一次性纸餐盒是以纸为基材，表面覆盖有石蜡、聚乙烯涂层等用于食品包装或盛装冷热饮料和冷热食品的容器，由于采用纸材料制作，因而既可以回收使用，又可以通过掩埋或燃烧等方式处理，而不至于造成严重的环境污染，具有较高的环保价值。那么纸餐盒应该如何选购呢？

A disposable paper lunch box is a container made of paper as the substrate, covered with paraffin, polyethylene coating, and other materials for food packaging or containing cold and hot beverages and food. Due to the use of paper materials, it can be recycled and treated through burial or combustion, without causing serious environmental pollution, and has high environmental value. So how should I choose a paper lunch box?

一是看材质。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。

One is to look at the material. Some paper bowls look relatively thick, with a surface made of food grade raw paper, while the middle layer is made of recycled paper, cardboard, etc. It is recommended to tear them open to see if the broken surface is yellow or contains a lot of impurities.

二是闻味道。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。

The second is to smell the taste. If there is a strange smell when pouring hot water into a paper cup or bowl, do not use it again. This may be because regenerated polyethylene undergoes cracking changes during the reprocessing process, causing many compounds to evaporate at high temperatures and easily migrate into water.

三是看标志。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。

The third is to look at the signs. At present, the country has implemented production license management for some paper products. The QS logo and number should be marked on the product or packaging, and the product manual or label should indicate the product's usage method, usage precautions, purpose, usage environment, and temperature.

四是看看颜色。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。

Fourth, look at the colors. When purchasing paper cups, products with lighter printing colors should be chosen. However, if the color of the paper product is too white, it may be due to the addition of a large amount of fluorescent whitening agent or impurities, and it is recommended not to use it. At the same time, a distinction should be made between cold drink cups and hot drink cups.

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。

Cold drink cups are mainly used to hold frozen drinks, carbonated beverages, etc. Compared to hot drink paper cups, the seals on the sides and bottom of the paper cups cannot withstand high temperatures. If hot water is poured into them, under high temperature conditions, cold drink paper cups may leak, causing burns and other hazards. Therefore, cold drink paper cups cannot be used to hold hot drinks.

五是要看挺度。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。

Fifth, it depends on the stiffness. Good paper cups or bowls are very hard and have resilience, while inferior paper cups and bowls often become soft after being pinched and have no rebound performance. It is recommended to pinch them when choosing, and try to choose paper cups and bowls with a hard body.
