Tilmaamaha waxqabadka ee alaabta filimka baakadaha ayaa si toos ah u dhaqaajinaya horumarinta shaqeynta ee alaabta baakadaha dabacsan ee isku dhafan. Kuwa soo socdaa waa horudhac kooban oo ku saabsan sifooyinka shaqaynta ee alaabada baakadaha badan ee la isticmaalo.
1. Qalabka baakadaha sida caadiga ah loo isticmaalo: filimka PE
Qalabka PE-da ee kulaylka lagu dabooli karo waxay ka soo baxeen filimo hal-lakab ah oo la afuufay ilaa filimo badan oo isku dhafan, si qaababka lakabyada gudaha, dhexe iyo dibadda loo qaabeeyo si kala duwan. Naqshadeynta caanaha isku dhafka ah ee noocyada kala duwan ee resins polyetylen waxay soo saari karaan heerkul kala duwan oo heerkulbeeg ah, heerkulbeeg kuleyl ah oo kala duwan, sifooyinka wasakheynta ka-hortagga ee kala duwan,hAwoodaha xabagta, saamaynta anti-static, iwm, si loo daboolo shuruudaha baakadaha alaabta gaarka ah iyo walxaha filimka PE oo leh astaamo kala duwan oo shaqeynaya.
Sanadihii la soo dhaafay, filimada bixially oriented polyethylene (BOPE) ayaa sidoo kale la sameeyay, kuwaas oo wanaajinaya xoogga jilicsanaanta filimada polyetylen waxayna leeyihiin awood sare oo kuleyl ah.
2. Qalabka Filimka CPP
Qalabka CPP waxaa caadi ahaan loo isticmaalaa BOPP / CPP qaab dhismeedka baakadaha iftiinka-caddaynta, laakiin qaababka kala duwan ee CPP-ga ayaa sidoo kale laga samayn karaa sifooyin shaqo oo kala duwan oo filimka ah, sida caabbinta heerkulka-hooseeya, caabbinta heerkulka sare ee heerkulka, heerkulka hoose ee daboolka, xoogga dalool ee sare, caabbinta daxalka, iyo sifooyinka kale ee shaqeyn ee alaabta kulaylka.
RSannadihii ugu dambeeyay, warshaduhu waxay sidoo kale soo saareen filim matte ah oo CPP ah, oo kordhinaya saameynta muuqaalka muuqaalka ee bacaha filimka CPP ee hal lakab ah.
3. Qalabka filimka BOPP
Baakadaha fudud ee filimka isku dhafan ayaa inta badan loo isticmaalaa filimka caadiga ah ee BOPP iftiinka iyo filimka BOPP matte, waxaa sidoo kale jira filimka kuleylka BOPP (hal dhinac ama laba-geesood oo kulaylka ah), filimka BOPP luul.
BOPP waxaa lagu gartaa xoog xoog badan (ku haboon daabacaadda midabada badan), sifooyinka uumiga biyaha oo aad u fiican, oo si ballaaran loo isticmaalo baakadaha iftiinka qoyaanka u adkaysta ee wejiga alaabta daabacan.
Filimka BOPP matte oo leh saameyn qurxin matte ah oo la mid ah warqadda. Filimka BOPP ee kuleyliyaha ayaa loo isticmaali karaa sidii qalab hal lakab ah, sida in lagu duubo baakadaha gudaha ee nacnaca. Filimka BOPP ee luul ah waxaa inta badan loo isticmaalaa baakadaha barafka-cream-kuleelka walxaha lakabka daboolaya, wuxuu badbaadin karaa daabacaadda khad cad, cufnaantiisa hoose, 2 ilaa 3N / 15mm xoogga xiridda si ay bacdu u fududaato in la furo si loo soo saaro waxa ku jira.
Intaa waxaa dheer, sida filimka BOPP anti-fog, filimka holographic OPP laser, warqad synthetic PP, filimka BOPP ee biodegradable iyo taxane kale oo BOPP ah oo filimo shaqeynaya ayaa sidoo kale la faafiyey oo lagu dabaqay heer gaar ah.
4. Qalabka baakadaha sida caadiga ah loo isticmaalo: Qalabka filimka PET
Filimka caadiga ah ee 12MICRONS PET iftiinka ayaa si weyn loogu isticmaalaa baakadaha jilicsan ee isku dhafan, xoogga farsamada ee alaabteeda baakadaha la dhejiyay ayaa aad uga sarreeya alaabta isku dhafan ee BOPP laba-lakab ah (wax yar ka hooseeya alaabta BOPA double-lakabka ah), iyo awoodda xannibaadda oksijiinta ee BOPP / PE (CPP) filimka isku dhafan si loo yareeyo 30 jeer.
Cadaadiska kulaylka ee alaabta PET waa mid aad u wanaagsan, waxaana lagu samayn karaa dabaqa bacaha wanaagsan. Filimka kulaylka PET, matte PET PET filimka kulaylka yareeya, filimka matte PET, filim polyester-ka-xad-dhaaf ah, filimka PET maroojin, filim toosan PET filim iyo alaabooyin kale oo shaqeynaya ayaa sidoo kale la isticmaalaa.
