The color of paper corner protection is generally selected as the nature of paper, which is good for cost control and environment maintenance. The appearance shall be clean and tidy, and there shall be no obvious defects such as oil stain, water stain, sticky mark and speckle, so as to avoid pollution to the goods being maintained. The paper corner cutting edge should be uniform, can not show obvious burr. The surface of paper corner guard should be flat, the angle of each meter of paper corner guard should not be greater than 90 degrees, and the longitudinal bending should not be greater than 3 mm.

外表不允許呈現(xiàn)裂紋,邊角不能有松軟或開裂現(xiàn)象,邊角兩邊的尺寸誤差小于兩毫米，外面和里面各接觸面的涂膠要平均充沛，粘接結(jié)實(shí)。

Cracks are not allowed on the surface, and the edges and corners are not allowed to be soft or cracked. The size error of both sides of the corner is less than 2mm. The external and internal contact surfaces should be evenly coated with sufficient glue and firmly bonded.

不能呈現(xiàn)有離層脫膠的現(xiàn)象。外形和用處都沒(méi)有什么改動(dòng)，只是直條形，用作紙箱等的護(hù)邊物。但是，隨著需求的不時(shí)增加，其運(yùn)用范圍也在不時(shí)地?cái)U(kuò)展，術(shù)請(qǐng)求和外觀請(qǐng)求關(guān)于紙護(hù)角的技比方從之前作為紙箱護(hù)邊物開展到作為鋼卷等桶形物體護(hù)邊物的環(huán)繞護(hù)角。U型護(hù)角作為紙護(hù)角的另一種變形，其運(yùn)用量也正在不時(shí)上漲。

There is no phenomenon of delamination and degumming. There is no change in the shape and use, but the straight strip is used as the edge protection for cartons and so on. However, with the increasing demand from time to time, the scope of its application is also expanding from time to time. The technology of paper corner protection in technical request and appearance request is developed from the former as carton edge protector to the surrounding corner guard as barrel object edge guard such as steel coil. As another deformation of paper corner guard, U-shaped corner guard is increasing from time to time.

往常，U型護(hù)角主要用于紙托盤的消費(fèi)。與V型護(hù)角相比，U型護(hù)角占有很大的優(yōu)勢(shì)。紙托盤運(yùn)用U型護(hù)角能增加紙托盤的承重才能，也便當(dāng)了紙托盤的加工消費(fèi)，進(jìn)步消費(fèi)紙托盤的效率。具有可將產(chǎn)品束在一同使整體包裝愈加堅(jiān)實(shí)結(jié)實(shí)，把貨物固定在托盤上起到維護(hù)產(chǎn)品及其邊緣的作用，在搬運(yùn)過(guò)程中維護(hù)和支撐產(chǎn)品及可依據(jù)客戶的不同規(guī)格及請(qǐng)求量身定做等優(yōu)點(diǎn)，在產(chǎn)品包裝中應(yīng)用越來(lái)越普遍。

Usually, U-shaped corner guard is mainly used for paper tray consumption. Compared with V-type corner guard, U-shaped corner guard has great advantages. The use of U-shaped corner guard can increase the load-bearing capacity of paper tray, facilitate the processing and consumption of paper tray, and improve the efficiency of consumption paper tray. It can bundle the products together to make the overall packaging more solid and solid, fix the goods on the pallet to maintain the products and their edges, maintain and support the products in the process of handling and can be customized according to different specifications and requests of customers, so it is more and more widely used in product packaging.

1、紙護(hù)角能夠有效起到維護(hù)產(chǎn)品外觀邊緣的作用。假如是一些框框之類的產(chǎn)品，假如可以對(duì)四角停止有效的裝置的話，常?？梢詭?lái)十分好的固定作用，關(guān)于我們的物流以及安放也可以起到十分好的效果。

1. Paper corner guard can effectively maintain the appearance edge of products. If it is some frame products, if it can stop the effective device on the four corners, it can often bring a very good fixed effect, and our logistics and placement can also play a very good effect.

2、紙護(hù)角具有減少疊放壓力的作用。在紙箱中，假如反復(fù)性安放產(chǎn)品的話，關(guān)于我們來(lái)說(shuō)常常會(huì)產(chǎn)消費(fèi)品壓碎等狀況。假如運(yùn)用這樣的一種紙護(hù)角的話，就可以在一定水平上減少這樣的難題。

2. The paper corner protector can reduce the stacking pressure. In cartons, if repeated placement of products, on our part, often produce consumer goods crushing and other conditions. If the use of such a paper corner guard, it can reduce the problem to a certain extent.
