PP ndi polypropylene, PET ndi polyester.Theoretically onse ndi sanali poizoni, koma ponena za kukana ukalamba ndi kukana nyengo, PP ndi oyenera makapu madzi, PP ali wabwino kutentha kukana, akhoza kupirira kutentha kwa madigiri 120, ndi zinthu pulasitiki yekha amene angathe kuikidwa mu microwave.

Mapulogalamu a polypropylene (PP): mbale za microwave, miphika, ndowa zapulasitiki, zipolopolo za thermos, matumba opangidwa ndi nsalu, ndi zina zotero.Microwave tableware angagwiritsidwe ntchito zolembedwa PP pulasitiki mankhwala.Poizoni: wopanda poizoni, wopanda vuto kwa thupi la munthu.Polima amatha kukhala ndi mawonekedwe atatu amitundu itatu: isometric, intergraphic, atactic polypropylene, awiri oyambawo amatha kuyera, omaliza sangathe.Zogulitsa za polypropylene ndizopanga msika wa iso-gauge, malo osungunuka a 164 ~ 170 digiri Celsius, gawo la crystalline la kachulukidwe ka 0,935 magalamu / ma kiyubiki ma centimita, gawo losakhala loyera la 0,851 magalamu / ma kiyubiki centimita.Choyipa chachikulu cha PP ndikuti ndikosavuta kutulutsa komanso kukalamba.Tsopano ndi kuwonjezera kwa antioxidants ndi ultraviolet absorbers kugonjetsa.
Ntchito za Polyester (PET): mabotolo akumwa apulasitiki, mabotolo amankhwala, mabotolo odzikongoletsera, mabotolo amafuta, ndi zipewa zosiyanasiyana zamabotolo, zophimba zotsekera.Makhalidwe: kuwonekera bwino, kosavuta kuthyola, kukhazikika kwamankhwala kwabwino, koyenera kulongedza zinthu zosiyanasiyana zamadzimadzi kapena zolimba.Ili ndi chitetezo chabwino ku cheza cha ultraviolet.Poizoni: wopanda poizoni.Closeup pa mineral water green mabotolo mu yaiwisi ndi mizere
Botolo la pulasitiki la PET ndiye gawo lalikulu lazopangira zakumwa.Udindo waukulu pamakampani onyamula zakumwa ku China uyenera kukhala mabotolo apulasitiki a PET, pakadali pano, palibe zida zapamwamba kapena zabwinoko zomwe zapezeka kuti zilowe m'malo mwa mabotolo apulasitiki a PET. makina omangira pamabotolo a PP ali ndi zabwino zowonekera, zolimba, zosagwira kutentha, ndipo mtengo wake ndiwotsika.

Mabotolo apulasitiki a PP okhala ndi kukana kutentha kwabwino, mawonekedwe a botolo owoneka bwino, chitetezo, ukhondo ndi zomwe zili mkati mwa kukoma kwa kusungitsa kutsika, mtengo wake ndi wotsika mtengo kuposa PET, PS, PE ndi zida zina. PP mabotolo apulasitiki pamsika wazonyamula zakumwa pakugwiritsa ntchito sikelo yakhala ikuyandikira pang'onopang'ono mabotolo a PET, ma resin osinthidwa, owonjezera ma permeability, ndi luso lamakina ndi zida nthawi ndi nthawi kuti chitukuko cha zotengera za PP zitha m'malo mwa galasi, zotengera za PET ndi PVC, msika ukukula.

.Banja laling'ono likuwotcha ndi aperitif ku cafe yakunja.Italy.
Zida za PP ndi PET zili ndi ubwino wawo ndi makhalidwe awo, palibe zabwino kapena zoipa mtheradi, makamaka zimadalira zosowa za munthu payekha komanso kugwiritsa ntchito zomwe zikuchitika kuti asankhe, ngati nthawi zambiri amagwiritsidwa ntchito pa kutentha kwakukulu, mukhoza kusankha zinthu za PP.Zomwe zili pamwambazi ndikuwunika kwa PPmakapu apulasitikindi makapu apulasitiki a PET, ndikukhulupirira atha kukuthandizani.
