Ifilimu ye-OPP luhlobo lwefilimu ye-polypropylene, ebizwa ngokuba yifilimu ye-co-extruded oriented polypropylene (OPP) kuba inkqubo yemveliso yi-multi-layer extrusion. Ukuba kukho inkqubo yokwelula i-bi-directional xa kusetyenzwa, ibizwa ngokuba yi-bi-directional oriented polypropylene film (BOPP). Enye ibizwa ngokuba yi-cast polypropylene film (CPP) ngokuchaseneyo nenkqubo ye-co-extrusion. Ezi filimu zintathu zahlukile kwiimpawu zazo kunye nokusetyenziswa kwazo.
I. Iindlela eziphambili zokusetyenziswa kwefilimu ye-OPP
I-OPP: i-polypropylene ejolise ngqo (ifilimu), i-polypropylene ejolise ngqo, luhlobo olunye lwe-polypropylene.
Iimveliso eziphambili ezenziwe nge-OPP:
1, iteyiphu ye-OPP: ifilimu ye-polypropylene njengesiseko, enamandla aphezulu okutsalwa, alula, ayinatyhefu, ayinancasa, inobuhlobo nokusingqongileyo, isetyenziswa ngeendlela ezahlukeneyo kunye nezinye izibonelelo
2, iilebhile ze-OPP:kuba imakethi igcwele kwaye ifana kakhulu neemveliso zemihla ngemihla, inkangeleko yeyona nto iphambili, umbono wokuqala umisela indlela umthengi aziphatha ngayo xa ethenga. I-shampoo, i-shawa gel, iisepha kunye nezinye iimveliso zisetyenziswa kumagumbi okuhlambela afudumeleyo nafumileyo kunye neekhitshi, iimfuno zeleyibhile zokumelana nokufuma kwaye aziwi, kwaye ukumelana kwayo nokuphuma kufuneka kuhambelane nebhotile, ngelixa iibhotile ezicacileyo zokucaca kwezinto ezincamathelayo kunye neelebheli zibeka phambili iimfuno ezinzima.
Iilebhile ze-OPP xa kuthelekiswa neelebhile zephepha, ngokusobala, ngamandla aphezulu, ukufuma, akukho lula ukuwa kunye nezinye izibonelelo, nangona iindleko zonyukile, kodwa zinokufumana umboniso welebhile olungileyo kakhulu kunye nesiphumo sokusebenzisa. Kodwa zinokufumana umboniso welebhile olungileyo kakhulu kunye nesiphumo sokusebenzisa. Ngophuhliso lwetekhnoloji yokuprinta yasekhaya, itekhnoloji yokugquma, ukuveliswa kweelebhile zefilimu ezizincamathelayo kunye neelebhile zefilimu zokuprinta akusekho ngxaki, kunokuqikelelwa ukuba ukusetyenziswa kweelebhile ze-OPP ekhaya kuya kuqhubeka nokwanda.
Ekubeni ileyibhile ngokwayo iyi-PP, inokudibaniswa kakuhle nomphezulu wesikhongozeli se-PP/PE, oku kuye kwabonisa ukuba ifilimu ye-OPP okwangoku yeyona nto ilungileyo yokubhala ileyibhile, ukutya kunye noshishino lweekhemikhali zemihla ngemihla eYurophu kuye kwasetyenziswa inani elikhulu lezicelo, kwaye ngokuthe ngcembe yasasazeka kwikhaya, kukho abasebenzisi abaninzi ngakumbi abaqalayo ukunikela ingqalelo okanye ukusebenzisa inkqubo yokubhala ileyibhile kwi-mold.
Okwesibini, injongo ephambili yefilimu yeBOPP
I-BOPP: Ifilimu ye-polypropylene ejongeka kabini, ikwaluhlobo olunye lwe-polypropylene.
