Cov tshuaj pleev ib ce yog tshuaj lom neeg thiab feem ntau muag tib lub sijhawm: cov tshuaj tsw qab, cov roj yam tseem ceeb thiab cov surfactants tua cov ntim ntawm sab hauv, thaum oxygen, noo noo thiab lub teeb tawm tsam cov khoom los ntawm sab nraud. Aluminium ntawv ci daws ob qho tib si cov lus qhia ntawm qhov teeb meem vim hais tias ib txheej hlau txuas ntxiv yog qhov cuam tshuam rau cov dej vapor, oxygen thiab lub teeb. Kev siv zog engineering yog nyob rau hauv laminate nyob ib ncig ntawm cov ntawv ci, lub foob uas kaw lub pob thiab cov ntaub ntawv pov thawj uas txhawb nqa cov ntawv tiav.
Barrier Requirements nyob rau hauv ib pob khoom kom zoo nkauj
Cov ntawv ci laminate rau cov tshuaj pleev ib ce, cov tshuaj pleev thiab cov gels feem ntau tau teev tseg kom ua kom cov dej vapor kis tau qis dua 0.02 g / m² / hnub, uas tiv thaiv cov txheej txheem kom qhuav los yog noj cov dej noo ntau dua - xyoo txee lub neej. Barrier kev ua tau zoo yog cov cuab yeej ntawm tag nrho cov qauv es tsis yog cov ntawv ci ib leeg:
Aluminium core txheej: thaiv cov dej noo, oxygen thiab UV lub teeb, nrog tuab xaiv rau kev sib sib zog nqus.
Sealant txheej: lub tshav kub-polymer sealable uas khi rau nws tus kheej thiab nqa lub tev lub zog specification.
Txheej txheej luam tawm: feem ntau 12 µm polyester, xaiv rau qhov ruaj khov thiab siab - kev daws teeb meem branding.
Adhesive system: yuav tsum dhau qhov kev sib tw txuas ntxiv, suav nrog 72-teev kev sib cuag nrog cov roj tseem ceeb, tsis muaj delamination lossis tsiv teb tsaws.
Cov txheej txheem ua haujlwm: lub tshuab nqus tsev- tso cov pob tshab oxide txheej ntxiv UV tshuaj xyuas qhov twg yuav tsum muaj lub qhov rais ntshiab.
Material Stack-Up rau Tubes, Sachets thiab Pouches
Each pack format uses a different balance of formability, stiffness and barrier, and the laminate should be specified from the filling process backwards.
| Hom ntawv | Hom ntawv ci gauge | Kev thov tseem ceeb | Tsim qhov tshwm sim |
|---|---|---|---|
| Txias -formable sachet | 20-30 µm | Puncture kuj thaum lub sij hawm filling | Ntawv nyiaj sib txuas rau ib txheej sealing uas muaj sia nyob flexing |
| Laminated tube | 20-30 µm | Nyem rov qab thiab thaiv | Stiffer txheej zaj duab xis ntxiv rau ib tug barrier core |
| Sawv-p hnab | 20-30 µm | Tso lub zog thiab luam tawm zoo | Ntau- txheej txheej nrog thaj tsam gusset foob |
| Ib - koob tshuaj sachet | 20-30 µm | Tsawg preservative xav tau | Hermetic foob hloov ntau - siv lub thawv |
Sealing, Tamper pov thawj thiab Cleanroom Control
Kev tswj kev kis kab mob pib ntawm lub foob. Hermetic thaum tshav kub kub sealing yuav tsum ncav cuag tev lub zog siab tshaj 5 N / 15 hli kom cov pa microbes tsis tuaj yeem txav los ntawm qhov kaw, thiab induction-cov ntaub qhwv nrog cov npuas dej rov qab muab qhov pom, tsis pom kev cuam tshuam thaum lub pob qhib thawj zaug. Los tiv thaiv- cov txheej txheem zoo li qub txwv tsis pub cov khoom tuaj tos- thaum lub sijhawm siab - nrawm puv, thiab ib zaug - cov hnab ntim tshuaj txo cov kev xav tau ntau dua piv nrog ntau- siv jars vim tias cov txheej txheem tsis rov ua dua - huab cua.
Qhov twg lub pob yog tsim rau kev lag luam tswj hwm, lamination thiab lub hnab ua yog khiav hauv chav huv nrog cov ntaub ntawv saib xyuas kev nyiam huv. Kev tsim khoom kom paub txog kev tsim khoom zoo rau cov khoom ntim khoom tseem ceeb txhawb nqa cov ntaub ntawv ntawd.
Sustainability tsis poob qhov thaiv
Cov khoom thaiv ntawm aluminium yog qhov nyuaj los hloov qhov tam sim no, yog li feem ntau cov kev ntseeg tau txo qis aluminium loj lossis txhim kho qhov kawg - ntawm - lub neej tuav ntau dua li tshem tawm cov txheej hlau.
