1. Sebopeho sa Boitsebiso: PET / CPE Composite Film
(1) PET Layer (Polyethylene Terephthalate)
- Mosebetsi: E fana ka matla a phahameng, ho hanyetsa mocheso, le pepenene e phahameng.
- Litšobotsi:
- Ho hanyetsa mocheso: Sebaka se qhibilihang ~ 250 ° C, se ka mamella ho pepeseha ha nako e telele ho 121 ° C mouoane.
- Thepa ea Mechini: Matla a matla a phahameng, a hananang le ho robeha, a loketse mechini ea ho paka ka lebelo le holimo.
- Thepa ea Barriers: Sethibelo se setle sa oksijene le mouoane oa metsi, se eketsang bophelo ba li-noodle.
(2) CPE Layer (Chlorinated Polyethylene)
- Mosebetsi: E fana ka ts'ebetso e bonolo le e tiisang mocheso, ho netefatsa botšepehi ba tiiso ea ho paka.
- Litšobotsi:
- Ho tiisetsoa ha Mocheso: Ho tiisa mocheso o tlase (110-130 ° C), e loketseng mechini ea ho paka ka boiketsetso.
- Khanyetso ea Lik'hemik'hale: E hanana le li-acids le alkalis, e thibela ho kenella ha oli ea noodle.
- Ho feto-fetoha ha maemo: E ntlafatsa ho brittleness ea PET, e fokotsa kotsi ea ho phatloha ha liphutheloana.

2. Likopo: Sephutheloana sa Mocheso o Phahameng oa Mouoane oa Noodle
- Ho Sterilization ea Mocheso o Phahameng (95-121°C): E loketse li-noodle tsa hang-hang, udon, ramen, le li-noodle tse ling tse hlokang ho bolaoa ka mouoane.
- Tšireletso ea Lithibelo: E thibela oxidation le ho monya mongobo, e lelefatsa bophelo ba sethala (likhoeli tse 6-12).
- Packaging e Ikemetseng: E lumellana le mechini ea ho paka e otlolohileng, li-vacuum sealers, le likhoele tse ling tsa tlhahiso ea lebelo le holimo.

✅ E hanana le mouoane o phahameng oa mocheso (121°C)
✅ Lintho tse phahameng tsa thibelo (mongobo le ho hanyetsa oksijene)
✅ Matla a matla a mochini (a loketseng ho paka ka lebelo le holimo)
✅ E theko e tlaase, e leka-lekaneng hantle ea ts'ebetso le theko
5. Litlhahiso tsa Kopo
- Packaging ea Mocheso o Phahameng oa Mocheso: Etsa bonnete ba hore lera la CPE le hanana le mongobo le mocheso ho thibela delamination.
- Ntlafatso ea Tiiso ea Mocheso: Fetola mocheso oa ho tiisa (110-130°C) le khatello bakeng sa matla a nepahetseng a tiiso.
- Teko ea Sterilization: Etsa 121°Liteko tsa C/30min tsa sterilization ho netefatsa bots'epehi ba sephutheloana
Ka kopo, romella lipotso bakeng sa lintlha tse ling le khotheishene.
