剛剛上幼兒園的時候，老師都會發給我們每人一個書包，還跟小伙伴們都一模一樣的書包，讓我們興奮了好久，回家都不肯摘下來。幼兒園的書包是幼兒園不可缺少的開銷，是每個孩子上學的用品。因為孩子處于長身體的階段，孩子的書包我們都會采用雙肩書包。幼兒園在采購雙肩書包的時候也是非常重要的環節，我們一起來看看雙肩書包選購要注意哪些方面？
When we just went to kindergarten, the teacher would give each of us a schoolbag, which was the same as the schoolbags of our friends. We were excited for a long time and refused to take it off at home. The schoolbag of the kindergarten is an indispensable expense of the kindergarten, and is the supplies for each child to go to school. Because the child is in the stage of growing up, we all use backpacks for children's schoolbags. The kindergarten is also a very important link when purchasing backpacks. Let's take a look at what should be paid attention to when purchasing backpacks?
一 幼兒園書包的材質尺寸選購

幼兒園書包定制時要注意材質問題，劣質的書包原材料一般都含有大量毒性，書包使用的顏料多樣，也有可能是用了膠印工藝，使用了很多的油墨和化學藥水，一般都會散發出很濃的氣味，很容易對孩子的肺及眼睛造成傷害，這也經常是孩子家長說背包氣味很大的原因。兒童的免疫力本身就沒有大人好，所以在給孩子挑選書包材質一定要選擇材質好的書包，一般可選購定制PVC、布料等材質，在顏色與外形上可以豐富多彩，在材質上輕便、無味且不易變形。
When customizing schoolbags in kindergartens, attention should be paid to the material quality. Poor schoolbag raw materials generally contain a lot of toxicity. Schoolbags use a variety of pigments. It may also be that offset printing technology is used, and a lot of ink and chemical liquid are used. Generally, they will emit a strong smell, which is easy to cause damage to children's lungs and eyes. This is often the reason why parents say that backpacks smell great. Children's immunity is not as good as adults. Therefore, when choosing schoolbag materials for children, we must choose schoolbags with good materials. Generally, we can choose customized PVC, cloth and other materials. They can be colorful in color and shape. The materials are light, tasteless and not easy to deform.
因為是幼兒園書包，所以在尺寸上我們要選擇小書包，才能貼合孩子們的身材。一般來說，選擇能夠裝下孩子書本和文具的小背包就好，書包不可以比孩子的身體還寬，背在身上的書包底部不可以低于孩子腰部10厘米。
Because it is a kindergarten schoolbag, we should choose a small schoolbag in size to fit the children's body. Generally speaking, it is good to choose a small backpack that can hold children's books and stationery. The backpack cannot be wider than the child's body, and the bottom of the backpack carried on the body cannot be lower than the child's waist by 10 cm.
