1、 Functional differences

重型紙箱耐破損，防水防潮，耐高壓; 普通紙箱耐破損，防水，防潮，壓力指數(shù)較低。重型紙箱的破裂強度為44±4kgf / cm2，普通紙箱的破裂強度通常為10±4kgf / cm2; 重型紙箱可以裝載50公斤2噸，普通紙箱通常不單獨裝載，而是在壓力下裝載; 硬紙板珠可以滑落到硬紙板上，而普通硬紙板則直接滲入硬紙板中，硬紙板變軟。

Heavy duty cartons are resistant to damage, water, moisture and high pressure; ordinary cartons are resistant to damage, water, moisture and low pressure index. The rupture strength of heavy-duty cartons is 44 ± 4kgf / cm2, and that of ordinary cartons is usually 10 ± 4kgf / cm2; heavy-duty cartons can carry 50 kg to 2 tons, while ordinary cartons usually do not load separately, but under pressure; cardboard beads can slide onto the cardboard, while ordinary cardboard can directly penetrate into the cardboard, and the cardboard becomes soft.

二、與應用的區(qū)別：

2、 Difference from application:

重型紙箱應包裝在汽車部件，醫(yī)療設備，大件物品，機柜，大型電視機中，不能承受壓力和包裝的產(chǎn)品; 我們每天在運輸過程中看到的包裝都使用普通的盒子。只需要解決包裝物品，例如水果，衣服等日常用品。

Heavy duty cartons should be packed in auto parts, medical equipment, large items, cabinets, large TV sets, products that can not bear pressure and packaging; the packaging we see in the transportation process every day uses ordinary boxes. Only need to solve packaging items, such as fruit, clothing and other daily necessities.

三、與物質(zhì)的區(qū)別。

3、 It's different from matter.

普通紙箱：是由三層紙制成的紙箱，如“啤酒紙箱”，“牛奶箱”，“方便面箱”，它們分別是“外面紙，中間瓦楞紙和更里面的紙板紙”。承重比較小。瓦楞紙一般采用BLEN或ELEN重型紙箱：有五層紙箱，也稱為“五層紙箱”，由面紙，瓦楞紙，心形紙，瓦楞紙，硬紙板制成。一般用于食用油四包裝盒和家用電器。

Ordinary carton: it is made of three layers of paper, such as "beer carton", "milk carton" and "instant noodle carton". They are "outer paper, middle corrugated paper and innermost cardboard". The load bearing is relatively small. Corrugated paper generally uses blen or Elen heavy-duty cartons: there are five layers of cartons, also known as "five layers of cartons", made of tissue paper, corrugated paper, heart-shaped paper, corrugated paper, cardboard. It is generally used in four packaging boxes of edible oil and household appliances.

重型紙箱：一般為5層以上，外層由Meica紙板制成，芯紙由高瓦楞紙制成，硬度高，紙板厚，層數(shù)大。

Heavy duty carton: generally more than 5 layers, the outer layer is made of meica paperboard, the core paper is made of high corrugated paper, with high hardness, thick paperboard and large number of layers.

在紙箱裝載方面，不僅紙箱的結構，而且所用各種紙張的厚度和強度也對紙箱的承重能力有很大的影響。

In terms of carton loading, not only the structure of the carton, but also the thickness and strength of all kinds of paper used have a great impact on the load-bearing capacity of the carton.
