可降解餐具使用中经常有的几个疑问

可降解餐具使用的原料成分及各自的配比有哪些？

What are the ingredients of degradable tableware and their respective proportions?

常规餐盒一般以70%-90%的甘蔗纤维和10%-30%的竹浆纤维为主。不同的餐具也会根据产品的形状、角度、硬度和刚度来调整不同的纤维比例。当然，麦秸、麦秸、芦苇等植物纤维也会根据需要添加。全部由植物纤维制成，不添加PP、PET等化学材料。

Conventional lunch boxes are generally 70%-90% sugarcane fiber and 10%-30% bamboo pulp fiber. Different tableware will also adjust different fiber proportion according to the shape, angle, hardness and stiffness of the product. Of course, wheat straw, wheat straw, reed and other plant fibers will also be added as needed. It is all made of plant fiber without adding PP, pet and other chemical materials.

可降解颗粒一次性餐具产品含氟吗？

Does degradable granule disposable tableware product contain fluorine?

目前市面上的植物纤维餐具中的拒油剂大部分都是含氟的，防水不防油的餐具都是无氟的。如果要求可降解餐具无氟防水防油，目前比较好的替代方案是覆膜。PBAT是一种应用广泛的复合材料，广泛用于成型环保餐具。覆膜产品可以保持更好的保温性，减少通过成型品的气孔散发的热量，同时降低米饭、饺子等食物的粘性，可以大大减少防水剂和油的使用驱虫剂。

At present, most of the oil repellents in the vegetable fiber tableware on the market are fluorine-containing, and the tableware that is waterproof but not oil-proof is fluorine-free. If the degradable tableware is required to be fluorine free, waterproof and oil-proof, at present, the better alternative is film coating. PBAT is a widely used composite material, which is widely used to form environmental friendly tableware. Film coated products can maintain better thermal insulation, reduce the heat emitted through the pores of molded products, reduce the viscosity of rice, dumplings and other foods, and greatly reduce the use of waterproof agents and oil insect repellents.

环保餐具要多久才能完全降解？

How long will it take for environmental friendly tableware to completely degrade?

在没有任何工业分解机的情况下，成型的环保餐具在垃圾填埋场的自然状态下大约需要45-90天才能完全分解。不产生有害成分，不会对陆生生物、海洋珊瑚或海洋生物造成伤害。降解后，82%的成分为有机物，可作土地肥料。

In the absence of any industrial decomposition machine, it takes about 45-90 days to completely decompose the formed environmental friendly tableware in the natural state of the landfill. It does not produce harmful ingredients and will not cause damage to terrestrial organisms, marine corals or marine organisms. After degradation, 82% of the components are organic matter, which can be used as land fertilizer.

一次性餐具可以微波炉冷藏吗？它可以达到多少温度？

Can disposable tableware be refrigerated in a microwave oven? What temperature can it reach?

可降解饭盒可微波炉、烤箱烘烤，不含有害化学物质，耐高温可达220℃。可支持冰箱冷冻冷藏，冷冻可达-18℃。

The degradable lunch box can be baked in microwave oven and oven. It does not contain harmful chemicals and can withstand high temperature up to 220 ℃. It can support refrigerator refrigeration, and the freezing can reach -18 ℃.

可生物降解的饭盒可以打印标志吗？

Can biodegradable lunch boxes print labels?

可以打印徽标。印刷品多为饭盒产品的周边、底部或顶部。杯子、碗等产品大多印在产品的外面，需要曲面印刷。按印刷设备分为丝网印刷、移印和激光激光印刷（喷墨印刷）。印刷产品会相应增加产品成本。

You can print the logo. Most of the printed materials are the periphery, bottom or top of the lunch box products. Cups, bowls and other products are mostly printed on the outside of the product and need curved surface printing. According to the printing equipment, it can be divided into screen printing, pad printing and laser printing (inkjet printing). Printing products will increase the product cost accordingly.

白色可降解颗粒餐具所用的原料是否经过漂白处理？用什么漂白剂？

Are the raw materials used in white degradable granule tableware bleached? With what bleach?

未漂白的植物纤维呈黄色且坚硬，因为它们含有少量的木质素和有色杂质。半漂白浆中含有大量戊糖多糖，颜色呈淡黄色，俗称本色。漂白纸浆的纤维洁白、纯洁、柔软，但由于经过漂白处理，纤维强度低于未漂白纸浆。漂白剂一般是用双氧水漂白，而不是氯漂白剂！

Unbleached plant fibers are yellow and hard because they contain small amounts of lignin and colored impurities. Semi bleached pulp contains a large number of pentose polysaccharides, which are light yellow in color, commonly known as natural color. The fiber of bleached pulp is white, pure and soft, but the fiber strength of bleached pulp is lower than that of unbleached pulp. Bleach is usually bleached with hydrogen peroxide, not chlorine bleach!
