The paper corner protector is made of three kinds of raw materials: bobbin paper, kraft paper and white latex, which are pressed by the machine corner protector. It is green, environmentally friendly, less pollution, low cost, easy to recycle and has a wide range of uses.

紙張角部常見質(zhì)量問題：層次、空邊、壓裂。

Common quality problems in paper corners: layer, empty edge and fracturing.

一般情況下，紙面上的角部會(huì)出現(xiàn)分層，這是由于輥筒壓力不足造成的；而空邊則是因?yàn)榕Ｆぜ堅(jiān)谶M(jìn)入輪輥筒之前沒有用紗管紙包住，白乳膠未涂平均也是原因之一。如果紙護(hù)角處出現(xiàn)壓破質(zhì)量問題，通常是膠量過大或壓輪壓力過大，此時(shí)需要調(diào)整。

Generally, delamination occurs at the corners of the paper, which is caused by insufficient roller pressure; The empty edge is because kraft paper is not wrapped with bobbin paper before entering the wheel roller, and the average uncoated white latex is also one of the reasons. If there is a crushing quality problem at the corner of the paper guard, it is usually too much glue or too much pressure on the pressure roller, which needs to be adjusted at this time.

涂抹白乳膠一般有兩種方法，噴膠或刮膠；兩者各有利弊。后者適合高品質(zhì)的紙張，能平均噴涂，節(jié)約成本，如果紙張質(zhì)量不好就不能使用。多數(shù)選擇后者，可將紙張完全浸入膠池中；但這種方法的缺點(diǎn)是：一是很費(fèi)膠，二是商品干燥速度慢。在刮膠的時(shí)候盡量選擇乳膠管會(huì)比較好，不使用硅膠管，刮膠的作用要比乳膠管稍差一點(diǎn)。

There are generally two methods to apply white latex, spraying or scraping; Both have advantages and disadvantages. The latter is suitable for high-quality paper, which can be sprayed evenly and save cost. If the paper quality is not good, it can not be used. Most choose the latter, and the paper can be completely immersed in the glue pool; But the disadvantages of this method are: first, it costs a lot of glue, and second, the drying speed of goods is slow. It is better to choose latex tube when scraping glue. Silicone tube is not recommended. The effect of scraping glue is slightly worse than that of latex tube.

隨著包裝行業(yè)競(jìng)爭(zhēng)的日益激烈，所以在市場(chǎng)上出售的紙護(hù)角出現(xiàn)了以次充好、偷工減料的情況并不罕見，因此顧客購(gòu)買時(shí)一定要分辨好質(zhì)量的好壞，對(duì)于那些有質(zhì)量問題的紙護(hù)角，再的也不要購(gòu)買！

With the increasingly fierce competition in the packaging industry, it is not uncommon for paper corner guards sold in the market to be shoddy and shoddy. Therefore, customers must distinguish good quality when buying. For those paper corner guards with quality problems, don't buy them at a lower price!
