Q1: What are the raw materials used in the disposable degradable food box and their respective ratios?

A: Conventional food 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. Certainly, plant fibers such as wheat straw and reed will also be added as needed. It is all made of plant fiber and doesn’t add chemical materials such as PP and PET .

Q2: How does the pulp molding disposable food box achieve the effect of waterproof and oil-proof?

A: The pulp molding food box will add certain additives , general waterproofing agent: 1.0%-2.5%, Oil repellent: 0.5%-0.8%, to achieve the effect of waterproof and oil-proof. The test is generally water at 100°C and oil at 120°C, and the test time is 30 minutes; special requirements can be done to extend the oil temperature and test time.

Q3: Do degradable disposable tableware products contain fluorine?

A: At present, most of the oil repellents contain fluorine in plant fiber tableware on the market , and water- and oil-proof tableware does not contain fluorine. If biodegradable tableware is required to be fluorine-free and water- and oil-proof, a better alternative is film coating. PBAT is currently the most widely used and most used composite material in pulp molding eco-friendly tableware. The coated product can keep heat better, reduce the heat dissipation through the pores of the molded product, and reduce the stickiness of food such as rice and dumplings, which can greatly reduce the use of water-repellent and oil-repellent agents.

Q4: How long can the eco-friendly pulp molding tableware be completely degraded? 

A: Without any industrial decomposer, it takes about 45-90 days for the pulp molding eco-friendly tableware to completely decompose in the nature. No harmful ingredients are produced, and it will not harm to terrestrial creatures, ocean coral and marine life. After degradation, 82% of the ingredients are organic substances, which can be used as fertilizers. Use to nature, return to nature.

Q5: Can disposable pulp molding tableware be heated by microwave and refrigerated in refrigerator? How much temperature can it reach?

A: The biodegradable pulp molding food box can be heated by microwave and baked in the oven without harmful chemicals . The maximum temperature can reach 220°C. It can support refrigerator freezing, freezing up to minus 18 ℃.

Q6: What type of product quality inspection standards does the pulp molding tableware meet?

Q7: Can the logo be printed on the biodegradable tableware?  

A: Logo can be printed. The printed products are mostly the circle , bottom or top of the food box. Products such as cups and bowls are mostly printed on the outside of the product with curved printing. According to the printer, it is divided into screen printing, pad printing and laser printing (code printing). Printing products will increase costs accordingly.

Q8: Have the raw materials used in the white degradable tableware been bleached? What bleach is used? 

A: 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, 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 generally use hydrogen peroxide for bleaching, not chlorine bleaching!