5. Qalabka baakadaha caadiga ah: filimka naylon
Filimka naylon ee ku jihaysan Biaxial waxaa si weyn loogu isticmaalaa faakuum, karkarinta iyo bacaha uumiga xooggiisa sare, caabbinta dalool sare, iska caabin heerkul sare ah iyo xannibaad oksijiin oo wanaagsan.
Inta badan boorsooyinka dahaaran ee awoodda-weyn ee ka sarreeya 1.7kg waxay sidoo kale u isticmaalaan qaab-dhismeedka BOPA//PE si ay u adkaystaan hoos u dhaca wanaagsan.
Filimka naylon, oo si weyn looga isticmaalo Japan baakadaha cuntada la qaboojiyey, kaas oo leh iska caabin heerkul hooseeya oo wanaagsan, yaraynta heerka jebinta bacda inta lagu jiro kaydinta heerkulka hooseeya iyo gaadiidka.
6. Qalabka Baakadaha Caadiga ah: Daahan aluminium ah Filim bir ah
Aluminium Vacuum wuxuu ku jiraa filimka (sida PET, BOPP, CPP, PE, PVC, iwm.) dusha sare ee samaynta lakabka lakabka aluminium cufan, sidaas darteed si weyn u kordhinaysa filimka biyaha uumiga, oksijiinta, awoodda xannibaadda iftiinka, inta badan loo isticmaalo baakadaha dabacsan VMPET, qalabka VMCPP.
VMPET oo loogu talagalay laminating saddex-lakab ah, VMCPP oo loogu talagalay laminating laba-lakab ah.
Qaab dhismeedka OPP//VMPET//PE ayaa hadda si qaan-gaar ah loogu isticmaalay khudaarta jaraa'idka, oo ka soo baxda baakadaha vacuum ee karkaraya. Qaab dhismeedka PE ayaa hadda si qaan-gaar ah loo dabaqay si loo tuujiyo khudaarta, sprouts ee baakadaha vacuum karkaraya, si looga gudbo cilladaha alaabta aluminium caadiga ah, lakabka aluminium fudud si ay u haajiraan, ha iska caabin cilladaha ee karkaraya, horumarinta alaabta VMPET oo leh nooca hoose ee daahan, ka hor iyo ka dib markii karkaraya ee diirinta xoogga ah ee ka badan / 1mm aluminium, muuqan ma 5. waxqabadka guud ee xannibaadda bacda.
7. Qalabka wax lagu duubo ee caadiga ah: Aluminium foil
Foornada aluminium ee baakadaha dabacsan guud ahaan waa 6.5μm ama 9μm 12microns dhumucdiisuna, bireed aluminium aragti ahaan waa wax caqabad sare ah, permeability biyaha, permeability oxygen, permeability iftiinka yihiin "0", laakiin dhab ahaantii waxaa jira pinholes in bireed aluminium iyo laalaabida caabbinta pinhole liidata, waxaa jira tiro ka mid ah saamaynta baakadaha caqabad dhab ah ma fiicna. Furaha codsiga ee aluminium aluminium waa in laga fogaado godad fiiqan inta lagu jiro farsamaynta, baakadaha iyo gaadiidka, sidaas darteed hoos u dhigista awoodda dhabta ah. Sanadihii la soo dhaafay, waxaa jira u janjeera in alaabta aluminium aluminium lagu beddelo alaabta baakadaha dhaqaale badan ee aagagga codsiga dhaqameed.

Inta badan filimka dahaarka ah ee PVDC (filimka dahaadhka K), filimka dahaarka ah ee PVA (filim dahaarka ah).
PVDC waxay leedahay xannibaad oksijiin ah oo heer sare ah iyo iska caabin qoyaan, waxayna leedahay daahfurnaan aad u fiican, filimka PVDC ee daboolan ee loo isticmaalo filimka salka ayaa inta badan ah BOPP, BOPET, BOPA, CPP, iwm.
9. Qalabka Baakadaha Caadiga ah: Filimada Barrier-ka Sare ee Wadajirka ah
Co-extrusion waa laba ama in ka badan oo caag ah oo kala duwan, iyada oo loo marayo laba ama in ka badan laba extruders, siday u kala horreeyaan, si noocyo kala duwan oo caag ah dhalaalaysa iyo balaastiga loogu talagalay lammaane dhinta madaxa, diyaarinta filimada isku dhafan ee habka qaabaynta. Filimada isku-dhafka ah ee xannibaadda ee isku-dhafka ah ayaa badanaa laga sameeyaa isku-darka caagagga xannibaadda, balaastikada polyolefin iyo xabagta koollada ee saddexda nooc ee ugu waaweyn ee alaabta, resins barrier inta badan waa PA, EVOH, PVDC, iwm.
Kor ku xusan waa kaliya alaabta baakadaha caadiga ah, dhab ahaantii, ugu yaraan isticmaalka daahan uumiga oxide, PVC, PS, PEN, warqad, iwm, iyo xabagta la mid ah sida ay hababka processing kala duwan, formulations kala duwan la soo saari karaa by wax ka beddelka sifooyinka functional kala duwan ee alaabta filimka. Lamination ee filimaan kala duwan oo shaqeynaya, iyada oo loo marayo lamination qalalan, lamination-free lamination, extrusion lamination iyo tiknoolajiyada kale ee isku dhafan si loo soo saaro qalab baakad dabacsan oo shaqeynaya si loo daboolo baahiyaha kala duwanalaabtabaakad
