Iimpawu ezisebenzayo zokupakisha izinto zefilimu ziqhuba ngokuthe ngqo uphuhliso olusebenzayo lwezinto ezidibeneyo zokupakisha eziguquguqukayo. Oku kulandelayo sisingeniso esifutshane kwiimpawu ezisebenzayo zezinto ezininzi zokupakisha ezisetyenziswa ngokuqhelekileyo.
1. Izinto zokupakisha ezisetyenziswa ngokuqhelekileyo: Ifilimu ye-PE
Izinto ze-PE ezivaliweyo ngobushushu ziye zavela kwiifilimu ezivuthelweyo zomgangatho omnye ukuya kwiifilimu ezininzi ezidityanisiweyo, ukwenzela ukuba iifomyula zemigangatho yangaphakathi, ephakathi nangaphandle inokuyilwa ngokwahlukileyo. Uyilo lwefomula yokudibanisa yeentlobo ezahlukeneyo zeentlaka zepolyethylene zinokuvelisa amaqondo obushushu okutywina ahlukeneyo, amanqanaba obushushu obutywiniweyo ahlukeneyo, iipropathi ezahlukeneyo zokuchasana nokutywinwa,hamandla okunamathela, iziphumo ezichasene ne-static, njl., ukuhlangabezana neemfuno zokupakisha imveliso ethile kunye nezixhobo zefilimu ze-PE ezineempawu ezahlukeneyo zokusebenza.
Kwiminyaka yakutshanje, iifilimu ze-biaxially oriented polyethylene (BOPE) nazo ziye zaphuhliswa, eziphucula amandla okuqina kweefilimu ze-polyethylene kwaye zibe namandla aphezulu okutywinwa kobushushu.
2. Izinto zeFilimu zeCPP
Izinto ze-CPP zisetyenziswa ngokuqhelekileyo kwi-BOPP / CPP esi sakhiwo sokupakisha ukukhanya kobumanzi, kodwa i-resin ye-resin ye-CPP eyahlukeneyo inokwenziwa ngeendlela ezahlukeneyo zokusebenza zefilimu, ezifana nokuphucula ukumelana nobushushu obuphantsi, ukuchasana nokupheka kobushushu obuphezulu, ukuhla. iqondo lobushushu lokutywina, amandla aphezulu okugqobhoza, ukuxhathisa ukubola, kunye nezinye iimpawu ezisebenzayo zezixhobo zokutywina ubushushu.
Rkwiminyaka yamuva, ishishini liye laphuhlisa ifilimu ye-matte ye-CPP, inyusa impembelelo ebonakalayo yeengxowa zefilimu ze-CPP.
3. Izinto zefilimu zeBOPP
Ifilimu ehlanganisiweyo yokupakisha ukukhanya yeyona isetyenziswa ngokuqhelekileyo yifilimu yokukhanya yeBOPP kunye nefilimu ye-BOPP matte, kukwakho nefilimu yokutywina ubushushu beBOPP (icala elinye okanye icala eliphindwe kabini lokutywinwa kobushushu), ifilimu yeperile yeBOPP.
I-BOPP ibonakaliswe ngamandla aphakamileyo obunzima (ilungele ukuprintwa kwemibala emininzi), iipropathi ezigqwesileyo zokuthintela umphunga wamanzi, ezisetyenziswa kakhulu ekupakishweni kokukhanya okuchasene nokufuma kobuso bezinto eziprintiweyo.
Ifilimu ye-BOPP ye-matte enempembelelo yokuhlobisa i-matte efana nephepha. Ifilimu yokutywina ubushushu be-BOPP inokusetyenziswa njengesixhobo sokupakisha esinomgangatho omnye, njengokusonga ukupakishwa kwangaphakathi kweelekese nge. Ifilimu ye-pearl ye-BOPP isetyenziselwa kakhulu ukupakisha i-ice-cream kwizixhobo zokutywina ubushushu, inokugcina ushicilelo lwe-inki emhlophe, ubuninzi bayo obuphantsi, i-2 ukuya kwi-3N / 15mm yokutywina amandla ukuze ibhegi ivuleke ngokulula ukukhupha imixholo.
