Ifilimu ye-OPP luhlobo lwefilimu ye-polypropylene, ebizwa ngokuba yi-co-extruded oriented oriented polypropylene (OPP) ifilimu kuba inkqubo yokuvelisa i-multi-layer extrusion. Ukuba kukho inkqubo yokwelula i-bi-directional kwi-processing, ibizwa ngokuba yi-bi-directional oriented polypropylene film (BOPP). Enye ibizwa ngokuba yi-polypropylene film (CPP) ngokuchasene nenkqubo ye-co-extrusion. Iifilimu ezintathu ziyahluka kwiipropati kunye nokusetyenziswa kwazo.
I. Usetyenziso oluphambili lwefilimu ye-OPP
I-OPP: i-polypropylene e-oriented (ifilimu), i-polypropylene ejoliswe kuyo, luhlobo olunye lwepolypropylene.
Iimveliso eziphambili ezenziwe nge-OPP:
1, iteyiphu ye-OPP: ifilimu ye-polypropylene njenge-substrate, inamandla aphezulu, ilula, ayinayo ityhefu, ingenancasa, ihambelana nokusingqongileyo, uluhlu olubanzi lokusetyenziswa kunye nezinye izibonelelo
2, iilebhile ze-OPP:kuba imakethi ihluthi kwaye ihomogenized iimveliso zemihla ngemihla, inkangeleko yiyo yonke into, umbono wokuqala umisela ukuziphatha kokuthenga komthengi. I-shampoo, ijeli yeshawa, i-detergents kunye nezinye iimveliso zisetyenziselwa kumagumbi okuhlambela afudumeleyo namanzi kunye namakhitshi, iimfuno zeleyibhile zokumelana nokufuma kwaye zingawi, kunye nokuchasana kwayo ne-extrusion kufuneka kuhambelane nebhotile, ngelixa iibhotile ezicacileyo zokubonakala kwe-adhesive kunye nezinto zokubhala zibeka phambili iimfuno ezinzima.
Iileyibhile ze-OPP ngokubhekiselele kwiilebhile zephepha, kunye nokungafihli, amandla aphezulu, umswakama, akulula ukuwa kunye nezinye iingenelo, nangona iindleko zonyuswa, kodwa zinokufumana umboniso weleyibhile omhle kakhulu kunye nokusebenzisa umphumo. Kodwa unokufumana umboniso weleyibhile olungileyo kakhulu kunye nesiphumo sokusebenzisa. Ngokuphuhliswa kobugcisa bokushicilela basekhaya, iteknoloji yokwambathisa, ukuveliswa kweeleyibhile zefilimu ezizincamathelayo kunye nokushicilela iileyibhile zefilimu akuseyiyo ingxaki, kunokuqikelelwa ukuba ukusetyenziswa kwasekhaya kweempawu ze-OPP kuya kuqhubeka nokunyuka.
Njengoko ileyibhile ngokwayo iyiPP, inokudityaniswa kakuhle nePP/PE umphezulu wesikhongozeli, ukuziqhelanisa kuye kwangqina ukuba ifilimu ye-OPP ngoku yeyona nto ilungileyo yokuleyibhela kwi-mold, ukutya kunye neshishini lemichiza yemihla ngemihla eYurophu iye yaba linani elikhulu lezicelo, kwaye ngokuthe ngcembe yasasazeka kwikhaya, kukho abasebenzisi abangakumbi nangakumbi abaqala ukuhoya okanye ukusebenzisa inkqubo yokubhala ngokubumba.
Okwesibini, injongo ephambili yefilimu yeBOPP
I-BOPP: Ifilimu ye-polypropylene ejoliswe kwi-Biaxially, kunye nolunye uhlobo lwe-polypropylene.
Iifilimu zeBOPP eziqhelekileyo ezisetyenziswayo ziquka:
● ifilimu ye-polypropylene jikelele ene-bi-oriented,
● ifilimu ye-polypropylene etywinwe ngobushushu,
● ifilimu yokupakisha icuba,
● ifilimu ye-polypropylene pearlescent ene-bi-oriented,
● ifilimu eyenziwe ngesinyithi eyenziwe nge-polypropylene,
● ifilimu ye-matte kunye nokunye.
Ukusetyenziswa okuphambili kweefilimu ezahlukeneyo zezi zilandelayo:
1, Ifilimu yeBOPP eqhelekileyo
Ikakhulu isetyenziselwa ukuprinta, ukwenza ingxowa, njengeteyiphu yokuncamathelisa kunye ne-composite kunye nezinye ii-substrates.
2, ifilimu yokutywina ubushushu beBOPP
Ikakhulu isetyenziselwa ukuprinta, ukwenza ingxowa njalo njalo.
3, ifilimu yokupakisha yesigarethi yeBOPP
Ukusetyenziswa: Isetyenziselwa ukupakisha icuba elinesantya esiphezulu.
4, ifilimu ye-BOPP eyenziwe ngeperile
Isetyenziselwa ukutya kunye nokupakishwa kwemveliso yasekhaya emva kokuprintwa.
5 、BOPP Ifilimu enesinyithi
Isetyenziswa njenge-vacuum metallization, radiation, anti-counterfeiting substrate, ukupakishwa kokutya.
6, ifilimu ye-BOPP matte
Isetyenziselwa isepha, ukutya, icuba, izithambiso, iimveliso zamayeza kunye nezinye iibhokisi zokupakisha.
7, ifilimu ye-BOPP echasene nenkungu
Isetyenziselwa ukupakishwa kwemifuno, iziqhamo, i-sushi, iintyatyambo kunye nokunye.
Ifilimu ye-BOPP yinto ebaluleke kakhulu yokupakisha izinto eziguquguqukayo, ezisetyenziswa ngokubanzi.
