Vim li cas Dawb Hloov Amber lossis Clear?
Ntau cov photosensitive active xav tau kev tiv thaiv los ntawmob leegUV / pom lub teebthiabya raws. Cov kev xaiv dav dav muaj kev sib pauv:
Amber PVC/PVDC- thaiv UV zoo tab sis tso cai rau qee lub teeb pom kev (10-20% kis tau tus mob). Tsis tas li ntawd amber xim ua rau pom kev soj ntsuam ntawm kev sau qib nyuaj.
Clear nrog UV-block additive- feem ntau tsis thaiv lub teeb pom kev (400-700 nm), uas tuaj yeem degrade qee cov molecules (xws li riboflavin, amiodarone).
Ntawv nyiaj- zoo heev thaiv thiab lub teeb thaiv, tab sis opaque (tsis muaj cov khoom pom) thiab kim.
Peb dawb PVC / PVDC- titanium dioxide pigment tawg tag nrho cov wavelengths. Tsis muaj teeb pom kev. Txawm li cas los xij, tom qab dawb muaj qhov sib txawv siab rau kev luam tawm thiab yooj yim tshuaj xyuas ntawm cov ntsiav tshuaj muaj nyob (koj pom silhouette). Tus nqi tsuas yog 10-15% saum toj no meej, deb hauv qab ntawv ci.
Cov Nta Tseem Ceeb – Tsim los rau Photosensitive Actives
Tag nrho lub teeb thaiv- TiO₂ loading ntawm 12% los ntawm qhov hnyav. UV-vis spectrophotometer qhia<1% transmission from 200 nm to 700 nm at 250 µm thickness. Your drug sees zero photons.
Moisture barrier los ntawm PVDC- WVTR tsawg li 1.5 g / m²·hnub, tiv thaiv hygroscopic actives (piv txwv li, ACE inhibitors, probiotics).
Tsis muaj pigment migration- TiO₂ yog encapsulated hauv PVC matrix. Tsis muaj plua plav lossis hloov mus rau cov cuab yeej sealing.
High whiteness khaws cia- Cov qauv tsis daj, txawm tias tom qab kev laus sai (60℃/ 75% RH rau 6 lub hlis, ΔE<2).
Zoo sib xws print- Dawb tom qab ua rau dub lossis xim ntau tus lej nyeem tau zoo heev. Barcode scanners nyeem tau yooj yim.
Tib formability li ntshiab PVC- Tsis muaj kev hloov pauv hauv cov cuab yeej lossis cov txheej txheem. Kos qhov tob txog li 12 mm.

Tsis pom zoo rau:
Cov khoom lag luam uas yuav tsum tau kuaj pom los ntawm lub hlwv (xws li, cov ntsiav tshuaj coated nrog luam ntawv). Siv ntshiab nrog UV thaiv.
Deep drawn (>14 hli) kab noj hniav - PVC dawb yuav nyias ntawm cov ces kaum, txo lub teeb thaiv. Peb pom zoo kom nce lub hauv paus thickness.
Quality Assurance – Lub teeb thaiv kev sib raug zoo
In-line spectrophotometer:
Txhua tus tswv yob dhau los ntawm dual-beam UV-vis scanner. Peb ntsuas kev sib kis ntawm 365 nm (UVA), 450 nm (xiav pom), thiab 650 nm (pom liab).
Kev lees txais cov qauv:
A365 <1.5%
A450 <6%
A650 <6%
Yog tias ib qho yob tshaj, nws raug tsis lees paub lossis txo qis rau "qib kev lag luam."
Pigment Dispersion Test:
We take cross‑sections of each batch and examine under microscope (400x). TiO₂ agglomerates >10 µm cause pinholes and uneven whiteness. Our specification: >95% ntawm cov khoom<5 µm.
