一次性紙餐盒是以紙為基材，表面覆蓋有石蠟、聚乙烯涂層等用于食品包裝或盛裝冷熱飲料和冷熱食品的容器，由于采用紙材料制作，因而既可以回收使用，又可以通過掩埋或燃燒等方式處理，而不至于造成嚴(yán)重的環(huán)境污染，具有較高的環(huán)保價(jià)值。那么紙餐盒應(yīng)該如何選購(gòu)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?

一是看材質(zhì)。有的紙碗看起來比較厚實(shí)，表面用食品級(jí)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(zhì)。

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.

二是聞味道。在紙杯、紙碗倒入熱水時(shí)如果產(chǎn)生怪味，也不要再使用。這可能是因?yàn)樵偕垡蚁┰谠偌庸み^程中產(chǎn)生裂解變化，許多化合物遇到高溫?fù)]發(fā)出來，易向水中遷移。

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.

三是看標(biāo)志。目前，國(guó)家已對(duì)部分紙制品實(shí)施生產(chǎn)許可證管理，產(chǎn)品或包裝、說明書上應(yīng)標(biāo)注QS標(biāo)志和編號(hào)，產(chǎn)品使用說明書或標(biāo)簽上應(yīng)注明產(chǎn)品使用方法、使用注意事項(xiàng)、用途、使用環(huán)境、使用溫度等內(nèi)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.

四是看看顏色。在購(gòu)買紙杯時(shí)，應(yīng)選擇印刷顏色較淺的產(chǎn)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(zhì)，建議不要使用。同時(shí)，應(yīng)區(qū)分冷飲杯與熱飲杯。

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(cè)面和底部的封口相對(duì)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(huì)滲漏，造成燙傷等危害。因此，冷飲紙杯不能用來裝熱飲。

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

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.

市場(chǎng)上的紙質(zhì)餐盒和紙杯優(yōu)劣不一，在這些五花八門的紙餐盒中，應(yīng)該如何選購(gòu)呢?以上就是為您講解的這個(gè)問題的內(nèi)容了，希望能夠給您好的幫助，更多事項(xiàng)就來我們網(wǎng)站http://www.mingmingda.com咨詢！
