Okwangoku, umqobo ophezulu kunye neefilimu ezininzi ezisebenzayo ziphuhlisa kwinqanaba elitsha lobugcisa. Ngokuphathelele ifilimu esebenzayo, ngenxa yomsebenzi wayo okhethekileyo, inokuhlangabezana kangcono neemfuno zokupakishwa kwempahla, okanye ukuhlangabezana ngcono neemfuno zokulungelelaniswa kwempahla, ngoko umphumo ungcono kwaye ukhuphisane ngakumbi kwimarike. Apha, siza kugxila kwiifilimu ze-BOPP kunye ne-PET
I-BOPP, okanye i-Biaxially Oriented Polypropylene, yifilimu yeplastiki esetyenziswa kakhulu ekupakisheni nasekulebhelini. Ifumana inkqubo yokuqhelaniswa ne-biaxial, iphucula ukucaca kwayo, amandla, kunye nokuprintwa. Eyaziwayo ngokuguquguquka kwayo, i-BOPP isetyenziswa ngokuqhelekileyo kwipakethe eguquguqukayo, iilebhile, iiteyiphu ezincamathelayo, kunye nokusetyenziswa kwe-lamination. Inika ukubonakala kwemveliso okugqwesileyo, ukuqina, kwaye iyaphinda isetyenziswe, iyenza ibe lukhetho oludumileyo kwiimfuno ezahlukeneyo zokupakisha.
I-PET, okanye i-Polyethylene Terephthalate, i-polymer ye-thermoplastic esetyenziswa ngokubanzi eyaziwa ngokuguquguquka kwayo kunye nokucaca kwayo. Ngokuqhelekileyo isetyenziselwa ukuveliswa kweebhotile zeplastiki kwiziselo, izikhongozeli zokutya, kunye nokupakishwa, i-PET iyabonakala kwaye ineempawu ezintle zokuthintela ngokuchasene neoksijini kunye nokufuma. Ikhaphukhaphu, yomelele, kwaye inokuphinda isetyenziswe, iyenza ibe lukhetho oludumileyo kwiinkqubo ezahlukeneyo zokupakisha. Ukongeza, i-PET isetyenziswa kwiintsinga zempahla, kunye nasekwenzeni iifilimu kunye namaphepha ngeenjongo ezahlukeneyo.
Umahluko
I-PET imele i-polyethylene terephthalate, ngelixa i-BOPP imele i-biaxially oriented polypropylene. Iifilimu ze-PET kunye ne-BOPP ziifilimu ezicekethekileyo zeplastiki ezidla ngokusetyenziselwa ukupakisha. Zombini ukhetho oludumileyo lokupakishwa kokutya kunye nezinye izicelo, ezinje ngeeleyibhile zemveliso kunye nokusonga okukhuselekileyo.
Ngokumalunga nomahluko phakathi kweefilimu ze-PET kunye ne-BOPP, owona mahluko ucacileyo ziindleko. Ifilimu ye-PET ithande ukubiza kakhulu kunefilimu yeBOPP ngenxa yamandla ayo aphezulu kunye neempawu zokuthintela. Ngelixa ifilimu ye-BOPP inexabiso elithe kratya, ayinikezeli ngokhuseleko olufanayo okanye iipropathi zomqobo njengefilimu ye-PET.
Ukongeza kwiindleko, kukho ukungafani kokumelana nokushisa phakathi kweentlobo ezimbini zefilimu. Ifilimu ye-PET inendawo yokunyibilika ephezulu kunefilimu ye-BOPP, ngoko inokumelana namaqondo obushushu aphezulu ngaphandle kokujija okanye ukucutheka. Ifilimu ye-BOPP ixhathisa ngakumbi kumswakama, ngoko inokukhusela iimveliso ezithintekayo kumswakama.
Ngokuphathelele kwiipropathi ze-optical ze-PET kunye ne-BOPP films, ifilimu ye-PET inokucaca okuphezulu kunye negloss, ngelixa ifilimu ye-BOPP ine-matte finish. Ifilimu yePET lolona khetho lungcono ukuba ujonge ifilimu ebonelela ngeempawu ezibalaseleyo zamehlo.
Iifilimu zePET kunye neBOPP zenziwe ngeentlaka zeplastiki kodwa ziqulethe izinto ezahlukeneyo. I-PET iquka i-polyethylene terephthalate, idibanisa i-monomers ezimbini, i-ethylene glycol, kunye ne-terephthalic acid. Le ndibaniselwano yenza into eyomeleleyo kunye nekhaphukhaphu imelana kakhulu nobushushu, iikhemikhali, kunye nezinyibilikisi. Ngakolunye uhlangothi, ifilimu ye-BOPP yenziwe nge-polypropylene e-biaxially-oriented, indibaniselwano yepolypropylene kunye nezinye izinto zokwenziwa. Esi sixhobo sinamandla kwaye sikhaphukhaphu kodwa sinokumelana nobushushu kunye neekhemikhali.
Ezi zinto zimbini zinezinto ezininzi ezifanayo ngokubhekiselele kwiimpawu ezibonakalayo. Zombini zicace kakhulu kwaye zicace kakhulu, zizenza zilungele usetyenziso olufuna umbono ocacileyo wemixholo. Ukongeza, zombini izixhobo ziqinile kwaye zibhetyebhetye, zizenza zilungele izicelo ezahlukeneyo.
Nangona kunjalo, kukho iiyantlukwano eziphambili. I-PET iqinile ngakumbi kunefilimu ye-BOPP kwaye ayichaphazeli kakhulu ukukrazulwa okanye ukugqobhoza. I-PET inendawo ephezulu yokunyibilika kwaye iyakwazi ukumelana nemitha ye-UV. Kwelinye icala, ifilimu yeBOPP ithambile ngakumbi kwaye inokolulwa kwaye ibunjwe ukuze ilingane izicelo ezahlukeneyo.
isishwankathelo
Ukuqukumbela, ifilimu yezilwanyana kunye nefilimu yeBopp inomahluko wabo. Ifilimu ye-PET yifilimu ye-polyethylene terephthalate, eyenza i-thermoplastic enokuthi ifudumale kwaye ibunjwe ngaphandle kokulahlekelwa ingqibelelo yesakhiwo. Inozinzo oluhle kakhulu lwe-dimensional, iipropathi zamehlo, kunye nokumelana neekhemikhali, kuyenza ibe lukhetho olukhulu kwizicelo ezininzi. Ifilimu ye-Bopp, kwelinye icala, yifilimu ye-polypropylene ejoliswe kwi-biaxially. Yimathiriyeli ekhaphukhaphu kodwa eyomeleleyo eneempawu ezibalaseleyo zokubona, oomatshini, kunye ne-thermal. Kuyinzuzo kwizicelo apho ukucaca okuphezulu kunye namandla aphezulu kufuneka.
Xa ukhetha phakathi kwezi filimu zimbini, kubalulekile ukuqwalasela isicelo. Ifilimu ye-PET ifanelekile kwizicelo ezifuna ukuzinza okukhulu kwe-dimensional kunye nokumelana nemichiza. Ifilimu yeBopp ifaneleke ngakumbi kwizicelo ezifuna ukucaca okuphezulu kunye namandla aphezulu.
Siyathemba ukuba le bhlog ikuncede ukuba uqonde ngcono umahluko phakathi kwefilimu yezilwanyana zasekhaya kunye ne-Bopp kwaye ukhethe eyona ifanele isicelo sakho.
