Isishwankathelo somsebenzi onxulumene nezixhobo zokupakisha ezisetyenziswa rhoqo kushishino lokupakisha oluguquguqukayo!

Iimpawu zokusebenza kwezixhobo zefilimu zokupakisha ziqhuba ngokuthe ngqo uphuhliso olusebenzayo lwezixhobo zokupakisha ezidityanisiweyo neziguquguqukayo. Oku kulandelayo yintshayelelo emfutshane kwiimpawu zokusebenza kwezixhobo zokupakisha ezininzi ezisetyenziswa rhoqo.

1. Izinto zokupakisha ezisetyenziswa rhoqo: ifilimu ye-PE 

Izixhobo ze-PE ezivalwayo ngobushushu ziye zavela kwiifilimu ezivuthelweyo zomaleko omnye ukuya kwiifilimu ezivalwayo zomaleko omninzi, ukuze iifomyula zomaleko wangaphakathi, ophakathi nowangaphandle zinokuyilwa ngokwahlukileyo. Uyilo lwefomyula yokuxuba yeentlobo ezahlukeneyo zeeresini ze-polyethylene lunokuvelisa amaqondo obushushu ahlukeneyo okuvalwa, uluhlu lobushushu oluhlukeneyo lokuvalwa ngobushushu, iipropati ezahlukeneyo zokungcolisa ezichasene nokuvalwa,hamandla okuncamathelisa, iziphumo ezichasene nokuma, njl.njl., ukuhlangabezana neemfuno ezithile zokupakisha imveliso kunye nezixhobo zefilimu ze-PE ezineempawu ezahlukeneyo zokusebenza.

Kwiminyaka yakutshanje, kuye kwaveliswa iifilimu ze-polyethylene (BOPE) ezijolise kwicala elinye, eziphucula amandla okuxinana kweefilimu ze-polyethylene kwaye zinamandla aphezulu okuvala ubushushu.

2.  Izixhobo zeFilimu yeCPP 

Izixhobo ze-CPP zisetyenziswa kakhulu kwi-BOPP/CPP kule ndlela yokupakisha ukukhanya engangeni kumswakama, kodwa iindlela ezahlukeneyo ze-resin ze-CPP zinokwenziwa ngeepropati ezahlukeneyo zokusebenza kwefilimu, ezinje ngokumelana nobushushu obuphantsi, ukumelana nokupheka kubushushu obuphezulu, ubushushu obuphantsi bokuvala, amandla aphezulu okubhoboza, ukumelana nokugqwala, kunye nezinye iimpawu zokusebenza kwezinto zokuvala ubushushu.

RKwiminyaka yakutshanje, eli shishini likwaphuhlise ifilimu ye-CPP matte, nto leyo eyandisa isiphumo sokubonisa okubonakalayo kweengxowa zefilimu ze-CPP ezineleya enye.

 3. Izixhobo zefilimu zeBOPP

Ifilimu edibeneyo yokupakisha ukukhanya isetyenziswa kakhulu yifilimu eqhelekileyo yokukhanya yeBOPP kunye nefilimu ye-BOPP matte, kukwakho nefilimu yokuvala ubushushu yeBOPP (ukuvala ubushushu obunecala elinye okanye obunecala elinye), ifilimu yepearl yeBOPP.

I-BOPP ibonakaliswa ngamandla aphezulu okuxinana (ifanelekile kwi-multi-color overprinting), iipropati ezintle zokuthintela umphunga wamanzi, ezisetyenziswa kakhulu ekupakisheni ukukhanya okunganyangekiyo komswakama kumphezulu wezinto eziprintiweyo.

Ifilimu ye-BOPP matte enesiphumo sokuhombisa esingamatte esifana nephepha. Ifilimu yokutywina ubushushu ye-BOPP ingasetyenziswa njengezixhobo zokupakisha ezimaleko omnye, njengokusonga iphakheji yangaphakathi yeelekese ngayo. Ifilimu ye-BOPP pearl isetyenziswa kakhulu kwizixhobo zokutywina ubushushu zokupakisha i-ayisikhrim, inokonga ukuprintwa kwe-inki emhlophe, incinci, amandla okutywina ayi-2 ukuya kwi-3N/15mm ukuze kube lula ukuyivula ingxowa ukuze ikhuphe umxholo.

