1. What are the raw materials used in the disposable degradable lunch box and their respective ratios?
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.
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%, to achieve the effect of waterproof and oil-proof. The test is generally 100°C water, 120°C oil, and the test time is 30 minutes; special requirements can be done to extend the oil temperature and test time.
3. Does the degradable disposable tableware products contain fluorine?
At present, most of the oil repellents in plant fiber tableware on the market are fluorine-containing, and water- and oil-proof tableware is fluorine-free.
If biodegradable tableware is required to be fluorine-free and water- and oil-proof, the current better alternative is film coating. PBAT is currently the most widely used and most used composite material in pulp molded environmentally friendly tableware.
Coated products can better retain heat and reduce heat dissipation through the pores of the moulded product, while reducing the stickiness of foods such as rice and dumplings and, to a large extent, reducing the use of water and oil repellents.
4. How long can the environmentally friendly pulp 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, using natural materials and returning to nature.
5. Can disposable paper pulp tableware be heated in microwave and refrigerated in refrigerator? How much temperature can it reach?
The biodegradable pulp lunch box can be heated by microwave and baked in the oven without any harmful chemicals in the product. The maximum temperature can reach 220°C. It can support refrigerator freezing, freezing up to minus 18 ℃.
6. What type of product quality inspection standards does the molded pulp lunch box meet?
The biodegradable plant fiber lunch box meets the national "Pulp Molded Tableware" quality inspection standards, the United States Food and Drug Administration (FDA), the German New Food and Diet Products Act (LFGB), and other international standardized inspection standards.
Logo can be printed. The printed products are mostly the circumference, bottom or top of the lunch box product. Products such as cups and bowls are mostly printed on the outside of the product, and curved printing is required. According to the printing equipment, it is divided into screen printing, pad printing and laser laser printing (code printing).
Printing products will increase product costs accordingly.
8. Have the raw materials used in the white biodegradable lunch box been bleached? What bleach is used?
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 to bleach, not chlorine bleach!
