纸箱容易开胶脱胶的原因有哪些?

来源:http://www.liufangshun.com/ 时间:2021-12-11 发布人:admin
纸箱开胶是常见的问题之一,严重影响纸箱的包装和保护作用。纸箱定做厂家总结了几点常见的纸箱开胶原因,有需要的朋友可以前来了解。
Carton opening is one of the common problems, which seriously affects the packaging and protection of cartons. Carton custom manufacturers have summarized several common reasons for carton gluing. Friends in need can come to understand.
1、纸箱的涂胶量不足,导致粘性不够。
1. The gluing amount of the carton is insufficient, resulting in insufficient viscosity.
2、涂胶后加压时间过长或过短都可能造成纸箱易开胶。
2. Too long or too short pressurization time after gluing may cause the carton to open easily.
3、如果纸箱有覆膜或过油,其表面张力就容易导致纸板与胶水粘合不牢。
3. If the carton is covered with film or oil, its surface tension will easily lead to poor adhesion between the paperboard and the glue.
4、纸箱定做厂家告诉您,用于纸箱粘接的胶水质量不好,高低温性能不平衡,低温易脆,不耐高温,也容易开胶。
4. The carton manufacturer tells you that the glue used for carton bonding is of poor quality, unbalanced high and low temperature performance, brittle at low temperature, not resistant to high temperature, and easy to open.
纸箱纸盒出现脱胶的现象是非常严重的,特别是即将用在或者准备用在包装的纸箱纸盒上。因为他们都是同一批的,可能大部分会脱胶。纸箱纸盒包装出现脱胶对于消费者而言也是件让人很烦的事情,特别是急需,又暂时找不到胶水或者替代的物品。而且脱胶这种情况的发生,也很容易造成产品的损坏。今天纸箱纸盒厂家信益包装就给大家分享一下,纸箱纸盒脱胶的原因。
The phenomenon of degumming of cartons is very serious, especially on cartons to be used or ready to be used in packaging. Because they are all in the same batch, most of them may degumm. The degumming of carton packaging is also a very annoying thing for consumers, especially in urgent need, and there is no glue or substitute temporarily. And the occurrence of degumming is also easy to cause product damage. Today, Xinyi packaging, a carton manufacturer, will share with you the reasons for the degumming of cartons and cartons.
1.纸箱纸盒的粘合强度较差
1. The adhesive strength of cartons is poor
判断纸箱纸盒的粘合好否,只要用手撕开粘合面,如果发现原纸面被剥坏,则说明纸页粘合得好。如果发现楞峰粘合处无撕毛的纸纤维或呈白粉状,则说明是假粘,这会造成纸箱的抗压强度偏低,并影响到整个纸箱的强度,非常容易出现脱胶的现象。纸箱的粘合强度与纸张的等级、粘合剂的配制和制造设备及工艺操作有关。
To judge whether the carton is well bonded, just tear the bonding surface by hand. If the original paper surface is stripped, it means that the paper is well bonded. If it is found that there is no torn paper fiber or white powder at the ridge peak adhesion, it indicates that it is false adhesion, which will cause the low compressive strength of the carton and affect the strength of the whole carton, which is very prone to degumming. The adhesive strength of carton is related to the grade of paper, the preparation of adhesive, manufacturing equipment and process operation.
2.纸箱纸盒胶粘剂的耐低温功能欠好
2. The low temperature resistance of carton adhesive is not good
有些纸箱纸盒的胶粘剂的耐低温功能欠好,在5℃以下粘接力下降或消失,导致出现脱胶的现象。
The low temperature resistance of some carton adhesives is not good, and the adhesive force decreases or disappears below 5 ℃, resulting in degumming.
3.纸箱纸盒存放的时间过长
3. Cartons are stored for too long
糊纸箱纸盒的胶水本身的粘接时长上差,多数是因为在糊纸箱纸盒的胶水中加入了一些增塑剂,随着时间的延长,增塑剂向纸基迁移从而导致胶层变硬、发脆以致产品脱胶。糊盒胶/封口胶中含有大量的不饱和键,导致产品的耐老化性能不好出现贮存期延长胶膜变脆,使产品脱胶。
The bonding time of the glue itself of the pasted carton is poor, mostly because some plasticizers are added to the glue of the pasted carton. With the extension of time, the plasticizers migrate to the paper base, resulting in the hardening and brittleness of the adhesive layer and the degumming of the product. There are a lot of unsaturated bonds in the paste box glue / sealing glue, which leads to poor aging resistance of the product, prolonging the storage period, making the glue film brittle and degumming the product.
如果库房潮湿,那么长时间贮存在其中,不但产品的湿度会超标,出现发霉的现象,而且产品也会出现脱胶。
If the warehouse is wet and stored in it for a long time, not only the humidity of the product will exceed the standard and mildew will occur, but also the product will degumm.
4、纸箱纸盒胶粘剂耐高温性能不良
4. Poor high temperature resistance of carton adhesive
纸箱纸盒在夏天出现开胶。炎热的夏天,粘好的礼品纸盒包装在库房或运输车箱中也会出现弹开脱胶。这主要是因为该种糊盒胶的耐高温性能不好,在50℃~60℃的温度下出现了胶层变软,强度变小,从而导致包装盒脱胶。
Cartons and cartons appear to open in summer. In hot summer, the glued gift carton will also pop and degumm in the warehouse or transport trunk. This is mainly because the high temperature resistance of this paste box adhesive is not good. At the temperature of 50 ℃ ~ 60 ℃, the adhesive layer becomes soft and the strength becomes smaller, resulting in degumming of the packaging box.