Ukongeza, njengefilimu ye-BOPP echasene nenkungu, ifilimu ye-holographic OPP laser, iphepha le-PP lokwenziwa, ifilimu ye-BOPP ye-biodegradable kunye nolunye uchungechunge lweefilimu ezisebenzayo ziye zathandwa kwaye zasetyenziswa kuluhlu oluthile.
4. Izinto zokupakisha ezisetyenziswa ngokuqhelekileyo: Izinto zefilimu yePET
Ifilimu yokukhanya eqhelekileyo ye-12MICRONS PET isetyenziswa ngokubanzi kwipakethe eguquguqukayo ehlanganisiweyo, amandla omatshini emveliso yawo yokupakisha ene-laminated iphezulu kakhulu kuneemveliso ezihlanganisiweyo ze-BOPP zomaleko ophindwe kabini (kancinci ngaphantsi kwe-BOPA yeemveliso ezidibeneyo eziphindwe kabini), kunye nomthamo wesithintelo se-oxygen. ye-BOPP / PE (CPP) ifilimu edibeneyo yokunciphisa i-20 kumaxesha e-30.
Ukumelana nobushushu bezinto ze-PET zilungile kakhulu, kwaye zingenziwa kwi-flatness yeengxowa ezilungileyo. ifilimu ye-PET enobushushu obutshisayo, ifilimu ye-matte ye-PET PET eshushu, ifilimu ye-matte ye-PET, ifilimu ye-polyester ephezulu, ifilimu ye-PET twist, ifilimu ye-PET yokukrazula kunye nezinye iimveliso ezisebenzayo nazo ziyasetyenziswa.
5. Izinto eziqhelekileyo zokupakisha : ifilimu yenylon
Ifilimu yenayiloni ejolise kwi-Biaxially isetyenziswa ngokubanzi kwi-vacuum, iingxowa ezibilayo kunye neziqhumayo ngokomelela kwayo okuphezulu, ukuxhathisa kokugqobhoza okuphezulu, ukumelana nobushushu obuphezulu kunye nomqobo ongcono weoksijini.
Uninzi lweepowutshi ezilaminethiweyo ezinomthamo omkhulu ngaphezulu kwe-1.7kg nazo zisebenzisa iBOPA//isakhiwo se-PE ukuxhathisa okulungileyo kokulahla.
Ifilimu enayiloni ephosiweyo, esetyenziswa kakhulu eJapan ukupakisha ukutya okunomkhenkce, enokumelana nobushushu obuphantsi, inciphisa isantya sokuqhekeka kwengxowa ngexesha lokugcinwa kobushushu obuphantsi kunye nokuhamba.
6. Izinto eziqhelekileyo zokuPakisha : I-Aluminiyam yokugquma iFilimu yeMetalized
I-aluminizing ye-vacuum ikwifilimu (efana ne-PET, i-BOPP, i-CPP, i-PE, i-PVC, njl. njl.) umgangatho wokwakheka komgca we-aluminium exineneyo, ngaloo ndlela ukwandisa kakhulu ifilimu kumphunga wamanzi, i-oksijini, amandla okuthintela ukukhanya. , eyona nto isetyenziswa kakhulu kwi-composite flexible packaging VMPET, izinto ze-VMCPP.
I-VMPET ye-laminating ye-three-layer, i-VMCPP ye-laminating ye-two-layer.
I-OPP // VMPET // Isakhiwo se-PE ngoku sele sisetyenziswe ngokuvuthiweyo kwimifuno yokushicilela, ihluma iimveliso kwi-vacuum yokubilisa ukupakisha. Ulwakhiwo lwe-PE ngoku luye lwasetyenziswa ngokuqolileyo ukukhama imifuno, ihluma iimveliso kwi-vacuum ebilayo yokupakisha, ukuze soyise iintsilelo zeemveliso eziqhelekileyo ze-aluminium, i-aluminium layers kulula ukufuduka, musa ukumelana neentsilelo zokubilisa, ukuphuhliswa kweemveliso ze-VMPET kunye uhlobo lokugquma ezantsi, phambi nasemva abilayo amandla echuliweyo ngaphezu 1.5N / 15mm, kwaye umaleko aluminiyam ayibonakali ukufuduka, ukuphucula ukusebenza umqobo jikelele ingxowa.
