装面包的纸袋，快餐店盛放薯条、鸡翅的纸盒，家里招待客人用的一次性纸杯等，生活中，随处可见纸制食品包装的身影。不过，这些五花八门的纸质商品质量究竟如何？下面小编分别对一次性纸杯和一次性纸餐盒产品进行了使用分析。

Paper bags for bread, paper boxes for French fries and chicken wings in fast food restaurants, disposable paper cups for guests at home, etc. paper food packaging can be seen everywhere in life. However, what is the quality of these various paper products? The following editors have analyzed the use of disposable paper cups and disposable paper lunch boxes.

市场上的纸质餐盒和纸杯优劣不一，消费者又该如何选购呢？

The paper lunch boxes and paper cups in the market are of different quality. How should consumers choose?

一是看颜色。在购买纸杯时，应选择印刷颜色较浅的产品，但如果纸制品颜色过白,可能是加入了大量荧光增白剂或者其中含有杂质，建议不要使用。同时，应区分冷饮杯与热饮杯。

First, look at the color. When purchasing paper cups, products with lighter printing color should be selected. However, if the color of paper products is too white, it may be that a large amount of fluorescent whitening agent is added or there are impurities in it, and it is recommended not to use them. At the same time, it is necessary to distinguish between cold drinking cup and hot drinking cup.

冷饮杯主要用于装冷冻饮品、碳酸饮料等，和热饮纸杯相比，冷饮纸杯的纸杯侧面和底部的封口相对不能耐受较高的温度，如果向其中灌注热水，在温度比较高的条件下，冷饮纸杯可能会渗漏，造成烫伤等危害。因此，冷饮纸杯不能用来装热饮。

The cold drink cup is mainly used to hold frozen drinks, carbonated drinks, etc. compared with the hot drink paper cup, the side and bottom seals of the cold drink paper cup are relatively unable to withstand the high temperature. If hot water is poured into the cold drink paper cup, the cold drink paper cup may leak under the condition of high temperature, causing burns and other hazards. Therefore, cold drink paper cups cannot be used to hold hot drinks.

二是要看挺度。好的纸杯或纸碗很硬，有回弹性，劣质的纸杯和纸碗往往捏了以后很软，没有回弹性能，建议选购的时候可以捏一捏，尽量选购杯身硬挺的纸杯和纸碗。

Second, it depends on the stiffness. Good paper cups or paper bowls are hard and resilient. Poor paper cups and paper bowls are often soft after being pinched and have no rebound performance. It is recommended to pinch them when buying them. Try to buy paper cups and paper bowls with stiff bodies.

三是看材质。有的纸碗看起来比较厚实，表面用食品级的原纸，中间层却用回料纸、箱板纸等，建议撕开看一看其断层面是否为黄色或含较多杂质。

Third, look at the material. Some paper bowls look thick. The surface is made of food grade base paper, while the middle layer is made of recycled paper and box board paper. It is suggested to tear them apart to see if the broken surface is yellow or contains more impurities.

四是闻味道。在纸杯、纸碗倒入热水时如果产生怪味，也不要再使用。这可能是因为再生聚乙烯在再加工过程中产生裂解变化，许多化合物遇到高温挥发出来，易向水中迁移。

Fourth, smell. When pouring hot water into paper cups and bowls, if there is a strange smell, do not use it again. This may be due to the cracking change of regenerated polyethylene during reprocessing, and many compounds volatilize at high temperature and are easy to migrate to water.

五是看标志。目前，国家已对部分纸制品实施生产许可证管理，产品或包装、说明书上应标注QS标志和编号，产品使用说明书或标签上应注明产品使用方法、使用注意事项、用途、使用环境、使用温度等内容。

Fifth, look at the signs. At present, the state has implemented the production license management on some paper products. The QS mark and number shall be marked on the products or packages and instructions, and the product use method, precautions for use, purpose, use environment, use temperature and other contents shall be marked on the product use instructions or labels.
