I-PVC eqinile isho ukuntuleka kwezithako zokuthambisa kanye namapulasitiki efilimu le-PVC elakha. Ngaphandle kwamapulasitiki, Ama-bvc blister ahlinzeka ngokuqina kwesakhiwo & ukuzivikela ngokomzimba kwefomu lomthamo. I-blister cavity kufanele ihlale ifinyeleleka ukuze kugcinwe umphumela we-push-through, futhi iwebhu ekhiqiziwe akumele ibe nzima kakhulu ukugoqa lapho icindezelwa. Ngenxa yalokho, kuye ngobukhulu kanye nokuma komgodi, ubukhulu beshidi le-PVC 200 ku 300 yiyona evame kakhulu.

I-PVC Foil noma i-PVDC Foil Ngezinjongo Zokwelapha?

-Petekayo I-PVC foil ekhemisi kuyinto esobala, eqinile, kanye nezinto eziphansi ze-WVTR. Ngaphezu kwe-thermoformability yayo evelele, amandla e-flexural, kanye nokumelana kwamakhemikhali, le nto inokumelana okungekuhle kumafutha, amafutha, noma izingxenye zokunambitheka, uzinzile, futhi ayibizi. I-PVC eqinile iyimpahla engcono kakhulu yokupakishwa kwamabhamuza ngenxa yalezi zimfanelo, futhi iphethe i-monopoly emakethe yezingxenye zepulasitiki. Ugqinsi lwamafilimu e-PVC enziwe nge-thermoformed azungezile 10 mil. I-PVC ibonakala ine-ecological connotation eyingozi ngenxa yokuqukethwe kwayo kwe-chlorine nama-dioxin anobuthi obukhulu.. Izithiyo eziyinhloko yisithiyo esimpofu ekungeneni komswakama kanye nokungena kwe-oxygen.

Amabhamuza emithi ngokuvamile asebenzisa amashidi e-PVC ane 250 noma 0.250 ubukhulu mm. Amazinga Okudlulisa Umhwamuko Wamanzi (Wvtr) kanye Nezinga Lokudluliswa Kweoksijini (OTR) kwe a 250 Ifilimu ye-PVC ngokuvamile iseduze 3.0 g/m2/ngosuku ku-38°C/90% RH futhi cishe 20 cc/m2/ngosuku, ngokulandelana. Ifilimu ye-PVC ingambozwa kusetshenziswa i-PVDC noma iboshelwe ku-PCTFE kanye ne-COC ukuze iqede ukuntuleka kwayo kwezimfanelo zokuvimbela. Okokufaka amabhamuza okwelapha, Amafilimu amabhamuza anezingqimba eziningi asuselwa ku-PVC avame ukusetshenziswa, nge-PVC esebenza njengomgogodla wokuxilonga wesakhiwo. Izihlungi ze-Pigments ne-UV zingasetshenziswa ukufaka umbala kungqimba lwe-PVC.

ukupakishwa kwe-foil yezokwelapha

Ipulasitiki efakwe ngaphakathi I-PVDC foil (Polyvinylidene chloride). Ukupakishwa kwama-blister kuncike kakhulu ekukhanyeni kwe-PVDC kanye nama-coatings ku-PVC. Ukunciphisa ukungena kwamaphasela e-PVC amabhamuza kugesi kanye nomswakama kungafinyelelwa ngokusebenzisa i-PVDC.. Ijazi le-PVDC liwugqinsi oluyi-1-2 mil, kuyilapho amafilimu e-PVC embozwe ewugqinsi ongu-8–10 mil. Ngakolunye uhlangothi, imikhiqizo kanye nezinto zokuvala kuvame ukuthintana ne-coating.

Izinketho nokucatshangelwa ngokuya ngezinto zokwakha

Ipulasitiki nama-polymers, kuhlanganise HDPE, I-LDPE, I-PET, I-PVC, kanye ne-PP, yizinto ezisetshenziswa kakhulu emaphaketheni emithi. Kungenzeka ukwenza izitsha, amabhodlela, imijovo, namabhamuza anepulasitiki ngenani eliphansi futhi kalula. Ingase yenziwe i-laminated ngezinsimbi ezifana ne-aluminium ukudala ukupakisha okuguquguqukayo.

