        紙箱容易開膠脫膠的原因有哪些?

        來源:http://www.578114.com/ 時間:2021-12-11 發布人:admin
        紙箱開膠是常見的問題之一,嚴重影響紙箱的包裝和保護作用。紙箱定做廠家總結了幾點常見的紙箱開膠原因,有需要的朋友可以前來了解。
        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、紙箱的涂膠量不足,導致粘性不夠。
        1. The gluing amount of the carton is insufficient, resulting in insufficient viscosity.
        2、涂膠后加壓時間過長或過短都可能造成紙箱易開膠。
        2. Too long or too short pressurization time after gluing may cause the carton to open easily.
        3、如果紙箱有覆膜或過油,其表面張力就容易導致紙板與膠水粘合不牢。
        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、紙箱定做廠家告訴您,用于紙箱粘接的膠水質量不好,高低溫性能不平衡,低溫易脆,不耐高溫,也容易開膠。
        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.
        紙箱紙盒出現脫膠的現象是非常嚴重的,特別是即將用在或者準備用在包裝的紙箱紙盒上。因為他們都是同一批的,可能大部分會脫膠。紙箱紙盒包裝出現脫膠對于消費者而言也是件讓人很煩的事情,特別是急需,又暫時找不到膠水或者替代的物品。而且脫膠這種情況的發生,也很容易造成產品的損壞。今天紙箱紙盒廠家信益包裝就給大家分享一下,紙箱紙盒脫膠的原因。
        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.紙箱紙盒的粘合強度較差
        1. The adhesive strength of cartons is poor
        判斷紙箱紙盒的粘合好否,只要用手撕開粘合面,如果發現原紙面被剝壞,則說明紙頁粘合得好。如果發現楞峰粘合處無撕毛的紙纖維或呈白粉狀,則說明是假粘,這會造成紙箱的抗壓強度偏低,并影響到整個紙箱的強度,非常容易出現脫膠的現象。紙箱的粘合強度與紙張的等級、粘合劑的配制和制造設備及工藝操作有關。
        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.紙箱紙盒膠粘劑的耐低溫功能欠好
        2. The low temperature resistance of carton adhesive is not good
        有些紙箱紙盒的膠粘劑的耐低溫功能欠好,在5℃以下粘接力下降或消失,導致出現脫膠的現象。
        The low temperature resistance of some carton adhesives is not good, and the adhesive force decreases or disappears below 5 ℃, resulting in degumming.
        3.紙箱紙盒存放的時間過長
        3. Cartons are stored for too long
        糊紙箱紙盒的膠水本身的粘接時長上差,多數是因為在糊紙箱紙盒的膠水中加入了一些增塑劑,隨著時間的延長,增塑劑向紙基遷移從而導致膠層變硬、發脆以致產品脫膠。糊盒膠/封口膠中含有大量的不飽和鍵,導致產品的耐老化性能不好出現貯存期延長膠膜變脆,使產品脫膠。
        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.
        如果庫房潮濕,那么長時間貯存在其中,不但產品的濕度會超標,出現發霉的現象,而且產品也會出現脫膠。
        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、紙箱紙盒膠粘劑耐高溫性能不良
        4. Poor high temperature resistance of carton adhesive
        紙箱紙盒在夏天出現開膠。炎熱的夏天,粘好的禮品紙盒包裝在庫房或運輸車箱中也會出現彈開脫膠。這主要是因為該種糊盒膠的耐高溫性能不好,在50℃~60℃的溫度下出現了膠層變軟,強度變小,從而導致包裝盒脫膠。
        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.
