Paper corner protection products are now very common packaging materials. They can be used with cartons or pallets to protect the edges and corners of products from collision; Paper corner protection products are widely used in the packaging of furniture, electrical appliances, logistics and other fields. It has been on the market for about 10 years. Due to the low production threshold and simple raw materials, dozens or even hundreds of paper edge protection processing plants have sprung up in Qingdao. The paper corner protector is made of three kinds of raw materials: bobbin paper, kraft paper and white latex, which are pressed by the corner protector. It is green, environment-friendly and pollution-free, and does not produce any harmful substances in the production process.

纸护角

Paper corner

纸护角常见的质量问题有：分层，空边，压破。通常情况下，分层是由于滚轮的压力不够所致;而空边则是由于牛皮纸在进入道滚轮前未与纱管纸裹紧;白乳胶未涂抹均匀也是原因之一。若出现压破的现象，通常是胶量太大或者压轮压力太大;这时需要调一下。白乳胶涂抹的工艺通常为两种，喷胶或者刮胶;

The common quality problems of paper corner guards are: delamination, empty edge and crushing. Generally, delamination is caused by insufficient pressure of the roller; The empty edge is because the kraft paper is not tightly wrapped with the bobbin paper before entering the first roller; One of the reasons is that the white latex is not applied evenly. In case of crushing, the amount of glue is usually too large or the pressure of the pressure roller is too large; It needs to be adjusted at this time. There are usually two processes for white emulsion coating, glue spraying or scraping;

二者各有利弊。前者适用于的纸张，可以均匀喷洒，节省成本，若是纸张质量较差则不可以采用。大部分选择后者，可以把纸张完全侵泡在胶池里;弊端一是浪费胶，二是产品干的较慢。刮胶时尽量选择乳胶管会更好一些。硅胶管不建议用，刮胶性能稍微差一些。

Both have advantages and disadvantages. The former is suitable for high-quality paper and can be sprayed evenly to save cost. If the paper quality is poor, it can not be used. Most of them choose the latter, which can completely soak the paper in the glue pool; The first disadvantage is the waste of glue, and the second is that the product dries slowly. It will be better to choose latex tube when scraping glue. Silicone tubes are not recommended. The scraping performance is slightly worse.
