當前，產品和物資流通是經濟活動中重要的組成部分，其以生產工廠為起點，以消費者為終點，包括了商品及包裝的運輸、中轉、裝卸、倉儲、陳列、銷售等環(huán)節(jié)。當今包裝新技術層出不窮，如緩沖防震包裝、集合包裝、顯竊啟包裝、兒童包裝、防偽包裝、保鮮包裝、真空包裝等。作為體現保護產品功能的紙箱緩沖結構，其在紙箱的特征設計中千變萬化。本文試就紙板折疊式緩沖包裝的結構進行分析。
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.
緩沖包裝方法主要指產品與紙箱之間填滿緩沖材料使所有面都被紙板固定，對產品采用保護的辦法。它的優(yōu)點是適合于形狀復雜，批量不大的產品包裝，并且緩沖材料與產品有較大的接觸面積靜應力小，并且能夠吸收大的沖擊能，緩沖厚度小，可以縮小包裝件尺寸，降低物流成本；但是這種緩沖結構用材多，某些不需要緩沖的部位也用了同樣厚度的材料，較浪費材料，包裝成本大。其結構形式可以分為單壁式和組合式緩沖結構。按坑的厚度紙箱可分為四種：
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,又稱為 E 坑箱,寫法為 A9A,A9B,B9B 等,其是很薄的紙箱, 一般是紙盒.或者禮品箱禮品盒用，共 3 層紙.總厚度為 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、單坑箱,寫法為 K3K,K3A,A3A,A3B,B3B 等.一般用來做內箱.共 3 層紙.總厚度為 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、雙坑箱,這是通常用得比較多的紙箱.寫法K=K,K=A,A=A,A=B,A=C,B=B 等.共 5 層紙.總厚度為 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,寫法為 A 三 A,A 三 B,B 三 B,這是紙箱中較厚的紙箱.一般用于包裝易碎及較重的物品,如服裝/五金等.因其抗破 強度較好.單價中也是較高的.共 7 層紙,總厚度為 7.5MM較
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
