudzera pa chodzigudubuza, ndiyeno muumitse potentha. kuyanika ngalande Khalani nembanemba gulu. Njirayi ndi yoyenera kunyamula chakudya chowuma.
② Njira yowumitsa: choyamba ikani zomatira zosungunulira mofanana pa gawo lapansi, ndiyeno tumizani ku ngalande yotentha yowumitsa kuti musungunuke bwino zosungunulira, ndiyeno nthawi yomweyo laminate ndi filimu ina. Mwachitsanzo, filimu ya polypropylene (OPP) nthawi zambiri imaphatikizidwa ndi zinthu zina pogwiritsa ntchito njira yowuma yowumitsa pambuyo posindikiza mkati. Zomwe zimapangidwira ndi: filimu ya biaxially oriented polypropylene (BOPP, 12 μm), aluminiyamu zojambulazo (AIU, 9 μm) ndi unidirectional Stretched polypropylene film (CPP, 70 μm). Njira ndi ntchito wodzigudubuza ❖ ❖ kuyanika chipangizo kuti wogawana odula zosungunulira ofotokoza "zouma zomatira ufa" pa zinthu m'munsi, ndiyeno kutumiza kwa otentha kuyanika mumphangayo kuti asungunuke nthunzi zosungunulira pamaso laminating ndi wosanjikiza wina wa filimu ntchito laminating wodzigudubuza.
③ Njira yophatikizira yotulutsa imatulutsa polyethylene yosungunuka ngati nsalu yotchinga kuchokera pang'onoting'ono ya T mold, ndikuyiyika pazitsine, ndikuyiyika papepala kapena filimu kuti zokutira polyethylene, kapena kupereka makanema ena kuchokera pagawo lachiwiri lodyetsa. Gwiritsani ntchito polyethylene ngati zomatira zomangira.
④ Njira yophatikizira yotentha: Polyethylene-acrylate copolymer, ethylene acid-ethylene copolymer, ndi sera ya parafini zimatenthedwa ndikusungunuka palimodzi, kenako zokutira pa gawo lapansi, nthawi yomweyo zimaphatikizidwa ndi zinthu zina zophatikizika kenako kuzikhazikika.
⑤Multi-layer extrusion compounding njira
Mitundu yosiyanasiyana ya ma resin apulasitiki okhala ndi zinthu zosiyanasiyana amadutsidwa kudzera muzotulutsa zingapo ndikutulutsidwa mu nkhungu kuti apange filimu. Izi sikutanthauza zomatira kapena zosungunulira organic pakati pa zigawo, ndi filimu alibe fungo kapena zosungunulira zosungunulira malowedwe, kupanga kukhala oyenera ma CD chakudya ndi yaitali alumali moyo. Mwachitsanzo, mawonekedwe onse a LLDPE/PP/LLDPE ali ndi kuwonekera bwino ndipo makulidwe ake nthawi zambiri ndi 50-60μm. Ngati ili ndi moyo wautali wautali. Zoposa zigawo zisanu za mafilimu apamwamba-zotchinga co-extruded zimafunika, ndipo wosanjikiza wapakati amapangidwa ndi zipangizo zapamwamba zotchinga PA, PET ndi EVOH.
