0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Many printing and packaging industry color boxes will appearBox glueThe phenomenon of glue explosion and box explosion has caused great losses, but there is no good way to avoid and reduce! Because the printing and packaging plant did not find out the cause from the root cause, things happened one after another. Shandong Ruiyi Yinghua New Materials Co., Ltd. is engaged in researching, studying, analyzing, and cooperating with the majority of peers because of the development of sealing glue series products, and the contact and research on carton bonding problems.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Several factors causing problems with paste glue:

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 1. Improper operation can be modified in three ways

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; ①Pay attention to the amount of glue-the amount of glue is small and cannot be effectively bonded. For thicker paper and boxes with greater rebound force, Increasing the amount of glue is based on the principle that the glue is not extruded.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; ②Insufficient pressure-increase the pressure, use a mechanical flattening machine and an air pump to flatten the machine. For uneven color boxes and special-shaped color boxes, pay attention to 5-10 positive and negative positions to lay flat packs to allow effective and seamless contact between boxes.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; ③Glue moisture layer: Before using, customers should pay attention to mixing well, because the glue has many raw materials and the specific gravity is different, long-term storage will cause precipitation Layered.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 2. The choice of box glue is very important, scientific use is more important

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; ① There is no glue to do anything. Therefore, customers must choose and use glue scientifically, for example: compound film sealing glue can not be used to bond the surface UV oil carton; glazing glue can not be used to bond the pasted film carton.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; ②Cold and cold product packaging cartons, as well as export carton hot regional cartons, customers should choose corresponding Adhesives with high temperature resistance and aging resistance are actively communicated with the production unit, not blindly selected.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 3. Risk awareness of factory operators and administrators

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; It should be noted that small batch samples should be made before mass production of color boxes to ensure process quality control and prevent the risk of glue box explosion 1. Prevent problems before they happen. When using new materials and different batches of raw materials, new process products should be tested.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 4. Problems with key raw materials such as paper and optical film

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; There are many kinds of specifications such as paper and optical film. This is one of the raw materials commonly used in the printing industry and widely used. It affects the entire color box, and there are raw materials that are more negligent and more difficult to test, so the following aspects should be used to prevent problems.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 1) Purchase double-sided corona film from the film factory and require a corona value of 30 or above Or, install a plasma processor on the folder gluer to corona the light film on the surface of the carton. The surface of the matte film is rough, and the dyne value is above 30. The matte film carton has basically not experienced a blowout phenomenon.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 2) Use a blade to lightly scrape to detect whether the paper has fallen off, and whether the paper is coated or not.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 3) Use glue to check whether the bond between printing glazing and paper is strong After drying, tear open the carton and take down the varnish side, it means that the varnish is off).
