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 ze. Ukucaca kwezinto zokuncamathelisa kunye nokuleyibheli kubeka phambili iimfuno eziqatha.
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 i-PP, inokudibaniswa kakuhle kunye ne-PP / PE indawo yesikhongozeli, umkhuba ubonise ukuba ifilimu ye-OPP okwangoku iyona nto ingcono kakhulu yokubhalwa kwe-mold, ukutya kunye noshishino lweekhemikhali zemihla ngemihla eYurophu ibe inani elikhulu lezicelo, kwaye ngokuthe ngcembe isasazeke kwikhaya, kukho abasebenzisi abangakumbi nangakumbi baqala ukunikela ingqalelo okanye ukusebenzisa inkqubo yokuleyibhela ekwimold.
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 ibhegi 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 ngobushushu, unyango lwefilimu ye-BOPP yomphezulu we-corona inokufakwa nge-adhesive ye-resin etywinwe ubushushu, njenge-PVDC latex, i-EVA latex, njl. -extrusion laminating indlela ingasetyenziselwa ukuvelisa ifilimu yeBOPP etywinwe ubushushu. Ifilimu isetyenziswa kakhulu kwisonka, iimpahla, izihlangu kunye neekawusi zokupakisha, kunye necuba, iincwadi zigubungela ukupakishwa.
Ukuqaliswa kwefilimu ye-BOPP yamandla eenyembezi emva kokwelula kunyukile, kodwa amandla esibini okukrazula aphantsi kakhulu, ngoko ke ifilimu ye-BOPP ayinakushiywa kumacala omabini obuso benotshi, ngaphandle koko ifilimu yeBOPP kulula ukuyikrazula ekushicileleni. , 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. iifilimu 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: ukugqunywa kokutya, i-confectionery overwrap (ifilimu ejijekileyo), ukupakishwa kwamayeza (iingxowa ezifakwayo), ukubuyisela i-PVC kwiialbham zeefoto, iifolda kunye namaxwebhu, iphepha lokwenziwa, iiteyiphu ezincamathelayo, izibambi zekhadi leshishini, izibophelelo zeringi kunye nokuma. imidibaniso yesingxobo.
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.
