裝面包的紙袋，快餐店盛放薯條、雞翅的紙盒，家里招待客人用的一次性紙杯等，生活中，隨處可見紙制食品包裝的身影。不過，這些五花八門的紙質商品質量究竟如何？下面小編分別對一次性紙杯和一次性紙餐盒產品進行了使用分析。

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.

市場上的紙質餐盒和紙杯優(yōu)劣不一，消費者又該如何選購呢？

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

一是看顏色。在購買紙杯時，應選擇印刷顏色較淺的產品，但如果紙制品顏色過白,可能是加入了大量熒光增白劑或者其中含有雜質，建議不要使用。同時，應區(qū)分冷飲杯與熱飲杯。

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.

冷飲杯主要用于裝冷凍飲品、碳酸飲料等，和熱飲紙杯相比，冷飲紙杯的紙杯側面和底部的封口相對不能耐受較高的溫度，如果向其中灌注熱水，在溫度比較高的條件下，冷飲紙杯可能會滲漏，造成燙傷等危害。因此，冷飲紙杯不能用來裝熱飲。

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。好的紙杯或紙碗很硬，有回彈性，劣質的紙杯和紙碗往往捏了以后很軟，沒有回彈性能，建議選購的時候可以捏一捏，盡量選購杯身硬挺的紙杯和紙碗。

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.

三是看材質。有的紙碗看起來比較厚實，表面用食品級的原紙，中間層卻用回料紙、箱板紙等，建議撕開看一看其斷層面是否為黃色或含較多雜質。

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.

四是聞味道。在紙杯、紙碗倒入熱水時如果產生怪味，也不要再使用。這可能是因為再生聚乙烯在再加工過程中產生裂解變化，許多化合物遇到高溫揮發(fā)出來，易向水中遷移。

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.

五是看標志。目前，國家已對部分紙制品實施生產許可證管理，產品或包裝、說明書上應標注QS標志和編號，產品使用說明書或標簽上應注明產品使用方法、使用注意事項、用途、使用環(huán)境、使用溫度等內容。

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.
