What are the raw materials of degradable tableware?


Conventional lunch boxes generally follow the ratio of 70%-90% sugarcane fiber + 10%-30% bamboo pulp fiber. Different tableware will also adjust different fiber ratios according to the product shape, angle, hardness, and stiffness. Of course, plant fibers such as wheat straw, wheat straw, and reed will also be added as needed. It is all made of plant fiber, no chemical materials such as PP and PET are added.


How does the disposable cutlery achieve the effect of waterproof and oil-proof?


Certain food-grade additives are added to the pulp molded lunch box, general water-repellent agent: 1.0%-2.5%, oil-repellent agent: 0.5%-0.8%, so as to achieve the effect of waterproof and oil-proof. When testing, it is generally water at 100°C and oil at 120°C, and the test time is 30 minutes; for special products, the oil temperature and test time can be extended.


Do biodegradable disposable tableware products contain fluoride?


At present, most of the oil repellents in plant fiber tableware on the market are fluorine-containing, and just water-proof tableware is fluorine-free.


If biodegradable one time use cutlery is required to be fluorine-free and water-proof and oil-proof, a better alternative is film coating. PBAT is currently the most widely used composite material in pulp molded environmentally friendly tableware.


The coated product can keep heat better, heat dissipation can be achieved through the stomata of molded products, thereby reducing the temperature. At the same time, it can reduce the stickiness of food such as rice and dumplings, which can greatly reduce the use of water-repellent and oil-repellent agents.


How long can disposable tableware be completely degraded?


Without any industrial decomposer, it takes about 45-90 days for the pulp-molded environmentally friendly tableware to completely decompose in the natural state of the landfill. No harmful ingredients are produced, and it will not cause harm to terrestrial organisms, marine corals or marine organisms.


After degradation, 82% of the ingredients are organic matter, which can be used as fertilizer for land use. Truly take from the nature and return to nature.


Can disposable tableware be heated in microwave and refrigerated in refrigerator?


The biodegradable one time use cutlery can be heated by microwave and baked in the oven without harmful chemicals in the product. The maximum temperature can reach 220°C.


In addition, it can support refrigerator freezing and refrigeration, which can reach minus 18°C.


Can the biodegradable one time use cutlery be printed with logo?


Certainly, mostly on the circumference of the lunch box, such as the bottom or top. Need to use curved printing. According to the printing equipment, it is divided into screen printing, pad printing and laser laser printing (code printing).


Are the white biodegradable one time use cutlery bleached?


Unbleached plant fiber pulp contains a small amount of lignin and colored impurities, so it is yellow and the fiber is hard. Semi-bleached pulp contains a lot of polypentose, which is light yellow in color, commonly known as natural color. The fiber of bleached pulp is white, pure and soft, but due to bleaching treatment, the fiber strength is lower than that of unbleached pulp.


Bleaching agents generally use hydrogen peroxide for bleaching, not chlorine bleaching!
