Kanema Wopaka Mwambo Wopaka Kanema Wosindikizidwa wa Noodle Bag Packaging Filimu yothamanga kwambiri pa 95 mpaka 121 ℃
Makanema opaka ma Noodle amafunikira kukana kutentha kwambiri kwa nthunzi (95-121 ° C), zotchinga zazikulu (kunyowa ndi kukana kwa okosijeni), magwiridwe antchito abwino kwambiri osindikizira kutentha, komanso mphamvu zamakina kuti zitsimikizire kutsitsimuka kwanthawi yayitali komanso kugwirizana ndi mizere yopangira ma CD.
Zinthu zophatikizika za PET/CPE ndi njira yabwino yopangira zakumwa zoziziritsa kukhosi zotentha kwambiri chifukwa chakuchita bwino.

1. Kapangidwe kazinthu: PET / CPE Composite Film
(1) PET Layer (Polyethylene Terephthalate)
- Ntchito: Imapereka mphamvu zambiri, kukana kutentha, komanso kuwonekera kwambiri.
- Makhalidwe:
- Kukana Kutentha: Malo osungunuka ~ 250 ° C, amatha kupirira kutentha kwa nthawi yaitali ku 121 ° C nthunzi.
- Katundu Wamakina: Mphamvu zolimba kwambiri, zosagwirizana ndi kusweka, zoyenera pamakina onyamula othamanga kwambiri.
- Katundu Wotchinga: Chotchinga chabwino kwambiri cha okosijeni ndi nthunzi wamadzi, kukulitsa moyo wamashelufu.
(2) CPE Layer (Chlorinated Polyethylene)
- Ntchito: Amapereka kusinthasintha ndi ntchito yosindikiza kutentha, kuonetsetsa kukhulupirika kwa chisindikizo.
- Makhalidwe:
- Kutsekedwa kwa Kutentha: Kusindikiza kutentha pang'ono (110-130 ° C), koyenera kumakina olongedza okha.
- Kukaniza kwa Chemical: Kusamva ma acid ndi alkalis, kumalepheretsa kulowa kwa mafuta a noodle.
- Kusinthasintha: Kumakulitsa brittleness ya PET, kuchepetsa chiopsezo chosweka.

2. Mapulogalamu: Kutentha Kwambiri kwa Steam Noodle Packaging
- Kutentha Kwambiri Kutentha (95-121°C): Ndikoyenera pompopompo Zakudyazi, udon, ramen, ndi Zakudyazi zina zomwe zimafuna kutsekereza nthunzi.
Kuteteza Zotchinga: Kumateteza ma oxidation ndi kuyamwa kwa chinyezi, kukulitsa moyo wa alumali (miyezi 6-12).
- Kupaka Paokha: Kumagwirizana ndi makina onyamula oyimirira, zosindikizira vacuum, ndi mizere ina yothamanga kwambiri.
3.Zizindikiro Zofunika Kwambiri
| Katundu | Test Standard | Mtengo Wodziwika |
| Kukaniza Kutentha | Chithunzi cha ASTM D638 | Kukana kwanthawi yayitali mpaka 121 ° C nthunzi |
| Kutentha kwa Chisindikizo Champhamvu | Chithunzi cha ASTM F88 | ≥1.5N/15mm |
| Mtengo wa QTR | Chithunzi cha ASTM D3985 | ≤30 cm³/m²·tsiku |
| Mtengo WVTR | Chithunzi cha ASTM F1249 | ≤10 g/m²·tsiku |
| Kulimba kwamakokedwe | Chithunzi cha ASTM D882 | ≥100 MPa (PET wosanjikiza) |
4.Ubwino wa PET/CPE:
✅ Kusamva kutentha kwambiri (121°C)
✅ Superior chotchinga katundu (chinyezi & kukana oxygen)
✅ Mphamvu zamakina zabwino kwambiri (zoyenera kulongedza mwachangu)
✅ Zotsika mtengo, zabwinobwino zogwirira ntchito komanso mtengo
5. Malangizo a Ntchito
- Kupaka kwa Mpweya Wotentha Kwambiri: Onetsetsani kuti wosanjikiza wa CPE umalimbana ndi chinyezi ndi kutentha kuti mupewe delamination.
- Kukhathamiritsa kwa Chisindikizo Chakutentha: Sinthani kutentha kosindikiza (110-130°C) ndi kukakamizidwa kwa mphamvu yabwino yosindikizira.
- Kuyesa kwa Sterilization: Chitani 121°Mayeso a C/30min oletsa kutsekereza nthunzi kuti atsimikizire kukhulupirika kwake
Chonde tumizani zofunsira kuti mumve zambiri komanso mawu owerengera.
