Wallis inopa PVC/EVOH/LDPE yakakwira-barrier rigid sheet yemishonga, yekurapa, yekuongorora, inovaka muviri uye yakakosha yehutano hwekurongedza maapplication. Iyo multilayer dhizaini inosanganisa yakasimba PVC yekugadzira layer, EVOH oxygen-barrier layer uye LDPE sealing layer kuti ipe chiyero che thermoforming performance, gasi kuchengetedza uye kupisa-chisimbiso kushanda.
Izvo zvinhu zvinogona kupihwa mumipumburu kana pre-akachekwa mapepa ane akajairwa ukobvu, hupamhi, ruvara, opacity uye layer yekuvaka. Inogona kuongororwa for thermoformed cavities, rigid trays, unit-dose packaging, diagnostic reagent packaging uye mamwe akashandurwa ekurongedza mafomati.
Pamishonga yemishonga uye yezvokurapa, kusarudzwa kwezvinhu zvekupedzisira kunofanira kunge kwakavakirwa pachiyero chinodiwa chekufambisa okisijeni, chiyero chekufambisa kwemvura-mhute, kuumba kudzika, kuisa chisimbiso, kugadzirwa kwepakeji, kugadzirwa kwesterilization uye zvinodiwa-kutengesa musika zvinodiwa. Kufanirwa kwemuviri kwepakeji yakazara inokurudzirwa pamberi pekugadzirwa kwekutengesa.
Iyo multilayer yekurongedza chimiro inosanganisa akasiyana mapolymer nekuti hapana chinhu chimwe chete chinopa optimum rigidity, oxygen barriers, kuchengetedzwa kwemwando, kuisa chisimbiso uye kugadzirisa kuita kwese application.
PVC inoumba iyo yekutanga yakaoma kana semi-yakaomarara dhizaini. Inopa kugadzikana kwedimensional uye inotsigira kudziyisa, kuumbwa kwegomba, kucheka uye mamwe ekurongedza-shanduko maitiro.
EVOH inonyanya kusarudzwa nekuda kweokisijeni yayo yakaderera uye gasi permeability. Kubatanidza iyo yakatetepa EVOH barrier layer inogona kuvandudza zvakanyanya mashandiro eoxygen-barriers yepasuru yakawanda kana ichienzaniswa neyakajairwa commodity polymers.
EVOH barrier performance inokanganiswa nehumidity, saka EVOH layer inowanzochengetedzwa mukati meiyo multilayer chimiro pane kushandiswa seyakafumurwa mwando-barrier layer.
LDPE inogona kushanda sechisimbiso chivharo uye inogona kubatsira kuchengetedza EVOH barriers kubva mukunyorovesa. Iyo yekupedzisira mwando-inovharira kuita kunoenderana neLDPE ukobvu, iyo yakazara laminate chimiro uye mamiriro ezvakatipoteredza anoshandiswa kuyedza.
Hwaro hunotevera hunomiririra yazvino yeWallis chigadzirwa renji. Kushivirira kwekupedzisira, layer ratios uye mashandiro anoshanda anofanirwa kusimbiswa kune yega yega yekurapa kana yemishonga yekurongedza chirongwa.

Oxygen chipingamupinyi uye mwando chipingamupinyi zvakasiyana kurongedza zvivakwa uye zvinofanirwa kutsanangurwa zvakasiyana. Chinhu chinotsanangurwa zviri nyore se 'high barrier' hachipi ruzivo rwakakwana rwehunyanzvi pakusarudza mapakeji emishonga.
EVOH inoshandiswa zvakanyanya nekuda kwekupokana kwayo neokisijeni uye kumwe kutapurirana gasi. Izvi zvinogona kuve zvakakosha kune zvigadzirwa zvinogona kukanganisa oxidative.
EVOH pachayo inonzwa nekunyorova. LDPE uye mamwe akatenderedza polymer akaturikidzana anobatsira kupatsanura EVOH kubva mumvura uye kubatsira kune yakazara mwando-kuvharira kuita kweiyo yapera laminate.
Yakanyanya hygroscopic mishonga yemishonga inogona kuda yakasimba mvura-mhute dziviriro kupfuura yakajairwa PVC/EVOH/LDPE chimiro chinogona kupa. Zvichienderana nekugadzikana kwedata, PVDC-, PCTFE- kana imwe nyanzvi yepamusoro-munyoro-inodzivirira kuvaka ingada kuongororwa.
OTR inoyera okisijeni kupenya kuburikidza nekurongedza chimiro pasi pemamiriro akatsanangurwa. Vatengi vanofanirwa kupa iyo yavakatariswa kukosha pamwe chete nekuyedza tembiricha, hunyoro hunyoro, nzvimbo yekuyedza uye inoshanda nzira.
WVTR inoyera kutapurirana kwemvura-mhute uye inofanira kutaurwa yakazvimiririra kubva kuOTR. Inodiwa WVTR zvinoenderana nekunzwa kunyorova kwechigadzirwa uye inotarisirwa kuchengetedza nharaunda.
OTR neWVTR tsika dzinogona kushanduka zvakanyanya nekupisa, hunyoro uye ukobvu hwezvinhu. Saka kukosha kwemupi kunofanirwa kuenzaniswa chete kana mamiriro ebvunzo akaenzana.
