Ifilimu Yokupakisha Ngokwezifiso Ephrintiwe Ifilimu Yesikhwama Se-Noodle Yokufaka Ifilimu Umusi onengcindezi ephezulu ku-95 ukuya ku-121 ℃
Amafilimu okupakisha ama-noodle adinga ukumelana nokuvalwa kwesitimu esisezingeni eliphezulu (95-121°C), izakhiwo zokuvimba okuphezulu (umswakama nokumelana komoyampilo), ukusebenza okuhle kakhulu kokuvalwa kokushisa, namandla emishini ukuze kuqinisekiswe ubusha besikhathi eside nokuhambisana nemigqa yokukhiqiza yokupakisha ezenzakalelayo.
Impahla eyinhlanganisela ye-PET/CPE iyinketho efanelekile yokupakishwa kwenoodle enezinga lokushisa eliphezulu ngenxa yokusebenza kwayo okuvelele.

1. Isakhiwo Sezinto: Ifilimu ye-PET/CPE eyinhlanganisela
(1) I-PET Layer (I-Polyethylene Terephthalate)
- Umsebenzi: Inikeza amandla aphezulu, ukumelana nokushisa, nokucaca okuphezulu.
- Izici:
- Ukumelana Nokushisa: Indawo yokuncibilika ~250°C, ingamelana nokuchayeka isikhathi eside ku-121°C isitimu.
- Izakhiwo Zemishini: Amandla aphezulu aqinile, amelana nokuphuka, afanele imishini yokupakisha enesivinini esikhulu.
- Izakhiwo Zesithiyo: Isithiyo esihle kakhulu somoya-mpilo kanye nomhwamuko wamanzi, esinweba impilo yeshalofu le-noodle.
(2) Isendlalelo se-CPE (I-Chlorinated Polyethylene)
- Umsebenzi: Ihlinzeka ngokuguquguquka nokusebenza kokuvalwa kokushisa, iqinisekisa ubuqotho bophawu lokupakisha.
- Izici:
- Ukuvalwa Kokushisa: Ukuvalwa kwezinga lokushisa eliphansi (110-130 ° C), kulungele imishini yokupakisha ezenzakalelayo.
- Ukumelana Namakhemikhali: Ukumelana nama-acids nama-alkali, kuvimbela ukungena kwamafutha e-noodle.
- Ukuguquguquka: Kuthuthukisa ukuqina kwe-PET, kunciphisa ingozi yokuqhekeka kokupakisha.

2. Izinhlelo zokusebenza: Ukupakishwa kwe-Steam Noodle Esezingeni Eliphezulu
- Ukuvalwa Kwezinga Lokushisa Okuphezulu (95-121°C): Ifanele ama-noodle asheshayo, i-udon, i-ramen, namanye ama-noodle adinga ukuvalwa kwesitimu.
- Ukulondolozwa Kwezithiyo: Kuvimbela ukumuncwa kwe-oxidation nokumuncwa komswakama, kunwebe impilo yeshalofu (izinyanga eziyi-6-12).
- Ukupakisha Okuzenzakalelayo: Ihambisana nemishini yokupakisha eqondile, ama-vacuum sealers, neminye imigqa yokukhiqiza enesivinini esikhulu.
3.Izinkomba Zokusebenza Ezibalulekile
| Impahla | Izinga Lokuhlola | Inani Elijwayelekile |
| Ukumelana Nokushisa | I-ASTM D638 | Ukumelana nesikhathi eside ku-121°C umusi |
| Amandla Seal Okushisa | I-ASTM F88 | ≥1.5N/15mm |
| I-QTR | I-ASTM D3985 | ≤30 cm³/m²·ngosuku |
| I-WVTR | I-ASTM F1249 | ≤10 g/m²·ngosuku |
| Amandla Okuqina | I-ASTM D882 | ≥100 MPa (PET ungqimba) |
4.Izinzuzo ze-PET/CPE:
✅ Imelana nezinga lokushisa eliphezulu (121°C)
✅ Izakhiwo ze-Superior barrier (umswakama nokumelana ne-oxygen)
✅ Amandla emishini amahle kakhulu (afanele ukupakishwa ngesivinini esikhulu)
✅ Ingabizi, ibhalansi enhle yokusebenza kanye nentengo
5. Izincomo Zokusebenza
- I-High-Temperature Steam Packaging: Qinisekisa ukuthi ungqimba lwe-CPE lumelana nomswakama nokushisa ukuvimbela ukubola.
- Ukwenziwa Kwesici Sokushisa: Lungisa izinga lokushisa lokuvala (110-130°C) kanye nengcindezi yamandla ophawu alungile.
- Ukuhlolwa Kwenzalo: Yenza 121°Ukuhlolwa kokuvala inzalo kwesitimu kwe-C/30min ukuze kuqinisekiswe ubuqotho bephakheji