WVTR verification for white film:
Cov xim muaj peev xwm qee zaum tsim micro-voids uas ua rau kom muaj kev sib kis ntawm cov dej noo. Peb sim txhua pawg ntawm MOCON. Yog tias WVTR tshaj 2.5 g / m²·hnub, peb rov qab nrog PVDC ntxiv.
Khaws cov qauv kev pab cuam:
Peb khaws 1 m² qauv los ntawm txhua qhov ntau hauv lub txee tsaus. Koj tuaj yeem thov nws rau lub sijhawm ntev lub teeb ruaj khov kev sib raug zoo.
Factory & Manufacturing – Dawb Qib Specifications
Dedicated dawb compounding kab- Tsis muaj xim sib kis nrog cov qhab nia ntshiab lossis amber.
Titanium dioxide qhov chaw- Qib Rutile (tsis yog anatase), FDA- npe, los ntawm ib tus neeg muag khoom (Kronos lossis Chemours) rau kev sib koom ua ke.
PVDC txheej rau dawb substrate- Dawb PVC muaj zog dua me ntsis; peb kho corona kho rau 48 dynes / cm rau adhesion.
Cleanroom slitting- ISO 7. Cov yeeb yaj kiab dawb pom cov plua plav yooj yim; peb siv ionized cua riam kom tshem tawm cov khoom ua ntej winding.

Tsis ntev los no peev: A X-ray fluorescence (XRF) kabuas ntsuas TiO₂ concentration hauv lub sijhawm. Lub kaw lus tswj tau kho qhov nrawm nrawm yog tias whiteness drifts.
FAQ – Lub teeb-Blocking Dawb Zaj duab xis
Q1: Puas yog cov xim dawb muaj kev nyab xeeb rau kev sib cuag tshuaj?
A: Yes. Titanium dioxide (TiO₂) is listed in FDA 21 CFR 178.3297 (colorants for polymers). It does not migrate; particle size is >100nm, tsis muaj kev txhawj xeeb nanotoxicity. Peb muab daim ntawv pov thawj ntawm kev ua raws li EU 10/2011 Annex I.
Q2: Kuv puas tuaj yeem pom los ntawm lub hlwv los xyuas seb lub ntsiav tshuaj puas ploj lawm?
A: Tsis ncaj qha. Txawm li cas los xij, tom qab dawb tsim ib lub silhouette - koj pom cov duab ntxoov ntxoo ntawm cov ntsiav tshuaj tiv thaiv qhov chaw dawb. Rau cov tshuab tsis pom kev tsis pom kev, peb pom zoo kom rov qab teeb pom kev zoo. Peb muaj ib daim ntawv dawb ntawm qhov pom kev teeb tsa rau cov pob liab liab dawb.
Q3: Puas yog dawb PVC / PVDC raug nqi ntau dua qhov tseeb?
A: Kwv yees li 12-18% siab dua vim TiO₂ thiab nruj QC. Ntau qis dua amber PVC / PVDC (uas siv cov xim kim) thiab deb ntawm cov ntawv ci.
Q4: Yuav ua li cas piv rau amber zaj duab xis rau UV tiv thaiv?
A: Amber typically blocks UV (200–400 nm) but transmits 10–20% of visible light (400–700 nm). White blocks >95% pom lub teeb thiab. Qee cov tshuaj degrade nyob rau hauv lub teeb pom kev (xws li, riboflavin, methylene xiav). Siv dawb rau kev tiv thaiv tiav.
Q5: Puas yog zaj duab xis dawb ua nkig dhau sijhawm?
A: No – TiO₂ does not affect PVC flexibility. After 2 years of ambient storage, elongation remains >180%. Accelerated aging qhia tsis muaj embrittlement.
Q6: Koj puas tuaj yeem luam tawm ntawm sab dawb?
A: Yog. Dawb yog txheej txheej (rov qab luam). Peb tuaj yeem luam tawm txog 8 xim nrog UV-kho inks. Cov ntawv luam tawm tom qab laminated rau PVDC (los yog PVDC coated rau sab nraud). Nug peb qib "print-ready white" qib.