Mono-cov khoom siv polypropylene nrog nyias aluminium oxide barrier khaws cov khoom thaiv thaum tso cai rau cov pob ua tiav hauv ib qho kwj dej.
Bio-raws li polyethylene foob txheej txo cov fossil carbon hneev taw ntawm laminate.
Compostable polymer films tau ntawv pov thawj rau industrial composting tawg nyob rau hauv kwv yees li 180 hnub nyob rau hauv cov chaw tswj.
Daim ntawv-raws li laminates nrog cov ntawv nyias nyias lossis oxide txheej txiav tag nrho cov khoom hnyav hauv cov ntim khoom thib ob.
Kev ntsuas lub neej tsis tu ncua qhia tau hais tias kev siv dej qis dua rau cov ntawv ci laminates dua li cov khoom siv ntau-txheej txheem.
Kev cai txwv thiab kev kuaj kev tsiv teb tsaws chaw
Kev ua raws cai yog ua kom pom ntawm cov ntawv tiav, tsis yog ntawm cov ntawv ci. Cov txheej txheem cuam tshuam suav nrog EU plastics tsiv teb tsaws txwv rau ncaj qha -cov ntaub ntawv tiv tauj, EU cov khoom lag luam kev nyab xeeb kev nyab xeeb, USP<661>extractables kuaj rau kws tshuaj thiab qhov ncauj- ntim kev saib xyuas, thiab GB 4806 series rau ncaj qha- cov ntaub ntawv tiv tauj ntawm Suav lag luam, ua tiav los ntawm Kev Tswj Xyuas Kom Zoo Nkauj thiab Kev Tswj Xyuas Kev Tswj Xyuas. Nyiv siv qhov zoo - cov kab ntawv teev npe coj mus rau - tiv tauj cov khoom ntim polymers. Cov neeg muag khoom yuav tsum muaj peev xwm muab cov ntaub ntawv kuaj kev tsiv teb tsaws chaw, cov ntaub ntawv extractables thiab cov ntaub ntawv pov thawj uas cov laminate ua tau raws li qhov xav tau kev sib cuag es tsis yog cov lus tshaj tawm dav dav.
Cov lus nug nquag
Q: Yuav ua li cas dej vapor kis tus nqi yuav tsum tau ib tug cosmetic foil laminate ntsib?
Rau cov tshuaj pleev, cov tshuaj pleev thiab cov gels, qis dua 0.02 g / m² / hnub yog lub hom phiaj tshwj xeeb, ntsuas ntawm cov laminate tiav es tsis yog ntawm cov ntawv ci ib leeg.
Q: Vim li cas cov ntawv ci ua ke nrog polyester txheej txheej?
Lub 12 µm polyester txheej muab kev luam tawm, qhov ruaj khov thiab ua haujlwm tsis zoo, yog li siab - kev daws teeb meem muaj sia nyob sau, xa khoom thiab txee tuav yam tsis muaj kev puas tsuaj rau lub hauv paus tseem ceeb.
Q: Cov ntaub ntawv pov thawj tamper ua rau hauv cov ntawv ci li cas?
Ib qho induction-cov ntaub ntawv kaw uas txuas nrog lub npuas npuas rov qab tsis tuaj yeem rov ua dua thaum qhib, yog li txhua qhov kev sib cais tseem pom rau cov neeg siv khoom thiab muab qhov yooj yim, txhim khu kev qha ntawm kev nkag mus ua ntej.
Q: Puas yog mono-cov ntaub ntawv qauv sib phim rau cov ntawv ci laminate rau kev thaiv?
Cov qauv polypropylene nrog nyias aluminium oxide txheej mus txog qhov dej noo ntawm cov pa laminate thaum tseem tshuav nrog ib qho kev rov ua dua tshiab, txawm tias cov pa oxygen thiab kev tiv thaiv lub teeb feem ntau qis dua nrog cov ntawv ci tag nrho.
Q: Qhov kev ntsuam xyuas twg txhawb nqa kev lees paub kev tsiv teb tsaws chaw?
Kev kuaj kev tsiv teb tsaws chaw raws li kev sib cuag lub pob yuav pom, ntxiv rau kev tshuaj ntsuam xyuas thiab cov ntaub ntawv pov thawj ntawm laminate muaj pes tsawg leeg, muab cov ntaub ntawv taug qab uas cov tswj hwm thiab cov tswv lag luam xav tau.
Q: Puas yog ib daim ntawv xov xwm thinner txo qhov cuam tshuam kev ua haujlwm?
Tsis yog rau cov dej vapor los yog lub teeb, vim hais tias ib txheej hlau txuas ntxiv yog ib qho kev txwv tsis pub, tab sis cov kev ntsuas nyias nyias txo qhov kev sib tsoo thiab kev sib tw, yog li qhov ntsuas qhov tsawg kawg yog tsim los ntawm kev tsim thiab sau cov txheej txheem.