Thermoforming inotambanudza iyo multilayer zvinhu uye inoderedza ukobvu hwehuputi pamadziro emadziro nemakona. Pamashandisirwo akaomarara, mashandiro ezvipingamupinyi anofanirwa kuongororwa pasuru yakaumbwa pamwe nepapepa rekutanga rakafuratira.
Iyo EVOH layer inoderedza zvakanyanya kupfakanyika kweokisijeni kana ichienzaniswa neyakajairwa commodity polymer zvimiro uye inogona kutsigira kurongedza kwekugadzira zvigadzirwa zvinonzwa oksijeni.
PVC inopa yakagadzika dhizaini ye thermoforming, inobatsira kugadzira akaomesesa cavities, matireyi uye zvimwe zvakashandurwa zvekurongedza zvinhu.
Iyo LDPE layer inogadzira inoshanda sealant pamusoro uye inogona kuenzaniswa kune yakakodzera lidding kana mating zvimiro mushure mekuyedzwa chisimbiso.
Transparent zvimiro zvinogona kupa chigadzirwa kuoneka uku uchichengetedza EVOH oxygen-barrier layer. Rudzi uye opaque shanduro dzinogona zvakare kukurukurwa kune mapurojekiti anoda akasiyana ekuona chitarisiko.
Ukobvu hwakazara uye huyero hwega hwega hunogona kuyerwa zvichienderana nekuoma kunodiwa, barriers level, cavity geometry, yekuisa chisimbiso uye maitiro ekushandura.
Kupisa-chisimbiso kushanda kunoenderana neyakakwana yekuisa chisimbiso system. LDPE inogona kupa inoshanda sealant layer, asi kusimba kwechisimbiso hakugone kufanotaurwa kubva pazita repolymer chete.
Vatengi vanofanirwa kupa iyo chaiyo aluminium foil, laminated firimu, peelable lidding kana imwe mating magadzirirwo nekuti akasiyana sealants uye machira anoda akasiyana mamiriro.
Chisimbiso chekutanga tembiricha, nguva yekugara, kudzvanywa uye kumhanya kwemutsara kunofanirwa kugadzikwa uchishandisa chaiyo yekurongedza muchina uye yekuvharisa zvinhu.
Akapedzwa mapakeji anofanirwa kutariswa kuti ane chisimbiso simba, chiteshi, kuvuza uye kutendeseka pasi pekutarisirwa kwekufambisa uye kuchengetedza mamiriro.
PVC/EVOH/LDPE inogona kugadziridzwa kurongedza thermoformed, asi iyo yakazara layer yedhizaini inofanirwa kuongororwa pasi pezvakatarisirwa kuumba mamiriro.
Mamiriro ekupisa anofanirwa kubvumidza yakakwana PVC kuumba uku uchidzivirira kukuvadzwa kune laminate interface kana zvakanyanya kukanganisa chikamu chakapedzwa.
Yakadzama cavities inogadzira yakakura kutambanudza zvinhu. Ipa hupamhi hwemhango, kureba, kudzika uye kona geometry paunenge uchiongorora itsva multilayer yakatarwa.
Zvigadzirwa zvakakosha zvinonzwa okisijeni zvinofanirwa kuongororwa uchishandisa yakaumbwa-package barriere test nekuti ukobvu hweEVOH hunogona kusiyanisa mugomba mushure mekutambanudza.
Iyo laminate inofanirwa kuongororwa mushure mekugadzirwa kwekupatsanurwa kwemukati, kuchena, kutsemuka kana imwe shanduko yemaitiro isati yabvumirwa kutengeserana.
PVC/EVOH/LDPE inogona kuongororwa mahwendefa, capsules uye zvimwe zvakasimba-dosage zvigadzirwa uko okisijeni kudzivirira, kuumba maitiro uye chisimbiso kuvimbika kwakakosha. Zvigadzirwa zvinonzwa kunyorova zvakanyanya zvinofanirwa kuongororwa zvakaparadzana zvichitarisana nemasimba akasimba anodzivirira mwando.
Diagnostic reagents uye bvunzo zvikamu zvinogona kubatsirwa neokisijeni-barrier packaging, asi kuenderana kunofanirwa kusimbiswa neiyo chaiyo reagent kuumbwa, yekubata layer uye inochengeterwa mamiriro.
Yakasarudzwa mvura kana unit-dose kurongedza zvikumbiro zvinogona kuongororwa uko iyo LDPE yekubatanidza layer, chisimbiso dhizaini uye kuenderana kwekemikari kwakakodzera kugadzirwa.
Iyo yakaoma multilayer chimiro inogona kuongororwa kune yekurapa kana yehutano tireyi inoda thermoforming uye oxygen-barrier performance. Sterile yekurapa-mudziyo kurongedza inoda kwakasiyana hunhu hwepakeji yakazara uye sterilization maitiro.
Oxygen-sensitive mavhitaminzi, supplements uye nutraceutical formulations vanogona kuve vakwikwidzi veEVOH-based packaging kana iyo yakazara chipingamupinyi yakatarwa ichienderana nezvinodiwa-kugadzikana kwechigadzirwa.