Isidingo sokukhanya somkhiqizo, ukushisa, kanye nokuvikela umswakama kubeka uhlobo lwezinto zokupakisha ezisetshenziswayo. Impilo yeshelufu yesidakamizwa & izimo zokugcina zizothinteka ukumelana kwezinto ezibonakalayo kuzo zonke lezi zici. Izifundo zokuzinza komuthi ngokuvamile zenziwa ngesikhathi sokuthuthukiswa ukuze kunqunywe ukuthi yiziphi izinto ezisetshenziswayo ezifanele kakhulu uma kubhekwa izindleko ezihlukahlukene ezihilelekile..

Ukupakishwa kwamabhamuza ngaphakathi embonini yezemithi kubalulekile.

Ukupakishwa kuyingxenye ebalulekile yokulethwa kwezidakamizwa okunjalo kanye nethuluzi elibalulekile lokumaketha. Amafemu amakhemikhali aya ngokuya athembela emaphaketheni azo ukuze avikele futhi adayise imithi yawo njengoba izimakethe zikhula., izidingo zekhasimende ziyathuthuka, kanye nezimfuneko zokulawula ziyashintsha. Umumo wephakethe lamabhamuza unezinzuzo ezimbalwa ezihambisana nezidingo zemboni ye-pharma namuhla. Ngenxa yalokho, amaphasela asephenduke futhi azoqhubeka nokuba yizinketho zokulebula ezidume kakhulu nezikhula ngokushesha embonini yezemithi..

Izinhlobo zokupakisha amabhamuza

I-PVC, I-PCTFE, I-PVDC, kanye namabhamuza e-thermoform, ngezidakamizwa ezingazweli kakhulu, noma I-aluminium foil ye ukubekwa kwe-blister, ukuze uthole Izithako Zemithi Ezisebenzayo ezibucayi (Ama-API), ezimbalwa kuphela zezinketho ezitholakalayo ekufakweni kwamabhamuza.

• Manje kunezinhlobo ezimbili eziyinhloko zokupakishwa kwamabhamuza ezisetshenziswa embonini yezemithi. Phakathi kwazo:
• Ukwakha umgodi, ipulasitiki ye-thermoformed isetshenziswa, kuyilapho isivalo senziwe ngepulasitiki noma ukuxuba izinto eziningi.
• Ukwelula okubandayo kusetshenziselwa ukwakha umgodi ohlotsheni lwesibili, okuhlanganisa i-foil njengengxenye eyinhloko yakho kokubili amawebhu kanye namawebhu ngokwawo.

Ukuqhathaniswa kwe-thermal kanye ukwakha okubandayo

Iningi lokukhula kwemakethe livela kumaphakethe we-thermoformed blister, ezinesabelo esikhulu kunazo zonke. I-PVC, I-PVDC (i-PVC ehlanganisiwe), PP, I-PET, I-ACLAR, futhi ama-COC angamafilimu okwakha epulasitiki asetshenziswa kakhulu (i-cyclo-olefin copolymers).

Enye indlela yokwenza iphakethe le-blister kubanda ukwakha ishidi elisekelwe ku-aluminium libe yisimo oyifunayo (I-OPA-ALU-PVC). Ukupakishwa kwebhamuza le-Alu Alu kuvumela cishe ukufinyeleleka okuphelele komhwamuko wamanzi, okwenza kube inqubo enzima futhi ebiza kakhulu kune-thermoforming yezinto ezizwela kakhulu umswakama. Amabhamuza enziwe nge-aluminium abiza kakhulu kunalawo enziwe nge-PVC, futhi lokhu akubangelwa nje kuphela izindleko eziphakeme ze-aluminium njengento eluhlaza. Ukwakheka okuphansi kwe-laminate foil kubangela imigodi emikhulu kunesidingo somkhiqizo, okuphakamisa izindleko iphakethe ngalinye. Kuzokwenyuka izindleko zesibili zokupakisha nezokuthutha ngenxa yalokhu.

Ihlobo

Nokho, imboni yezemithi ikhulisa ukusetshenziswa kwayo kokupakisha njengendlela nje yokumaketha ngenxa yokwanda kwemithi ejwayelekile ye-OTC kanye nemakethe enokuncintisana kakhulu.. Kukhona nesidingo semiklamo ekhuthaza ukuthotshelwa kwesiguli, ukubhekana nokuphikiswa kwezingane, noma uvimbele ukwenziwa komgunyathi ngandlela thize.