Ukongeza, ezifana nefilimu ye-BOPP yokulwa nenkungu, ifilimu ye-holographic OPP laser, iphepha le-PP synthetic, ifilimu ye-BOPP ebolayo kunye nezinye iifilimu ezisebenzayo ze-BOPP nazo ziye zathandwa kwaye zasetyenziswa kuluhlu oluthile.

 4. Izinto zokupakisha ezisetyenziswa rhoqo: Izinto zefilimu yePET

Ifilimu yokukhanya ye-12MICRONS PET eqhelekileyo isetyenziswa kakhulu ekupakisheni okuguquguqukayo okudityanisiweyo, amandla oomatshini eemveliso zayo zokupakisha ezilaminethiweyo aphezulu kakhulu kuneemveliso ze-BOPP ezidityanisiweyo ezimaleko amabini (ezingaphantsi kancinci kuneemveliso ze-BOPA ezidityanisiweyo ezimaleko amabini), kunye nomthamo womqobo weoksijini wefilimu ye-BOPP/PE (CPP) ukunciphisa amaxesha angama-20 ukuya kuma-30.

Ukumelana nobushushu kwezinto zePET kulungile kakhulu, kwaye kungenziwa kube lula kwiingxowa ezilungileyo. Ifilimu encitshiswa bubushushu yePET, ifilimu encitshiswa bubushushu yePET PET, ifilimu encitshiswa bubushushu yePET, ifilimu encitshiswa bubushushu yePET, ifilimu encitshiswa bubushushu yePET, ifilimu encitshiswa bubushushu yePET kunye nezinye iimveliso ezisebenzayo nazo ziyasetyenziswa.

 5. Izinto zokupakisha eziqhelekileyo: ifilimu ye-nylon

Ifilimu yenylon ejongeka kabini isetyenziswa kakhulu kwiingxowa ze-vacuum, zokubilisa nezokukhupha umphunga ngenxa yamandla ayo aphezulu, ukumelana nokubhoboza okuphezulu, ukumelana nobushushu obuphezulu kunye nomqobo ongcono we-oxygen.

Uninzi lweengxowa ezinkulu ezine-laminate ezingaphezulu kwe-1.7kg zisebenzisa nesakhiwo se-BOPA//PE ukuze zikwazi ukumelana nokuwa kakuhle.

Ifilimu ye-nylon eyenziwe nge-cast, esetyenziswa kakhulu eJapan ekupakisheni ukutya okukhenkcezisiweyo, enokumelana okuhle nobushushu obuphantsi, nto leyo enciphisa izinga lokuqhekeka kwengxowa ngexesha lokugcina nokuthutha ubushushu obuphantsi.

 6. Izinto zokuPakisha eziqhelekileyo: Ifilimu yesinyithi egqunywe nge-aluminium

Ukucoca nge-vacuum kwifilimu (ezifana ne-PET, i-BOPP, i-CPP, i-PE, i-PVC, njl.njl.) umphezulu wokwenziwa komaleko we-aluminium exineneyo, ngaloo ndlela kwandisa kakhulu ifilimu kumphunga wamanzi, ioksijini, umthamo womqobo wokukhanya, osetyenziswa kakhulu kwi-composite flexible packaging VMPET, izixhobo ze-VMCPP.

I-VMPET yokubopha ilaminati enezintlu ezintathu, i-VMCPP yokubopha ilaminati enezintlu ezimbini.

Isakhiwo se-OPP//VMPET//PE ngoku sisetyenziswe ngokuvuthwa kwimifuno ecinezelweyo, iimveliso zesprouts kwiphakheji yokubilisa ye-vacuum. Isakhiwo se-PE ngoku sisetyenziswe ngokuvuthwa ukucinezela imifuno, iimveliso zesprouts kwiphakheji yokubilisa ye-vacuum, ukuze koyiswe iintsilelo zeemveliso eziqhelekileyo ze-aluminium, kulula ukufuduka komaleko we-aluminiyam, musa ukumelana neentsilelo zokubilisa, uphuhliso lweemveliso ze-VMPET ezinohlobo lokugquma olusezantsi, ngaphambi nasemva kokubila kwamandla okuxobuka angaphezu kwe-1.5N/15mm, kwaye umaleko we-aluminiyam awubonakali ufuduka, ukuphucula ukusebenza komqobo ngokubanzi kwengxowa.

