Njengoko ilizwe liya lisiba ngqongqo ngakumbiulawulo lokhuseleko lokusingqongileyo, Ukusukela abathengi bokugqibela ukugqibelela, impembelelo ebonakalayo kunyeokusingqongileyo okuluhlazaukukhuselwa kokupakishwa kwemveliso yeebrendi ezahlukeneyo kuye kwabangela ukuba abanini-brand abaninzi bongeze into yephepha kuyilo lokupakisha.Ukuquka umhleli ngokwakhe, ndithanda ukupakishwa kwephepha kakhulu, kwaye ndihlala ndiqokelela iingxowa zokupakisha zolu hlobo.Iimveliso ezigqityiweyo zenkampani yethu nazo ziyamangalisa kakhulu, njengeikofu kraft iphepha uziphu bag kunye ivelufa umoyaesisanda kuyenza mva nje.
Uyilo lwepakethe yeplastiki ehlanganisiweyo iyinoveli kwaye iyodwa, nto leyo izise iziphumo zokusebenza ezingaqhelekanga kubanini beempawu.Nangona kunjalo, kwinkqubo yokuvelisa, iinkqubo ezidibeneyo ezisetyenzisiweyo ziquka i-composite eyomileyo, i-extrusion composite, i-solvent-free composite, njl. Iingxaki ezifana nokutywinwa kobushushu kunye namadyungudyungu.Ukuphucula umgangatho wokupakishwa kwe-paper-plastic composite, kuyimfuneko ukuqala ngenkqubo ngesiseko sokuqonda okunzulu kolu hlobo lokupakisha, ukuze kufezekiswe kabini umphumo ngesiqingatha somzamo.
1. Imeko yangoku yokupakishwa kwe-paper-plastiki composite
Ngokumalunga nolwakhiwo, kukho iindlela ezahlukeneyo zemveliso yephepha-plastiki yesakhiwo kwimarike, eyahlulahlulwe ngokubanzi kwi-OPP//PAP, PET//PAP, PAP//CPP(PE), PAP//AL, njl. iphepha: uphawu ngalunye lukhetha iintlobo ezahlukeneyo zephepha, ubukhulu kunye nobunzima bephepha bohlukile, ukusuka kwi-20 ukuya kwi-100g.Inkqubo yemveliso ibandakanyai-extrusion compounding, i-compounding eyomileyo, i-solvent-free compounding, njl.
Ngolu thelekiso lungentla, inkqubo nganye ineengenelo nezingeloncedo.Ngamagama alula, i-solvent-free composites ineenzuzo ekusebenzeni okubanzi, njengobuchule, ilahleko, njl. Ukuba ubungakanani bomyalelo buncinci kwaye umyalelo unzima, sisancoma ukudibanisa okomileyo (nikela ingqalelo ekukhethweni kwephepha, iglue. njl.).
2. Ukukhethwa kwezinto
Zininzi iintlobo zemathiriyeli yephepha ezinokusetyenziselwa izinto ezidityanisiweyo zeplastiki, kubandakanywa iphepha eligqunyiweyo, iphepha elimhlophe lekraft, iphepha lekraft elimthubi, iphepha elincamathelayo kabini, iphepha lokubhala, iphepha eligqunywe ukukhanya, iphepha leperile, iphepha elithambileyo. iphepha elisisiseko, njl. njl., kwaye ngokweemfuno zokuyila ukupakisha, zingenziwa zibe yizakhiwo zezinto ezidibeneyo ezidibeneyo, ezifana ne-OPP/iphepha, i-PET/iphepha, i-CPP//iphepha, i-PE//iphepha, i-AL//iphepha, njl.
Kukho malunga neninzi yokuhlelwa ngokweendlela ezahlukeneyo zokusetyenziswa, iinkqubo, njl., eziqhele ukusetyenziswa kwibala lokupakisha oluguquguqukayo liphepha le-kraft, iphepha elimhlophe le-kraft, iphepha elithambileyo lomqhaphu, iphepha lesiseko, iphepha leperile, njl., uluhlu lobungakanani ukusuka kwi-25gsm. ukuba 80gsm.Ngenxa yobuninzi bephepha kunye nokusetyenziswa okwahlukileyo, la manqaku alandelayo kufuneka athathelwe ingqalelo xa usebenzisa iphepha elahlukileyo:
① - Ngokuqhelekileyo, icala eligudileyo lephepha lilula ukuxhamla kunye nefilimu, ngelixa i-rough side kunye nefilimu kunzima ukudibanisa.Oku kubangelwa ikakhulu kwimingxuma kunye nemigodi kwicala elirhabaxa.I-Adhesive igcwalisa imingxuma.
