Summer high temperature and humidity, usage issues with adhesive labels:
2023-07-09
Summer is a high incidence period for sticker labeling failures, among which wrinkles and bulges are common problems after paper type sticker labeling. So, what is the reason for the wrinkles and bulges in labeling?
1. Water loss during processing
To avoid this problem, the best way is to add water to the adhesive material during the processing. A humidifier can be placed at the equipment winding station to add moisture to the material base paper. It is best for enterprises with conditions to install a temperature and humidity control system in the workshop to ensure the normal moisture content of the label product.
2. Improper storage caused
Usually, self-adhesive labels are packaged in plastic bags or wrapped with heat shrink film after printing, which essentially isolates them from the external environment. But when summer comes, it often rains, and after the rain, the air humidity will suddenly increase. If the label is affixed at this time, it is easy to absorb moisture from the air and expand, leading to wrinkles and bulges.
Therefore, when storing finished products with self-adhesive labels in summer, it is necessary to pay attention and try to open the packaging 24 hours before labeling use, allowing the label and the object to be placed in the same environment for 24 hours, which is conducive to balancing the humidity of both and ensuring labeling quality. Especially when the object being labeled is a corrugated cardboard box, this operation must be done to ensure the effectiveness of the labeling.
