The horn paper is multi-layer bonded with the horn tube paper, and then pressed down from the horn protector. The angle is 90 ° and the surface is smooth. It is mainly used for inner packing of steel. Prevent the steel edge from scratching the outer antirust paper, enhance the edge support of the package, and protect the overall package strength. A triangular opening is arranged in the longitudinal direction of the bottom surface, so that the paper angle can form a straight shape, which is used to wrap the angle of the metal plate edge, and can be bent as the edge of the inner hole. Outer circle and different diameter metal roller. Corner protector. The dual use of one thing improves versatility and saves raw materials.

　　紙包裝容器因其成本低、資源節(jié)約、機(jī)械加工性能好、機(jī)械化量產(chǎn)、易印刷、無(wú)害、易回收等優(yōu)點(diǎn)受到消費(fèi)者的青睞，更符合綠色環(huán)保的理念。提倡在包裝材料中使用紙質(zhì)包裝。然而，在紙包裝不斷發(fā)展的過(guò)程中，人們也發(fā)現(xiàn)了紙包裝的缺點(diǎn)，如承載差，紙箱包裝易變形。在發(fā)展過(guò)程中面對(duì)這些問(wèn)題，紙角在紙包裝中逐漸出現(xiàn)，尤其是蜂窩盒包裝和瓦楞盒包裝。在整個(gè)開(kāi)發(fā)過(guò)程中，紙角開(kāi)始改變其形狀，包括周?chē)慕恰⒔?、u形角等。

　　Paper packaging container is favored by consumers because of its low cost, resource saving, good mechanical processing performance, mechanized mass production, easy printing, harmless and non-toxic, easy recycling and other advantages, and more in line with the concept of green environmental protection. It is recommended to use paper packaging in packaging materials. However, in the process of the continuous development of paper packaging, people also found the shortcomings of paper packaging, such as poor load, cartons packaging deformation. In the process of development, facing these problems, paper corners gradually appear in paper packaging, especially in honeycomb box packaging and corrugated box packaging. In the whole development process, the paper angle began to change its shape, including the surrounding angle, angle, U-shaped angle and so on.

　　由于紙角可以綁在一起，使整個(gè)包裝越來(lái)越堅(jiān)固，貨物被固定在托盤(pán)上，以保護(hù)產(chǎn)品及其邊緣。產(chǎn)品在加工過(guò)程中受到保護(hù)和支持，可以根據(jù)客戶(hù)的不同規(guī)格進(jìn)行定制。切割等特性在產(chǎn)品包裝中的應(yīng)用越來(lái)越廣泛。

　　As the corners of the paper can be tied together to make the whole package stronger and stronger, the goods are fixed on the pallet to protect the product and its edge. Products are protected and supported in the processing process, and can be customized according to different specifications of customers. Cutting and other characteristics are more and more widely used in product packaging.