②Nika ingqalelo kuxinaniso lwephepha.Iintsinga zamanye amaphepha zikhululekile kakhulu.Nangona iphepha kunye nefilimu ziboshwe kakuhle xa zilayitiwe, ziyakwazi ukuchithwa emva kokutywinwa kobushushu.
③ Isiqulatho sokufuma sephepha sikwanalo nefuthe elithile kwisiphumo seqhina.Ngokwamava obuqu, isiqulatho sokufuma ephepheni akufuneki sidlule ngokubanzi kwi-0.4%.Ingcinga elungileyo ukushiya iphepha ehovini kangangeentsuku ezi-1 ukuya kwezi-2 phambi kokuveliswa
④ Nika ingqalelo ukucoceka komphezulu wephepha.
3. Uyilo lwesakhiwo
Xa uqulunqa isakhiwo sesitya sokupakisha sephepha-plastiki, kuyimfuneko ukuqonda iimpawu zokupakisha kwaye ukhethe izinto ezifanelekileyo kunye nesakhiwo.
Ngokubhekiselele kwisakhiwo sengxowa, isetyenziselwa kakhulu ukupakisha izinto eziqinileyo, kwaye imilo ithambile.Ukuqwalasela umsebenzi wokupakisha kunye neemfuno zokubonisa imveliso, isakhiwo sinokuhlulwa sibe ziintlobo ezintathu: akukho hlobo lwefestile, uhlobo lwefestile ye-strip kunye nefestile ekhethekileyo.
Isikhwama esingenafestile sisona sakhiwo siqhelekileyo sohlobo lwengxowa.Umzimba oyintloko yimpahla yephepha (njengephepha le-kraft), kwaye iileyile zangaphakathi nangaphandle zihlala zikhuselwe iifilimu zeplastiki ezifana ne-PE (i-polyethylene) kunye ne-PP (i-polypropylene), enokuthintela ngokufanelekileyo umswakama kunye ne-oksijini ukukhusela umxholo. , kunye nenkqubo yokubumba ngokusisiseko iyafana naleyo yokupakishwa kweplastiki eguquguqukayo.Okokuqala, iphepha lidibaniswe nefilimu yeplastiki kwaye emva koko ifakwe ubushushu ukwenza iingxowa;
Isikhwama sefestile ye-strip kunye nefestile enemilo ekhethekileyo yohlobo lwengxowa yesakhiwo sefestile, kwaye iphepha lisetyenziselwa ukwenza imingxuma yomoya, ukwenzela ukuba ukupakishwa kubonise izitayela ezahlukeneyo.Ukongeza kokugcina ukungafihli kwengxowa yokupakisha, inokuba nayo ukuthungwa kwephepha.Indlela yokwenza isikhwama sefestile kukudibanisa ifilimu yeplastiki enobubanzi obuncinci kunye namaphepha amabini kunye nenye ifilimu yeplastiki ebanzi.Kukho iindlela ezimbini zokwenza iifestile ezinemilo ekhethekileyo.Enye kukuvula ifestile kwizinto zephepha kwangaphambili ukwenza iimilo ezahlukeneyo, kwaye emva koko udibanise izinto.Izinto eziphathekayo zoluhlu oludibeneyo nazo zingatshintshwa kwaye ziyilwe kwindawo enkulu ukuphucula ukuguquguquka kwenkqubo yokuvelisa.
4. Inkqubo yokuvelisa
Inkqubo yokudibanisa okomileyo sele ikhulile.Amashishini akhetha iglue esekelwe kwi-solvent-based-component glue, kwaye akhethe iglue yecandelo elinye kunye neglue esekelwe emanzini.Apha sicebisa ukuba kungakhathaliseki ukuba yiyiphi iglue esetyenziswayo, ezi ngongoma zilandelayo kufuneka ziqwalaselwe:
a.Ukukhethwa kwephepha kubaluleke kakhulu;
b.Ulawulo lwesiqulatho samanzi ephepheni;
c, iphepha elikhazimlayo kunye nokukhethwa kwe-matte;
d.Nika ingqalelo ukucoceka kwephepha;
e, ukulawulwa kobuninzi beglue;
f.Ukulawulwa kwesantya ukuthintela intsalela ye-solvent ukuba ibe phezulu kakhulu.
