Paper corner guard has the characteristics of compression resistance, moisture resistance, light weight, environmental protection and low cost. It provides a strong overall packaging for pallet transportation, can enhance the stacking strength of cartons, avoid damage to the goods by the packing belt, effectively maintain the edges and corners of the goods, and strengthen the goods on the pallet. Especially in line with the requirements of environmental protection, the recovery rate of 100%, is a new type of green packaging materials in all walks of life.

紙護角逐漸發(fā)展起來，它們綠色環(huán)保，人們所要求的環(huán)保包裝產(chǎn)品。 由于其高的抗壓強度和抗扭強度等物理性能以及強大的包裝適應性，已被廣泛用于五金，電子，食品，建材等各個行業(yè)的產(chǎn)品包裝和運輸。 隨著紙護角保護行業(yè)的不斷發(fā)展和完善，越來越多的公司將其添加到商品包裝中。 那么，我們?nèi)绾螀^(qū)分它的質(zhì)量呢？

With the development of paper corner guards, they are green and environmentally friendly, and meet people's requirements for environmental protection packaging products. Due to its high compressive strength and torsional strength and strong packaging adaptability, it has been widely used in the packaging and transportation of products in various industries, such as hardware, electronics, food, building materials, etc. With the continuous development and improvement of paper corner protection industry, more and more companies add it to the commodity packaging. So, how do we distinguish between its quality?

1.外觀：，我們需要檢查紙護角的表面平整度。 紙護角由一層牛皮紙制成，其中有多層線軸和紙盒被粘合和壓制。 由于牛皮紙是粗糙紙，因此在生產(chǎn)過程中對紙護角的表面光澤沒有特殊要求，但角保護器的表面須平坦。 如果生產(chǎn)的護角板表面不平坦，則護角板非常不牢固。

1. Appearance: first of all, we need to check the surface flatness of the paper corner guard. The paper corner guard is made of a layer of kraft paper, in which multi-layer bobbins and cartons are glued and pressed. Because kraft paper is rough paper, there is no special requirement for the surface gloss of paper corner protector in the production process, but the surface of corner protector must be flat. If the surface of the corner plate is not flat, the corner plate is very weak.

2.觸感：與其他紙包裝產(chǎn)品相比，紙護角具有更高的硬度和一定的厚度。 好的紙護角觸感更平滑，更硬，更難捏。 另外，紙護角的硬度和厚度是衡量角保護器質(zhì)量的重要參數(shù)。 高硬度不一定是高硬度，而厚硬度不一定是高硬度。 僅兩個要求的合格人員才被視為合格人員。

2. Touch: compared with other paper packaging products, paper corner guard has higher hardness and certain thickness. A good paper horn guard feels smoother, harder and harder to pinch. In addition, the hardness and thickness of paper corner protector are important parameters to measure the quality of angle protector. High hardness is not necessarily high hardness, while thick hardness is not necessarily high hardness. Only qualified personnel who meet both requirements are considered qualified personnel.

3.稱重：稱重紙護角是檢查角保護器質(zhì)量的相對簡單有效的方法之一。 重量是檢查紙張角落的障礙，不能偽造紙張質(zhì)量，也是根本的。 在紙張密度方面，劣質(zhì)紙護角與高質(zhì)量紙護角不同。 只要知道，他們就會知道紙護角是否是假的。

3. Weighing: weighing paper corner guard is one of the relatively simple and effective methods to check the quality of angle protector. Weight is an obstacle to checking the corners of the paper. It is also fundamental that the quality of paper can not be forged. In terms of paper density, poor quality paper corner guard is different from high quality paper corner guard. As long as they know, they will know whether the paper corner guard is fake.
