泡沫包装箱也称为多孔塑料，以树脂为主要原料制成，内部具有无数空隙，结构形似颗颗爆米花结合而成。一般有硬质、软质两种，形状依据模具而定，一般为白色，具有质轻、防水、隔热、减震等共同特性，特别适于易碎或液体类物品的包装，由于导热系数低也用于新鲜蔬果的保鲜。
The foam packaging box is also called porous plastic, made of resin as the main raw material, and has numerous gaps inside, and the structure is shaped like popcorn. It is generally hard and soft. Its shape depends on the mold. It is generally white. It has the common characteristics of light weight, waterproof, heat insulation and shock absorption. It is especially suitable for the packaging of fragile or liquid goods. It is also used for the preservation of fresh fruits and vegetables due to its low thermal conductivity.
其实蔬菜的包装也有藏不少秘密，不是随便找个东西把蔬菜装起来就可以的，而且结合品种的特性，通过行业中人多年的总结和积累而形成的，它其实也在不断的进步和优化当中，每一种包装的背后都有的作用和意义。
In fact, there are many secrets in the packaging of vegetables. It is not just to find something to pack vegetables. Moreover, combined with the characteristics of varieties, it is formed through the summary and accumulation of people in the industry for many years. In fact, it is also constantly improving and optimizing. There are functions and significance behind each kind of packaging.
1.成本---因菜而定，降低成本：
1. Cost - depending on the dishes, reduce the cost:
现在市场上的洋葱是网袋装的，一代装30多公斤，包装很便宜，甚都不是用个算的，而是称重的。但是也有人用纸箱装的，纸箱的成本少是网袋的5-8倍以上，如果我们不挑适合的包装材料，一车货下来，你光包装就比别人成本高好几千元。所以选择合适的包装可以让你控制好成本。
Now the onions on the market are packed in net bags, with a generation of more than 30 kg. The packaging is very cheap. They are not even calculated, but weighed. However, some people pack them in cartons. The cost of cartons is at least 5-8 times that of net bags. If we don't choose suitable packaging materials, you will cost thousands of yuan more than others for packaging alone. So choosing the right packaging can let you control the cost.
2.运输---保护产品、方便运输：
2. Transportation - protect products and facilitate transportation:
蔬菜产品属易损品，如果要运到市场上销售，包装对于大部分蔬菜而言是个必须品，所以蔬菜的包装首要的作用就是为了保护产品、方便运输。对于不同的蔬菜而言，包装的方式也要不一样，像一些易压伤易损坏的蔬菜（番茄类、叶菜类等），我们就要用箱装，像一些适当可以承压的蔬菜（萝卜洋葱等），我们可以选择袋装。
Vegetable products are vulnerable products. If they are to be transported to the market for sale, packaging is a must for most vegetables, so the primary role of vegetable packaging is to protect products and facilitate transportation. For different vegetables, the packaging method is different. For some vegetables that are easy to be crushed and damaged (tomatoes, leafy vegetables, etc.), we need to pack them in boxes. For some vegetables that can bear pressure properly (radishes, onions, etc.), we can choose to pack them in bags.
泡沫包装箱可根据需要加工成各种形状、不同厚度的包装产品。在负荷较高的情况下，材料通过变形、吸能、分解能量等达到缓冲、减震的作用，同时具有保温、隔热的功能。包装产品一般为白色，根据要求可生产彩色。
The foam packing box can be processed into various shapes and different thickness packaging products according to needs. In the case of high load, the material can achieve the functions of cushioning and shock absorption through deformation, energy absorption and energy decomposition, and has the functions of thermal insulation and heat insulation. Packaging products are generally white, and color can be produced according to requirements.
