Why is label printing prone to warping and unsteadiness in winter We mainly propose analysis and solutions from the following aspects
1. the ambient temperature for the printing of self-adhesive labels is too low. The minimum temperature for the use of water-based adhesive for self-adhesive labels cannot be lower than 10 ℃. Below this temperature, the adhesive will freeze due to low temperature, and the glue can not be quickly adhered to the product. The solution is to choose water-based glue as much as possible in low temperature weather. If hot melt adhesive must be selected, a heating device shall be added before labeling, The problem can be solved by preheating the label first and then pasting the self-adhesive label for printing;
2. the surface lamination tension of self-adhesive label printing production is too large, and the printing factory does not adjust the surface lamination pressure during production, resulting in excessive tension. When it is pasted on the product surface, the edge will be warped due to the tension of the film surface itself;
3. the printing material of self-adhesive label is not selected correctly. When selecting materials for label printing production, we should consider whether the surface of the pasted product is flat or curved, frosted or smooth,
For example, when selecting curved surface materials, it is necessary to select materials with relatively soft label materials, such as PP and PE, which are good choices. For example, if the surface of the product to be pasted is rough, it is necessary to select self-adhesive label printing with relatively thick glue.
A small self-adhesive label printing also has a lot of knowledge. If you want to avoid detours, you need to choose a formal and professional printing factory like Kecheng label company. With many years of self-adhesive label printing experience, you can provide improvement and solutions for your products, so that you have no worries at home.
