Melamine tableware ke mofuta oa tableware o nang le likotsi tsa polokeho.Hobane metsoako e sa tšoanelehe, melamine tableware e tla kopana le mathata.Ebile, tableware ea melamine e sebetsa ho "Sanitary Standard for Melamine-Formaldehyde Forming Products for Food Containers and Packaging Materials".Ke lisebelisoa life tse lokelang ho ngoloa ho melamine tableware?
"Litekanyetso tsa Bohloeki bakeng sa Tšebeliso ea Li-additives bakeng sa Lijana tsa Lijo le Lisebelisoa tsa Packaging" li ne li kenngoe tšebetsong ka June 1 2016. E hlalosa horelintho tse tala melamine-formaldehyde resin(e leng, melamine resin) ha ea lokela ho lokolla lintho tse kotsi ho bophelo bo botle tlas'a maemo a khothalletsoang a tšebeliso;ha ho fumanoa matšoao a bohloeki ba 'mele le lik'hemik'hale, Boikemisetso ba palo ea ho falla ha melamine monomer bo ile ba eketseha.
Bakeng sa ho ngola melamine tableware, thethepa e tala ea tablewareho hlokahala ka ho hlaka ka lekhetlo la pele, 'me "sekhahla sa lijo" le "ho futhumatsa ka ontong ea microwave e thibetsoeng" li lokela ho tsebisoa.Sephutheloana sa ka ntle se hlokahala ka ho hlaka hore se tšoauoa ka "mophato oa lijo" mme moetsi, lebitso la sehlahisoa, maemo a ts'ebeliso, mefuta ea lisebelisoa, joalo-joalo.