7. Izinto eziqhelekileyo zokupakisha: I-aluminium foil
Ifoyile yeAluminiyam yokupakishwa okuguquguqukayo ngokuqhelekileyo yi-6.5μm okanye 9μUbukhulu be-m 12microns, ifoyile ye-aluminiyam ngokwethiyori sisithintelo esiphakamileyo sezinto, ukungenwa kwamanzi, ukungenwa kweoksijini, ukukhanya kungene "0", kodwa eneneni kukho imingxunya kwifoyile yealuminiyam kunye nokusonga ukunganyangeki kwepinhole, kukho inani loqobo lokupakishwa komqobo. isiphumo asifanelekanga. Isitshixo ekusetyenzisweni kwe-aluminium foil kukuphepha i-pinholes ngexesha lokucubungula, ukupakishwa kunye nokuthutha, ngaloo ndlela ukunciphisa umthamo wangempela womqobo. Kwiminyaka yakutshanje, kukho umkhwa wokuba izinto zefoyile ye-aluminiyam zitshintshwe ngempahla yokupakisha eyongayo kwiindawo zabo zesicelo zemveli.
8. Izinto zokupakisha ezisetyenziswa ngokuqhelekileyo: iifilimu ezifakwe kwi-high-barrier films
Ikakhulu ifilimu egqunywe nge-PVDC (ifilimu yokugquma i-K), ifilimu egqunywe nge-PVA (Ifilimu yokwambathisa).
I-PVDC inomqobo ogqwesileyo weoksijini kunye nokumelana nokufuma, kwaye inokukhanya okugqwesileyo, ifilimu ye-PVDC egqunyiweyo esetyenziswa kwifilimu yesiseko ikakhulu yiBOPP, BOPET, BOPA, CPP, njl., kodwa inokuba yiPE, PVC, cellophane kunye nezinye iifilimu. ukupakishwa okuhlanganisiweyo okuguquguqukayo kweyona isetyenziswa kakhulu i-KOPP, i-KPET, ifilimu ye-KPA.
9. Izinto eziqhelekileyo zokuPakisha: I-Co-extruded High Barrier Films
I-Co-extrusion iplastiki ezimbini okanye ngaphezulu ezahlukeneyo, ngokusebenzisa ezimbini okanye ngaphezulu kwe-extruders ezimbini, ngokulandelanayo, ukwenzela ukuba iindidi zeplastiki ezinyibilikayo kunye neplastiki yentloko yokufa, ukulungiswa kweefilimu ezidibeneyo zendlela yokubumba. Iifilimu ezidityanisiweyo ezidityanisiweyo zesithintelo zihlala zenziwe ngokudityaniswa kweeplastiki zesithintelo, iiplastiki ze-polyolefin kunye neentyantyambo ezincamathelayo zeentlobo ezintathu zemathiriyeli, iiresin zesithintelo ikakhulu ziyi-PA, EVOH, PVDC, njl.
Oku ngasentla zizinto eziqhelekileyo zokupakisha kuphela, eqinisweni, ubuncinane ukusetyenziswa kwe-oxide ye-oxide yokugcoba, i-PVC, i-PS, i-PEN, iphepha, njl. iipropati ezisebenzayo zezinto zefilimu. Ukunyibilika kweefilimu ezahlukeneyo ezisebenzayo, ngokunyibilikisa okomileyo, ukunyibilikisa okunganyibilikiyo, i-extrusion lamination kunye nobunye ubuchwephesha obuhlanganisiweyo ukuvelisa izixhobo zokupakisha ezisebenzayo eziguquguqukayo ukuhlangabezana neemfuno ezahlukeneyo.iimvelisoukupakishwa.
