Ngaba i-thermoforming iyatshintsha ukusebenza komqobo we-blister?

Ewe. I-Thermoforming yolula izinto kwaye inokunciphisa ubukhulu bomaleko ngamnye kwiindonga zecavity kunye neekona. Iimveliso ezibalulekileyo kufuneka zivavanywe kusetyenziswa iphakheji eyiyo yokwenene.

Yeyiphi ifilim ilungele amayeza angevani nokufuma?

Akukho mpendulo jikelele. I-High-PVDC, PC I-TFE-based okanye i-cold-form-aluminiyam izakhiwo zinokuvavanywa xa kufuneka ukuhanjiswa komphunga wamanzi ophantsi kakhulu. Isigqibo sokugqibela kufuneka sisekelwe kwi-chiza-uzinzo kunye ne-packaging-validation data.

Sesiphi isakhiwo esifanelekileyo kwiimveliso ze-oxygen-sensitive?

I-EVOH enezakhiwo ezininzi ze-multilayer ingaba ngabaviwa abomeleleyo apho ukhuseleko lwe-oksijini luyimfuneko ephambili. I-PVDC kunye nezinye izakhiwo ezinomqobo ophezulu nazo zinokuqwalaselwa ngokuxhomekeke kubumanzi, ukubunjwa kunye neemfuno zolawulo.

Ngaba i-EVOH yokupakisha yamayeza inokuphinda isetyenziswe?

Ukuphinda kusetyenziswe kwakhona kuxhomekeke kulwakhiwo olupheleleyo lwe-multilayer, ipesenti ye-EVOH, ezinye iipolymers, imathiriyeli yokugquma kunye nomjelo wokuphinda usebenziseke wendawo. Ubukho be-EVOH bubodwa abubonakalisi ukuba iphakheji yamayeza egqityiweyo iyaphinda isetyenziswe.

Ngaba ifilimu ye-blister yeyeza kufuneka ivavanywe phambi komyalelo wentengiso?

Ewe. Abathengi kufuneka bavavanye ukubunjwa, ukutywinwa, ukuprintwa apho kufanelekileyo, ukuzinza komda, ukuthembeka kwepakethi egqityiweyo kunye nokusebenza komqobo ofunekayo kwisixhobo sokupakisha esicetywayo ngaphambi kwesiqinisekiso sorhwebo.

Khetha iSakhiwo sokuPakisha kwiMfuno yeChiza, hayi igama lePolymer

PVC , i-PVDC, i-EVOH kunye ne-LDPE akufuneki ijongwe nje njengeefilimu ezine zamadyungudyungu ezine ezikhuphisanayo. I-polymer nganye yenza umsebenzi owahlukileyo, kwaye ukupakishwa kwe-multilayer kusebenza ngokudibanisa loo misebenzi kwisakhiwo esihambelana nemveliso yamayeza.

PVC ibonelela ngobungqongqo kunye ne-thermoforming. I-PVDC iphucula ukufuma kunye nesithintelo se-oxygen. I-EVOH ibonelela ngeoksijini eyomeleleyo kunye nokhuseleko lwerhasi kodwa ngokuqhelekileyo ifuna imigangatho engqongileyo ekhusela ukufuma. I-LDPE ibonelela ngokutywinwa kwaye ifake isandla kukhuseleko lokufuma ngaphakathi koyilo lwe-multilayer.

Kwiprojekthi entsha yokupakisha amayeza, unikeze i-Wallis ngesakhiwo sakho sangoku, i-OTR ekujoliswe kuyo kunye ne-WVTR, ubukhulu befilimu, i-geometry ye-cavity, ulwazi lomatshini we-blister, ukucaciswa kwe-lidding, indawo yemozulu kunye nobungakanani obufunekayo ukuze izinto ezifanelekileyo zivavanywe isiqinisekiso sesampulu.
