Umqulu wesiko wokuPakisha ifilimu eprintiweyo yeNoodle Bag yokuPakisha Ifilim enoxinzelelo oluphezulu lomphunga kwi-95 ukuya kwi-121 ℃
Iifilimu zokupakisha ze-Noodle zifuna ukuchasana nobushushu obuphezulu be-sterilization (95-121 ° C), iimpawu zokuthintela okuphezulu (ukufuma kunye nokumelana ne-oksijini), ukusebenza kakuhle kokutywinwa kobushushu, kunye namandla omatshini wokuqinisekisa ukutsha kwexesha elide kunye nokuhambelana nemigca yokuvelisa ukupakisha ngokuzenzekelayo.
Izinto ezihlanganisiweyo ze-PET/CPE lukhetho olufanelekileyo lokupakishwa kwe-noodle enobushushu obuphezulu bobushushu ngenxa yokusebenza kwayo okugqwesileyo.

1. Ulwakhiwo lweMathiriyeli: PET/CPE iFilimu eDityanisiweyo
(1) PET Umaleko (Polyethylene Terephthalate)
-Umsebenzi: Ibonelela ngamandla aphezulu, ukumelana nobushushu, kunye nokungafihlisi okuphezulu.
- Iimpawu:
- Ukumelana nokushisa: Indawo yokunyibilika ~ 250 ° C, inokumelana nokuchaswa kwexesha elide kwi-121 ° C umphunga.
-IiPropati zoomatshini: Amandla aphezulu okuqina, ukumelana nokuqhekeka, alungele oomatshini bokupakisha besantya esiphezulu.
- IiPropati zoMqobo: I-oksijini egqwesileyo kunye nesithintelo somphunga wamanzi, ukwandisa ubomi beshelufu ye-noodle.
(2) CPE Umaleko (Chlorinated Polyethylene)
- Umsebenzi: Ubonelela ngokuguquguquka kunye nokusebenza kokutywinwa kobushushu, ukuqinisekisa ukupakishwa kwetywina lokuthembeka.
- Iimpawu:
- Ukutywinwa kobushushu: Ukutywinwa kobushushu obuphantsi (110-130 ° C), ifanelekile kumatshini wokupakisha ngokuzenzekelayo.
- Ukumelana neMichiza: Ukumelana ne-acids kunye ne-alkalis, kuthintela ukungena kweoli ye-noodle.
-Ukuguquguquka: Ukuphucula i-PET's brittleness, ukunciphisa ingozi yokupakisha yokuqhekeka.

2. Izicelo: Ukupakishwa kweNoodle yomphunga wobushushu obuphezulu
-I-High-Temperature Sterilization (95-121 ° C): Ifanelekile kwi-noodles ekhawulezileyo, i-udon, i-ramen, kunye nezinye ii-noodle ezifuna inzalo yomphunga.
- Ukugcinwa komqobo: Ikhusela i-oxidation kunye nokufunxa ukufuma, ukwandisa ubomi beshelufu (iinyanga ezi-6-12).
- Ukupakishwa okuzenzekelayo: Iyahambelana noomatshini bokupakisha ngokuthe nkqo, abatywini be-vacuum, kunye neminye imigca yemveliso enesantya esiphezulu.
3.Izalathisi zoMsebenzi oPhambili
| Ipropati | Umgangatho woVavanyo | Ixabiso eliqhelekileyo |
| Ukumelana nobushushu | I-ASTM D638 | Ukuchasana kwexesha elide ukuya kwi-121 ° C umphunga |
| Amandla etywina lobushushu | I-ASTM F88 | ≥1.5N/15mm |
| QTR | I-ASTM D3985 | ≤30 cm³/m²·usuku |
| WVTR | I-ASTM F1249 | ≤10 g/m²· ngosuku |
| Tensile strength | I-ASTM D882 | ≥100 MPa (PET umaleko) |
4.Izinto eziluncedo zePET/CPE:
✅ Ukumelana nomphunga wobushushu obuphezulu (121°C)
✅ Iimpawu eziphezulu zomqobo (ukufuma kunye nokumelana ne-oxygen)
✅ Amandla omatshini agqwesileyo (afanelekile ukupakishwa ngesantya esiphezulu)
✅ Indleko-esebenzayo, ibhalansi elungileyo yokusebenza kunye nexabiso
5. Iingcebiso ngesicelo
-I-High-Temperature Steam Packaging: Qinisekisa ukuba umaleko we-CPE uyaxhathisa ukufuma kunye nobushushu ukunqanda ukubola.
-Ukuphuculwa kweSitywina soBushushu: Lungisa ubushushu bokutywina (110-130°C) kunye noxinzelelo lwamandla etywina afanelekileyo.
- Uvavanyo lokuvala inzala: Yenza i-121°C/30min iimvavanyo zokuvala umphunga ukuqinisekisa ingqibelelo yokupakishwa
