当前，产品和物资流通是经济活动中重要的组成部分，其以生产工厂为起点，以消费者为终点，包括了商品及包装的运输、中转、装卸、仓储、陈列、销售等环节。当今包装新技术层出不穷，如缓冲防震包装、集合包装、显窃启包装、儿童包装、防伪包装、保鲜包装、真空包装等。作为体现保护产品功能的纸箱缓冲结构，其在纸箱的特征设计中千变万化。本文试就纸板折叠式缓冲包装的结构进行分析。
At present, the circulation of products and materials is an important part of economic activities, which starts from the production factory and ends at the consumer, including the transportation, transit, loading and unloading, storage, display, sales and other links of goods and packaging. Nowadays, new packaging technologies emerge in endlessly, such as cushioning and shockproof packaging, collective packaging, tamper proof packaging, child safety packaging, anti-counterfeiting packaging, fresh-keeping packaging, vacuum packaging and so on. As a kind of carton cushioning structure which can protect the product, it is changeable in the feature design of carton. This paper tries to analyze the structure of paperboard folding cushioning packaging.
缓冲包装方法主要指产品与纸箱之间填满缓冲材料使所有面都被纸板固定，对产品采用保护的办法。它的优点是适合于形状复杂，批量不大的产品包装，并且缓冲材料与产品有较大的接触面积静应力小，并且能够吸收大的冲击能，缓冲厚度小，可以缩小包装件尺寸，降低物流成本；但是这种缓冲结构用材多，某些不需要缓冲的部位也用了同样厚度的材料，较浪费材料，包装成本大。其结构形式可以分为单壁式和组合式缓冲结构。按坑的厚度纸箱可分为四种：
The overall cushioning packaging method mainly refers to filling the cushioning material between the product and the carton, so that all sides are fixed by the cardboard, and adopting the comprehensive protection method for the product. Its advantages are that it is suitable for the packaging of products with complex shape and small batch, and the buffer material has a large contact area with the product, with small static stress, and can absorb large impact energy, with small buffer thickness, which can reduce the size of the package and reduce the logistics cost; however, this buffer structure uses more materials, and some parts that do not need buffer also use the same thickness of materials, which is more wasteful Materials, packaging costs. Its structure can be divided into single wall and combined buffer structure. According to the thickness of the pit, cartons can be divided into four types:
一、幼坑箱,又称为 E 坑箱,写法为 A9A,A9B,B9B 等,其是很薄的纸箱, 一般是纸盒.或者礼品箱礼品盒用，共 3 层纸.总厚度为 1.5-2.0 MM。
1、 Young pit box, also known as e pit box, written as a9a, a9b, b9b, etc., it is a very thin carton, generally carton. Or gift box, gift box, a total of 3 layers of paper. The total thickness is 1.5-2.0 mm.
二、单坑箱,写法为 K3K,K3A,A3A,A3B,B3B 等.一般用来做内箱.共 3 层纸.总厚度为 2.5MM。
2、 Single pit box, written as k3k, K3A, A3A, a3b, B3b, etc. it is generally used as inner box. It has three layers of paper. The total thickness is 2.5mm.
三、双坑箱,这是通常用得比较多的纸箱.写法K=K,K=A,A=A,A=B,A=C,B=B 等.共 5 层纸.总厚度为 5MM。
3、 Double pit box, this is usually used more cartons. Writing k = k, k = a, a = a, a = B, a = C, B = B, etc. a total of 5 layers of paper. The total thickness is 5mm.
四、三坑箱,写法为 A 三 A,A 三 B,B 三 B,这是纸箱中较厚的纸箱.一般用于包装易碎及较重的物品,如服装/五金等.因其抗破 强度较好.单价中也是较高的.共 7 层纸,总厚度为 7.5MM较
4、 Three pit box, written as a three a, a three B, B three B, this is the thicker carton in the carton. It is generally used for packing fragile and heavy items, such as clothing / hardware, etc. because of its good bursting strength, the unit price is also higher. There are 7 layers of paper, with a total thickness of 7.5mm
