Thaum tshav kub kub-Stabilized PVC / PE / PVDC Blister Films: Tau tshaj -Tub kub Sterilization & Filling Processes

Thaum tshav kub kub-Stabilized PVC/PE/PVDC Blister Film (HS Series)

Nws yog dab tsi:

Ntau - txheej blister zaj duab xis qhov twg PVC substrate yog compounded nrog ib tug thermally ruaj khov plasticizer system (tsis muaj DEHP, tsis muaj tsawg-migrating esters) thiab PE interlayer muaj xws li ib tug antioxidant pob uas tiv taus kub mus txog 125℃yam tsis muaj degrading. PVDC barrier txheej tseem zoo li qub tom qab ua kom tsis muaj menyuam lossis kub - cov txheej txheem sau.

Vim li cas "heat-stabilized" txawv ntawm tus qauv PVC/PVDC:
Standard PVC pib soften thiab tso plasticizer saum 70 degree. Nyob rau hauv autoclave sterilization (121 degree) los yog kub- filling (95–110 degree), cov pa blister films warp, tig hazy, los yog delaminate. Peb HS series yog tsim los kom muaj sia nyob cov txheej txheem no thaum tswj cov khoom thaiv thiab kev sib khi ruaj khov.

Kev tsim kho:

Txheej txheej:Thaum tshav kub kub-stabilized PVC (hloov nrog polyol-raws li plasticizers + epoxidized soybean roj synergists) - thickness 180–250µm

Nruab nrab txheej:PE nrog siab -kub antioxidant (Irganox 1010 hom, FDA-ua raws) - 25–40µm

Barrier txheej:PVDC (coated rau sab hauv ntawm PVC ua ntej lamination, lossis nruab nrab ntawm PE thiab PVDC nyob ntawm kev txiav txim) - 30-50 g / m²

Sealant txheej:Tsawg-PE density los yog qib peelable - 20–30µm

Tag nrho cov thickness:230-350µm (thicker dua li tus qauv vim qhov yuav tsum tau ua kom sov)

Muaj hom ntawv:

Roll dav: 150-1000mm

Xim: ntshiab, dawb (siab opacity rau lub teeb- cov khoom rhiab heev tom qab sterilization), amber (UV- thaiv)

Cov txheej txheem Sterilization validated:

Chav autoclave (121 degree, 15-30 feeb, saturated steam)

Kub immersion (95 degree, 60 feeb)

Kub filling (95-110 degree, tiv tauj ncaj qha nrog cov khoom)

Ethylene oxide (EtO) - tsis muaj kev cuam tshuam tsis zoo nrog cov stabilizers

Cov txiaj ntsig tseem ceeb (High-Tshav Kub Compatibility yam tsis muaj qhov tsis ua tiav)

Tsis muaj blister warpage tom qab autoclave
Dimensional hloov<1.5% in length and width after 121°C / 30 min steam cycle (ASTM D1204). Standard PVC/PVDC warps 6–12% and often pops out of forming stations.

Zero delamination ntawm PE / PVC interface
The antioxidant in the PE layer prevents oxidation-induced bond failure. Peel strength after sterilization remains >2.8 N/15mm (initial >4.0 N / 15mm). Ntau tus neeg sib tw ua yeeb yaj kiab delaminate tag nrho tom qab ib lub voj voog autoclave.

PVDC barrier tuav tom qab kub kub
Hom PVDC crystallizes thiab tawg nyob rau hauv chav kub. Peb HS txheej siv cov qib amorphous ntau dua nrog cov thermal stability ntau dua. OTR tom qab autoclave: nce ntawm 3.5 mus rau 5.2 cm³ / m²·hnub (vs. standard PVDC: 3.5 txog 18 cm³ / m²·hnub).

Kub- sau tau sib xws yam tsis muaj ua ntej- txias
Sau koj lub hlwv hnab nrog cov khoom ntawm 105℃ncaj qha. Lub tshav kub-stabilized PVC tsis soften los yog sag. Ib lub tuam txhab pharma tshem tawm 20-feeb txias conveyor (txuag hauv pem teb chaw thiab lub zog).

Seal kev ncaj ncees tom qab sterilization - tsis muaj leakers
Cov ntsaws ruaj ruaj ua ntawm 140℃(tus qauv) muaj sia nyob autoclave yam tsis muaj tawg lossis tawg. Peb kuaj lub zog ua ntej thiab tom qab ua kom tsis muaj menyuam: poob qis dua 15% (kev lag luam poob 30-50%).

Extractables nyob qis txawm tias tom qab tshav kub kub
Plasticizer tsiv teb tsaws ( ntsuas los ntawm tag nrho kev tsiv teb tsaws hauv 50% ethanol ntawm 121 degree) yog<6 mg/dm² – well within EU limit of 10 mg/dm². Standard PVC can exceed 12 mg/dm² under same conditions.
