泡沫包裝箱也稱為多孔塑料，以樹脂為主要原料制成，內部具有無數空隙，結構形似顆顆爆米花結合而成。一般有硬質、軟質兩種，形狀依據模具而定，一般為白色，具有質輕、防水、隔熱、減震等共同特性，特別適于易碎或液體類物品的包裝，由于導熱系數低也用于新鮮蔬果的保鮮。
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.
其實蔬菜的包裝也有藏不少秘密，不是隨便找個東西把蔬菜裝起來就可以的，而且結合品種的特性，通過行業中人多年的總結和積累而形成的，它其實也在不斷的進步和優化當中，每一種包裝的背后都有的作用和意義。
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:
現在市場上的洋蔥是網袋裝的，一代裝30多公斤，包裝很便宜，甚都不是用個算的，而是稱重的。但是也有人用紙箱裝的，紙箱的成本少是網袋的5-8倍以上，如果我們不挑適合的包裝材料，一車貨下來，你光包裝就比別人成本高好幾千元。所以選擇合適的包裝可以讓你控制好成本。
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.運輸---保護產品、方便運輸：
2. Transportation - protect products and facilitate transportation:
蔬菜產品屬易損品，如果要運到市場上銷售，包裝對于大部分蔬菜而言是個必須品，所以蔬菜的包裝首要的作用就是為了保護產品、方便運輸。對于不同的蔬菜而言，包裝的方式也要不一樣，像一些易壓傷易損壞的蔬菜（番茄類、葉菜類等），我們就要用箱裝，像一些適當可以承壓的蔬菜（蘿卜洋蔥等），我們可以選擇袋裝。
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.
泡沫包裝箱可根據需要加工成各種形狀、不同厚度的包裝產品。在負荷較高的情況下，材料通過變形、吸能、分解能量等達到緩沖、減震的作用，同時具有保溫、隔熱的功能。包裝產品一般為白色，根據要求可生產彩色。
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.
