Ukudla okunomsoco kwezemidlalo yigama elijwayelekile, elihlanganisa imikhiqizo eminingi ehlukene kusukela ku-protein powder kuya kwezinti zamandla kanye nemikhiqizo yezempilo. Ngokwesiko, i-protein powder kanye nemikhiqizo yezempilo ipakishwa emiphongolweni yepulasitiki. Muva nje, inani lemikhiqizo yokudla kwezemidlalo enezixazululo ezithambile zokupakisha liye landa. Namuhla, ukudla okunomsoco kwezemidlalo kunezixazululo ezihlukahlukene zokupakisha.
Isikhwama sokupakisha esinesikhwama samaprotheni sibizwa ngokuthi i-flexible packaging, esebenzisa kakhulu izinto ezithambile, njengephepha, ifilimu, i-aluminium foil noma ifilimu eyenziwe ngensimbi. Wake wazibuza ukuthi yini ukupakishwa okuguquguqukayo kwesikhwama samaprotheni enziwe? Kungani iphakethe ngalinye eliguquguqukayo lingaphrintwa ngamaphethini anemibala ukuze likuhehe ukuthi uthenge? Okulandelayo, lesi sihloko sizohlaziya ukwakheka kokupakishwa okuthambile.
Izinzuzo zokupakisha eziguquguqukayo
Ukupakisha okuguquguqukayo kuyaqhubeka nokuvela ezimpilweni zabantu. Inqobo nje uma ungena esitolo esithenga izinto kalula, ungabona ukupakishwa okuguquguqukayo ngamaphethini ahlukahlukene nemibala emashalofini. Ukupakisha okuguquguqukayo kunezinzuzo eziningi, yingakho kungasetshenziswa ezimbonini eziningi ezahlukene, njengemboni yokudla, imboni yezogesi, imboni yobuhle bezokwelapha, izimboni zansuku zonke zamakhemikhali nezimboni.
1. Ingakwazi ukuhlangabezana nezidingo zokuvikela ezihlukene zempahla futhi ithuthukise impilo yeshelufu yempahla.
Ukupakisha okuguquguqukayo kungenziwa ngezinto ezihlukene, ngayinye enezici zayo zokuvikela umkhiqizo kanye nokwenza ngcono ukuphila kwayo isikhathi eside. Imvamisa, ingahlangabezana nezidingo zokuvimba umhwamuko wamanzi, igesi, amafutha, isincibilikisi esinamafutha, njll., noma i-anti-rust, i-anti-corrosion, i-anti-electromagnetic radiation, i-anti-static, i-anti-chemical, inyumba kanye nentsha, engeyona ezinobuthi futhi ezingangcolisi.
2. Inqubo elula, kulula ukuyisebenzisa nokuyisebenzisa.
Lapho wenza ukupakisha okuguquguqukayo, inani elikhulu lokupakisha okuguquguqukayo lingakhiqizwa inqobo nje uma kuthengwa umshini onekhwalithi enhle, futhi ubuchwepheshe busebenza kahle. Kubathengi, ukupakishwa okuguquguqukayo kulula ukusebenza futhi kulula ukukuvula nokudla.
3. Ilungele ukuthengiswa, ngokukhanga okuqinile komkhiqizo.
Ukupakisha okuguquguqukayo kungathathwa njengendlela yokupakisha efinyeleleka kakhulu ngenxa yokwakhiwa kwayo okungasindi nokuzwakala kwesandla okunethezekile. Isici sokuphrinta imibala emaphaketheni siphinde senze kube lula kubakhiqizi ukuveza ulwazi lomkhiqizo nezici ngendlela ephelele, eheha abathengi ukuthi bathenge lo mkhiqizo.
4. Izindleko eziphansi zokupakisha kanye nezindleko zokuhamba
Njengoba iningi lokupakishwa okuguquguqukayo lenziwe ngefilimu, impahla yokupakisha ithatha indawo encane, ukuthutha kulula kakhulu, futhi izindleko eziphelele ziyancipha kakhulu uma kuqhathaniswa nezindleko zokupakisha okuqinile.
Izici zama-substrates okupakishwa okuguquguqukayo
Iphakethe ngalinye eliguquguqukayo livame ukuphrintwa ngamaphethini nemibala eminingi ehlukene ukuheha abathengi ukuthi bathenge umkhiqizo. Ukuphrinta kokupakishwa okuguquguqukayo kuhlukaniswe ngezindlela ezintathu, okuwukuthi ukuphrinta kwendawo, ukuphrinta kwangaphakathi ngaphandle kokuhlanganisa kanye nokuhlanganisa ukuphrinta kwangaphakathi. Ukuphrinta okungaphezulu kusho ukuthi uyinki uphrintiwe endaweni engaphandle yephakheji. Ukuphrinta kwangaphakathi akuhlanganisiwe, okusho ukuthi iphethini iphrintiwe ohlangothini lwangaphakathi lwephakheji, okungenzeka ukuthi ixhumene nephakheji. Isendlalelo esiyisisekelo sokupakishwa kwezinto eziyisisekelo esiyinhlanganisela nokuphrinta siyahlukaniswa. Ama-substrates ahlukene okuphrinta anezici zawo ezihlukile futhi afanele izinhlobo ezahlukene zokupakisha eziguquguqukayo.