Iifilimu zeBOPP ezisetyenziswa rhoqo ziquka:
● ifilimu ye-polypropylene ejolise kwizinto ezimbini ngokubanzi,
● ifilimu ye-polypropylene etywinwe ngobushushu ejikeleze kabini,
● ifilimu yokupakisha icuba,
● ifilimu ye-polypropylene pearlescent ejongeka kabini,
● ifilimu yesinyithi ye-polypropylene esekwe kabini,
● ifilimu engabonakaliyo njalo njalo.
Iindlela eziphambili zokusetyenziswa kweefilimu ezahlukeneyo zezi zilandelayo:
1, ifilimu eqhelekileyo ye-BOPP
Isetyenziswa kakhulu ekuprinteni, ekwenzeni iingxowa, njengeteyiphu yokuncamathelisa kunye ne-composite kunye nezinye izinto ezisetyenziswa phantsi komhlaba.
2, ifilimu yokutywina ubushushu ye-BOPP
Isetyenziswa kakhulu ekuprinteni, ekwenzeni iibhegi njalo njalo.
Ifilimu yokupakishwa kwecuba le-BOPP 3, i-BOPP
Ukusetyenziswa: Isetyenziselwa ukupakisha icuba ngesantya esiphezulu.
4, ifilimu ye-BOPP eneperile
Isetyenziselwa ukutya kunye nokupakisha imveliso yasekhaya emva kokuprinta.
5, Ifilimu ye-BOPP Metallized
Isetyenziswa njenge-vacuum metallization, i-radiation, i-anti-counterfeiting substrate, kunye nokupakishwa kokutya.
Ifilimu ye-matte ye-6, i-BOPP
Isetyenziselwa isepha, ukutya, icuba, izinto zokuthambisa, iimveliso zamayeza kunye nezinye iibhokisi zokupakisha.
7, ifilimu yokulwa nenkungu ye-BOPP
Isetyenziselwa ukupakisha imifuno, iziqhamo, i-sushi, iintyatyambo njalo njalo.
Ifilimu yeBOPP zizinto zokupakisha eziguquguqukayo kakhulu, ezisetyenziswa kakhulu.
Ifilimu yeBOPP ayinambala, ayinavumba, ayinancasa, ayinatyhefu, kwaye inamandla aphezulu okutsalwa, amandla okutsha, ukuqina, ukuqina kunye nokubonakala kakuhle.
Amandla omphezulu wefilimu ye-BOPP aphantsi, inamathela okanye iprintiwe ngaphambi konyango lwe-corona. Nangona kunjalo, ifilimu ye-BOPP emva konyango lwe-corona, inokuguquguquka okuhle kokuprinta, inokuprintwa ngombala kwaye ifumane inkangeleko entle, kwaye ke ngoko isetyenziswa ngokuqhelekileyo njengezinto zomphezulu wefilimu edityanisiweyo.
Ifilimu ye-BOPP ikwanazo neziphene, ezifana nokuba lula ukuqokelela umbane ongashukumiyo, akukho kuvalwa kobushushu, njl. Kwimveliso ekhawulezayo, ifilimu ye-BOPP ithambekele kumbane ongashukumiyo, kufuneka kufakwe i-static equipment remover.
Ukuze kufunyanwe ifilimu ye-BOPP evalwayo ngobushushu, unyango lwe-corona yefilimu ye-BOPP yomphezulu we-corona lunokugqunywa nge-resin adhesive evalwayo ngobushushu, efana ne-PVDC latex, i-EVA latex, njl., Ingagqunywa nge-solvent adhesive, kodwa nendlela yokugquma okanye yokugquma i-co-extrusion laminating ingasetyenziselwa ukuvelisa ifilimu ye-BOPP evalwayo ngobushushu. Le filimu isetyenziswa kakhulu kwisonka, iimpahla, izihlangu kunye neekawusi zokupakisha, kunye neecuba, iincwadi zokupakisha.
Ukuqaliswa kwefilimu ye-BOPP kwamandla okukrazula emva kokuzolula kuye kwanda, kodwa amandla okwesibini okukrazula aphantsi kakhulu, ngoko ke ifilimu ye-BOPP ayinakushiywa kumacala omabini obuso bokugqibela benotshi, kungenjalo ifilimu ye-BOPP kulula ukuyikrazula ekuprinteni, ilaminating.