7. Izinto zokupakisha eziqhelekileyo: Ifoyile ye-aluminium

Ifoyile ye-aluminium yokupakisha okuguquguqukayo ngokubanzi yi-6.5μm okanye 9μUbukhulu be-m 12microns, i-aluminium foil ngokwethiyori iyinto ethintela amanzi, i-oxygen permeability, i-light permeability yi-"0", kodwa eneneni kukho imingxuma kwi-aluminium foil kunye nokugoba okungalunganga kwemingxuma yemingxuma, kukho inani lemiphumo yokupakisha imingxuma engafanelekanga. Isitshixo sokusetyenziswa kwe-aluminium foil kukuphepha imingxuma yemingxuma ngexesha lokucubungula, ukupakisha kunye nokuthuthwa, ngaloo ndlela kunciphisa amandla okuthintela okwenyani. Kwiminyaka yakutshanje, kukho umkhwa wokuba izinto ze-aluminium foil zithathelwe indawo zizinto zokupakisha ezingabizi kakhulu kwiindawo zazo zesiqhelo zokusetyenziswa.

8. Izixhobo zokupakisha ezisetyenziswa rhoqo: iifilimu ezigqunywe ngomqobo ophezulu

Ikakhulu ifilimu egqunywe yiPVDC (ifilimu egqunywe yiK), ifilimu egqunywe yiPVA (ifilimu egqunywe yiA).

I-PVDC inomqobo ogqwesileyo we-oksijini kunye nokumelana nokufuma, kwaye inombala ocacileyo, ifilimu yePVDC egqunywe nge-coated esetyenziswa kwifilimu esisiseko ikakhulu yi-BOPP, BOPET, BOPA, CPP, njl.njl., kodwa ikwanokuba yi-PE, PVC, i-cellophane kunye nezinye iifilimu, kwiphakheji eguquguqukayo edibeneyo kwifilimu ye-KOPP, KPET, KPA esetyenziswa kakhulu.

9. Izixhobo zokuPakisha eziqhelekileyo: Iifilimu eziBamba iiNqanaba eziPhakamileyo eziDityanisiweyo

I-Co-extrusion ziiplastiki ezimbini okanye ngaphezulu ezahlukeneyo, ngokusebenzisa ii-extruders ezimbini okanye ngaphezulu, ngokulandelelana, ukuze iintlobo ngeentlobo zeplastiki zinyibilike kwaye zifake iplastiki kwisibini seentloko zokufa, ukulungiswa kweefilimu ezidityanisiweyo zendlela yokubumba. Iifilimu ezidityanisiweyo ze-co-extruded barrier zihlala zenziwe ngokudibanisa iiplastiki ezidityanisiweyo, iiplastiki ze-polyolefin kunye nee-resin ezinamathelayo zeentlobo ezintathu eziphambili zezinto, ii-resin ezidityanisiweyo ikakhulu yi-PA, EVOH, PVDC, njl.

Ezi zinto zingentla zizinto zokupakisha eziqhelekileyo kuphela, eneneni, ubuncinane ukusetyenziswa kwe-oxide vapor coating, i-PVC, i-PS, i-PEN, iphepha, njl.njl., kunye ne-resin efanayo ngokweendlela ezahlukeneyo zokucubungula, iifomyula ezahlukeneyo zinokuveliswa ngokuguqulwa kweempawu ezahlukeneyo zokusebenza kwezinto zefilimu. Ukulayita kweefilimu ezahlukeneyo ezisebenzayo, ngokusebenzisa i-dry lamination, i-solvent-free lamination, i-extrusion lamination kunye nezinye iteknoloji ezidibeneyo ukuvelisa izixhobo zokupakisha eziguquguqukayo ezisebenzayo ukuhlangabezana neemfuno ezahlukeneyo.iimvelisoukupakishwa.
