有的塑料餐具含有聚苯乙烯,在60摄氏度高温下会释放出致癌物质。人如果长期使用,摄入过量的致癌物质苯,身体可能会受损。

Some plastic tableware contains polystyrene, which will release carcinogens at a high temperature of 60 ℃. If people use it for a long time and ingest too much carcinogen benzene, their bodies may be damaged.
塑料餐具虽然用起来非常方便,但不仅危害身体,对环境的污染也是很严重的,尤其一次性刀叉勺,使用一次之后就扔掉了,不仅没法二次利用,而且无法工业降解,小小的刀叉勺可能需要好几百年才能完全降解,对环境的污染是不可估量的。
Although plastic tableware is very convenient to use, it not only does harm to the body, but also causes serious environmental pollution. In particular, disposable knives, forks and spoons are thrown away after being used once, which can not be reused and can not be degraded industrially. Small knives, forks and spoons may take hundreds of years to be completely degraded, and the pollution to the environment is immeasurable.
环保纸质餐盒在一定程度上可以降低降解难度,减少对环境的污染,市面上的纸质餐盒有牛皮纸餐盒,属于卡纸工艺,但大多会有pp淋膜,达到防水防油的效果,不然餐盒会出现渗油和渗水的情况。
Environmentally friendly paper lunch boxes can reduce the difficulty of degradation and reduce the pollution to the environment to a certain extent. The paper lunch boxes on the market include kraft paper lunch boxes, which belong to the paper jam process, but most of them will have PP film to achieve the effect of waterproof and oil prevention. Otherwise, the lunch boxes will have oil and water seepage.

这一类纸质餐盒方便印刷,是先印刷再切成型。甘蔗浆或者小麦秸秆浆做成的纸质餐盒,是纸浆模塑工艺压出来的餐盒,添加了食品级防水防油剂,这种餐盒不添加pp材质,属于生物全降解,45-90天可以堆肥全降解成有机质。但这种可降解餐盒印刷比较困难,除非把logo刻到模具上,油墨印刷的成本会很高。
This kind of paper lunch box is convenient for printing. It is printed first and then cut into shape. The paper lunch box made of sugarcane pulp or wheat straw pulp is a lunch box pressed out by the pulp molding process. It is added with food grade waterproof and oil proof agent. This kind of lunch box does not add PP material. It is fully biodegradable and can be composted and fully degraded into organic matter in 45-90 days. However, the printing of this degradable lunch box is difficult. Unless the logo is engraved on the mold, the cost of ink printing will be very high.
目前市面上植物纤维餐具中的防油剂大都是含氟的,防水不防油的餐具是不含氟的。
At present, most of the oil proofing agents in the vegetable fiber tableware on the market are fluorine-containing, and the tableware that is waterproof but not oil-proof is fluorine-free.
如果要求可降解餐具不含氟且防水防油,目前比较好的替代方案是覆膜,PBAT是目前纸浆模塑环保餐具中应用范围更广、使用更多的复合材料。
If degradable tableware is required to be fluorine-free, waterproof and oil-proof, at present, the better alternative is film coating. PBAT is the composite material with the widest application range and the most use in pulp molded environmental protection tableware.
覆膜后的产品可以更好的保温,减少温度通过模塑产品的气孔散热,同时可以减少米饭、水饺等食物的粘粘,很大程度上可以减少防水剂和防油剂的使用。
The coated products can better keep warm, reduce the temperature and dissipate heat through the pores of molded products. At the same time, it can reduce the stickiness of rice, dumplings and other foods, and greatly reduce the use of waterproof and oil proof agents.
