经常看到纸箱在我们生活中,很多事情,和日常必需品,电器是用纸盒包装,以保护他们,在使用的过程中,容易处理,可以回收使用绿色的要求,但各种各样的纸箱也多种多样,瓦楞纸箱属于其中之一,是一种使用较广泛的包装产品,起到美化商品,宣传商品的作用,装卸运输。
It is often seen that cartons are used in our daily life for many things and daily necessities. Electrical appliances are packed in cartons to protect them. In the process of use, they are easy to handle and can be recycled to meet the requirements of environmental protection. However, there are many kinds of cartons. Corrugated cartons belong to one of them. They are widely used packaging products, which play the role of beautifying commodities, publicizing commodities, loading, unloading and transportation 。
人们对瓦楞纸箱的功能要求越来越高。瓦楞纸箱具有多种功能，合理的纸箱形状和尺寸设计是非常重要的。瓦楞纸板自动生产线、印刷工艺、后处理及成型工艺;印刷工作基本实现了印刷、开槽、模切、粘盒、包装的一次成型自动化。瓦楞纸板强度要求1.1:边压强度:沿瓦楞纸板方向，单位长度瓦楞纸板前压送能承受的较大力。单位:N / m。
People have higher and higher requirements for the functions of corrugated boxes. Corrugated box has many functions. It is very important to design the reasonable shape and size of the box. Corrugated board automatic production line, printing process, post-processing and forming process; printing basically realizes the one-time forming automation of printing, slotting, die-cutting, gluing and packaging. Corrugated board strength requirements 1.1: edge pressure strength: along the direction of corrugated board, the unit length of corrugated board can bear more pressure before feeding. Unit: n / m.
边缘抗压强度=表面纸复合环抗压强度+复合瓦楞纸复合环抗压强度*收缩率(可靠)，实际试验值宜大于理论计算值。1.2:破断强度:瓦楞纸板在开裂前单位面积所能承受的较大外力均匀增大。单位:公斤/平方厘米。纸板的断裂强度=面纸的断裂强度+纸介质情况下的断裂强度+底纸的断裂强度*由于制造过程中的某些强度损失,实际测试的断裂强度的计算值要小于1公斤/平方厘米。1.3:天津瓦楞纸箱冲压强度:新国标gb6544-1999了对纸板冲压强度的要求。
Edge compressive strength = surface paper composite ring compressive strength + composite corrugated paper composite ring compressive strength * shrinkage rate (safe and reliable), the actual test value should be greater than the theoretical calculation value. 1.2: breaking strength: the larger external force that the corrugated board can bear per unit area before cracking increases uniformly. Unit: kg / cm2. The breaking strength of the paperboard = breaking strength of the face paper + breaking strength of the paper medium + breaking strength of the base paper * due to some strength loss in the manufacturing process, the calculated breaking strength of the actual test should be less than 1 kg / cm2. 1.3: stamping strength of Tianjin corrugated box: the new national standard GB 6544-1999 has eliminated the requirement for the stamping strength of cardboard.
