First of all, we seldom see that jewelry hardcover box factories use printing. In fact, it is not because of poor printing, but because many high-end gift boxes do not need printing to reflect the customization effect. However, in the production process of some jewelry packaging boxes, some bar codes and other things will be directly printed on stickers, Therefore, the printing process appears in front of everyone in another form. In fact, ordinary carton printing factories all know that if they want to suppress the smell brought by printing ink, the common practice is film coating. In fact, many bar code stickers do the same. Film coating does remove a lot of printing smell, However, there are some places that need to be printed, but there is no way to deal with them. Therefore, some customized packaging boxes contain non coated printing parts such as instructions and display drawings, which can smell a very exciting smell at the moment of opening the box

Then there is the familiar smell of glue. The glue here does not refer to the inner support glue introduced yesterday, but the high-end magnet sealing box made by some gift box manufacturers. It is very simple that the magnet itself can not be attached to the inner material cardboard of the carton by itself. The magnet can only be fixed to the carton by adding glue later, One disadvantage of this kind of magnetic sealed box is that for the smooth progress of construction period and machine scheduling, it generally does not wait until the glue is fully air dried, even if there is no peculiar smell for the time being, but once the paper is mounted on the field and the whole magnet is buried in it, a lot of weak peculiar smell gas will accumulate again, waiting for it to penetrate through the paper when the box is opened next time, This is often the criticism that many jewelry hardcover box factories are difficult to deal with
