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.

塑料餐具雖然用起來非常方便，但不僅危害身體，對(duì)環(huán)境的污染也是很嚴(yán)重的，尤其一次性刀叉勺，使用一次之后就扔掉了，不僅沒法二次利用，而且無法工業(yè)降解，小小的刀叉勺可能需要好幾百年才能完全降解，對(duì)環(huán)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.

環(huán)保紙質(zhì)餐盒在一定程度上可以降低降解難度，減少對(duì)環(huán)境的污染，市面上的紙質(zhì)餐盒有牛皮紙餐盒，屬于卡紙工藝，但大多會(huì)有pp淋膜，達(dá)到防水防油的效果，不然餐盒會(huì)出現(xiàn)滲油和滲水的情況。

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.

這一類紙質(zhì)餐盒方便印刷，是先印刷再切成型。甘蔗漿或者小麥秸稈漿做成的紙質(zhì)餐盒，是紙漿模塑工藝壓出來的餐盒，添加了食品級(jí)防水防油劑，這種餐盒不添加pp材質(zhì)，屬于生物全降解，45-90天可以堆肥全降解成有機(jī)質(zhì)。但這種可降解餐盒印刷比較困難，除非把logo刻到模具上，油墨印刷的成本會(huì)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.

目前市面上植物纖維餐具中的防油劑大都是含氟的，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，目前比較好的替代方案是覆膜，PBAT是目前紙漿模塑環(huán)保餐具中應(yīng)用范圍更廣、使用更多的復(fù)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.

覆膜后的產(chǎn)品可以更好的保溫，減少溫度通過模塑產(chǎn)品的氣孔散熱，同時(shí)可以減少米飯、水餃等食物的粘粘，很大程度上可以減少防水劑和防油劑的使用。

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.