Ifilimu ye-BOPP ayinambala, ayinavumba, ayinancasa, ayinatyhefu, kwaye inamandla aphezulu okuxinana, amandla empembelelo, ubungqongqo, ukuqina kunye nokungafihli kakuhle.
Amandla efilimu ye-BOPP asezantsi, iglu okanye ukuprinta ngaphambi konyango lwe-corona. Nangona kunjalo, ifilimu ye-BOPP emva kokunyangwa kwe-corona, inokulungelelaniswa nokuprintwa kakuhle, inokuprintwa kombala kwaye ifumane inkangeleko entle, kwaye ke ngoko isetyenziswa ngokuqhelekileyo njengesixhobo somphezulu wefilimu.
Ifilimu ye-BOPP nayo ineziphene, ezifana nokulula ukuqokelela umbane ongatshintshiyo, akukho ukutywinwa kobushushu kunye nokunye. Kumgca wokuvelisa ngesantya esiphezulu, ifilimu ye-BOPP ixhomekeke kumbane ongatshintshiyo, kufuneka ifake isisusa sombane esingatshintshiyo.
Ukuze ufumane ifilimu ye-BOPP etywinwe ubushushu, unyango lwefilimu ye-BOPP yomphezulu we-corona inokufakwa nge-adhesive ye-resin etywinwe ubushushu, efana ne-PVDC latex, i-EVA latex, njl. Ifilimu isetyenziswa kakhulu kwisonka, iimpahla, izihlangu kunye neekawusi zokupakisha, kunye necuba, iincwadi zigubungela ukupakishwa.
Ukuqaliswa kwefilimu ye-BOPP yamandla okukrazula emva kokwelula kuye kwanda, kodwa amandla esibini okukrazula aphantsi kakhulu, ngoko ke ifilimu ye-BOPP ayinakushiywa kumacala omabini obuso bokugqibela benotshi, ngaphandle koko ifilimu ye-BOPP ilula ukuyikrazula ekushicileleni, i-laminating.
I-BOPP eqatywe ngeteyiphu yokuzincamathela inokuveliswa ukutywina iteyiphu yebhokisi, idosi ye-BOPP i-BOPP egqunywe ngokuzincamathela inokuvelisa iteyiphu yokutywina, kukusetyenziswa kweBOPP kwimarike enkulu.
Iifilimu zeBOPP zinokuveliswa ngendlela yefilimu yetyhubhu okanye indlela yefilimu ecaba. Iipropati zeefilimu ze-BOPP ezifunyenwe ngeendlela ezahlukeneyo zokucwangcisa ziyahluka. Ifilimu ye-BOPP eveliswe yindlela yefilimu ecaba ngenxa yomlinganiselo omkhulu we-tensile (ukuya kwi-8-10), ngoko ke amandla aphezulu kunendlela yefilimu yetyhubhu, ukufana kwefilimu kukwangcono.
Ukuze ufumane intsebenzo engcono kakhulu, ekusebenziseni inkqubo ngokuqhelekileyo isetyenziselwa ukuveliswa kweendlela ezininzi ze-composite.BOPP inokudibaniswa kunye nezixhobo ezahlukeneyo zokuhlangabezana neemfuno zezicelo ezizodwa. Ezifana ne-BOPP zinokudibaniswa ne-LDPE (CPP), i-PE, i-PT, i-PO, i-PVA, njl.njl. ukufumana iqondo eliphezulu lokuthintelwa kwegesi, umqobo womswakama, ukukhanya, ukuchasana nokushisa okuphezulu kunye nokuphantsi, ukumelana nokupheka kunye nokuchasana kweoli, iifilimu ezidibeneyo ezidibeneyo zingasetyenziswa ekutyeni okunamafutha.
Okwesithathu, injongo ephambili yefilimu yeCPP
I-CPP: ukucaca kakuhle, isicwebezelisi esiphezulu, ukuqina okulungileyo, umqobo wokufuma ofanelekileyo, ukumelana nobushushu obugqwesileyo, ukutywinwa lula kobushushu njalo njalo.
Ifilimu ye-CPP emva kokushicilela, ukwenza ingxowa, ifanelekile: iimpahla, i-knitwear kunye neentyatyambo zeengxowa; amaxwebhu kunye nefilimu ye-albhamu; ukupakishwa kokutya; kunye nokupakishwa komqobo kunye nefilimu yokuhombisa eyenziwe ngesinyithi.
Ukusetyenziswa okunokwenzeka kukwabandakanya: ukugqithisa kokutya, i-confectionery overwrap (ifilimu ephothiweyo), ukupakishwa kwamayeza (i-infusion bags), ukubuyisela i-PVC kwii-albhamu zeefoto, iifolda kunye namaxwebhu, iphepha lokwenziwa, iiteyiphu zokuzincamathelisa, izibambi zekhadi leshishini, izibophelelo zeringi kunye ne-stand-up pouch compotes.
I-CPP inokumelana nobushushu.
Ekubeni i-softening point ye-PP imalunga ne-140 ° C, olu hlobo lwefilimu lunokusetyenziswa kwiindawo ezifana nokuzaliswa okutshisayo, iingxowa ezitshisayo kunye ne-aseptic packaging.
Idityaniswe ne-asidi egqwesileyo, i-alkali kunye nokumelana negrisi, iyenza ibe yinto ekhethwayo kwiindawo ezifana nokupakishwa kwemveliso yesonka okanye imathiriyeli elaminethiweyo.
Ukhuseleko lokunxibelelana kokutya, ukusebenza kakuhle komboniso, akuyi kuchaphazela incasa yokutya ngaphakathi, kwaye unokukhetha amabakala ahlukeneyo eresin ukufumana iimpawu ezifunwayo.
