PE (Polyethylene)
Mawonekedwe: Kukhazikika kwamankhwala abwino, osakhala ndi poizoni, owonekera kwambiri, komanso osamva dzimbiri ndi ma acid ndi ma alkali ambiri. Kuphatikiza apo, PE imakhalanso ndi chotchinga chabwino cha gasi, chotchinga mafuta ndi kusungirako kununkhira, zomwe zimathandiza kusunga chinyezi muzakudya. Pulasitiki yake ndi yabwino kwambiri, ndipo sikophweka kufooketsa kapena kusweka ngati choyikapo.
Kugwiritsa ntchito: Nthawi zambiri amagwiritsidwa ntchito popaka pulasitiki yazakudya.
PA (Nayiloni)
Mawonekedwe: Kukana kutentha kwakukulu, kukana kutulutsa mpweya, ntchito yabwino yotchinga mpweya, ndipo ilibe zinthu zovulaza. Kuphatikiza apo, zinthu za PA ndizolimba, zosavala, zosagwira mafuta, zimakhala ndi makina abwino komanso olimba, ndipo zimakhala ndi kukana kwabwino kwa nkhonya komanso zina zotsutsana ndi mildew ndi antibacterial.
Kugwiritsa ntchito: Itha kugwiritsidwa ntchito ngati kuyika chakudya, makamaka pazakudya zomwe zimafunikira chotchinga cha oxygen komanso kukana kupuma.
PP (polypropylene)
Mawonekedwe: PP ya kalasi yazakudya sidzatulutsa zinthu zovulaza ngakhale kutentha kwambiri. Pulasitiki ya PP ndi yoonekera bwino, imakhala ndi gloss yabwino, ndiyosavuta kuyikonza, imakhala ndi kung'ambika kwambiri komanso kukana mphamvu, imalimbana ndi madzi, imalimbana ndi chinyezi, komanso kutentha kwambiri, ndipo ingagwiritsidwe ntchito nthawi zonse pa 100 ° C ~ 200 ° C. Kuphatikiza apo, pulasitiki ya PP ndiyo yokhayo yapulasitiki yomwe imatha kuwotchedwa mu uvuni wa microwave.
Ntchito: Nthawi zambiri amagwiritsidwa ntchito m'matumba apulasitiki okhudzana ndi chakudya, mabokosi apulasitiki, ndi zina.
PVDC (polyvinylidene kloride)
Mawonekedwe: PVDC ili ndi kulimba kwa mpweya wabwino, kuwonongeka kwa malawi, kukana dzimbiri, chitetezo ndi kuteteza chilengedwe, ndipo imakwaniritsa zofunikira paukhondo wa chakudya. Kuphatikiza apo, PVDC imakhalanso ndi kukana kwanyengo yabwino ndipo siitha ngakhale itawululidwa panja kwa nthawi yayitali.
Ntchito: Amagwiritsidwa ntchito kwambiri m'zakudya ndi zakumwa.
EVOH (ethylene/vinyl alcohol copolymer)
Mawonekedwe: Kuwonekera bwino ndi gloss, katundu wamphamvu wotchinga mpweya, ndipo amatha kuteteza mpweya kuti usalowe m'mapaketi kuti uwononge ntchito ndi chakudya. Kuphatikiza apo, EVOH imalimbana ndi kuzizira, yosavala, yotanuka kwambiri, ndipo ili ndi mphamvu zapamwamba.
Ntchito: chimagwiritsidwa ntchito aseptic ma CD, zitini otentha, matumba retort, ma CD mkaka, nyama, zamzitini madzi ndi condiments, etc.
Filimu yokhala ndi aluminium (aluminium + PE)
Mawonekedwe: Kanema wokutidwa ndi aluminiyamu ndi zinthu zoteteza chilengedwe. Chigawo chachikulu cha thumba lachikwama chophatikizira ndi chojambula cha aluminiyamu, chomwe ndi siliva-choyera, chopanda poizoni komanso chosakoma, chopanda mafuta komanso chopanda kutentha, chofewa ndi pulasitiki, ndipo chimakhala ndi chotchinga chabwino komanso chosindikizira kutentha. Kuphatikiza apo, filimu yopangidwa ndi aluminiyamu imatha kuletsanso chakudya ku ziphuphu za okosijeni ndikupewa kuipitsidwa ndi chilengedwe, ndikusunga kutsitsimuka komanso kukoma kwa chakudya.
Ntchito: amagwiritsidwa ntchito kwambiri m'munda wa ma CD chakudya.
Kuphatikiza pa zinthu zomwe zili pamwambazi, palinso zinthu zina zophatikizika monga BOPP / LLDPE, BOPP / CPP, BOPP / VMCPP, BOPP / VMPET / LLDPE, etc. Zida zophatikizikazi zimatha kukwaniritsa zosowa zosiyanasiyana za matumba onyamula chakudya pokhudzana ndi kukana chinyezi, kukana mafuta, kudzipatula kwa okosijeni, kutsekereza kuwala, komanso kusungirako fungo la zinthu zosiyanasiyana kudzera mwa kuphatikiza kwa zinthu zosiyanasiyana.
Posankha zinthu zamatumba onyamula chakudya, ndikofunikira kuganizira mozama zinthu monga mawonekedwe a chakudya chomwe chapakidwa, zofunikira pa moyo wa alumali, komanso kufunikira kwa msika. Nthawi yomweyo, ndikofunikira kuwonetsetsa kuti zinthu zomwe zasankhidwa zikukwaniritsa miyezo yoyenera yachitetezo cha chakudya komanso zowongolera.
Nthawi yotumiza: Apr-24-2025