I-BOPP egqunywe ngeteyiphu yokuzincamathelisa inokwenziwa ukuze itywine iteyiphu yebhokisi, kwaye idosi ye-BOPP yokuzincamathelisa egqunywe yi-BOPP inokuvelisa iteyiphu yokutywina, yindlela esetyenziswa ngayo imarike enkulu.
Iifilimu zeBOPP zinokuveliswa ngendlela yefilimu yetyhubhu okanye indlela yefilimu ethe tyaba. Iimpawu zeefilimu zeBOPP ezifunyenwe ngeendlela ezahlukeneyo zokucubungula zahlukile. Ifilimu yeBOPP eveliswe ngendlela yefilimu ethe tyaba ngenxa yomlinganiselo omkhulu wokutsalwa (ukuya kuthi ga kwi-8-10), ngoko ke amandla aphezulu kunendlela yefilimu yetyhubhu, ukufana kobukhulu befilimu nako kungcono.
Ukuze kufumaneke ukusebenza ngcono ngokubanzi, indlela yokusebenzisa inkqubo idla ngokusetyenziswa ekuveliseni indlela ye-multi-layer composite. I-BOPP ingadityaniswa nezixhobo ezahlukeneyo ukuhlangabezana neemfuno zezicelo ezikhethekileyo. Ezifana ne-BOPP zingadityaniswa ne-LDPE (CPP), i-PE, i-PT, i-PO, i-PVA, njl.njl. ukuze kufumaneke inqanaba eliphezulu lomqobo wegesi, umqobo wokufuma, ukucaca, ukumelana nobushushu obuphezulu nobuphantsi, ukumelana nokupheka kunye nokumelana neoyile, iifilimu ezahlukeneyo ze-composite zingafakwa ekutyeni okunamafutha.
Okwesithathu, injongo ephambili yefilimu ye-CPP
I-CPP: ukucaca kakuhle, ukukhazimla okuphezulu, ukuqina okuhle, umqobo wokufuma olungileyo, ukumelana nobushushu okugqwesileyo, ukutywinwa okulula kobushushu njalo njalo.
Ifilimu ye-CPP emva kokuprinta, ukwenza iingxowa, ifanelekile kwiimpahla, iingxowa zempahla ezithungiweyo kunye neentyatyambo; amaxwebhu kunye nee-albhamu ifilimu; ukupakishwa kokutya; kunye nokupakishwa kwezithintelo kunye nefilimu yokuhombisa yesinyithi.
Ukusetyenziswa okunokwenzeka kukwabandakanya: ukusonga ukutya, ukusonga iilekese (ifilimu ejijekileyo), ukupakishwa kwamayeza (iingxowa zokufaka), ukutshintsha i-PVC kwii-albhamu zeefoto, iifolda kunye namaxwebhu, iphepha elenziweyo, iiteyiphu ezizincamathelisayo, izibambi zekhadi leshishini, izibopheleli zeringi kunye nee-composites zeengxowa ezimileyo.
I-CPP inokumelana kakuhle nobushushu.
Ekubeni indawo yokuthambisa yePP imalunga ne-140°C, olu hlobo lwefilimu lungasetyenziswa kwiindawo ezifana nokugcwalisa ngobushushu, iingxowa zomphunga kunye nokupakisha okungenatyhefu.
Idibene nokumelana okuhle kakhulu ne-asidi, i-alkali kunye ne-grisi, yenza ukuba ibe yinto ekhethwayo kwiindawo ezifana nokupakishwa kwemveliso yesonka okanye izinto ezifakwe i-laminate.
Ukhuseleko lwayo ekudibaneni kokutya, ukusebenza kakuhle kokuboniswa kwayo, akuyi kuyichaphazela incasa yokutya okungaphakathi, kwaye inokukhetha iintlobo ezahlukeneyo ze-resin ukuze ifumane iimpawu ezifunekayo.
