Iyi ndi gulu la pulasitiki lapadziko lonse lapansi. Manambala osiyanasiyana amasonyeza zinthu zosiyanasiyana. Katatu kozunguliridwa ndi mivi itatu kumasonyeza kuti pulasitiki ya chakudya imagwiritsidwa ntchito. "5″ mu katatu ndi "PP" pansi pa katatu zimasonyeza pulasitiki. Chogulitsacho chimapangidwa ndi zinthu za polypropylene (PP). Zinthuzo ndi zotetezeka komanso zopanda poizoni. Chofunika kwambiri, zimakhala ndi kukana kutentha kwambiri komanso magwiridwe antchito okhazikika. Ndi zinthu zapulasitiki zomwe zitha kuyikidwa mu uvuni wa microwave
Pali mitundu 7 ya zizindikiro zolembera zinthu zapulasitiki. Pakati pa mitundu 7, pali nambala 5 yokha, yomwe ndi yokhayo yomwe ingatenthedwe mu uvuni wa microwave. Ndipo pa mbale zapadera zagalasi za microwave zokhala ndi zivindikiro ndi mbale za ceramic zokhala ndi zivindikiro, chizindikiro cha zinthu za polypropylene PP chiyeneranso kulembedwa.
Manambalawa amayambira pa 1 mpaka 7, omwe akuyimira mitundu yosiyanasiyana ya mapulasitiki, ndipo mabotolo athu amchere, madzi a zipatso, soda yokhala ndi carbonated ndi mabotolo ena a zakumwa omwe amagwiritsidwa ntchito kutentha kwa chipinda amagwiritsa ntchito "1", ndiko kuti, PET, yomwe ili ndi pulasitiki wabwino, yowonekera bwino, komanso yolimba kutentha. N'zosavuta kuwononga ndikutulutsa zinthu zovulaza zikapitirira 70°C.
“Nambala 2″ HDPE nthawi zambiri imagwiritsidwa ntchito m'mabotolo a zimbudzi, zomwe ndi zosavuta kubereketsa mabakiteriya ndipo sizoyenera kugwiritsidwa ntchito kwa nthawi yayitali.
“3″ ndi PVC yodziwika bwino kwambiri, yokhala ndi kukana kutentha kwakukulu kwa 81°C.
“Nambala 4″ LDPE nthawi zambiri imagwiritsidwa ntchito pokulunga pulasitiki, ndipo kukana kwake kutentha sikolimba. Nthawi zambiri imasungunuka pa 110°C, kotero filimuyo iyenera kuchotsedwa potenthetsera chakudya.
Zipangizo za PP za “5″ ndi pulasitiki yoyenerera chakudya, chifukwa chake ndi chakuti zimatha kupangidwa mwachindunji popanda kuwonjezera zowonjezera zilizonse zovulaza, ndipo zimatha kupirira kutentha kwambiri kwa 140°C. Zimagwiritsidwa ntchito makamaka pa uvuni wa microwave. Mabotolo ambiri a ana ndi mabokosi otenthetsera chakudya chamadzulo amapangidwa ndi izi.
Tiyenera kudziwa kuti mabokosi ena a chakudya chama microwave, bokosilo limapangidwa ndi nambala 5 PP, koma chivundikiro cha bokosilo chimapangidwa ndi nambala 1 PE kapena PS (malangizo onse azinthu adzafotokoza), kotero silingayikidwe mu uvuni wa microwave pamodzi ndi bokosilo.
“6″ PS ndiye chinthu chachikulu chopangira zinthu zophikidwa ndi thovu. Sikoyenera kugwiritsa ntchito asidi wamphamvu ndi alkali, ndipo sichingatenthedwe mu uvuni wa microwave.
Pulasitiki ya "7″ imaphatikizapo mapulasitiki ena kupatula 1-6.
Mwachitsanzo, anthu ena amakonda kugwiritsa ntchito mabotolo amadzi olimba kwambiri. Kale, nthawi zambiri ankapangidwa ndi pulasitiki. Chomwe chatsutsidwa ndichakuti chili ndi chinthu chothandiza cha bisphenol A, chomwe chimasokoneza endocrine ndipo chimatulutsidwa mosavuta pamwamba pa 100°C. Makampani ena odziwika bwino agwiritsa ntchito mitundu yatsopano ya mapulasitiki ena kuti apange makapu amadzi, ndipo aliyense ayenera kuwasamala.
Chikwama cha chakudya chowiritsa chotsukira madzi chosungiramo chakudya cha microwave cha phukusi lozizira la RTE lotentha kwambiri Chikwama cha chakudya nthawi zambiri chimapangidwa ndi PET/RCPP kapena PET /PA/RCPP
Mosiyana ndi matumba ena apulasitiki omwe amapangidwa ndi lamian, Microwavable Pouch imaphatikizidwa ndi Polyester Film yapadera yokutidwa ndi Alumina (AIOx) ngati gawo lake loteteza m'malo mwa gawo lokhazikika la aluminiyamu. Imathandiza kuti thumbalo lizitenthedwa lonse mu microwave pomwe limaletsa kuti magetsi asatuluke. Pokhala ndi mphamvu yapadera yodzipumira yokha, Microwavable Pouch imapereka mwayi kwa ogwiritsa ntchito ake pokonzekera chakudya mwa kuchotsa kufunikira kosiya mipata iliyonse mu thumba potenthetsa chakudya mu microwave.
Matumba oimika omwe amalola makasitomala kudya chakudya chawo mwachindunji popanda chifukwa chotsuka mbale kapena mbale. Matumba a Microwavable ndi otetezeka kusindikiza zithunzi mwamakonda, zomwe zimathandiza makampani kuwonetsa zambiri za mtundu wawo ndi malonda awo.
Chonde khalani omasuka kutumiza mafunso. Tidzakupatsani tsatanetsatane kuti mugwiritse ntchito.
