瓦楞紙箱的主要功能是保護內(nèi)裝物不受環(huán)境(物理的、化學的，機械的、氣候的等)的損壞。原標準將瓦楞紙箱分成三類，也是三個等級。主要是按照出口、內(nèi)銷及內(nèi)裝物的貴重程度來劃分。隨著目前國內(nèi)外貿(mào)易的發(fā)展趨勢及經(jīng)濟的化趨勢，原來的劃分方法已經(jīng)不夠科學與合理。
The main function of corrugated box is to protect the contents from environmental damage (physical, chemical, mechanical, climatic, etc.). The original national standard divides corrugated boxes into three categories, which are also three grades. It is mainly divided according to the value of export, domestic sales and contents. With the development trend of domestic and international trade and economic internationalization, the original division method is not scientific and reasonable.
新修訂的瓦楞紙板標準擬將紙板劃分為“優(yōu)等品”和“合格品”，對于瓦楞紙箱來講也不盡合適。如果劃分等級應該按照其將遇到的流通環(huán)境條件的嚴酷程度劃分。而且作為標準，應該對瓦楞紙箱提出一個限度的要求即可，但考慮到我國的現(xiàn)狀及使用習慣，將其劃分為兩類。即：1類紙箱主要用于儲運流通環(huán)境比較惡劣的情況；2類紙箱主要用于流通環(huán)境較好的情況。
The newly revised corrugated board standard is intended to divide cardboard into "superior products" and "qualified products", which is not suitable for corrugated boxes. If it is classified, it should be classified according to the severity of the circulation environment conditions it will encounter. And as a national standard, corrugated boxes should be put forward a minimum requirement, but considering the current situation and use habits of our country, it is divided into two categories. That is: the first type of cartons is mainly used for the storage and transportation of relatively bad circulation environment; the second category of cartons is mainly used for the better circulation environment.
⑴瓦楞紙板的瓦楞型號瓦楞的型號，按楞高分為A,B,C,E四類，不同瓦楞紙板的力學性能也不同。A型瓦楞紙板的平面壓力高，抗壓強度較大，B型則相反，C型的平面壓力、垂直壓力、平行壓力和緩沖力都較好；瓦楞紙板間的厚度，A型大，C型次之，B型再次之，E型小，由于厚度小的紙板加工折彎較容易，因此，B形瓦楞紙廣泛用于對箱的耐壓強度要求不高的包裝運箱.根據(jù)瓦楞紙板的不同力學性能，單面瓦楞紙箱用A或C型為好，雙面瓦楞紙箱用A,B型或B,C型相結合為宜，接近外表面的用B型，能起到抗沖擊作用。A,B型或B、C型相結合，可提高紙箱物理機械性能；從印刷適性上比較，B型和C型均利于印刷。
(1) the corrugated model of corrugated board, the model of corrugated board, according to the corrugated high score of a, B, C, e four categories, different corrugated board mechanical properties are also different. Type a corrugated board has the highest plane pressure and higher compressive strength, while type B has the opposite. Type C has better plane pressure, vertical pressure, parallel pressure and buffer force. The thickness between corrugated boards is the largest in type A, followed by type C, followed by type B, and type E is the smallest. Due to the easier processing and bending of paper board with small thickness, B-shaped corrugated paper is widely used for the compressive strength requirements of boxes According to the different mechanical properties of corrugated paperboard, it is better to use type A or C for single-sided corrugated box, type A, type B or type B and type C for double-sided corrugated box, and type B for those close to the outer surface, which can play an impact resistance role. A. Type B or combination of B and C can improve the physical and mechanical properties of cartons; from the perspective of printability, both type B and type C are conducive to printing.
⑵瓦拐紙箱的箱形在保證紙箱質量的前提下，應盡量節(jié)約紙箱加工材料和包裝費用。比如.容積相同的紙箱，采用長：寬：高為2:1:2時省料，比例為1:1:1時費料。因此，應盡量避免采用正方形的箱.還要照顧到產(chǎn)品對箱容積的利用率，箱對卡車、火車車廂容積的利用率以及倉儲運抽時堆垛的穩(wěn)定性.
(2) under the premise of ensuring the quality of the carton, the processing materials and packaging costs of the corrugated box should be saved as much as possible. For example, the same volume of cartons, using the length: width: height of 2:1:2 is the most economical material, and the ratio of 1:1:1 is the most expensive. Therefore, we should avoid using square boxes as far as possible. We should also take into account the utilization rate of the product to the container volume, the utilization rate of the box to the volume of the truck and train carriage, and the stability of the stacking during the storage and pumping
據(jù)我所知重型瓦楞紙箱又分為單瓦，雙瓦兩種，雙瓦楞有兩層瓦楞紙，如:AB,bc,be等,而單瓦楞只有一層瓦楞，分:A,C,B,E,緩沖性依次遞減,而挺度級平整度依次增加.雙瓦楞的邊壓強度和耐破裂強度均高于單瓦楞.要求比較高的紙箱都采用雙瓦楞紙箱。都是紙質的，原料為純木漿和回收木漿，強度不同，造價也不同。
As far as I know, heavy-duty corrugated boxes are divided into single and double corrugated. Double corrugated boxes have two layers of corrugated paper, such as: AB, BC, be, etc., while single corrugated boxes have only one layer of corrugated paper, divided into a, C, B, e. the buffering capacity decreases in turn, while the stiffness level flatness increases in turn. The edge pressure strength and rupture strength of double corrugated boxes are higher than that of single corrugated boxes. They are all paper-based, and the raw materials are pure wood pulp and recycled wood pulp, with different strength and different cost.
