Imfuno yokutya okulula, okulungele ukutyiwa iye yanda kwiminyaka yakutshanje. Ngenxa yoko, ukupakishwa kokutya kudlala indima ebalulekileyo ekuqinisekiseni ukuba oku kutya kukhuselekile, kutsha, kwaye kuyathandeka emehlweni. Ngena CPET trei , isisombululo sokupakisha esiphucula ishishini lokutya okulungiselelweyo.

Intshayelelo kwi Trei za chakula za CPET CPET trei , okanye iCrystallized Polyethylene Terephthalate trei , zizisombululo ezintsha zokupakisha ukutya. Ziye zathandwa kakhulu ngenxa yokuguquguquka kwazo, ukuqina kwazo, kunye nokuzinza kwazo. Kweli nqaku, siza kungena kwihlabathi le CPET trei kwaye sihlolisise

Kwihlabathi lanamhlanje elikhawulezayo, ukulula kunye nokuguquguquka kubalulekile ekupakisheni imveliso. Enye yezinto eziye zathandwa kakhulu ngenxa yeenzuzo zayo ezininzi yi CPET (Crystalline Polyethylene Terephthalate). Kweli nqaku, siza kuthetha CPET trei kunye nokusetyenziswa kwazo okwahlukeneyo, iingenelo, kunye nemizi-mveliso.

PET sisifinyezo sesiNgesi esithi Polyethylene terephthalate. Lithetha iiplastiki ze-polyethylene terephthalate, eziquka ikakhulu i-polyethylene terephthalate PET kunye ne-polybutylene terephthalate PBT. I-Polyethylene terephthalate ikwabizwa ngokuba yi-polyester resin. PET isakhiwo seplastikiI-molecular str

Yintoni umahluko phakathi kokuprinta kwe-offset nokuprinta kwedijithali? Ukuprinta kwe-offset kwenziwa kwiprinta kusetyenziswa iipleyiti zokuprinta kunye ne-inki emanzi. Olu hlobo lokuprinta luthatha ixesha elide ukuvelisa kuba kukho ixesha lokuseta elingakumbi kwaye imveliso yokugqibela kufuneka yomiswe ngaphambi kokuba igqitywe. Kwangaxeshanye, o

I- CPET yinto enobuhlobo nokusingqongileyo eyenziwe nge-polyethylene terephthalate, engenavumba, engenancasa, engenambala, ebolayo, kwaye engenatyhefu. I- CPET le nto ibonwa njengeyona nto ilungileyo yokupakisha ukutya kwihlabathi liphela namhlanje. I- CPET le nto idlula kwiinkqubo ezithile zemveliso ekhethekileyo - iBlister pr

Yintoni kanye kanye into yeplastiki ye PVC ? PVC , igama elipheleleyo yiPolyvinylchloride, into ephambili yipolyvinyl chloride, kwaye ezinye izinto zongezwa ukuphucula ukumelana nobushushu bayo, ukuqina, ukuguquguquka, njl. Iileya ezintathu ze PVC nyenzo za karatasi Umaleko ophezulu we PVC yilacquer, into ephambili ephakathi.

Njengenxalenye ebalulekileyo yefomula yeemveliso eziguquguqukayo ze- PVC , i-plasticizer inempembelelo enkulu ekusebenzeni kweemveliso eziguquguqukayo ze- PVC . Ukuba iimveliso ezithambileyo ze- PVC ( PVC iikhethini zomnyango wokugcina ubushushu) ziyafuneka ukuba zisetyenziswe kumaqondo obushushu aphantsi, ii-plasticizer ezinokumelana kakuhle nobushushu kufuneka zikhethwe.

Ibhodi yefoam ye PVC yinto entsha yeplastiki ekhaphukhaphu, ene PVC njengesixhobo esiphambili. Ibhodi yefoam ye PVC yenziwe ngeenkqubo ezikhethekileyo zokukhupha amagwebu, ezifana nefoam ekhululekileyo okanye i-celuka. Ibhodi yefoam ye PVC ayifumi, ayizicimi, ayiguquguquki, ayinatyhefu, inamandla okulwa nokwaluphala. Okwangoku, ine-e

I-DOP kunye ne-DOTP ziiplastiki ezisetyenziswa ngokubanzi ezisetyenziselwa ukwenza PVC ithambe, iguquguquke kwaye kube lula ukuyicubungula. Umahluko ophambili kukwakheka kwazo kweemolekyuli: I-DOP, edla ngokubhekisa kwi-DEHP, yi-orthophthalate, ngelixa i-DOTP, ekwabizwa ngokuba yi-DEHT, yi-terephthalate kwaye idla ngokukhethwa njengenye indlela engeyiyo i-orthophthalate.

Zininzi iintlobo zezinto zeplastiki ezifumanekayo kushishino lokupakisha. Xa ufuna ukupakisha iimveliso zakho, ungafumanisa kungekudala izinto ezimbini zeplastiki ezisetyenziswa rhoqo: PET kunye nezinto zeplastiki PVC KwiHuisuqinye Plastics Group, abathengi bahlala besibuza ukuba zeziphi izinto zeplastiki eziye zangqineka zilungile.
