Kutheni ukhetha i-PCTG yokwenza ipakethe yokuthambisa ngokwezifiso?

Kwiminyaka yakutshanje, iinkampani ezininzi zokuthambisa ziye zakhetha i-PCTG njengesixhobo sokupakisha imveliso yazo. I-PCTG, okanye i-polybutylene terephthalate, yiplastiki eyenziwe ngezinto eziluhlaza ezihambelana nokusingqongileyo. Kwaye kutheni ukhetha i-PCTG yokwenza ipakethe yokuthambisa ngokwezifiso?

Okokuqala, i-PCTG yimathiriyeli yeplastiki ekwazi ukumelana nobushushu kwaye inokumelana nobushushu. Iyakwazi ukumelana namaqondo obushushu aphezulu kwaye ayikhubazeki lula. Ifanelekileiseti yeebhotile zokuthambisa, ngakumbi ezo mveliso eziqulethe izithako eziphezulu zokushisa.

Okwesibini, i-PCTG inokucaca kakuhle kunye neglosi, ivumela abathengi ukuba babone ngokucacileyo umbala wokwenyani kunye nokuthungwa kwemveliso, ngaloo ndlela benyusa umdla wemveliso.

Ukongeza, izinto ze-PCTG zinokumelana nokugqwala okuthile kunye nokuqina, okunokuqinisekisa ukuba ukupakishwa kwezithambiso akonakali ixesha elide kwaye kwandise ubomi beshelufu yemveliso.

Okokugqibela, i-PCTG yinto ehambelana nokusingqongileyo engaqulathanga i-bisphenol A (BPA) kwaye ihambelana nenkxaso yabathengi bale mihla kunye nokusukela izinto zokupakisha zokuthambisa zokusingqongileyo.

Ukukhetha i-PCTG njengesixhobo sokupakisha izinto zokuthambisa ezilungelelanisiweyo kuhambelana nentsingiselo yamaxesha kwaye kukwaluphawu loxanduva lwenkampani ekuhlaleni.

Ngoko ke, kunokubonwa ukuba kukho izizathu ezininzi zokubaibhotile yokupakisha izithambisoukwenza ngokwezifiso kukhetha i-PCTG njengesixhobo. Ukususela ekusebenzeni kwezinto ukuya kwiimpawu zokukhusela okusingqongileyo, kuhambelana kakhulu neemfuno zeenkampani zokuthambisa zokupakisha imveliso kunye nokusukela abathengi kwiimveliso ezihambelana nokusingqongileyo. Kukholelwa ukuba izinto ze-PCTG ziya kusetyenziswa ngokubanzi kwibala lokupakishwa kwe-cosmetic ngokwezifiso kwixesha elizayo.

I-PCTG yimathiriyeli ekrwada yeplastiki ye-copolyester ecace kakhulu. Inokubonakala okuphezulu, ukuqina okuhle kunye namandla empembelelo, ukuqina kobushushu obuphantsi, ukuxhathisa okuphezulu kweenyembezi kunye nokusebenza kakuhle kokusebenza, kunye nokumelana neekhemikhali okugqwesileyo. Inokucutshungulwa ngeendlela zokubumba zemveli ezinje nge-extrusion, isitofu sokubumba, ukubumba ukuvuthela kunye nokubumba i-blister. Isetyenziswe ngokubanzi kwibhodi kunye neshidi, ifilimu ye-shrink ephezulu yokusebenza, ibhotile kunye neemarike zezinto ezikhethekileyo; ingasetyenziselwa ukuvelisa amathoyizi, izixhobo zendlu kunye nezixhobo zonyango, njl.; idlulile imigangatho yoqhagamshelwano yokutya yase-US FDA kwaye ingasetyenziselwa ukutya, amayeza kunyeingqayi yokupakisha yokuthambisakunye neminye imimandla.
