Self-adhesive labels, also called self-adhesive labels, are mainly used for liquid washing products and popular personal care products; film materials are mainly used for mid-to-high-end daily chemical products. Popular personal care products and household liquid cleaning products occupy a large proportion of the market, so corresponding paper materials are used more. The so-called "flying label" in die-cutting refers to the phenomenon that the label is brought up along with the waste discharge edge during the die-cutting process. The phenomenon of "flying mark" in die-cutting is very common in daily production. Serious "flying mark" phenomenon will cause a waste of raw materials and bring a lot of trouble to the post-processing process. The reasons that lead to "flying marks" in die-cutting include: the release force of the material is too low (the temperature is too low), and the bonding force between the surface layer of the self-adhesive material and the backing paper is called the release force.
If the release force of the self-adhesive material is too low, it is likely to cause "flying marks" during the die-cutting process. It should be noted here that the release force of many self-adhesive materials changes under the influence of temperature. Generally speaking, as the temperature increases, the release force increases and vice versa. If the temperature in the workshop is too low in winter, it is very likely that the release force of the self-adhesive material will decrease, resulting in "flying marks" in die cutting. Generally, it is recommended that the production temperature in the workshop should not be lower than 15 degrees Celsius. If the "flying mark" phenomenon still occurs above this temperature, you can consider whether it is a quality problem with the self-adhesive material; there is too much residual glue on the die-cutting knife, and residual glue will gradually accumulate on the knife during the die-cutting production process. If the residual glue accumulates to a certain extent, the edges of the labels will be brought up, which is equivalent to pre-stripping the die-cut labels. In this way, when the waste is discharged, the waste edge will easily bring up the label, causing "flying marks" in the die-cutting. Therefore, attention should be paid to timely cleaning of the residual glue on the blade. You can also use the method of padding sponge on the blade to prevent the blade from pre-peeling the label. If necessary, you can also spray some silicone oil spray on the blade to reduce the amount of residual glue on the blade.