1. I-BOPP
Ku-substrate yokuphrinta eguquguqukayo evamile kakhulu, akufanele kube nemigodi emihle ngesikhathi sokuphrinta, ngaphandle kwalokho kuzothinta ingxenye yesikrini engashoni. Ukunakekela okukhethekile kufanele kukhokhwe ekuncipheni kokushisa, ukushuba kobuso kanye nokushelela kwendawo, ukushuba kokunyathelisa kufanele kube okumaphakathi, futhi izinga lokushisa lokoma kufanele libe ngaphansi kuka-80 °C.
2. I-BOPET
Ngenxa yokuthi ifilimu ye-PET ivamise ukuba mncane, idinga ukushuba okukhulu ukuze yenziwe ngesikhathi sokunyathelisa. Ohlangothini lukayinki, kungcono kakhulu ukusebenzisa uyinki ochwepheshe, futhi okuqukethwe okuphrintwe ngoyinki ovamile kulula ukususwa. I-workshop ingagcina umswakama othile ngesikhathi sokuphrinta, okusiza ukubekezelela izinga lokushisa eliphezulu lokumisa.
3. BOPA
Isici esikhulu kunazo zonke ukuthi kulula ukumunca umswakama nokukhubazeka, ngakho-ke qaphela ngokukhethekile lesi sihluthulelo lapho uphrinta. Ngenxa yokuthi kulula ukumunca umswakama kanye nokukhubazeka, kufanele kusetshenziswe ngokushesha ngemva kokukhipha, futhi ifilimu esele kufanele ivalwe futhi ivikele umswakama ngokushesha. Ifilimu ye-BOPA ephrintiwe kufanele idluliselwe ngokushesha ohlelweni olulandelayo ukuze lucutshungulwe. Uma ingakwazi ukuhlanganiswa ngokushesha, kufanele ivalwe futhi ihlanganiswe, futhi isikhathi sokugcina ngokuvamile asibi ngaphezu kwamahora angu-24.
4. CPP, CPE
Kumafilimu e-PP ne-PE anganwetshiwe, ukungezwani kokuphrinta kuncane, futhi ubunzima bokuphrinta ngokweqile bukhulu kakhulu. Lapho uklama iphethini, inani le-deformation yephethini kufanele licatshangelwe ngokugcwele.
Ukwakheka kokupakishwa okuguquguqukayo
Njengoba igama liphakamisa, ukupakishwa okuguquguqukayo kwenziwa ngezingqimba ezihlukene zezinto. Kusukela endaweni yokubuka elula yezakhiwo, ukupakishwa okuguquguqukayo kungahlukaniswa kube izendlalelo ezintathu. Impahla yongqimba yangaphandle ngokuvamile i-PET, NY(PA), OPP noma iphepha, ungqimba oluphakathi nendawo i-Al, VMPT, PET noma i-NY(PA), kanti ungqimba lwangaphakathi yi-PE, CPP noma i-VMCPP. Faka i-adhesive phakathi koqweqwe lwangaphandle, ungqimba oluphakathi kanye nongqimba lwangaphakathi ukuze ubophe izingqimba ezintathu zezinto komunye nomunye.
Ekuphileni kwansuku zonke, izinto eziningi zidinga izinto ezinamathelayo ukuze zihlanganiswe, kodwa asivamile ukuqaphela ukuba khona kwalezi zinto zokunamathisela. Njengokufakwa okuguquguqukayo, izinamathiselo zisetshenziselwa ukuhlanganisa izingqimba zangaphezulu ezihlukene. Thatha ifektri ye-Garment njengesibonelo, basazi ukwakheka kokupakishwa okuguquguqukayo kanye namazinga ahlukene kangcono kakhulu. Ingaphezulu lokupakishwa okuguquguqukayo lidinga amaphethini acebile nemibala ukuze ihehe abathengi ukuthi bathenge. Phakathi nenqubo yokunyathelisa, imboni yobuciko bemibala izoqale iphrinte iphethini kungqimba lwefilimu, bese isebenzisa ingcina ukuhlanganisa ifilimu enephethini nezinye izendlalelo zangaphezulu. Glue. I-adhesive packaging adhesive (PUA) ehlinzekwa yi-Coating Precision Materials inomphumela omuhle kakhulu wokubopha kumafilimu ahlukahlukene, futhi inezinzuzo zokungathinti ikhwalithi yokuphrinta kayinki, amandla aphezulu okubopha kokuqala, ukumelana nokushisa, ukumelana nokuguga, njll.
