"Stone paper" can be used by researchers to evenly integrate high concentration ceramic material particles into fibers for food packaging

[ppzhan Abstract] Stone paper has once again successfully attracted the public's attention, because in addition to its previous functions to measure elongation accurately, it has once again become the coat of food

Stone paper, which attracted the attention of the representatives of the two sessions in 2010, has recently found new uses. Stone paper can be widely used in food packaging, food shopping bags and catering supplies.

in the production process of stone papermaking, no trees are cut down, no water is used, no sewage and toxic and harmful substances are discharged. Stone paper series products have the characteristics of safety, environmental protection, non-toxic, waterproof, anti fog, anti oil, anti insect, tear resistance, folding resistance, affordable price and so on

according to the person in charge of earthguard (Tianjin) environmental protection new materials Co., Ltd., stone paper, after being used for office and printing, has also developed and produced paper and plastic bags related to food. 4.
