Zida zofala za mafilimu wamba zapulasitiki zimaphatikizaponso PP, pe, ps, etc.
1.
PP ndi dzina lathunthu la polypropylene, lomwe ndi pulasitiki yogwiritsidwa ntchito kwambiri yomwe ilibe zinthu zovulaza ndipo ndi chakudya {- grade. Mabokosi a nkhomaliro a PP ali ndi mawonekedwe a kutentha kwabwino, kuwonekera kwambiri, kulimba mtima, etc.
2. PECTE BODZA BWINO
Pe ndi dzina lathunthu la polyethylene, lomwe ndi chakudya - pulasitiki ya pulasitiki. Mabokosi a nkhomaliro ali ndi mawonekedwe a kusinthasintha kwatsopano, kulimba mtima kwamphamvu, mtengo wotsika, ndi zina zambiri, ndipo ndizakudya zophika.
3. Bokosi la FLOVER BATT
PS ndi dzina lathunthu la polystyrene, lomwe ndi pulasitiki yokhala ndi ukwati wabwino, wouma komanso wolemera. Mabokosi a FLORICT PCTOTES ndi oyenera mabokosi odyera komanso osankhidwa, koma osavomerezeka kuti awateteze mu microwave kuti asapange zinthu zovulaza.
Kuphatikiza pa zinthu zomwe zili pamwambapa, pali zinthu zina zatsopano zodyeramo chakudya, monga zida zam'madzi, zida zowonongeka, ndi zina zowonjezera, etc.
4. Mabokosi atsopano achitetezo
Zinthu zamagetsi ndi zinthu zopangidwa ndi chowuluka cha chimanga kapena sucrose. Ndi chilengedwe chochezeka komanso chowonekera kwambiri, ndipo ndizoyenera kufupikitsa kwa nthawi yayifupi {1} {1}
Zipangizo zosawonongeka zakhumudwitsa kwambiri chifukwa sizidetsa chilengedwe. Mabokosi achakudya chochepetsedwa amapangidwa makamaka ndi zinthu zachilengedwe monga wowuma ndi fiber ndi zinthu zopangidwa ndi polylactic acid. Amatha kuwola mu zachilengedwe zachilengedwe ndikuchepetsa kuwonongeka kwa chilengedwe.
