Factors of poor sticky performance on carton:
1) Poor quality of glue: The stickiness of glue is the key factor that the adhesive label can be firmly attached or not. If the stickiness of glue is not strong enough, the adhesive label on the carton will fall off easily.
2) Expired or improper adhesive label material storage condition: If the adhesive label exceeds the shelf life, the glue performance will decrease. If the storage environment is humid, hot or exposed to sunlight, the stickiness will decrease.
3) Unclean surface on carton: Dust, oil, water or stains on the surface of the carton will reduce the stickiness or even cause the label to fall off.
4) Rough or uneven carton surface: The uneven surface of the carton will cause the adhesive label to not fit completely when pasted, and bubbles and warping will occur.
5) No labeling pressure on carton: Insufficient pressure during manual labeling, or too low labeling pressure of the automatic labeling machine.
6) Inappropriate labeling temperature: Too low a temperature will reduce the viscosity of the glue, decrease the fluidity, and make it difficult to fully bond with the surface of the carton.
How to solve it?
1) Select according to demand: For high viscosity requirements, choose adhesive with permanent strong adhesive glue. If the surface of the carton is rough, you can choose solvent adhesive or increase the coating amount of hot melt adhesive.
2) Choose high-quality products: Choose adhesives with well-known brands and reliable quality factory to ensure product quality and performance.
3) Check the shelf life: Before use, carefully check the shelf life and storage conditions of the adhesive to ensure its performance is good.
4) Clean the surface: Wipe the surface of the carton, remove dust, oil stains and water stains before labeling.

4) Clean the surface: Wipe the surface of the carton, remove dust, oil stains and water stains before labeling.
5) Control labeling pressure and speed: When labeling manually, press the sticker evenly to ensure that it fits the surface of the carton completely; when using an automatic labeling machine, adjust the appropriate labeling pressure and speed.
6) Choose a suitable labeling temperature: Generally speaking, the sticky performance is better during labeling temperature between 15℃-30℃. When the weather is cold, try to do labeling indoors.
